Review Meta Analysis
Benefits and safety of transdermal glyceryl trinitrate in acute stroke: a systematic review and meta-analysis of randomised trials.
Transdermal glyceryl trinitrate (GTN) has potential beneficial properties in acute stroke including intracerebral hemorrhage (ICH) and possible clinical benefits suggested in ultra-early stroke (≤6 h). Our meta-analysis updated the evidence on its safety and benefits in acute stroke. ⋯ Transdermal GTN reduces BP in acute stroke but does not alter clinical outcomes even in ultra-early stroke (≤6 h).

Critically ill children may require airway management to optimize delivery of oxygen and ventilation during resuscitation. We performed a systematic review of studies comparing the use of bag-valve-mask ventilation (BVM), supraglottic airway devices (SGA), and endotracheal intubation (ETI) in pediatric patients requiring prehospital airway management. ⋯ In this systematic review, studies of prehospital pediatric airway management varied in scope, design, and conclusions. There was insufficient evidence to evaluate efficacy of pediatric prehospital airway management; however, the current research suggests that there are equal or worse outcomes with the use of ETI compared to other airway techniques. Additional clinical trials are needed to assess the merits of this practice.

There is a lack of consensus regarding the role of investigations among patients presenting to the emergency department (ED) with recurrent seizures. The aim of this systematic review was to determine the frequency and utility of commonly requested investigations for nontrauma patients presenting to the ED with recurrent seizures. ⋯ In this population, CT brain scans appeared to be performed uncommonly but with moderate rates of abnormal findings. In the absence of prolonged alteration of consciousness, a history of brain tumor, or positive neurologic findings, however, neuroimaging was of low yield. Given the heterogeneity and potential limitations of these studies, further research on this topic is required.
