Purpose: This study investigated the clinical effects of laryngeal mask and tracheal intubation on infant anaesthesia.

Methods: A total of 60 cases of children undergoing surgery were selected in our hospital from September 2013 to June 2015. They were randomly divided into two groups: study and control groups. The study group underwent laryngeal mask anaesthesia, whereas the control group underwent tracheal intubation anesthesia. Extubation and waking time were observed in the two groups. Cases of postoperative hoarseness, vomiting, dysphoria, bucking, and other complications were determined in the two groups.

Results: The extubation and waking time in the study group were significantly less than those in the control group, and the difference was statistically significant (P<0.05). Cases of postoperative hoarseness, vomiting, dysphoria, bucking, and other complications in the study group were less than those in the control group, and the difference was also statistically significant (P<0.05). After administration of the study group with laryngeal mask anesthesia for 3 and 10 min, the Heart Rate (HR) scores were 76.5 ± 8.8 and 77.4 ± 6.9, respectively; the postoperative HR score was 80.7 ± 9.5. These HR scores were significantly superior to those of the control group, and the difference was statistically significant (P<0.05). The SPO₂ score (97.7 ± 2.9) after administration with laryngeal mask anesthesia for 3 min of the study group was significantly superior to that of the control group (93.3 ± 3.2). The postoperative sedation score of the study group was superior to that of the control group, and the difference was statistically significant (P<0.05).

Conclusion: Laryngeal mask anesthesia can significantly reduce the extubation and waking time, as well as the postoperative complications. Its clinical effect is significantly superior to that of tracheal intubation anesthesia and is thus worth promoting.
