Randomized Controlled TrialThe Effect of Deep Versus Moderate Neuromuscular Block on Surgical Conditions and Postoperative Respiratory Function in Bariatric Laparoscopic Surgery: A Randomized, Double Blind Clinical Trial.
In recent literature, it has been suggested that deep neuromuscular block (NMB) improves surgical conditions during laparoscopy; however, the evidence supporting this statement is limited, and this was not investigated in laparoscopic bariatric surgery. Moreover, residual NMB could impair postoperative respiratory function. We tested the hypotheses that deep NMB could improve the quality of surgical conditions for laparoscopic bariatric surgery compared with moderate NMB and investigated whether deep NMB puts patients at risk for postoperative respiratory impairment compared with moderate NMB. ⋯ Compared with a moderate NMB, there was insufficient evidence to conclude that deep NMB improves surgical conditions during laparoscopic bariatric surgery. Postoperative pulmonary function was substantially decreased after laparoscopic bariatric surgery independently of the NMB regime that was used. The study is limited by a small sample size.

Randomized Controlled Trial Comparative StudyGenerative Retrieval Improves Learning and Retention of Cardiac Anatomy Using Transesophageal Echocardiography.
Transesophageal echocardiography (TEE) is a valuable monitor for patients undergoing cardiac and noncardiac surgery as it allows for evaluation of cardiovascular compromise in the perioperative period. It is challenging for anesthesiology residents and medical students to learn to use and interpret TEE in the clinical environment. A critical component of learning to use and interpret TEE is a strong grasp of normal cardiovascular ultrasound anatomy. ⋯ Medical students and anesthesiology residents inexperienced in the use of TEE showed both improved learning and retention of basic cardiovascular ultrasound anatomy with the incorporation of GR into the educational experience.

ReviewSleep-Disordered Breathing, Postoperative Delirium, and Cognitive Impairment.
Sleep-disordered breathing (SDB) is highly prevalent in the general population and has been associated with cognitive impairment in older individuals. Delirium is an acute decline in cognitive function and attention that often occurs after surgery, especially in older individuals. Several recent studies suggest an association between SDB and postoperative delirium. ⋯ Health care professionals need to be aware that undiagnosed SDB may contribute to postoperative delirium. Preoperative screening for SDB and strategies to reduce the risk for postoperative delirium may be helpful in older individuals. Further studies are needed to clarify the relationship between SDB and postoperative delirium and elucidate the pathophysiology of postoperative delirium through SDB.
