Despite pediatric guidelines, variability exists in the management of severe traumatic brain injury (TBI), as somewhere between 7 and 60% of children undergo intracranial pressure (ICP) monitoring. Reasons for this low adherence to TBI management guidelines remain unclear. The objective of this study was to evaluate the current practices at CHU Sainte-Justine with regards to ICP monitoring in severe TBI and explore the reasons why ICP monitoring is not undertaken. ⋯ Our study confirms that many children with severe TBI do not undergo ICP monitoring, mainly due to rapid improvement or moribund status. A subgroup of patients, with reassuring cerebral CT scan, was not monitored. Further research is necessary to assess if imaging should be considered in ICP indication, as in adult guidelines.

Review Meta AnalysisCerebral vasospasm after traumatic brain injury: an update.
Post-traumatic vasospasm (PTV) remains a poorly understood entity. Using a systematic review approach, we examined the incidence, mechanisms, risk factors, impact on outcome and potential therapies of PTV. ⋯ Mechanical stretching, inflammation, calcium dysregulation, endotelin, contractile proteins, products of cerebral metabolism and cortical spreading depolarization have been involved in PTV pathophysiology. PTV occurs in up to 30-40% of the patients after severe traumatic brain injury. Usually, PTV starts within the first 3 days following head trauma and may last 5 to 10 days. Young age, low Glasgow Coma Score at admission and subarachnoid hemorrhage have been identified as risk factors of PTV. Suspected on transcranial Doppler, PTV diagnosis is best confirmed by angiography, CT angiography or MR angiography, and perfusion and ischaemic consequences by perfusion CT or MRI. Early PTV is associated with poor outcome. No PTV prevention strategy has proved efficient up to now. Regarding PTV treatment, only nimodipine and intra-arterial papaverine have been studied up to now. Treatment with milrinone has been described in a few cases reports and may represent a new therapeutic option.

Review Meta Analysis Comparative StudyComparisons between small intestinal and gastric feeding in severe traumatic brain injury: a systematic review and meta-analysis of randomized controlled trials.
Nutritional support is highly recommended for reducing the risk of nosocomial infections, such as pneumonitis, in patients with severe traumatic brain injury (TBI). Currently, there is no consensus for the preferred route of feeding. The authors compared the risks of pneumonitis and other important outcomes associated with small intestinal and gastric feeding in patients with severe TBI. ⋯ The limited evidence suggests that small bowel feeding in patients with severe TBI is associated with a risk of pneumonia that is lower than that with gastric feeding. From this result, the authors recommend the use of small intestinal feeding to reduce the incidence of pneumonitis in patients with severe TBI.

Case ReportsMassive cerebral swelling immediately after cranioplasty, a fatal and unpredictable complication: report of 4 cases.
Cranioplasty after decompressive craniectomy (DC) is associated with increased morbidity, but the reported mortality rate is low. Recently, some authors have reported a rare unexplained complication of sudden death in association with massive cerebral edema immediately after cranioplasty. The author reports on 4 patients who underwent cranioplasty after DC between January 2005 and August 2010 at his department and died because of massive cerebral edema immediately after uneventful surgery and anesthesia. ⋯ A MEDLINE search showed 8 similar cases that were reported previously. Fatal cerebral swelling after uneventful cranioplasty is a distinct clinical entity, although it is unpredictable. It is postulated that a negative pressure difference from the elimination of atmospheric pressure that had been chronically applied on the injured sinking brain in combination with the negative pressure applied by the closed subgaleal suction drain may lead to a massive brain shift toward the cranioplasty site and initiate a fatal vasomotor reaction.

Outcome of children with severe traumatic brain injury who are treated with decompressive craniectomy.
OBJECT Decompressive craniectomy (DC) for the management of severe traumatic brain injury (TBI) is controversial. The authors sought to determine if DC improves the outcome of children with severe TBI. METHODS In a retrospective, case-control study, medical records of all patients admitted to the pediatric ICU between May 1998 and May 2008 with severe TBI and treated with DC were identified and matched to patients who were treated medically without DC. ⋯ However, among survivors, at 4 years (IQR 1-6 years) after the TBI, 42% (5/12) of the DC patients had mild disability or a Glasgow Outcome Scale score of 5 vs none (0/14) of the controls (p = 0.012). CONCLUSIONS In this retrospective, small case-control study, the authors have shown that early DC in pediatric patients with severe TBI improves outcome in survivors. Future prospective randomized controlled studies are needed to confirm these findings.
