胸膜外手术治疗小儿动脉导管未闭的研究

Clinical study of extrapleural approach for children′s patent ductus arteriosus

为探讨小儿动脉导管未闭胸膜外手术结扎方法的疗效和优点，将３～１４岁小儿动脉导管未闭７３例随机分为胸膜外组４０例和剖胸组３３例，均采用动脉导管结扎方法。结果：２组患儿的年龄、动脉导管直径基本相同（Ｐ＞０．０５）；但２组的输血率（Ｐ＜０．００１）、并发症发生率、术后住院时间均有显著性差异（Ｐ＜０．０５）。提示：胸膜外手术治疗小儿动脉导管未闭，手术创伤小、输血少、肺部并发症少、术后恢复快。

おhe purpose of this study was to study advantages of extrapleural approach for children′s patent ductus arteriosus (PDA)and 73 children with PDA aged from 3 to 14 years old were divided into extrapleural group (n=40) and transpleural group (n=33) at random.Ligation of ductus was used in the same way,but pleural drainage was not used in extrapleural group.The results showed that the age of children and the diameter of ductus were similar in both groups(P>0.05).The blood transfusion rate,complication rate and postoperative hospitalized days in extrapleural group were lower than those in transpleural group (P<0.001,P<0.05 and P<0.05 respectively).All patients in extrapleural group were cured and l case died in transpleural group.Conclusion:extrapleural approach for children′s PDA obviates the pleural drainage tube and minimizes damage in the surgical repair.Blood transfusion and lung complication decrease,indicating that this technique is safe and useful.
