Meta Analysis Comparative StudySecond-Generation Supraglottic Airway Devices Versus Endotracheal Intubation in Adults Undergoing Abdominopelvic Surgery: A Systematic Review and Meta-Analysis.
Second-generation supraglottic airway (SGA) devices are widely used, but thought to have inferior safety performance to endotracheal tubes (ETTs), but might be equally efficacious while improving patient-centered outcomes. We compared second-generation SGAs with ETTs for perioperative safety, efficacy, and quality of recovery in adults undergoing abdominopelvic surgery under general anesthesia. Our primary objective was to assess safety in the form of major airway complications. Secondary objectives were other safety, efficacy, and quality of recovery outcomes. ⋯ Second-generation SGAs reduce the risk of major airway complications compared with ETTs in adults undergoing abdominopelvic procedures under general anesthesia, with no reported clinically relevant differences in the risk of regurgitation or pulmonary aspiration. Additionally, they improve the quality of postoperative recovery with lower risk of sore throat, hoarseness, and postoperative nausea and vomiting. These data provide an opportunity for clinicians to reassess the implications of conservative airway management, and potentially expand the role of second-generation SGAs in routine clinical practice.

Objective : To evaluate if mechanical left ventricular unloading could reduce mortality in patients with cardiogenic shock undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO). Methods : We searched MEDLINE, Embase, and the Cochrane Library for randomized controlled trials and propensity score-matched studies published until December 20, 2023. The primary outcome was mortality at the longest follow-up. ⋯ Mechanical left ventricular unloading was significantly associated with reduced mortality at the longest follow-up (RR, 0.89; 95% CI, 0.84-0.94; P = 0.0001; moderate certainty of evidence), which was confirmed in studies using intra-aortic balloon pump. Benefits of mechanical unloading were also observed in terms of successful VA-ECMO weaning (RR, 1.15; 95% CI, 1.02-1.29; P = 0.02; low certainty of evidence) and favorable neurological outcome (two studies; RR, 2.45; 95% CI, 1.62-3.69; P < 0.0001; low certainty of evidence), although we observed an increased incidence of major bleeding (RR, 1.27; 95% CI, 1.02-1.59; P = 0.03; low certainty of evidence) and hemolysis (RR, 1.49; 95% CI, 1.10-2.02; P = 0.01; moderate certainty of evidence). Conclusions : Among adult patients with cardiogenic shock treated with VA-ECMO, mechanical left ventricular unloading was associated with reduced mortality, which was confirmed in studies using intra-aortic balloon pump as an unloading device.

Meta Analysis Comparative StudyComparison of Clinical Performance of I-gel and Fastrach Laryngeal Mask Airway as an Intubating Device in Adults: A Systematic Review and Meta-Analysis.
The supraglottic airway device (SGD) was introduced as a breakthrough in airway management. The Fastrach emerged as the first commercially available intubating SGD, drawing extensive investigation. I-gel is a more recent device that has gained popularity, can be used as an intubating SGD, and replaced Fastrach in many institutions. However, there is uncertainty regarding the comparison between these devices in terms of efficacy for intubation and ventilation, and safety in an airway rescue situation. ⋯ Based on our findings, a higher first-pass success rate was observed with the use of Fastrach when compared to I-gel. However, the use of I-gel might result in a better intubation success rate with the flexible scope-guided intubation. There are no significant differences in performance in terms of the success rate for intubation overall, time for device insertion, or time to intubation or complications regardless of the device used.

Electroencephalogram burst suppression can be associated with postoperative delirium; however, the results of relevant studies are discrepant. This systematic review and meta-analysis aimed to assess the association between intraoperative burst suppression and postoperative delirium in adult surgical patients. ⋯ The meta-analysis suggests an association between intraoperative burst suppression and postoperative delirium; however, the quality of evidence was very low. The limited number of studies and substantial heterogeneity across them emphasize the need for further high-quality studies to establish a more robust conclusion.
