METHODS: A retrospective study was conducted of children with obstructive sleep apnoea who underwent laryngo-tracheo-bronchoscopy intra-operatively, performed by a single ENT surgeon from February 2016 to July 2019. Pre- and post-operative minimum oxygen saturation, apnoea-hypopnoea index, and oxygen desaturation index were recorded.
RESULTS: Sixty-five children were identified; 34 were aged less than three years and 31 were aged three years or more. 77 per cent and 13 per cent respectively had an airway abnormality; the t-test showed a significantly higher mean oxygen desaturation index and lower mean minimum oxygen saturation pre-operatively compared to children without an airway abnormality.
CONCLUSIONS: An update of the surgical pathway for children aged less than three years with obstructive sleep apnoea is required to include laryngo-tracheo-bronchoscopy intra-operatively. A t-test analysis of the pre-operative respiratory parameters suggests that airway abnormalities contribute to obstructive sleep apnoea severity.
方法:对阻塞性睡眠呼吸暂停患儿进行回顾性研究,2016年2月至2019年7月由一名耳鼻喉科外科医生进行。术前和术后最低氧饱和度,呼吸暂停-呼吸不足指数,记录氧饱和度指数。
结果:确认了65名儿童;34名年龄在3岁以下,31名年龄在3岁以上。分别有77%和13%的人患有气道异常;t检验显示,与无气道异常的儿童相比,术前平均氧饱和度指数明显较高,平均最低氧饱和度较低。
结论:需要更新3岁以下儿童阻塞性睡眠呼吸暂停的手术途径,包括术中喉气管支气管镜检查。术前呼吸参数的t检验分析表明,气道异常会导致阻塞性睡眠呼吸暂停的严重程度。
