Randomized Controlled Trial Comparative Study
Comparison of Ventilation With One-Handed Mask Seal With an Intraoral Mask Versus Conventional Cuffed Face Mask in a Cadaver Model: A Randomized Crossover Trial.
We compare received minute volume with an intraoral mask versus conventional cuffed face mask among medics obtaining a 1-handed mask seal on a cadaver model. ⋯ The intraoral mask resulted in greater received minute volume received compared with conventional cuffed face mask during ventilation with a 1-handed mask seal in a cadaver model. The intraoral mask may prove a useful airway adjunct for ventilation.

Paradoxical vocal fold motion disorder, also commonly termed vocal cord dysfunction, is a poorly understood cause of acute upper airway obstruction. Patients with paradoxical vocal fold motion frequently present to the emergency department (ED) with acute respiratory distress and stridor. ⋯ Although long-term management of paradoxical vocal fold motion is well described, there is a paucity of information about acute evaluation and management. This article aims to summarize the ED presentation and management of paradoxical vocal fold motion.

Making Sense of a Negative Clinical Trial Result: A Bayesian Analysis of a Clinical Trial of Lorazepam and Diazepam for Pediatric Status Epilepticus.
We demonstrate the application of a Bayesian approach to a recent negative clinical trial result. A Bayesian analysis of such a trial can provide a more useful interpretation of results and can incorporate previous evidence. ⋯ Because Bayesian analysis estimates the probability of one or more hypotheses, such an approach can provide more useful information about the meaning of the results of a negative trial outcome. In the case of pediatric status epilepticus, it is highly likely that lorazepam is noninferior and practically equivalent to diazepam.
