Authors: Rajnish K. Gupta, MD, and David A. Edwards, MD, PhD. In 2006 and 2011, the Anesthesia Patient Safety Foundation (APSF) convened multidisciplinary conferences to address the serious patient safety issue of Opioid-Induced Ventilatory Impairment (OIVI).1Given the significance of the problem, and that no best monitor exists for detection of OIVI associated-adverse events, the consensus […]

Background: Early postoperative ambulation is associated with enhanced functional recovery, particularly in the postpartum population, but ambulation questionnaires are limited by recall bias. This observational study aims to objectively quantify ambulation after neuraxial anesthesia and analgesia for cesarean delivery and vaginal delivery, respectively, by using […]

Background: This study tests the hypothesis that sevoflurane blocks long-term potentiation only if it is present during the high-frequency stimulation that induces long-term potentiation. Methods: Long-term potentiation, an electrophysiologic correlate of memory, was induced by high-frequency stimulation and measured as a persistent increase in the field excitatory […]

Background: Arterial oxygenation is often impaired during one-lung ventilation, due to both pulmonary shunt and atelectasis. The use of low tidal volume (VT) (5 ml/kg predicted body weight) in the context of a lung-protective approach exacerbates atelectasis. This study sought to determine the combined physiologic effects […]

Manufacturers developed algorithms to improve instrument performance during these challenges. There have been no independent comparisons of these devices. Methods: We evaluated the performance of four pulse oximeters (Masimo Radical-7, USA; Nihon Kohden OxyPal Neo, […]
