摘要 目的:了解小儿急性肺损伤/急性呼吸窘迫综合征(ALI/ARDS)肺功能的变化。方法:20例符合ALI/ARDS诊断标准的机械通气病人作为肺损伤组(ALI组),同期机械通气而无肺损伤病人20例作为对照组(NALI组)。入选同时记录病人的临床资料及呼吸机参数、血气指标。结果:本研究40例全身炎症反应综合征(SIRS)病人中合并多器官功能不全综合征(MODS)10例(25.0%),其中ALI组7例(7/40,占病人的17.5%),NALI组3例(3/40,占病人的7.5%),本组病人死亡7例(占17.5%),其中ALI组死亡5例(占12.5%),NALI组死亡2例(占5.0%),所有死亡病例均并发MODS。ALI组肺顺应性(Cst)、氧合指数(PaO2/FiO2)与NALI组比较明显降低,而肺内分流(Qs/Qt)明显高于NALI组(P<0.01)。发生ALI的病人机械通气参数吸气峰压(PIP)、平均气道压(Pmean)、呼气末正压(PEEP)明显增高,与NALI组比较差异有显著性(P<0.01)。结论:对小儿SIRS/MODS早期监测肺功能的改变,早期诊断和及时干预ALI,阻止MODS的发生、进展,对降低危重儿死亡率有重要意义。
