Abstract [en]

Background: Two randomised controlled trials (RCTs) of decompressive craniectomy (DC) in traumatic brain injury (TBI) have shown poor outcome, but there are considerations of how these protocols relate to real practice. The aims of this study were to evaluate usage and outcome of DC and thiopental in a single centre.

Method: The study included all TBI patients treated at the neurointensive care unit, Akademiska sjukhuset, Uppsala, Sweden, between 2008 and 2014. Of 609 patients aged 16 years or older, 35 treated with DC and 23 treated with thiopental only were studied in particular. Background variables, intracranial pressure (ICP) measures and global outcome were analysed.

Results: Of 35 DC patients, 9 were treated stepwise with thiopental before DC, 9 were treated stepwise with no thiopental before DC and 17 were treated primarily with DC. Six patients received thiopental after DC. For 23 patients, no DC was needed after thiopental. Eighty-eight percent of our DC patients would have qualified for the DECRA study and 38% for the Rescue-ICP trial. Favourable outcome was 44% in patients treated with thiopental before DC, 56% in patients treated with DC without prior thiopental, 29% in patients treated primarily with DC and 52% in patients treated with thiopental with no DC.

Conclusions: The place for DC in TBI management must be evaluated better, and we believe it is important that future RCTs should have clearer and less permissive ICP criteria regarding when thiopental should be followed by DC and DC followed by thiopental.

Abstract [en]

The increasing number of elderly patients with traumatic brain injury (TBI) leads to specific neurointensive care (NIC) challenges. Therefore, elderly subjects with TBI need to be further studied. In this study we evaluated the demographics, management and outcome of elderly TBI patients receiving modern NIC. Patients referred to our NIC unit between 2008 and 2010 were included. Patients were divided in two age groups, elderly (E) a parts per thousand yen65 years and younger (Y) 64-15 years. Parameters studied were the dominant finding on CT scans, neurological motor skills and consciousness, type of monitoring, neurosurgical procedures/treatments and Glasgow Outcome Scale Extended score at 6 months after injury. Sixty-two E (22 %) and 222 Y (78 %) patients were included. Falls were more common in E (81 %) and vehicle accidents were more common in Y patients (37 %). Acute subdural hematoma was significantly more common in E (50 % of cases) compared to Y patients (18 %). Intracranial pressure was monitored in 44 % of E and 57 % of Y patients. Evacuation of significant mass lesions was performed more common in the E group. The NIC mortality was similar in both groups (4-6 %). Favorable outcome was observed in 72 % of Y and 51 % of E patients. At the time of follow-up 25 % of E and 7 % of Y patients had died. The outcome of elderly patients with TBI was significantly worse than in younger patients, as expected. However, as much as 51 % of the elderly patients showed a favorable outcome after NIC. We believe that these results encourage modern NIC in elderly patients with TBI. We need to study how secondary brain injury mechanisms differ in the older patients and to identify specific outcome predictors for elderly patients with TBI.

Abstract [en]

Periodic evaluation of neurointensive care (NIC) is important. There is a risk that quality of daily care declines and there may also be unrecognized changes in patient characteristics and management. The aim of this work was to investigate the characteristics and outcome for traumatic brain injury (TBI) patients in the period 2008-2009 in comparison with 1996-1997 and to some extent also with earlier periods. TBI patients 16-79 years old admitted from 2008 to 2009 were selected for the study. Glasgow Coma Scale Motor score at admission (GCS M), radiology, surgery, and outcome (Glasgow Outcome Extended Scale) were collected from Uppsala Traumatic Brain Injury Register. The study included 148 patients (mean age, 45 years). Patients > 60 years old increased from 16 % 1996-1997 to 30 % 2008-2009 (p < 0.01). The proportion of GCS M 4-6 were similar, 92 vs. 93 % (NS). In 1996-1997 patients, 73 % had diffuse injury (Marshall classification) compared to 77 % for the 2008-2009 period (NS). More patients underwent surgery during 2008-2009 (43 %) compared to 1996-1997 (32 %, p < 0.05). Good recovery increased and mortality decreased substantially from 1980-1981 to 1987-1988 and to 1996-1997, but then the results were unchanged in the 2008-2009 period, with 73 % favorable outcome and 11 % mortality. Mortality increased in GCS M 6-4, from 2.8 % in 1996-1997 to 10 % in 2008-2009 (p < 0.05); most of the patients that died had aggravating factors, e.g., high age, malignancy. A large-proportion favorable outcome was maintained despite that patients > 60 years with poorer prognosis doubled, indicating that the quality of NIC has increased or at least is unchanged. More surgery may have contributed to maintaining the large proportion of favorable outcome. For future improvements, more knowledge about TBI management in the elderly is required.
