摘要
目的探讨重度漏斗胸对儿童心肺功能的影响及手术治疗效果。方法采用多普勒超声心动仪和肺功能检测仪对18例重度漏斗胸患儿(病例组)手术前后进行心肺功能检测,并以相匹配的18例正常儿童作为对照(正常对照组)。结果与正常对照组比较,病例组反映心脏收缩功能的左室射血分数(EF)和每搏输出量(SV)显著降低(P<0.01,P<0.05),反映肺通气功能的残气量(RV)、残气量/肺总量(RV/TLC)、用力肺活量(FVC)和第1秒通气量(FEV1)显著降低(P<0.05或P<0.01)。病例组术后EF、SV、FVC和FEV1较术前显著提高(P<0.05或P<0.01)。结论重度漏斗胸患儿心肺功能均有不同程度损害,以心脏收缩功能和限制性通气障碍为主,手术矫正后可以改善心肺功能。
Objective To explore the cardiorespiratory function and surgical outcomes of children with severe pectus excavatum deformity.Methods Eighteen children with severe pectus excavatum deformity（case group）and 18 matched normal children（normal control group）were examined.Doppler echocardiographic examinations and pulmonary function tests were performed.Results Compared with normal control group,the left ventricular ejection fraction（EF）,stroke volume（SV）,residual volume（RV）,residual volume/total lung capacity（RV/TLC）,forced vital capacity（FVC）and forced expiratory volume in one second（FEV1）in case group were significantly decreased（P〈0.05 or P〈0.01）.The postoperative EF,SV,FVC and FEV1 were significantly higher than the preoperative ones in case group（P〈0.05 or P〈0.01）.Conclusion There is impairment of cardiorespiratory function in children with severe pectus excavatum deformity,which is characterized by decrease of ventricular systolic function and restrictive ventilatory disorder,and surgical treatment may improve the cardiorespiratory function.
