摘要 目的 探讨肺表面活性物质 (PS)预防新生儿呼吸窘迫综合征 (RDS)的有效性及临床价值。方法2 5例高危早产儿气管内滴注单剂预防量PS ,并与 2 5例未用PS的高危早产儿进行前瞻性临床对照研究。结果 预防组早产儿在生后 15min~ 6h ,平均 ( 3 .4± 1.9)h给予预防量PS ,其临床症状及血气指标明显改善 ,氧疗时间、机械通气时间和住院天数分别为 ( 9.5± 6.9)d ,( 2 .6± 3 .8)d和 ( 4 0 .8± 17.8)d。而对照组氧疗时间、机械通气时间和住院天数分别为 ( 13 .1± 6.5 )d ,( 4 .3± 3 .2 )d和 ( 5 3 .8± 2 7.8)d ,两者比较差异具有显著性 (P <0 .0 5 )。预防组RDS发生率 2 0 %、病死率 8%虽较对照组RDS发生率 3 2 %和病死率 12 %低 ,但两者间差异在统计学上无显著性意义 (P >0 .0 5 )。结论 PS预防性给药可改善早产儿临床症状及血气指标 ,缩短氧疗时间、机械通气时间和住院天数 ,对高危早产儿RDS具有减轻病情作用。
