Ann Am Thorac Soc:极早产儿成年前请留心肺部功能发育

2015-01-27 MedSci MedSci原创

早产儿(EP)出生后的呼吸系统前景不明。比较在以人群为基础的出生队列中长大成人的早产儿的呼吸健康状态和肺功能。 研究人员选取了45例(51,88 %)符合条件成年人,均为1982年-1985年间出生于挪威西部的胎龄在≤ 28周 或者体重≤ 1000g的早产儿,与对照组相匹配。已有相似的研究完成了对早产儿在18岁成年时期的调查结果,使其可以进行纵向比较。 和对照组相比,极早产儿组的第一秒用力呼气

早产儿(EP)出生后的呼吸系统前景不明。比较在以人群为基础的出生队列中长大成人的早产儿的呼吸健康状态和肺功能。

研究人员选取了45例(51,88 %)符合条件成年人,均为1982年-1985年间出生于挪威西部的胎龄在≤ 28周 或者体重≤ 1000g的早产儿,与对照组相匹配。已有相似的研究完成了对早产儿在18岁成年时期的调查结果,使其可以进行纵向比较。

和对照组相比,极早产儿组的第一秒用力呼气量(FEV1)、肺活量25 75 %的用力呼气量(FEF25-75)、以及FEV1/FVC分别减少了1.02,1.26和0.88(p < 0.001,p < 0.001,p = 0.002);气道阻力(kPa / l / sec)增加(0.23 vs 0.18;p = 0.23)。尽管新生儿支气管肺发育不良(BPD)水平上升,但残气量/肺总容量(RV/TLC)没有增加(p=0.003)。支气管对乙酰甲胆碱响应(剂量反应曲线斜率)(3.16 vs 0.85,p = 0.005)和支气管不稳定性指数(7.5% vs 4.8%,p = 0.044)增加,支气管对运动和沙丁胺醇响应能力与对照组相似,呼出一氧化氮含量也相似(15.2 vs 15.1;p = 0.903)。在极早儿组中和对照组中从18岁到25岁肺功能的变化在很大程度上是相似的,两组中呼吸道症状不明显,基于以上的结果,可以得出推论:极早产儿的肺部功能异常会持续到成人以后。不过,大多数差异都比较小,而且FEV1的缺损可以通过β受体激动剂来挽救。呼吸系统症状很少见,而且,18岁至25岁的肺部功能追踪发现极早产儿与正常出生人群没有变化。
