Abstract:
Objective:To investigate the effects of endotracheal intubation anesthesia versus laryngeal mask anesthesia on the incidence of pulmonary infection in young children undergoing surgery. Methods:A total of 100 young children who underwent surgery under general anesthesia in Hangzhou Children's Hospital from January 2020 to December 2020 were included in this study. They were randomly allocated into the endotracheal intubation anesthesia and laryngeal mask anesthesia groups ( n = 50/group). The symptoms of respiratory tract infection (nasal congestion, cough, sputum ringing, rale, and sputum excretion) and the incidence of pulmonary infection evaluated 24 hours after surgery were compared between the two groups. At the same time, the pathogens of infection and perioperative conditions as well as prognosis were also compared between the two groups. Results:The incidences of nasal obstruction, cough, sputum ringing, rale, sputum excretion, and pulmonary infection were 56.0% (28/50), 42.0% (21/50), 14.0% (7/50), rale 38.0% (19/50), 16.0% (8/50), and 38.00 (19/50) respectively in the endotracheal intubation anesthesia group, which were significantly higher than those in the laryngeal mask anesthesia group [28.0% (14/50), 14.0% (28/50), 4.0% (8/50), 24.0% (12/50) 4.0% (2/50), 6.0%(3/50), χ2 = 12.18, 21.47, all P < 0.001]. A total of 34 strains of pathogens were detected in the two groups, including 4 strains in the laryngeal mask anesthesia group and 30 strains in the endotracheal intubation anesthesia group. The 34 strains of pathogens included 7 strains of gram-positive bacteria (20.6%), 23 strains of gram-negative bacteria (67.6%), and 4 strains of fungi (11.8%). There was no significant difference in pathogen composition between the two groups ( χ2 = 1.04, P = 0.310). The time to recovery and the time to extubation in the laryngeal mask anesthesia group were (10.3 ± 3.1) minutes and (13.5 ± 2.4) minutes, which were significantly shorter than those in the endotracheal intubation anesthesia group [(16.1 ± 5.1) minutes, (19.5 ± 4.1) minutes, t = 3.17, 7.19, both P < 0.05]. There were no significant differences in the proportion of children who needed prolonged hospitalization and the proportion of children scheduled to undergo readmission between the two groups (both P > 0.05). Conclusion:Laryngeal mask anesthesia is simpler to operate, remarkably decreases the incidence of pulmonary infection, and is safer compared with endotracheal intubation anesthesia. Therefore, laryngeal mask anesthesia is preferred for general anesthesia for surgery in young children. The study is of great innovation and science.
