Review Meta AnalysisXenon Anesthesia: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Xenon anesthesia has been studied for decades. However, no meta-analysis of randomized controlled trials (RCTs) on xenon anesthesia has been conducted. The aim of this study was to systematically review all available evidence from RCTs comparing xenon and other inhaled and IV anesthetics on anesthetic outcomes. Our meta-analysis attempted to quantify the effects of xenon anesthesia on clinical outcomes in relation to other anesthetics. ⋯ Xenon anesthesia provides relatively more stable intraoperative blood pressure, lower heart rate, and faster emergence from anesthesia than volatile and propofol anesthesia. However, xenon is associated with a higher incidence of PONV.

Review Meta AnalysisThe Effect of Intravenous Midazolam on Postoperative Nausea and Vomiting: A Meta-Analysis.
Research has shown that high-risk surgical patients benefit from a multimodal therapeutic approach to prevent postoperative nausea and vomiting (PONV). Our group sought to investigate the effect of administering IV midazolam on PONV. ⋯ Administration of preoperative or intraoperative IV midazolam is associated with a significant decrease in overall PONV, nausea, vomiting, and rescue antiemetic use. Providers may consider the administration of IV midazolam as part of a multimodal approach in preventing PONV.

Review Comparative StudyLimitations of Significance Testing in Clinical Research: A Review of Multiple Comparison Corrections and Effect Size Calculations with Correlated Measures.
Modern clinical research commonly uses complex designs with multiple related outcomes, including repeated-measures designs. While multiple comparison corrections and effect size calculations are needed to more accurately assess an intervention's significance and impact, understanding the limitations of these methods in the case of dependency and correlation is important. In this review, we outline methods for multiple comparison corrections and effect size calculations and considerations in cases of correlation and summarize relevant simulation studies to illustrate these concepts.

Randomized Controlled TrialSaline Flush After Rocuronium Bolus Reduces Onset Time and Prolongs Duration of Effect: A Randomized Clinical Trial.
Circulatory factors modify the onset time of neuromuscular-blocking drugs. Therefore, we hypothesized that infusion of a saline flush immediately after rocuronium administration would shorten the onset time without influencing the duration of the rocuronium effect. ⋯ Administering a 20-mL saline flush immediately after infusion of 0.6 mg/kg rocuronium in 10 mL normal saline shortened the onset time and prolonged the recovery phase of neuromuscular blockade.

Artifacts are frequently encountered during echocardiographic examinations. An understanding of the physics and underlying assumptions of ultrasound processing involved with image generation is important for accurate interpretation of 2D grayscale, spectral Doppler, color flow Doppler, and 3D artifacts and their clinical implications.
