Neurocritical care

Alcohol withdrawal syndrome (AWS) can range from mild jittery movements, nausea, sweating to more severe symptoms such as seizure and death. Severe AWS can worsen cognitive function, increase hospital length of stay, and in-hospital mortality and morbidity. ⋯ Treatment strategies such as symptom-based versus fixed dose benzodiazepine therapy and alternative agents such as baclofen, carbamazepine, dexmedetomidine, gabapentin, phenobarbital, ketamine, propofol, and valproic acid are also discussed. Finally, a treatment algorithm considering the neurocritical care patient is proposed to help guide therapy in this setting.

The use of cerebral autoregulation monitoring to identify patient-specific optimal mean arterial pressure (MAPOPT) has emerged as a technique to augment cerebral oxygen delivery in post-cardiac arrest patients. Our systematic review aims to determine (a) the average MAPOPT in these patients, (b) the feasibility of identifying MAPOPT, (c) the brain tissue oxygenation levels when MAP is within proximity to the MAPOPT and (d) the relationship between neurological outcome and MAPOPT-targeted resuscitation strategies. We carried out this review in accordance with the PRISMA guidelines. ⋯ There was no consistent association between targeting MAPOPT and improved neurological outcome. There is considerable heterogeneity in MAPOPT due to differences in monitoring methods of autoregulation. Further research is needed to assess the clinical utility of MAPOPT-guided strategies on decreasing secondary injury and improving neurological outcomes after ROSC.

Multicenter Study
Safety and Feasibility of a Novel Transnasal Cooling Device to Induce Normothermia in Febrile Cerebrovascular Patients.
Inducing normothermia with surface cooling temperature modulating devices (TMDs) is cumbersome and often associated with significant shivering. We tested the safety and feasibility of a novel transnasal evaporative cooling device to induce and maintain normothermia in febrile patients following ischemic and hemorrhagic stroke. ⋯ Inducing normothermia with a novel transnasal TMD appears to be safe, feasible and not associated with significant shivering. A multicenter trial testing the ability of the CoolStat to maintain normothermia for 24 h is currently underway.
