Abstract

Background: The association between the concentration of atmospheric particulate matter on the day of surgery and the occurrence of intra-operative hypoxaemia in children receiving general anaesthesia is unclear.

Objective: To investigate the association between the exposure to particulate matter on the day of surgery and the occurrence of intra-operative hypoxaemia, defined as a pulse oximetry oxygen saturation of less than 90% for more than 1 min, in children.

Design: Retrospective study.

Setting: Single-centre.

Participants: Children aged 18 years or younger who received general anaesthesia between January 2019 and October 2020.

Intervention: Information on daily levels of particulate matter with a diameter 10 μm or less and 2.5 μm or less measured within a neighbourhood corresponding to the area defined by the hospital's zip code was obtained from publicly available air-quality data.

Main outcome measures: The primary outcome was intra-operative hypoxaemia, defined as a pulse oximetry oxygen saturation of less than 90% lasting for more than 1 min, manually verified by anaesthesiologists using vital sign registry data extracted at 2 s intervals.

Results: Of the patients finally analysed, 3.85% (489/13 175) experienced intra-operative hypoxaemia. Higher levels of particulate matter 10 μm or less in diameter (≥81 μg m -3 , 17/275, 6.2%) were associated with an increased occurrence of intra-operative hypoxaemia compared with lower particulate matter concentrations [<81 μg m -3 , 472/12 900, 3.7%; adjusted odds ratio, 1.71; 95% confidence interval (CI), 1.04 to 2.83; P  = 0.035].

Conclusion: The level of particulate matter on the day of surgery pose a risk of intra-operative hypoxaemia in children receiving general anaesthesia. If the concentrations of particulate matter 10 μm or less in diameter on the day of surgery are high, children receiving general anaesthesia should be managed with increased caution.

韩国儿童接受全身麻醉时的大气颗粒物与低氧血症:回顾性分析。
背景:在接受全身麻醉的儿童中,手术当天大气颗粒物浓度与术中低氧血症发生率之间的关系尚不清楚:目的:研究手术当天大气颗粒物的暴露量与儿童术中低氧血症发生率之间的关系,术中低氧血症是指脉搏血氧饱和度低于90%的时间超过1分钟:设计:回顾性研究:参与者2019年1月至2020年10月期间接受全身麻醉的18岁或以下儿童:从公开的空气质量数据中获取与医院邮政编码所定义的区域相对应的社区内测量到的直径为 10 μm 或更小和 2.5 μm 或更小的颗粒物的日水平信息:主要结果为术中低氧血症,定义为脉搏血氧饱和度低于 90% 持续时间超过 1 分钟,由麻醉师使用每隔 2 秒提取的生命体征登记数据进行人工验证:在最终分析的患者中,3.85%(489/13 175)的患者在术中出现低氧血症。与较低的颗粒物浓度相比,直径在 10 μm 或以下的颗粒物浓度越高(≥81 μg m-3,472/12 900,3.7%),术中低氧血症发生率越高[结论:手术当天的颗粒物水平会给接受全身麻醉的儿童带来术中低氧血症的风险。如果手术当天直径为 10 μm 或更小的颗粒物浓度较高,则接受全身麻醉的儿童应更加谨慎。
