目的前瞻性对比分析漏斗胸患者Nuss手术前后患者肺功能的变化。方法漏斗胸患者于Nuss手术前3d和术后3个月行肺功能检查,通过对比前后肺通气功能〔用力肺活量(FVC)、1s用力呼气容积(FEV1)〕和肺容积〔肺活量(VC)、残气量(RV)和肺总量(TLC)〕的变化,分析Nuss手术前后患者肺功能的变化。结果 2010年6月至2012年6月,华西医院共有94例漏斗胸患者(男78例,女16例)完成了这项研究。年龄5~32岁,平均(15.4±4.5)岁;术后住院天数3~9d,平均(5.9±1.2)d。漏斗胸患者术后FVC、FEV1、VC、TLC较手术前降低(P<0.05),RV手术前后差异无统计学意义。结论漏斗胸患者术前肺功能比正常同龄人差,手术后3个月的肺功能(FVC、FEV1、VC、TLC)较术前低。
Objective To prospectively analyze the changes of pulmonary function in patients with funnel chest before and after Nuss operation. Methods Pulmonary func- tions were performed on 3 days before and 3 months after Nuss operation. The lung function (FVC, 1 FEV1) and pulmonary volume (VC) , Residual volume (RV) and total lung volume (TLC)] were measured before and after Nuss operation. Results From June 2010 to June 2012, 94 patients with funnel chest (78 males and 16 females) in West China Hospital completed the study. They were 5 to 32 years old with an average of (15.4 ± 4.5) years. The postoperative hospital stay was 3 to 9 days, with an average of 5.9 ± 1.2 days. FVC, FEV1, VC and TLC in patients with funnel chest decreased compared with those before operation (P <0.05), and there was no significant difference between before and after RV operation. Conclusions Preoperative functioal lung function of patients with funnel chest is worse than that of normal peers. The pulmonary function (FVC, FEV1, VC, TLC) at 3 months after operation is lower than that before operation.
