Abstract
Background: To compare perioperative adverse events between general anesthesia with endotracheal tube (ETT) and general anesthesia with laryngeal mask airway (LMA) in patients undergoing laparoscopic hysterectomy.
Materials and methods: This was a large sample retrospective, propensity score-matched (PSM) study. We collected the data of 6739 female patients who underwent laparoscopic hysterectomy between January 2016 and June 2021 in our hospital, China. Patients were divided into two groups (ETT group and LMA group) according to different airway management modes. Data on all perioperative adverse events were collected. PSM analysis was performed to control confounding factors and differences in baseline values between the two groups. Finally, 4150 female patients were recruited after PSM.
Results: The total number of patients taking intraoperative vasoactive drugs during surgery was higher in the ETT group than in the LMA group (P = 0.04). The LMA group had a higher incidence of vomiting (51 [2.46%]) and somnolence (165 [7.95]) in the postanesthesia care unit (PACU) than the ETT group (71 [3.42%] and 102 [4.92%], respectively) (P = 0.02 and P < 0.001). Hypothermia was significantly higher in the LMA group (183 [10.36%]) than in the ETT group (173 [8.34%]) in the PACU (P = 0.03). The number of patients with sore throat was significantly higher in the ETT group (434 [20.02%]) than in the LMA group (299 [14.41%]) in the ward (P < 0.001). Other variables such as hypoxemia, moderate to severe pain, abdominal distension, diarrhea, sleep disorders, wound bleeding, and skin itch were not significantly different between the two groups (P > 0.05).
Conclusion: The ETT group had more incidences of vomiting, sore throat, and cough complications and needed more drug treatment than the LMA group. LMA is a better airway management mode and LMA general anesthesia can be safely used in patients undergoing laparoscopic nonemergency hysterectomy.
