摘要
目的 了解漏斗胸矫正术后肺功能的变化及肺功能能否恢复到正常水平。方法 随访27 例漏斗胸术后患儿, 其中男24 例, 女3 例。年龄8～16 岁, 平均手术年龄是4 .98 岁, 平均随访时间为6 .89 年。肺功能检测指标包括肺活量(VC) 、肺总量(TLC) 、残气量(RV) 、功能残气量(FRC) 、最大通气流量( MVV)、用力通气流量(FVC) 、第一秒用力呼出容积(FEV1) 、最大呼气中段流量(MMEF)、呼出肺活量的75% 时的气体流量(V75) 、呼出肺活量的50 % 时的气体流量(V50) 、呼出肺活量的25% 时的气体流量(V25) 、通气含量百分比(BR)等。结果 TLC、FRC、MVV、MMEF、V75 、V50 与正常值相比无显著性差异, 但VC、FVC、FEV1 和V25 与正常值比较有显著性差异。结论 虽然术后患儿的症状明显地改善或消失, 从肺功能可看出术前的限制性通气障碍已消失, 但小气道气流受阻仍然存在。为了防止小气道发生不可逆的改变,
Objective The aim of the study is to assess pulmonary function in patients after operative correction of pectus excavatum. Methods Post operative pulmonary function tests were performed on 27 patients (male 24, female 3). The mean age at the time of operation was 4 years. The pulmonary function tests included vital capacity (VC), total lung capacity (TLC), residual volume (RV), functional residual capacity (FRC), maximal voluntary ventilation (MVV), forced ventilatory capacity (FVC), forced expiratory volume in the first second (FEV 1), maximal midexpiratory flow (MMEF), maximal expiratory flow at 75%, 50%, 25% of vital capacity (V 75 , V 50 , V 25 ), and breathing reserve ratio (BR). Results The mean follow up duration was 6.8 years. The TLC, FRC, MVV, MMEF, V 75 and V 50 did not differ from the normal values, but VC, FVC, FEV, and V 25 decreased significantly compared with the normal values. The RV, RV/TLC increased in 87.5% of patients. Conclusion Although operative correction relieved the symptoms of pectus excavatum, small airway obstruction persists postoperatively. An early operative correction is advocated.
