Risk factors for perioperative atelectasis in pediatric patients undergoing day surgery / 中华麻醉学杂志

ABSTRACT

Objective:To identify the risk factors for perioperative atelectasis in pediatric patients undergoing day surgery.Methods:The data of pediatric patients (aged 28 days-7 yr) undergoing elective surgery in our hospital from January 2021 to April 2021 were retrospectively collected.The pediatric patients were divided into atelectasis group and non-atelectasis group according to the results of postoperative ultrasound examination of the lung.The basic conditions and perioperative indicators of the children were recorded, and logistic regression analysis was used to identify the independent risk factors.Results:A total of 122 pediatric patients were enrolled, there were 68 pediatric patients in atelectasis group, and the incidence of atelectasis was 55.7%.Compared with non-atelectasis group, significant changes were found in the amount of sufentanil, rate of laryngeal mask insertion, and rate of intraoperative inhalation of high-concentration oxygen in atelectasis group ( P<0.05). After adjusting variables such as age, upper respiratory tract infection, and overweight, intraoperative inhalation of high-concentration oxygen (FiO 2>60%) ( OR=2.863, 95% confidence interval 1.148-7.137, P=0.024) and consumption of sufentanil >0.2 μg/kg ( OR=1.214, 95% confidence interval 1.069-1.379, P=0.003) were independent risk factors for perioperative atelectasis in pediatric patients undergoing day surgery. Conclusion:Inhalation of high-concentration oxygen (FiO 2>60%) and consumption of sufentanil >0.2 μg/kg during operation are independent risk factors for perioperative atelectasis in pediatric patients undergoing day surgery.
