  • Laryngeal Mask Airway versus Endotracheal Tubes for Airway Management during General Anesthesia in Children: A Meta-analysis

    Objective To assess the effectiveness and safety of laryngeal mask airway (LMA) and endotracheal tube (ETT) for airway management in pediatric general anesthesia. Methods Randomized controlled trials were collected through electronic searches of the PubMed, The Cochrane Library, EMbase, CBM, WanFang Data, VIP, CNKI from the date of establishment to November 2010. All the related data that matched the standards were abstracted by two reviewers independently. The quality of the included trials was evaluated according to the Cochrane Handbook 5.0. RevMan 5.0 software was used for meta-analysis of the complications, success of insertion on the first attempt and hemodynamic changes. Results A total of 39 trials involving 2 612 patients were included. The results of meta-analyses showed that LMA was superior to ETT in terms of less cough (RR=0.21, 95%CI 0.15 to 0.28, Plt;0.000 01), laryngospasm or bronchospasm (RR=0.37, 95%CI 0.18 to 0.77, P=0.008) and agitation (RR=0.14, 95%CI 0.09 to 0.22, Plt;0.000 01) during emergency. The incidence of postoperative sore throat (RR=0.32, 95%CI 0.19 to 0.55, Plt;0.000 1), hoarse voice (RR=0.09, 95%CI 0.03 to 0.27, Plt;0.000 1), nausea and vomiting (RR=0.46, 95%CI 0.26 to 0.80, P=0.006) was significantly lower in the LMA group. The hemodynamic changes during insertion and extraction of LMA were more stable than ETT, such as the heart rate changes in insertion, extraction and post-extraction period (SMD= –1.18, 95%CI –1.59 to –0.77, Plt;0.000 01; SMD= –1.29 95%CI –1.72 to –0.86, Plt;0.000 01; and SMD= –1.51 95%CI –2.15 to –0.87, Plt;0.000 01, respectively) and the MAP changes in insertion, extraction and post-extraction period (SMD= –1.21, 95%CI –1.39 to –1.02, Plt;0.000 01; SMD= –1.31, 95%CI –1.77 to –0.85, Plt;0.000 01; and SMD= –0.85, 95%CI –1.24 to –0.46, Plt;0.000 1, respectively); but no significant differences in postoperative regurgitation and aspiration (RR=3.00, 95%CI 0.62 to 14.61, P=0.17) and successful insertion on the first attempt (RR=0.99, 95%CI 0.94 to 1.05, P=0.84) were found between the LMA and ETT groups. Conclusion Current evidence indicates that the laryngeal mask airway is superior to endotracheal tube in terms of fewer complications during emergency and after operation as well as stable hemodynamic changes. So, it is a selective, safe and effective airway management for children.
