Observational Study
Emergency department monitor alarms rarely change clinical management: An observational study.
Monitor alarms are prevalent in the ED. Continuous electronic monitoring of patients' vital signs may alert staff to physiologic decompensation. However, repeated false alarms may lead to desensitization of staff to alarms. Mitigating this could involve prioritizing the most clinically-important alarms. There are, however, little data on which ED monitor alarms are clinical meaningful. We evaluated whether and which ED monitor alarms led to observable changes in patients' ED care. ⋯ Most ED monitor alarms did not observably affect patient care. Efforts at improving the clinical significance of alarms could focus on widening alarm thresholds, customizing alarms parameters for patients' clinical status, and on utilizing monitoring more selectively.

Patients who experience trauma, particularly thoracic trauma, may be at risk for missed cardiac injury. ⋯ We present a case of a 36-year-old male presenting to the Emergency Department (ED) as a trauma after a high-speed motor vehicle crash. After computed tomography (CT) scans revealed a right hemopneumothorax and multiple orthopedic injuries, the patient was admitted to the trauma neuroscience intensive care unit (TNICU), where telemetry revealed ST elevations. An electrocardiogram (EKG) was performed and he was noted to have an acute anterolateral STEMI. The patient was intubated and underwent a cardiac catheterization that revealed a dissection of his left anterior descending (LAD) coronary artery and a stent was successfully placed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In cases of trauma patients who can't report the symptoms they are experiencing, or have distracting injury, there is the potential for a missed diagnosis of either significant cardiac injury and/or myocardial infarction (MI). Emergency physicians should be aware that an EKG is recommended in the ED evaluation of a trauma patient, especially those with thoracic trauma.

Randomized Controlled Trial
Gentle facemask ventilation during induction of anesthesia.
To determine the level of inspiratory pressure minimizing the risk of gastric insufflation while providing adequate pulmonary ventilation. ⋯ Inspiratory pressure of 10 cm H2O allowed for reduced occurrence of gastric insufflation with proper lung ventilation during induction of anesthesia with sufentanil and propofol in nonparalyzed and nonobese patients.

Double sequential defibrillation (DSD) has been proposed as a viable treatment option for patients in refractory ventricular fibrillation/pulseless ventricular tachycardia (VF/pVT) out-of-hospital cardiac arrests (OHCA). However, currently there is insufficient evidence to support a widespread implementation of this therapy. ⋯ To date, it is difficult to conclude the real benefit of DSD for patients in refractory VF based on the available evidence. The findings of this scoping review suggest there is limited evidence to support at large-scale the use of DSD for refractory VF/pVT OHCA. Further research is needed to better characterize and understand the use of DSD for refractory VF/pVT, in order to implement best practices to maximize the effectiveness and efficiency of care.
