目的探讨肥胖儿童术前状态、年龄、体重指数与围手术期气道事件的关系。方法 154例2~14岁的手术患儿依据其体重指数分入正常组、超重组及肥胖组,观察其术前状态、年龄、体重指数与围手术期气道事件的关系。结果肥胖儿童气道阻塞发生率较高。且气道不良事件的风险因素为肥胖、年龄小于10岁及有阻塞性睡眠呼吸暂停病史等。结论肥胖儿童较体重正常儿童具有更高的围手术期不良气道事件发生率。 Objective To investigate the relationship between preoperative status, age, body mass index and airway events in obese children. Methods A total of 154 children aged 2-14 years were divided into normal group, overweight group and obesity group according to their body mass index (BMI). The relationship between preoperative status, age, BMI and perioperative airway events was observed. Results Obese children had a higher incidence of airway obstruction. The risk factors for adverse airway events were obesity, age less than 10 years and history of obstructive sleep apnea. Conclusion Obese children have a higher incidence of perioperative adverse airway events than normal-weight children.
