Randomized Controlled Trial
Effect of short versus long duration naps on blood pressure during simulated night shift work: A randomized crossover trial.
Blunting of the sleep-related dip in blood pressure (BP) has been linked to numerous cardiovascular outcomes including myocardial infarction. Blunting of BP dipping occurs during night shift work and previous research suggest that a 60-min or longer on-shift nap is needed to restore normal/healthy BP dipping. We sought to determine the effect of different durations of napping on BP during and following simulated night shifts. We hypothesized that the greatest benefit in terms of restoration of normal BP dipping during night shift work would be observed during a longer duration nap versus a shorter nap opportunity. ⋯ Restoration of a normal/healthy dip in BP is achievable during short and long duration nap opportunities during simulated night shift work. Our findings support the hypothesis that BP dipping is more common during longer 2-hr versus shorter 30-min naps.

The shame reaction is a highly negative emotional reaction shown to have long-term deleterious effects on the mental health of clinicians. Prior studies have focused on in-hospital personnel, but very little is known about what drives shame reactions in emergency medical services (EMS), a field with very high rates of post-traumatic stress disorder, burnout, anxiety, and depression. The objective of this study was to describe emotions, processes, and resilience associated with self-identified adverse events in the work of prehospital clinicians. ⋯ EMS clinicians often identify complex patient cases as those leading to emotions such as shame and guilt, with shame reactions being more common when a perceived error was committed. Coping mechanisms were varied, but individuals often relied on their coworkers in a sharing environment to adequately process their negative feelings, which was seen as a departure from past practices in EMS personnel. Our hope is that future studies will be able to use these findings to identify targets for intervention on negative mental health outcomes in EMS personnel.

Whether ambulance transport patterns are optimized to match children to high-readiness emergency departments (EDs) and the resulting effect on survival are unknown. We quantified the number of children transported by 9-1-1 emergency medical services (EMS) to high-readiness EDs, additional children within 30 minutes of a high-readiness ED, and the estimated effect on survival. ⋯ Approximately half of children transported by EMS were taken to high-readiness EDs and an additional one quarter could have been transported to such an ED, with measurable effect on survival.

Observational Study
Outcomes of Patients Receiving Thrombolysis in a Mobile Stroke Unit: a 4-Year Retrospective, Observational, Single-Center Study.
Patients with acute ischemic stroke (AIS) eligible for thrombolysis benefit when thrombolysis is administered quickly, and mobile stroke units (MSU) can facilitate timely thrombolysis. We sought to compare time metrics and clinical outcomes of AIS patients receiving thrombolysis in an MSU compared with patients arriving via local emergency medical services (EMS). ⋯ AIS patients received thrombolysis faster in the MSU compared with EMS and more frequently within 60 minutes of stroke onset. Point estimates for 90-day clinical outcomes of AIS patients treated with thrombolysis favored MSU without a statistically significant difference.

Randomized Controlled Trial
Supraglottic airway device to improve ventilation success and reduce pulmonary aspiration during cardio-pulmonary resuscitation by basic life support rescuers: a randomised cross-over human cadaver study.
Early airway management during cardiopulmonary resuscitation (CPR) prevents aspiration of gastric contents. Endotracheal intubation is the gold standard to protect airways, but supraglottic airway devices (SGA) may provide some protection with less training. Bag-mask ventilation (BMV) is the most common method used by rescuers. We hypothesized that SGA use by first rescuers during CPR could increase ventilation success rate and also decrease intragastric pressure and pulmonary aspiration. ⋯ Use of SGA by rescuers improved the ventilation success rate, decreased intragastric pressure, and did not affect key CPR metrics. SGA use by basic life support rescuers appears feasible and efficient.
