Randomized Controlled Trial
The effect of verbal and video feedback on learning direct laryngoscopy among novice laryngoscopists: a randomized pilot study.
Skill acquisition in direct laryngoscopy (DL) and tracheal intubation is complex. This pilot study aims to assess feasibility and determine sample size for a subsequent trial comparing DL instruction using a Macintosh-style video laryngoscope (MacVL), with and without video recordings, with conventional DL instruction. ⋯ This pilot study establishes feasibility and provides a sample size estimate for a future RCT. Required modifications to the study protocol include wider hospital involvement and consideration regarding standardization of airway education, teaching, feedback, and patient characteristics.

Feedback of performance data can improve professional practice and outcomes. Vital signs are not routinely used for quality improvement because of their limited access. Intraoperative hypothermia has been associated with deleterious effects, including surgical site infections and bleeding. We speculated that providing feedback could help keep temperature monitoring and management a priority in the anesthesiologist's mind, thereby improving perioperative temperature management. We hypothesized that feedback on thermoregulation metrics, without changes in policy, could reduce temperature-monitoring delays at the start of scoliosis correction surgery. ⋯ Feedback of intraoperative thermoregulation management improved both group and individual performances as measured by significant, sustained reductions in temperature-monitoring delays. Thus, intraoperative vital signs data may improve the quality of, and reduce the variability in, anesthetic practice.

This article describes the functioning of the international drug control system, its integration into national legislation and policy, and the collective impact on access to medicines. ⋯ Improving the capacity and quality of anesthesia care in low- and middle-income countries requires attention to improving access to controlled medicines. Anesthesiologists and others involved in global health work should collaborate with policymakers and others to improve national and international drug control legislation to ensure that attempts to thwart illicit drug trafficking and use do not compromise availability of controlled medicines.

The primary aim of this study was to evaluate the effect of acute administration of L-carnitine 100 mg·kg-1 iv on susceptibility to bupivacaine-induced cardiotoxicity in rats. ⋯ These findings suggest that acute administration of L-carnitine 100 mg·kg-1 decreases susceptibility to bupivacaine cardiotoxicity, but is ineffective during resuscitation from bupivacaine-induced cardiac arrest.
