Abstract

Abstract: PURPOSE: To explore the risk factors of laryngospasm among patients with oral and maxillofacial surgery in post-anesthetic care unit. METHODS: From March 2020 to June 2021, 1 428 patients undergoing oral and maxillofacial surgery in PACU were recruited. Socio-demographic and surgical-anesthesia related characteristics of participates were evaluated and the patients were divided into non-laryngospasm group and laryngospasm group. SPSS 22.0 software package was used to analyze risk factors of laryngospasm among patients. RESULTS: A total of 1 428 patients after oral and maxillofacial surgery were selected in this study, including 868 males and 560 females, aged 20-78 years, with an average age of (46.34±11.23) years. There were 114 patients with laryngospasm in post-anesthetic care unit, and the incidence rate was 7.98%. Logistic analysis showed that age (P=0.002), smoking (P=0.016), BMI(P=0.003), history of upper respiratory tract (P=0.004), Ramsay sedation(P=0.006) and times of sputum suction (P=0.047) in post-anesthetic care unit were the risk factors of laryngospasm. CONCLUSIONS: Old age, smoking, obesity, history of upper respiratory tract, lack of sedation and repeated sputum suction were the risk factors of laryngospasm in patients with oral and maxillofacial surgery in post-anesthetic care unit. Anesthesia care providers should strengthen the awareness of early warning of laryngospasm, promote the observation and preventive measures of laryngospasm, so as to improve the safety of patients during perioperative anesthesia.
