At present, there is no relevant expert consensus indicating which ventilation device is more efficient for general anesthesia. The present literature review and meta‑analysis compared the effects of the laryngeal mask airway and endotracheal intubation on airway complications during general anesthesia. The keywords ‘laryngeal mask airway’, ‘endotracheal tube’, ‘tracheal tube’, ‘children’, ‘pediatric’, ‘anesthesia’, ‘randomized controlled trials’ (RCTs) and ‘randomized’ were used to perform the literature search in PubMed. Quality assessment was performed by two reviewers according to domains defined by the Cochrane Collaboration tool. Data extraction, risk of bias assessment and quality of evidence assessment were performed with the Cochrane tool. A total of 16 RCTs were included. The results indicated that the effects of the laryngeal mask airway group on heart rate variability [mean difference=‑13.76; 95% CI, ‑18.19‑(‑9.33); P<0.00001], the incidence of hypoxemia [odds ratio (OR)=0.52; 95% CI, 0.28‑0.97; P=0.04] and the incidence of postoperative cough (OR=0.22; 95% CI, 0.12‑0.40; P<0.0001) were significantly lower than those of the endotracheal intubation group. The success rate of one‑time implantation in the laryngeal mask airway group was significantly higher than that noted in the endotracheal intubation group (OR=0.20; 95% CI, 0.07‑0.59; P=0.003). However, no significant differences were noted between the two groups in bronchospasm, sore throat, mucosal injury, nausea and vomiting and reflux aspiration. In conclusion, the results indicated that laryngeal mask airway application can reduce complications during general anesthesia compared with endotracheal intubation.
