Meta Analysis
Safety and efficacy of the oblique-axis plane in ultrasound-guided internal jugular vein puncture: A meta-analysis.
Objective This meta-analysis was performed to evaluate the safety and efficacy of the oblique-axis plane in ultrasound-guided internal jugular vein puncture. Methods We searched Embase, PubMed, the Cochrane Library, Web of Science, and China National Knowledge Infrastructure for relevant randomized clinical trials comparing the oblique axis with the short axis in ultrasound-guided internal jugular vein puncture. Results Five randomized clinical trials were included in this meta-analysis. ⋯ No significant difference was found in the first-pass success rate between the oblique-axis group and short-axis group. Additionally, there were no significant differences in the puncture success rate or number of attempts required between the two groups. Conclusion Ultrasound-guided internal jugular vein puncture using the oblique-axis plane reduced the risk of arterial puncture, but no difference was found in the first-pass success rate, puncture success rate, or number of attempts required.

Meta Analysis
Efficacy of ondansetron for spinal anesthesia during cesarean section: a meta-analysis of randomized trials.
Objective To investigate the efficacy and safety of ondansetron during cesarean section under spinal anesthesia. Methods We sought randomized controlled trials (RCTs) on ondansetron during spinal anesthesia for cesarean section in The Cochrane Library, PubMed, MEDLINE, and Web of Science from their inception to September 2016. ⋯ There were no significant differences in the incidences of pruritus, hypotension, or shivering during cesarean section under spinal anesthesia [RR = 0.92, 95% CI (0.83, 1.02); RR = 0.72 (0.50, 1.06), 95% CI (0.50, 1.06); and RR = 0.89, 95% CI (0.71, 1.11), respectively]. Conclusion Ondansetron effectively reduces the incidences of nausea/vomiting and bradycardia under spinal anesthesia during cesarean section.

Meta Analysis
Efficacy of parecoxib sodium on postoperative shivering: meta-analysis of clinical trials.
Objective To evaluate the effect of parecoxib on preventing postoperative shivering. Methods Main outcomes were the relative risk (odds ratio, OR) and 95% confidence interval (CI) relative to the incidence of shivering. Results Fourteen trials with 1,175 patients were analyzed. ⋯ Compared with placebo, there was no significant association of parecoxib sodium with restlessness [OR = 0.95, 95% CI (0.59, 1.52)] or nausea/vomiting [OR = 0.24, 95% CI (0.09, 0.66)]. In addition, pethidine rescue was used significantly more often in the control group than in the parecoxib sodium group [OR = 0.22, 95% CI (0.09, 0.53)]. Conclusions Parecoxib sodium may be an effective strategy for preventing postoperative shivering.

Meta Analysis
Effects of palonosetron and ondansetron on preventing nausea and vomiting after laparoscopic surgery.
Background This meta-analysis was performed to evaluate the efficacy and safety of palonosetron and ondansetron in preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic surgery with general anesthesia. Methods We searched for randomized controlled clinical trials in PubMed, Embase, and The Cochrane Library. Results Nine studies were enrolled in this meta-analysis and showed no statistically significant difference between palonosetron and ondansetron in the prevention of PONV in the first 24 hours after surgery (relative risk [RR], 0.62; 95% confidence interval [CI], 0.35-1.10). ⋯ No significant differences in side effects were found between palonosetron and ondansetron (RR, 0.67; 95% CI, 0.40-1.14). Conclusion This meta-analysis demonstrated that palonosetron is not more efficacious than ondansetron in the prevention of early PONV. However, palonosetron was more efficacious than ondansetron in the prevention of vomiting after laparoscopic surgery.

Objective The present study was performed to explore the therapeutic potential of simvastatin in subarachnoid hemorrhage (SAH) in the context of the Simvastatin in Aneurysmal Subarachnoid Hemorrhage (STASH) trial. Methods MEDLINE, EMBASE, and the Cochrane Library were searched for all randomized controlled trials (RCTs) investigating the therapeutic effect of simvastatin on aneurysmal SAH. We applied a random-effects model to calculate the data. ⋯ Sensitivity analysis showed that the STASH trial, which had a large population, did not influence the consolidated results of all three outcomes. Conclusions Simvastatin showed no benefits in decreasing the incidence of vasospasm, DCI, or all-cause mortality after aneurysmal SAH. We conclude that patients with SAH should not be treated routinely with simvastatin during the acute stage.
