Randomized Controlled Trial Multicenter StudyA Multicenter Evaluation of a Closed-Loop Anesthesia Delivery System: A Randomized Controlled Trial.
Closed-loop systems for anesthesia delivery have been shown to outperform traditional manual control in different clinical settings. The present trial was aimed at evaluating the feasibility and efficacy of Bispectral Index (BIS)-guided closed-loop anesthesia delivery system (CLADS) in comparison with manual control across multiple centers in India. ⋯ Our study in a multicenter setting proves the consistently better performance of automated anesthesia drug delivery compared with conventional manual control. This highlights an important advantage of an automated system for delivering standardized anesthesia, thereby overcoming differences in practices among anesthesiologists.

Comparative StudyTrends of Hemoglobin Oximetry: Do They Help Predict Blood Transfusion During Trauma Patient Resuscitation?
A noninvasive decision support tool for emergency transfusion would benefit triage and resuscitation. We tested whether 15 minutes of continuous pulse oximetry-derived hemoglobin measurements (SpHb) predict emergency blood transfusion better than conventional oximetry, vital signs, and invasive point-of-admission (POA) laboratory testing. We hypothesized that the trends in noninvasive SpHb features monitored for 15 minutes predict emergency transfusion better than pulse oximetry, shock index (SI = heart rate/systolic blood pressure), or routine POA laboratory measures. ⋯ SpHb added no benefit over conventional oximetry to predict urgent pRBC transfusion for trauma patients. Both models containing POA laboratory test features performed better at predicting pRBC use than prehospital SI, the current best noninvasive vital signs transfusion predictor.

ReviewPerioperative Complications in Obstructive Sleep Apnea Patients Undergoing Surgery: A Review of the Legal Literature.
Obstructive sleep apnea (OSA) is common in patients undergoing surgery. OSA, known or suspected, has been associated with significant perioperative adverse events, including severe neurologic injury and death. This study was undertaken to assess the legal consequences associated with poor outcomes related to OSA in the perioperative setting. ⋯ Perioperative complications related to OSA are increasingly being reported as the central contention of malpractice suits. These cases can be associated with severe financial penalties. These data likely underestimate the actual medicolegal burden, given that most such cases are settled out of court and are not accounted for in the legal literature.

Randomized Controlled TrialPerioperative Duloxetine to Improve Postoperative Recovery After Abdominal Hysterectomy: A Prospective, Randomized, Double-Blinded, Placebo-Controlled Study.
Postsurgical quality of recovery is worse in female than that in male patients. Duloxetine has been used successfully for the treatment of chronic pain conditions, but its use for preventing acute postoperative pain has been limited to a single previous study. More importantly, the effect of preoperative duloxetine on global postoperative quality of recovery has yet to be evaluated. The main objective of the current investigation was to evaluate the effect of perioperative duloxetine on postoperative quality of recovery in women undergoing abdominal hysterectomy. ⋯ Duloxetine improves postoperative quality of recovery after abdominal hysterectomy. In addition, duloxetine reduces postoperative opioid consumption, even in the presence of a robust multimodal analgesic strategy. Duloxetine seems to be a viable pharmacologic strategy to improve postoperative quality of recovery in female patients undergoing abdominal hysterectomy.
