This review discusses the utility of risk scores, specifically, the role of preoperative risk scores in guiding the management of surgical patients, approaches to evaluate the quality of risk scores, and limitations to consider when applying risk scores in clinical practice. ⋯ Preoperative risk scores help inform perioperative clinical decision-making. Future research must determine how estimates of preoperative risk can be updated with information from the intraoperative period, how risk information should be communicated to patients, and which interventions can improve outcomes among patients within newly identified risk strata.

Quality of recovery is a complex construct whose definition is influenced heavily by the opinions and biases of the individual patient, clinician, or institution. Asa result, recovery assessment tools differ in their fundamental definitions of recovery, breadth, and assessment time frame. Accurate assessment of recovery is essential as suboptimal recovery has both economic and prognostic implications. ⋯ Ideally, recovery measures should assess outcomes in a simple dichotomous fashion and maintain relevancy by assessing in multiple domains at various time points. Assessment of recovery in a dichotomous fashion also has both clinical and research applications. It allows identification of suboptimal recovery at both individual and group levels,respectively, and when performed in real time, it allows the opportunity for timely targeted intervention specific to individual patients as well as for resource rationalization.

The purpose of this report is to facilitate an understanding of the possible application of xenon for neuroprotection in critical care settings. This narrative review appraises the literature assessing the efficacy and safety of xenon in preclinical models of acute ongoing neurologic injury. ⋯ According to the evidence to date, the neuroprotective efficacy of xenon in preclinical models and its safety in clinical anesthesia set the stage for the launch of randomized clinical trials to determine whether these encouraging neuroprotective findings can be translated into clinical utility.

The objectives for preparing this article were to review the historical context and epidemiology surrounding the North American prescription opioid crisis, to summarize the evidence regarding the benefits and harms of long-term opioid therapy for non-cancer pain, and to outline ways in which anesthesiologists may help ameliorate the problem. ⋯ Anesthesiologists are well positioned to take a leadership role in the management of postoperative discharge opioid therapy in an effort to curb the overutilization of opioids. Furthermore, anesthesiologists who regularly prescribe opioids for chronic pain patients should appreciate the limited evidence base for this practice and communicate the risks of opioid therapy to their patients.

Review Meta Analysis Comparative Study
Efficacy of palonosetron for preventing postoperative nausea and vomiting: a systematic review and meta-analysis.
Palonosetron, a second-generation 5-hydroxytryptamine 3 receptor antagonist (5-HT3RA), has unique characteristics relative to first-generation 5-HT3RAs such as ondansetron. Nevertheless, it remains unclear if palonosetron is better than ondansetron for the prevention of nausea and vomiting during the first 24 hr after surgery and is thus the focus of this systematic review. ⋯ Palonosetron provides more effective prophylaxis of early PON, late PON, and late POV compared with ondansetron. Future studies are required to investigate the role of palonosetron during 24-72 hr following surgery.
