    Placental location and pregnancy outcomes in nulliparous women: A population-based cohort study2019In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 98, no 8, p. 988-996Article in journal (Refereed)
    Abstract [en]

    Introduction: The impact of placenta previa on pregnancy, delivery and infant outcomes has been extensively studied. However, less is known about the possible association of placental location other than previa with pregnancy outcomes. The aim of this study was to investigate if placental location other than previa is associated with adverse pregnancy, delivery and infant outcomes.

    Material and methods: This is a population-based cohort study, with data from the regional population-based Stockholm-Gotland Obstetric Cohort, Sweden, from 2008 to 2014. The study population included 74 087 nulliparous women with singleton pregnancies resulting in live-born infants, with information about placental location from the second-trimester ultrasound screening. The association between placental location (fundal, lateral, anterior or posterior) and pregnancy outcomes was estimated using logistic regression analysis. Odds ratios (OR) with 95% confidence intervals (95% CI) were calculated, and adjustments were made for maternal age, height, country of birth, smoking in early pregnancy, sex of the infant and in vitro fertilization. Main outcome measures were pregnancy, delivery and infant outcomes.

    Results: Compared with posterior placental location, fundal and lateral placental locations were associated with a number of adverse pregnancy outcomes, the most important being: very preterm birth (<32 weeks of gestation) (adjusted OR [aOR] 1.78, 95% CI 1.18-2.63 and aOR 2.12, 95% CI 1.39-2.25, respectively), moderate preterm birth (32-36 weeks of gestation) (aOR 1.23, 95% CI 1.001-1.51 and aOR 1.62, 95% CI 1.32-2.00, respectively), small-for-gestational-age birth (aOR 1.67, 95% CI 1.34-2.07 and aOR 1.77, 95% CI 1.39-2.25, respectively) and manual removal of the placenta in vaginal births (aOR 3.27, 95% CI 2.68-3.99 and aOR 3.27, 95% CI 2.60-4.10, respectively). Additionally, lateral placental location was associated with preeclampsia (aOR 1.30, 95% CI 1.03-1.65) and severe postpartum hemorrhage (aOR 1.42, 95% CI 1.27-1.82).

    Conclusions: Compared with posterior placental location, fundal and lateral placental locations are associated with a number of adverse pregnancy, delivery and infant outcomes.

    Sympathetic reactivity in late pregnancy is related to labour onset in women2011In: Stress, ISSN 1025-3890, E-ISSN 1607-8888, Vol. 14, no 6, p. 627-633Article in journal (Refereed)
    Abstract [en]

    Stress regulation during pregnancy is considered to be connected to the timing of labour initiation. Although increasing knowledge is emerging on the regulation of parturition, there is currently no way to predict the start of spontaneous labour in women. The main aim of this study was to assess pain threshold and the sympathetic nervous system response to cold pain in relation to the onset of labour in healthy pregnant women. Ninety-three pregnant women were recruited and assessed for skin conductance (SC) activity during a cold pressor test in gestational week 38. Pain threshold and cold endurance were also measured and the results were compared with data obtained from hospital records. Seventy-four women had a spontaneous labour onset and a valid SC measurement. SC activity during the cold pressor test decreased significantly with the number of days left to spontaneous parturition. This may indicate a gradual decrease in sympathetic autonomic nervous system reactivity even during the last weeks of pregnancy. Measuring SC activity during mild stress provocation is a rapid and non-invasive means to study variation in sympathetic reactivity during pregnancy, and may be useful in research on stress regulation in pregnancy and its relation to labour initiation.

    Risk of fistula formation and long-term health effects after a benign hysterectomy complicated by organ injury: A population-based register study2018In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 97, no 12, p. 1463-1470Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: There is a paucity of data on the impact of organ injury on long-term outcomes after a hysterectomy for benign indications. The aim of this study was to investigate fistula formation and patient-reported long-term health outcomes after organ injury at the time of a hysterectomy.

    MATERIAL AND METHODS: This was a population-based study of 22 538 women undergoing a hysterectomy between 2000 and 2014 in Sweden. Their medical history, characteristics of their surgery, and patient-reported outcomes were retrieved from Swedish national health and quality registers. Predictors for fistula formation were investigated with logistic regression and are presented as odds ratios with a 95% CI.

    RESULTS: Fistulas were reported in 7% of women with organ injuries, compared with 0.4% of those without organ injuries (adjusted odds ratio 15.29 [9.81-23.85]). Laparotomy and postoperative infection were associated with postoperative fistulas. Most of the women reported having better health 1 year after the hysterectomy, but 7% of those with organ injuries and 24% of those with fistulas reported deteriorated health, compared with 2% of women without injuries.

    CONCLUSION: Organ injury at the time of hysterectomy is associated with the development of fistulas involving the female genital tract and increases the proportion of women reporting deteriorated health 1 year after surgery.

    The risk of uterine rupture is not increased with single- compared with double-layer closure: a Swedish cohort study2015In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 122, no 11, p. 1535-1541Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE:

    To compare single- with double-layer closure of the uterus for the risk of uterine rupture in women attempting vaginal birth after one prior caesarean delivery.

    DESIGN:

    Cohort study.

    SETTING:

    Sweden.

    POPULATION:

    From a total of 19 604 nulliparous women delivered by caesarean section in the years 2001-2007, 7683 women attempting vaginal birth in their second delivery were analysed.

    METHODS:

    Data from population-based registers were linked to hospital-based registers that held data from maternity and delivery records. Logistic regression was used to estimate the risk of uterine rupture after single- or double-layer closure of the uterus. Results are presented as odds ratios (ORs) with 95% confidence intervals (95% CIs).

    MAIN OUTCOME MEASURE:

    Uterine rupture.

    RESULTS:

    Uterine rupture during labour occurred in 103 (1.3%) women. There was no increased risk of uterine rupture when single- was compared with double-layer closure of the uterus (OR 1.17; 95% CI 0.78-1.76). Maternal factors associated with uterine rupture were: age ≥35 years and height ≤160 cm. Factors from the first delivery associated with uterine rupture in a subsequent delivery were: infection and giving birth to an infant large for gestational age. Risk factors from the second delivery were induction of labour, use of epidural analgesia, and a birthweight of ≥4500 g.

    CONCLUSIONS:

    There was no significant difference in the rate of uterine rupture when single-layer closure was compared with double -layer closure of the uterus.

    Effect of remote cesarean delivery on complications during hysterectomy: a cohort study2017In: American Journal of Obstetrics and Gynecology, ISSN 0002-9378, E-ISSN 1097-6868, Vol. 217, no 5, p. 564.e1-564.e8, article id S0002-9378(17)30863-3Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Cesarean section is frequently performed worldwide, and follow-up studies reporting complications at subsequent surgery are warranted.

    OBJECTIVES: The aim of the study was to investigate the association between a previous abdominal delivery and complications during a subsequent hysterectomy, and to estimate the fraction of complications driven by the presence of adhesions.

    STUDY DESIGN: This was a longitudinal population based register study of 25354 women undergoing a benign hysterectomy at 46 hospital units in Sweden 2000-2014.

    RESULTS: Adhesions were found in 45 % of the women with a history of cesarean delivery. Organ injury affected 2.2 %. The risk of organ injury (aOR 1.74, 95 % CI 1.41-2.15) and post-operative infection (aOR 1.26, 95 % CI 1.15-1.39) was increased with prior cesarean section, irrespective of whether adhesions were present or not. The direct effect on organ injury by a personal history of cesarean delivery was estimated to 73 %, and only 27 % was mediated by the presence of adhesions. Previous cesarean was a predictor of bladder injury (aOR 1.86, 95 % CI 1.40-2.47) and bowel injury (aOR 1.83, 95 % CI 1.10-3.03) but not ureter injury. A personal history of other abdominal surgeries was associated with bowel injury (aOR 2.27, 95 % CI 1.37-3.78), and the presence of endometriosis increased the risk of ureter injury (aOR 2.15, 95 % CI 1.34-3.44).

    CONCLUSIONS: Prior cesarean delivery is associated with an increased risk of complications during a subsequent hysterectomy, but the risk is only partly attributable to the presence of adhesions. Previous cesarean delivery and presence of endometriosis were major predisposing factors of organ injury at the time of the hysterectomy whereas background and perioperative characteristics were of minor importance.

    Abdominal adhesions in gynaecologic surgery after caesarean section: a longitudinal population-based register study.2018In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 125, no 5, p. 597-603Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of the study was to evaluate the association between abdominal adhesions at the time of gynaecologic surgery and a history of caesarean delivery, and to investigate obstetric factors contributing to adhesion formation after caesarean section (CS).

    DESIGN: Longitudinal population-based register study.

    SETTING: Sweden.

    POPULATION: Women undergoing benign hysterectomy and/or adnexal surgery in Sweden, 2000-2014, with a previous delivery during 1973-2013 (n = 15 479).

    METHODS: Information about abdominal adhesions during gynaecological surgery, prior medical history, pregnancies and deliveries were retrieved from Swedish National Health and Quality registers.

    MAIN OUTCOME MEASURES: Adhesions.

    RESULTS: In women with previous CS, adhesions were present in 37%, compared with 10% of women with no previous CS [odds ratio (OR): 5.18, 95% confidence interval (CI): 4.70-5.71]. Adhesions increased with the number of caesarean sections: 32% after one CS; 42% after two CS and 59% after three or more CS (P < 0.001). Regardless of the number of CS, factors at CS such as age ≥35 years (aOR: 1.28, 95% CI: 1.05-1.55), body mass index (BMI) ≥30 [adjusted OR (aOR): 1.91, 95% CI: 1.49-2.45] and postpartum infection (aOR: 1.55, 95% CI: 1.05-2.30) increased the risk of adhesions.

    CONCLUSIONS: Presence of adhesions in abdominal gynaecological surgery is associated with women's personal history of caesarean delivery. The number of caesarean sections was the important predictor of adhesions; advanced age, obesity and postpartum infection further increased the incidence.

    TWEETABLE ABSTRACT: Repeat caesarean, age, obesity and infection increased the risk of pelvic adhesions after caesarean section.

    Maternal complications in settings where two-thirds of extremely preterm births are delivered by cesarean section2017In: Journal of Perinatal Medicine, ISSN 0300-5577, E-ISSN 1619-3997, Vol. 45, no 1, p. 121-127Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate the maternal complications associated with cesarean section (CS) in the extremely preterm period according to the gestational week (GW) and to indication of delivery. Study design: This is a retrospective case-referent study with a review of medical records of women who delivered at 22-27 weeks of gestation (n = 647) at two level III units in Sweden. For abdominal delivery, gestational length was stratified into 22-24 (n = 105) and 25-27 (n = 301) weeks. For comparison, data on women who underwent a CS at term were identified in a register-based database. Results: The rate of CS in extremely preterm births was 62.8%. There was no difference in the complication rates, but types of incisions other than the low transverse incision were required more often at 22-24 (18.1%) weeks than at 25-27 GWs (9.6%) (P = 0.02). Major maternal complications occurred in 6.6% compared with 2.1% in the extremely preterm and term CS, respectively (P < 0.01). A maternal indication of extremely preterm CS increased the risk of complications. Conclusions: Almost two-thirds of the births at 22-27 GWs had an abdominal delivery. No increase in short-term morbidity was observed at 22-24 weeks compared to 25-27 weeks. CS performed extremely preterm had more major complications recorded than cesarean at term. The complications are driven by the underlying maternal condition.

    Induction of twin pregnancy and the risk of caesarean delivery: a cohort study2015In: BMC Pregnancy and Childbirth, ISSN 1471-2393, E-ISSN 1471-2393, Vol. 15, article id 136Article in journal (Refereed)
    Abstract [en]

    Background: Complications are common in twin pregnancies and induction of labour is often indicated. Most methods for induction are used but data on risks related to induction methods are sparse. The aim of this study was to investigate the association between induction of labour and caesarean delivery in twin pregnancies, and to assess the influence of induction method. Methods: Cohort study of twin pregnancies >= 34 weeks, planned for vaginal delivery, from two University Hospitals in Sweden. Data were collected from medical records during the periods 1994 (Orebro) and 2004 (Uppsala) to 2013. During the study period there were 78,180 live born births and 1,282 were twin births. Women with previous caesarean section were excluded. Induction methods were categorized into amniotomy, oxytocin and cervical ripening (intra cervical Foley catheter or prostaglandin). Adjusted odds ratios (AOR) with 95 % confidence interval (CI) for caesarean section were calculated by logistic regression and were adjusted for parity, maternal age, gestational length, complications to the pregnancy, infant birth weight and year of birth. Spontaneous labour onsets were used as the reference group. The main outcome measure was caesarean section. Results: In 462 twin pregnancies, 220 (48 %) had induction of labour and 242 (52 %) a spontaneous labour onset. Amniotomy was performed in 149 (68 %) of these inductions, oxytocin was administered in 11 (5 %) and cervical ripening was used in 60 (27 %). The rate of caesarean sections was 21 % in induced and 12 % in spontaneous labours (p 0.01). The absolute risk of caesarean section following induction was: 15 % with amniotomy; 36 % with oxytocin and 37 % with Foley/prostaglandin. Induction of labour increased the risk of caesarean section by 90 % compared with spontaneous labour onset (AOR 1.9, 95 % CI 1.1-3.5) and, when cervical ripening was used, the risk increased more than two fold (AOR 2.5, 95 % CI 1.2-5.3). Conclusion: Induction of labour in twin pregnancies increases the risk of caesarean section compared with spontaneous labour onset, especially if Foley catheter or prostaglandins are required. However, approximately 80 % of induced labours are delivered vaginally.

    Elective induction of labor and the risk of cesarean section in low-risk parous women: a cohort study2013In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 92, no 2, p. 198-203Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE:

    To estimate the association between elective induction of labor and cesarean section in low-risk parous women, and to assess if the association is influenced by induction method.

    DESIGN:

    Cohort study.

    SETTING:

    University hospital in Sweden. Population Parous women without pregnancy complications or previous cesarean section, and with a planned vaginal term (37-41 weeks), singleton birth, in vertex position were included.

    METHODS:

    Information was collected from a local database containing prospectively entered antenatal and delivery data. Odds ratios for cesarean section were calculated using generalized estimating equations logistic regression and adjusted for parity, maternal age, gestational length, birthweight, use of epidural anesthesia and year of birth.

    MAIN OUTCOME MEASURE:

    Emergency cesarean section.

    RESULTS:

    Among 7973 pregnancies that fulfilled the inclusion criteria, 343 (4%) had an elective induction of labor. Intravenous oxytocin was administered in 5% of these inductions, amniotomy was performed in 62%, and a cervical ripening agent was used in 33%. Electively induced labor more than doubled the risk of cesarean section compared with spontaneous labor onset (OR 2.5, 95% 1.4-4.2) and this risk was more than tripled when cervical ripening was used (OR 3.6, 95% confidence interval 1.7-7.6).

    CONCLUSIONS:

    In low-risk parous women, electively induced labor has an increased risk of emergency cesarean section compared with spontaneous onset labor. This risk increase is more pronounced if cervical ripening agents are required. Women need to be counseled about these risks before elective induction of delivery is decided.

    St depression at caesarean section and the relation to oxytocin dose: a randomised controlled trial2010In: BJOG : an international journal of obstetrics and gynaecology, ISSN 1470-0328, Vol. 117, no 1, p. 76-83Article in journal (Refereed)
    Abstract [en]

    Objective To investigate whether there is a difference in occurrence of electrocardiogram changes suggestive of myocardial ischaemia between two different doses of oxytocin. Design Double-blind randomised controlled trial Setting University hospital in Sweden. Population A total of 103 healthy women undergoing elective caesarean section under spinal anaesthesia. Methods The participants were randomised to 5 or 10 units of oxytocin, given as an intravenous bolus. A Holter monitor was used to record electrocardiograms and non invasive blood pressure and heart rate (HR) was monitored. A blood sample was obtained 12-hour postoperatively. Main outcome measures Depression of the ST segment. Secondary outcomes: symptoms, Troponon I levels, mean arterial pressure (MAP), HR and blood loss. Results There was a significant difference in occurrence of ST depressions associated with oxytocin administration, 4 (7.7%) with 5 and 11 (21.6%) with 10 units, P < 0.05. The absolute risk reduction was 13.9% (95% confidence interval, 0.5-27.3). Decrease of mean MAP from baseline to 2 minutes differed, being 9 mmHg in the 5 unit group and 17 mmHg in the 10 unit group (P < 0.01). The increase in mean HR did not differ. Troponin I levels were increased in four subjects (3.9%). There were no differences in occurrence of symptoms, Troponin I levels, or estimated blood loss. Conclusion ST depressions were associated with oxytocin administration significantly more often in subjects receiving 10 units compared with 5 units. Interventions to prevent hypotension during caesarean section may reduce the occurrence of ST depressions on electrocardiograms.

    Assessment of pain in women randomly allocated to speculum or digital insertion of the Foley catheter for induction of labor2011In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 90, no 9, p. 997-1004Article in journal (Refereed)
    Abstract [en]

    Objective

    The primary aim was to assess pain subjectively and objectively in women during insertion of a Foley catheter for induction of labor. A secondary aim was to assess pain during cervical ripening and to evaluate maternal satisfaction.

    Design

    Randomized controlled trial. Setting. University hospital, Sweden. Population. Forty-two women undergoing induction of labor and cervical ripening with a Foley catheter.

    Methods

    Women were randomly allocated to digital (n=21) or to speculum (n=21) placement of a Foley catheter. A visual analogue scale (VAS) was used for subjective assessment of pain and, for objective measurements, a skin conductance algesimeter was used and the area under the curve (AUC) was calculated (mu Ss). Maternal satisfaction was evaluated in a questionnaire. Main outcome measures. Pain sensation during placement of the Foley catheter.

    Results

    There was a significant difference between groups in pain measurements during insertion of the Foley catheter. The speculum group had higher median pain scores than the digital group, VAS=5 vs. = 3 (p=0.03) and greater median AUC measurements: 1840 vs. 823 mu Ss (p=0.04). There was no difference in pain assessments during cervical ripening. Overall satisfaction scores were high and comparable between groups.

    Conclusion

    Digital placement of the Foley catheter is subjectively and objectively less painful compared to the use of a speculum. Digital placement should therefore be considered as an alternative in the management of these patients. Ripening of the cervix with the Foley catheter is well tolerated and the overall satisfaction rate among patients induced with this method is high.

    Analysis of malpractice claims with a focus on oxytocin use in labour2007In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 86, no 3, p. 315-319Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The objective of this study was to analyse the motives behind disciplinary action in obstetric malpractice cases concerning delivery, and to evaluate the frequency of inappropriate oxytocin use in these cases. METHODS: An analysis of all malpractice claims resulting in disciplinary action against physicians and midwives during the period 1996-2003. Investigations and decisions made by the Board of Medical Responsibility were reviewed with special focus on the use of oxytocin. RESULTS: Of 77 cases, 60 regarded patients in labour. In the majority, there had been a normal pregnancy and spontaneous start of labour (78%). At the beginning of labour, 87% showed a normal fetal heart rate (FHR) pattern, indicating fetal well-being. In 70%, there was adverse fetal outcome with brain damage or death. The most common reason for disciplinary action was improper interpretation of fetal monitor tracings and corresponding failure to recognise fetal distress (76%). Injudicious use of oxytocin was common (68.5%), and was the primary reason for disciplinary action in 33% of the cases. CONCLUSION: In a Swedish setting, a few common clinical problems pervade; interpretation of FHR patterns and the use of oxytocin account for the majority of rulings of negligence in malpractice cases regarding delivery. Analysis of the cases suggests that the adverse fetal outcomes could possibly have been prevented.

    Acidemia at birth in the vigorous infant as a trigger incident to assess intrapartum care with regard to CTG patterns2013In: The Journal of Maternal-Fetal & Neonatal Medicine, ISSN 1476-7058, E-ISSN 1476-4954, Vol. 26, no 11, p. 1094-1098Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate if acidemia in vigorous infants is a useful variable in the assessement of intrapartm care with regard to cardiotocographic (CTG) patterns during the second stage. Methods: Cases (n = 241) were infants with an umbilical artery pH<7.05, controls (n 482) were infants with pH >= 7.05. Apgar score was >= 7 at 5 min in both groups. CTGs during the last two hours of labor were assessed and neonatal outcomes compared. A sub-analysis of cases with metabolic acidemia: pH<7.00 and base deficit >= 12 mmol/L and acidemia: 7.00<pH<7.05 was performed. Results: 63% of cases had a pathological CTG versus 26% of controls (p<0.001). Patterns with severe variable decelerations had a significantly longer duration in cases. Metabolic acidemia was significantly associated with severe variable decelerations and decreased variability. Infants to cases were admitted to neonatal care in 19% versus 2% of controls (p<0.001). With metabolic acidemia, 32% were admitted. Conclusion: An umbilical artery pH<7.05 at birth of vigorous infants may be a useful variable for quality control of intrapartum management with regard to the assessment of second-stage CTGs. Differences in duration of pathological patterns indicate passiveness in acidemic cases.

    Neonatal encephalopathy and the association to asphyxia in labor2014In: American Journal of Obstetrics and Gynecology, ISSN 0002-9378, E-ISSN 1097-6868, Vol. 211, no 6, p. 667.e1-667.e8Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: In cases with moderate and severe neonatal encephalopathy, we aimed to determine the proportion that was attributable to asphyxia during labor and to investigate the association between cardiotocographic (CTG) patterns and neonatal outcome.

    STUDY DESIGN: In a study population of 71,189 births from 2 Swedish university hospitals, 80 cases of neonatal encephalopathy were identified. Cases were categorized by admission CTG patterns (normal or abnormal) and by the presence of asphyxia (cord pH, <7.00; base deficit, ≥12 mmol/L). Cases with normal admission CTG patterns and asphyxia at birth were considered to experience asphyxia related to labor. CTG patterns were assessed for the 2 hours preceding delivery.

    RESULTS: Admission CTG patterns were normal in 51 cases (64%) and abnormal in 29 cases (36%). The rate of cases attributable to asphyxia (ie, hypoxic ischemic encephalopathy) was 48 of 80 cases (60%), most of which evolved during labor (43/80 cases; 54%). Both severe neonatal encephalopathy and neonatal death were more frequent with an abnormal, rather than with a normal, admission CTG pattern (13 [45%] vs 11 [22%]; P = .03), and 6 [21%] vs 3 [6%]; P = .04), respectively. Comparison of cases with an abnormal and a normal admission CTG pattern also revealed more frequently observed decreased variability (12 [60%] and 8 [22%], respectively) and more late decelerations (8 [40%] and 1 [3%], respectively).

    CONCLUSION: Moderate and severe encephalopathy is attributable to asphyxia in 60% of cases, most of which evolve during labor. An abnormal admission CTG pattern indicates a poorer neonatal outcome and more often is associated with pathologic CTG patterns preceding delivery.

    Suboptimal care and metabolic acidemia is associated with neonatal encephalopathy but not with neonatal seizures alone: a population-based clinical audit2014In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 93, no 5, p. 477-482Article in journal (Refereed)
    Abstract [en]

    ObjectiveTo determine the incidence of moderate to severe neonatal encephalopathy (NE) and neonatal seizures without encephalopathy, and the association with metabolic acidemia. Secondly, to investigate the occurrence of suboptimal intrapartum care and its impact on neonatal outcome. DesignClinical audit. SettingTwo university hospitals in Sweden. PopulationNeonates 34weeks with moderate or severe NE and neonatal seizures alone, i.e. without encephalopathy, from a population of 71189 births, where umbilical blood gases were routinely analyzed. MethodsNeonates were categorized depending on the presence of metabolic acidemia at birth by umbilical artery pH<7.00, base deficit 12mmol/L. Records were audited for suboptimal care and a decision was made on whether management was assessed to have impacted neonatal outcome. Main outcome measuresEncephalopathy and seizures alone. ResultsWe identified 80 neonates with NE and 30 with seizures alone, of which 48 (60%) and none, respectively, had metabolic acidemia. Suboptimal care could be assessed in 77 and occurred in 28 (36%) NE cases and in one neonate with seizures alone (p<0.001). In 47 NE cases with metabolic acidemia, suboptimal care occurred in 22 (47%) vs. 6/30 (20%) without metabolic acidemia (p=0.02). Suboptimal care had an impact on outcome in 18/77 (23%) NE cases but in no cases with seizures alone. ConclusionSuboptimal care was commonly seen with NE, particularly in neonates with metabolic acidemia, and also affected neonatal outcome. No such associations were found in neonates with seizures alone.

    Obstetric emergencies as antecedents to neonatal hypoxic ischemic encephalopathy, does parity matter?2018In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 97, no 11, p. 1396-1404Article in journal (Refereed)
    Abstract [en]

    Introduction: Our aim was to investigate the risk of moderate to severe hypoxic ischemic encephalopathy (HIE) by obstetric emergencies, with focus on the distribution of obstetric emergencies by parity, taking the history of a previous cesarean into account.

    Material and methods: Population-based cohort study of 692 428 live births at >= 36 weeks of gestation in Sweden, 2009-2015. Data were retrieved by linking the Swedish Medical Birth Register with the Swedish Neonatal Quality Register. Therapeutic hypothermia served as surrogate for moderate to severe HIE. Logistic regression analysis was used to estimate associations between HIE and placental abruption, eclampsia, cord prolapse, uterine rupture, and shoulder dystocia, presented as adjusted odds ratios (aORs) with 95% CI.

    Results: An obstetric emergency occurred in 133/464 (29%) of all HIE cases, more commonly in the parous (overall 37%; 48% with and 31% without a previous cesarean) than in the nulliparous (21%). Among nulliparas, shoulder dystocia was the most common obstetric emergency with the strongest association with HIE (aOR 48.2; 95% CI 28.2-82.6). In parous women without a previous cesarean, shoulder dystocia was most common, but placental abruption had the strongest association with HIE. Among parous women with a previous cesarean, uterine rupture was the most prevalent obstetric emergency with the strongest association with HIE (aOR 45.6; 95% CI 24.5-84.6).

    Conclusions: Obstetric emergencies are common among cases of moderate to severe HIE. The strong association with shoulder dystocia in nullipara, and with uterine rupture in women with previous cesarean deliveries, implies an opportunity for reducing the incidence of HIE.

    Evaluation of the discrepancy between pH and lactate in combined fetal scalp blood sampling2011In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 90, no 10, p. 1088-1093Article in journal (Refereed)
    Abstract [en]

    Objective. To evaluate the rate of discrepancy between pH and lactate values in fetal blood sampling (FBS). To evaluate differences in obstetric management in response to combined tests (pH and lactate) and single tests (pH or lactate).

    Design. Descriptive study.

    Setting. Uppsala University Hospital, Sweden. Population. Labors monitored by FBS during one year (n=241).

    Methods. Discrepancy in the combined tests was defined as a test having one abnormal and one normal value. Abnormal pH was defined as 7.24 or lower and abnormal lactate as 4.2 or higher. The results were categorized according to whether the test was normal or abnormal and according to whether it was a combined or single analysis. Main outcome measures. Discrepancy between pH and lactate values in combined tests. Frequency of operative delivery for fetal distress (ODFD). Time interval from the last FBS to ODFD.

    Results. In the combined tests with abnormality, a discrepancy between pH and lactate values occurred in 55%. The mean time interval from the last FBS to ODFD was longer in combined tests with one abnormal compared with two abnormal test results, 75 vs. 37 minutes (p<0.05). Operative delivery for fetal distress was performed less often after combined tests than after single tests: 41/62 (66%) vs. 19/20 (95%) (p<0.05).

    Conclusion. In the combined test, discrepancies were common and occurred in half of the samples with an abnormality. Obstetric management was influenced by the discrepancy between test results with respect to ODFD rates and the time interval from the last FBS to delivery.

    Experience of fetal scalp blood sampling during labor2014In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 93, no 1, p. 113-117Article in journal (Refereed)
    Abstract [en]

    Fetal scalp blood sampling (FBS) is often claimed to be painful for women in labor and difficult for obstetricians to perform. Our aim was to assess women's experience of pain during FBS and obstetricians' experience of difficulty in performing the test. At a tertiary centre in Sweden, a questionnaire with answers on a ten-point scale was completed by 51 women and by the obstetricians performing the test. Women's experience of pain had a median of 3.5. FBS was well tolerated in women who had epidural analgesia, but might be associated with pain in women without. Higher maternal body mass index and less cervical dilatation were associated with higher pain ratings. Obstetricians did not generally experience scalp sampling as difficult to perform (median score 3.0). However, the sampling procedure can be more complicated in situations with higher maternal body mass, less cervical dilatation, and a higher station of the fetal head.

    Antepartum risk factors for moderate to severe neonatal hypoxic ischemic encephalopathy: a Swedish national cohort study2018In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 97, no 5, p. 615-623Article in journal (Refereed)
    Abstract [en]

    Introduction

    Our aim was to identify antepartum risk factors for neonatal hypoxic ischemic encephalopathy, with a focus on maternal body mass index and height.

    Material and methods

    National population-based cohort study of 692 428 live-born infants 36 gestational weeks in Sweden, 2009-2015. Data from the Swedish Medical Birth Register and the Swedish Neonatal Quality Register were linked. Short maternal stature was defined as 155 cm, and overweight as body mass index 25 kg/m(2). Therapeutic hypothermia served as surrogate marker of moderate to severe hypoxic ischemic encephalopathy. Associations between maternal and infant characteristics and hypoxic ischemic encephalopathy were calculated with logistic regression analyses, and risks were presented as odds ratios with 95% confidence intervals.

    Results

    Moderate to severe hypoxic ischemic encephalopathy occurred in 0.67/1000 infants. Nulliparity, previous cesarean delivery, short stature, overweight, gestational age, occiput posterior presentation and birthweight were all independently associated with hypoxic ischemic encephalopathy. The risk of hypoxic ischemic encephalopathy increased with decreasing maternal height and increasing body mass index. Compared with non-short women (156 cm) with normal weight (body mass index <25 kg/m(2)), those with both short stature and overweight had increased risk of hypoxic ischemic encephalopathy (odds ratio 3.66; 95% confidence intervals 2.41-5.55). Among parous women with both short stature and overweight, the risk was almost sixfold (odds ratio 5.74; 95% confidence intervals 3.41-9.66).

    Conclusions

    Antepartum risk factors for moderate to severe hypoxic ischemic encephalopathy included nulliparity, previous cesarean delivery, short stature, overweight, gestational age, occiput posterior presentation and birthweight. The combination of maternal short stature and overweight was associated with a more than threefold risk of subsequent hypoxic ischemic encephalopathy.

    Contraception use and unplanned pregnancies in a peri-urban area of eSwatini (Swaziland)2019In: Sexual & Reproductive HealthCare, ISSN 1877-5756, E-ISSN 1877-5764, Vol. 20, p. 1-6Article in journal (Refereed)
    Abstract [en]

    Background: Despite reported high levels of contraception use in eSwatini, unplanned pregnancies are common. The aims of this study were to investigate prevalence and determinants of contraception use and unplanned pregnancies in a disadvantaged area in the Kingdom of eSwatini (Swaziland), and to investigate the association between unplanned pregnancies and antenatal care attendance. Methods: This cross-sectional study was conducted at the non-governmental organization Siphilile Maternal and Child Health in Matsapha, a peri-urban industrial area, using data from pre-existing client records. The sample included clients (n = 1436) registered during pregnancy or up to three months postpartum between August 2014 and April 2016. Contraception use before conception and unplanned pregnancies were analysed with logistic regression to find associations with socio-demographic factors and health care utilization. Results: In this population, 59% (n = 737) stated to have used contraception before becoming pregnant. Teenagers and first-time mothers were less likely to have used contraception. Seventy percent (789/1124) of the pregnancies were unplanned. Older women ( 35 years) were less likely while teenagers and multiparas (>= 3 children) were more likely to have an unplanned pregnancy. Women with unplanned pregnancies were less likely to attend the recommended number of antenatal care visits compared to women with planned pregnancies. Conclusion: The rate of unplanned pregnancies is high in this population, especially among teenagers. Family planning interventions need to focus on preconception care for teenagers to enable pregnancy planning including improved antenatal care attendance.

    High-dose versus low-dose of oxytocin for labour augmentation: a randomised controlled trial2019In: Women and Birth, ISSN 1871-5192, E-ISSN 1878-1799, Vol. 32, no 4, p. 356-363Article in journal (Refereed)
    Abstract [en]

    Problem: Delayed labour progress is common in nulliparous women, often leading to caesarean section despite augmentation of labour with synthetic oxytocin.

    Background: High-or low-dose oxytocin can be used for augmentation of delayed labour, but evidence for promoting high-dose is weak.

    Aim: To ascertain the effect on caesarean section rate of high-dose versus low-dose oxytocin for augmentation of delayed labour in nulliparous women.

    Methods: Multicentre parallel double-blind randomised controlled trial (ClinicalTrials.gov: NCT01587625) in six labour wards in Sweden. Healthy nulliparous women at term with singleton cephalic fetal presentation, spontaneous labour onset, confirmed delay in labour and ruptured membranes (n = 1351) were randomised to labour augmentation with either high-dose (6.6 mU/minute) or low-dose (3.3 mU/minute) oxytocin infusion.

    Findings: 1295 women were included in intention-to-treat analysis (high-dose n = 647; low-dose n = 648). Caesarean section rates did not differ between groups (12.4% and 12.3%, 95% Confidence Interval -3.7 to 3.8). Women with high-dose oxytocin had: shorter labours (-23.4 min); more uterine tachysystole (43.2% versus 33.5%); similar rates of instrumental vaginal births, with more due to fetal distress (43.8% versus 22.7%) and fewer due to failure to progress (39.6% versus 58.8%). There were no differences in neonatal outcomes.

    Discussion: Our study could not confirm results of two systematic reviews indicating, with weak evidence, that use of high-dose oxytocin was associated with lower frequency of caesarean section.

    Conclusion: We found no advantages for routine use of high-dose oxytocin in the management of delay in labour. Low-dose oxytocin regimen is recommended to avoid unnecessary events of tachysystole and fetal distress.

    A longitudinal, multi-centre, superiority, randomized controlled trial of internet-based cognitive behavioural therapy (iCBT) versus treatment-as-usual (TAU) for negative experiences and posttraumatic stress following childbirth: the JUNO study protocol2018In: BMC Pregnancy and Childbirth, ISSN 1471-2393, E-ISSN 1471-2393, Vol. 18, article id 387Article in journal (Refereed)
    Abstract [en]

    Background: About one-third of women report their childbirth as traumatic and up to 10% have severe traumatic stress responses to birth. The prevalence of Posttraumatic stress disorder following childbirth (PTSD FC) is estimated to 3%. Women with PTSD FC report the same symptoms as other patients with PTSD following other types of trauma. The effect of psychological treatment for women with PTSD FC has only been studied in a few trials. Similarly, studies on treatment needs for women not diagnosed as having PTSD FC but who nevertheless face psychological problems are lacking. Methods/design: Women who rate their overall birth experience as negative on a Likert scale, and/or had an immediate caesarean section and/or a major postpartum haemorrhage are randomized to either internet delivered cognitive behaviour therapy (iCBT) plus treatment as usual (TAU) or TAU. The iCBT is to be delivered in two steps. The first step consists of six weekly modules for both the woman and her partner (if they wish to participate) with minimal therapeutic support. Step 2 consists of eight weekly modules with extended therapeutic support and will be offered to participants whom after step 1 report PTSD FC. Assessments will be made at baseline, 6 weeks, 14 weeks, and at follow-ups at 1, 2, 3 and 4 years after baseline. The primary outcome measures are symptoms of posttraumatic stress and depression. Secondary outcomes are quality of life, parent-child bonding, marital satisfaction, coping strategies, experience regarding the quality of care received, health-related quality of life, number of re-visits to the clinic and number of appointments for counselling during the 4 years' period after the negative childbirth experience, time until the woman gets pregnant again, and the type of birth in the subsequent pregnancy. A health economic evaluation in the form of a cost utility analysis will be conducted. Discussion: This study protocol describes a randomized controlled trial that will provide information about the effectiveness of iCBT in women with negative experiences, posttraumatic stress, and PTSD FC.

    Correlates of postpartum depression in first time mothers without previous psychiatric contact2017In: European psychiatry, ISSN 0924-9338, E-ISSN 1778-3585, Vol. 40, p. 4-12Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Postpartum depression (PPD) is a common disorder after childbirth. The strongest known predictors are a history of depression and/or a history of PPD. However, for a significant proportion of women, PPD constitutes their first depressive episode. This study aimed to gain further insight into the risk factors for PPD in first time mothers without previous psychiatric contact.

    METHODS: Women delivering in Uppsala University Hospital, Sweden, from May 2006 to June 2007, were asked to participate and filled out questionnaires five days and six weeks postpartum, containing inter alia the Edinburgh Postnatal Depression Scale (EPDS). Univariate logistic regression models, as well as a path analysis, were performed to unveil the complex interplay between the study variables.

    RESULTS: Of the 653 participating primiparas, 10.3% and 6.4% reported depressive symptoms (EPDS≥12 points) five days and six weeks postpartum, respectively. In the path analysis, a positive association between anxiety proneness and depressive symptoms at five days and six weeks postpartum was identified. For depressive symptoms six weeks after delivery, additional risk factors were detected, namely depressive symptoms five days postpartum and subjective experience of problems with the baby. Caesarean section and assisted vaginal delivery were associated with fewer depressive symptoms at 6 six weeks postpartum.

    CONCLUSIONS: Identification of anxiety proneness, delivery mode and problems with the baby as risk factors for self-reported depressive symptoms postpartum in this group of primiparas can be important in helping health care professionals identify women at increased risk of affective disorders in the perinatal period, and provide a base for early intervention.

    Self-reported exposure to severe events on the labour ward among Swedish midwives and obstetricians: A cross-sectional retrospective study2017In: International Journal of Nursing Studies, ISSN 0020-7489, E-ISSN 1873-491X, Vol. 65, p. 8-16Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The process of delivery entails potentially traumatic events in which the mother or child becomes injured or dies. Midwives and obstetricians are sometimes responsible for these events and can be negatively affected by them as well as by the resulting investigation or complaints procedure (clinical negligence).

    OBJECTIVE: To assess the self-reported exposure rate of severe events among midwives and obstetricians on the delivery ward and the cumulative risk by professional years and subsequent investigations and complaints.

    DESIGN: Cross-sectional survey.

    PARTICIPANTS: Members of the Swedish Association of Midwives (SFB) and the Swedish Society of Obstetrics and Gynaecology (SFOG).

    METHODS: A questionnaire covering demographic characteristics, experiences of self-reported severe events on the delivery ward, and complaints of medical negligence was developed. Potential consequences of the complaint was not reported. A severe event was defined as: 1) the death of an infant due to delivery-related causes during childbirth or while on the neonatal ward; 2) an infant being severely asphyxiated or injured at delivery; 3) maternal death; 4) very severe or life threatening maternal morbidity; or 5) other stressful events during delivery, such as exposure to violence or aggression.

    RESULTS: The response rate was 39.9% (n=1459) for midwives and 47.1% (n=706) for obstetricians. Eighty-four percent of the obstetricians and almost 71% of responding midwives had experienced one or more self-reported severe obstetric event with detrimental consequences for the woman or the new-born. Fourteen percent of the midwives and 22.4% of the obstetricians had faced complaints of medical negligence from the patient or the family of the patient.

    CONCLUSIONS: A considerable proportion of midwives and obstetricians will, in the course of their working life, experience severe obstetric events in which the mother or the new-born is injured or dies. Preparedness for such exposure should be part of the training, as should managerial and peer support for those in need. This could prevent serious consequences for the health care professionals involved and their subsequent careers.

    Post-traumatic stress symptoms in Swedish obstetricians and midwives after severe obstetric events: a cross-sectional retrospective survey2017In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 124, no 8, p. 1264-1271Article in journal (Refereed)
    Abstract [en]

    Objective: To examine post-traumatic stress reactions among obstetricians and midwives, experiences of support and professional consequences after severe events in the labour ward.

    Design: Cross-sectional online survey from January 7 to March 10, 2014.

    Population: Members of the Swedish Society of Obstetrics and Gynaecology and the Swedish Association of Midwives.

    Methods: Potentially traumatic events were defined as: the child died or was severely injured during delivery; maternal near-miss; maternal mortality; and other events such as violence or threat. The validated Screen Questionnaire Posttraumatic Stress Disorder (SQ-PTSD), based on DSM-IV (1994) 4th edition, was used to assess partial post-traumatic stress disorder (PTSD) and probable PTSD.

    Main outcome measures: Partial or probable PTSD.

    Results: The response rate was 47% for obstetricians (n = 706) and 40% (n = 1459) for midwives. Eighty-four percent of the obstetricians and 71% of the midwives reported experiencing at least one severe event on the delivery ward. Fifteen percent of both professions reported symptoms indicative of partial PTSD, whereas 7% of the obstetricians and 5% of the midwives indicated symptoms fulfilling PTSD criteria. Having experienced emotions of guilt or perceived insufficient support from friends predicted a higher risk of suffering from partial or probable PTSD. Obstetricians and midwives with partial PTSD symptoms chose to change their work to outpatient care significantly more often than colleagues without these symptoms.

    Conclusions: A substantial proportion of obstetricians and midwives reported symptoms of partial or probable PTSD after severe traumatic events experienced on the labour ward. Support and resilience training could avoid suffering and consequences for professional carers.
