| Objective: To evaluate the pulmonary function in patients with pectus excavatum before and after Nuss procedure.Methods:. A total of 43 patients with pectus excavatum who were treated at our hospital from January 2009 to August 2013 were recruited retrospectively. Among Whom, 28 patients received Nuss procedure and pulmonary function tests. The Pulmonary function test of these patients were assessed at 3 days before, 3 months after and 1 year after surgery. The pulmonary function indexes including VC, RV, TLC, MVV, FEV1, MEF50 were collected. The SPSS version 16.0 was used to analysis the data.Results:Compared with the preoperative data, RV at 3 months after operation was increased (P> 0.05) while the RV at lyear after operation was reduced (P<0.05). MVV and MEF50 at 3 months after operation were unchanged a litter 3 months after operation(P> 0.05) while MVV and MEF50 at 1 year after operation were increased(P<0.05). TLC and FEV1 at 3 months after operation were reduced (P<0.05), while they were recovered at 1 year after operation (P> 0.05). VC at 3 months after operation was reduced (P<0.05), but it was increased at 1 year after operation (P<0.05).Conclusions(1) NUSS Procedure has a protective effect on thoracic development for patients with pectus excavatum and preventing a further reduction of the volume of patients’chest;(2) Compared with preoperative data, the pulmonary function indexes were reduced at 3 months after surgery for patients with pectus excavatum.(3) Compared with preoperative data, the pulmonary function indexes were recovered at 1 year after surgery for patients with pectus excavatum. |
