STUDY OBJECTIVE To determine whether the administration of remifentanil increases the incidence of postoperative shivering in comparison with the administration of alfentanil, fentanyl, or sufentanil. DESIGN Meta-analysis. SETTING Operating room and postanesthesia care unit. MEASUREMENTS We performed a computerized search of articles on PubMed, MEDLINE, and Scopus. Meta-analysis was performed using Review Manager and the DerSimonian and Laird random-effects model. The pooled effect estimates for binary variables were calculated as relative risk (RR) values with 95% confidence intervals (CIs). MAIN RESULTS Eighteen randomized controlled trials met our inclusion criteria. Remifentanil was associated with a significantly increased incidence of postoperative shivering compared with other opioids (RR=2.17; CI, 1.76-2.68; P<.00001; I(2)=0.00%). A subgroup analysis of remifentanil compared with alfentanil, fentanyl, or sufentanil showed that only sufentanil had a similar rate of postoperative shivering incidence (RR=2.13; CI, 0.67-6.74; P=.20; I(2)=0.00%). Remifentanil administration was associated with a significant increase in the incidence of postoperative shivering compared with the administration of other opioids when both propofol (RR=2.44; CI, 1.52-3.92; P=.0002; I(2)=0.00%) and inhalation anesthesia drugs (RR=2.45; CI, 1.46-4.11; P=.0007; I(2)=0.00%) were used for anesthesia maintenance. In addition, the administration of remifentanil at both low (RR=2.06; CI, 1.63-2.60; P<.00001; I(2)=0.00%) and high dosages (RR=2.77; CI, 1.67-4.57; P<.0001; I(2)=0.00%) was associated with a significant increase in the incidence of postoperative shivering compared with the administration of other opioids. CONCLUSIONS Our meta-analysis showed that remifentanil was associated with an increased incidence of postoperative shivering compared with alfentanil or fentanyl, but no significant difference was seen when compared with sufentanil.

STUDY OBJECTIVE Videolaryngoscopy has become more common since the 2000s. Despite several anecdotal reports in the literature, it remains unclear whether videolaryngoscopy is superior to direct Macintosh laryngoscopy for tracheal intubation in adults with obesity. This systematic review and meta-analysis focused on prospective randomised trials comparing videolaryngoscopes with the Macintosh laryngoscope for tracheal intubation in adults with obesity. DESIGN Systematic review, Meta-analysis SETTING: Operating room, Obesity patients MEASUREMENTS: Data on success rate, intubation time, and glottic visualisation during tracheal intubation were extracted from the identified studies. In a subgroup analysis, we also compared the parameters for videolaryngoscopes with a tracheal tube guide channel and those without a tracheal tube guide channel. Data from individual trials were combined, and the DerSimonian and Laird random-effect model was used to calculate either the pooled relative risk (RR) or the weighted mean difference (WMD) as well as the corresponding 95% confidence intervals (CI). MAIN RESULTS Eleven articles describing 13 trials met the inclusion criteria. The performance of videolaryngoscopes was superior to that of the Macintosh laryngoscope for all outcomes. (Success rate; RR=1.11, 95% CI 1.04 to 1.18, p=0.001, I2=63%, Intubation time; WMD=-16.1, 95% CI -31.1 to -1.10, p=0.04, I2=97%, Glottic visualisation; RR=1.19, 95% CI 1.09 to 1.30, p<0.0001, I2=76%) In the subgroup analysis, the performance of both types of videolaryngoscopes (with and without a tracheal tube guide channel) was superior to that of the Macintosh laryngoscope, except for intubation time with the videolaryngoscopes without a tracheal tube guide channel. CONCLUSIONS Videolaryngoscopes were superior to the Macintosh laryngoscope for tracheal intubation in adults with obesity. (GRADE score: low or very low.).

STUDY OBJECTIVE To investigate whether Airtraq® attenuate the hemodynamic responses to tracheal intubation using single-lumen tubes in adults as compared with the Macintosh laryngoscope. DESIGN Meta-analysis. SETTING Operating room. MEASUREMENTS The primary outcome of this meta-analysis was to determine whether laryngoscopy using the Airtraq® reduced hemodynamic responses-heart rate (HR) and mean blood pressure (MBP)-at 60 s (s) after tracheal intubation compared to laryngoscopy with the Macintosh laryngoscope. Pooled differences in these hemodynamic responses between the two devices were expressed as weighted mean difference with 95% confidence intervals. We then conducted trial sequential analysis (TSA). The secondary outcome was to investigate whether the Airtraq® reduce the hemodynamic response at 120 s, 180 s, and 300 s after tracheal intubation compared to the Macintosh laryngoscope. We also conducted sensitivity analysis of the hemodynamic responses to tracheal intubation with the laryngoscopes using a multivariate random effects model accounting for within-study correlation of the longitudinal data. MAIN RESULTS From electronic databases, we selected 11 randomized controlled trials for studies that enrolled subjects satisfying our inclusion criteria. Compared with the Macintosh laryngoscope, the Airtraq® significantly reduced both HR and MBP at 60 s after tracheal intubation. In secondary outcome, the Airtraq® significantly reduced both HR and MBP at all measurement points, excluding HR at 300 s after tracheal intubation. TSA showed that total sample size reached the required information size for both HR and MBP. The sensitivity analysis revealed that the Airtraq® reduced both HR and MBP at all measurement points, excluding HR at 300 s after tracheal intubation. CONCLUSIONS The Airtraq® attenuates the hemodynamic response at 60 s after tracheal intubation compared with the Macintosh laryngoscope. (GRADE: Low) These results were supported by the sensitivity analysis. TSA suggested that the total sample size was exceeded TSA monitoring boundary both HR and MBP.

STUDY OBJECTIVE The C-MAC laryngoscope (C-MAC) is a videolaryngoscope that uses a modified Macintosh blade. Although several anecdotal reports exist, it remains unclear whether the C-MAC is superior to the Macintosh laryngoscope for tracheal intubation in the adult population. DESIGN Systematic review, meta-analysis. SETTING Operating room, intensive care unit. MEASUREMENTS For inclusion in our analysis, studies had to be prospective randomised trials which compared the C-MAC with the Macintosh laryngoscope for tracheal intubation in the adult population. Data on success rates, intubation time, glottic visualisation and incidence of external laryngeal manipulations (ELM) during tracheal intubation were extracted from the identified studies. In subgroup analysis, we separated those parameters to assess the influence of the airway condition (normal or difficult) and laryngoscopists (novice or experienced). We conducted a trial sequential analysis (TSA). MAIN RESULTS Sixteen articles with 18 trials met the inclusion criteria. The C-MAC provided better glottic visualisation compared to the Macintosh (RR, 1.08; 95% CI, 1.03-1.14). TSA corrected the CI to 1.01-1.19; thus, total sample size reached the required information size (RIS). Success rates and intubation time did not differ significantly between the laryngoscopes. TSA showed that total sample size reached the RIS for success rates. The TSA Z curve surpassed the futility boundary. The C-MAC required less ELM compared to the Macintosh (RR, 0.83; 95% CI, 0.72-0.96). TSA corrected the CI to 0.67-1.03; 52.3% of the RIS was achieved. In difficult airways, the C-MAC showed superior success rates, glottic visualisation, and less ELM compared to the Macintosh. Among experienced laryngoscopists, the C-MAC offered better glottic visualisation with less ELM than the Macintosh. CONCLUSIONS The C-MAC provided better glottic visualisation and less ELM (GRADE: Very Low or Moderate), with improved success rates, glottic visualisation, and less ELM in difficult airways.

STUDY OBJECTIVE To evaluate the efficacy of intravenous nitroglycerin (TNG) in preventing intraoperative myocardial ischemia (MI) under general anesthesia. Moreover, we analyzed the hemodynamic changes in heart rate (HR), mean blood pressure (MBP), and pulmonary capillary wedge pressure (PCWP) associated with TNG administration both before and after the induction of anesthesia. DESIGN Meta-analysis. SETTING Operating room, cardiac surgery or non-cardiac surgery, all surgeries were elective measurements. We performed a computerized search of articles on PubMed, Scopus, and the Cochrane Central Register of Controlled Trials. Meta-analysis was performed using Review Manager. The data from the individual trials were combined using a random-effects model to calculate either the pooled relative risk (RR) or the weighted mean difference (WMD) with 95% confidence interval (CI). We conducted trial sequential analysis (TSA). The primary outcome was the incidence of MI and the secondary outcomes were hemodynamic changes (HR, MBP, and PCWP). MAIN RESULTS Using electronic databases, we selected 10 trials with a total of 353 patients for our review. Prophylactic intravenous TNG did not significantly decrease the incidence of MI (RR=0.61; CI, 0.33 to 1.13; P=0.12; I2=55). TSA corrected the CI to 0.05 to 7.39 and showed that 9.5% of the required information size was achieved. In terms of hemodynamic changes, intravenous TNG significantly reduced MBP in comparison with the placebo (MBP pre-induction: WMD=-7.27; 95% CI -14.2 to -0.33; P=0.04; I2=97%; MBP post-induction: WMD=-5.13; 95% CI -9.17 to -1.09; P=0.01; I2=73%). CONCLUSIONS Our analyses showed that prophylactic intravenous TNG does not reduce the incidence of intraoperative MI. Moreover, TSA suggests that further studies are necessary to confirm the results (GRADE: very low). Prophylactic doses of intravenous TNG significantly reduced the MBP both pre and post anesthesia induction (GRADE: very low).
