改进后的电子内镜用于双腔支气管导管定位的应用研究

Application study on the improved electronic endoscope for positioning by double-lumen endobronchial tube

目的改进后的工业用电子内镜用于双腔支气管导管(DLT)插管定位,比较肺部听诊法、纤维支气管镜(纤支镜)法判断DLT定位的准确性。方法将220例需DLT单肺通气患者随机分为3组,分别用肺部听诊法(A组,n=70)、纤支镜法(B组,n=75)及气道电子内镜法(C组,n=75)判断DLT的位置。结果肺部听诊法、纤支镜法、气道电子内镜法定位准确率分别为68.6%、100%、100%。结论气道电子内镜法可达到与纤支镜相似的定位效果,在同步教学和资料收集等方面优于纤支镜,而低廉的价格(纤支镜价格的十分之一)使之在基层医院广泛应用成为可能。

Objective The improved electronic endoscope were used to position the double-lumen endotracheal intubation,lung auscultation and bronchoscopy were judge the accuracy of positioning double-lumen endotracheal intubation.Methods 220 patients requiring double lumen bronchial tube one-lung ventilation were randomly divided into 3 groups,the number of the cases in the 3 groups were 70,75 and 75.After bronchial intubation,lung auscultation,bronchoscopy Law and airway electronic endoscope were used to judge the location of double-lumen endobronchial tube.Results The lung auscultation,fiberoptic bronchoscopy law,e-endoscopic method of airway positioning accuracy was 68.6%,100%,100%.Conclusion Airway electronic endoscope method can achieve similar position with the bronchoscopy results,the synchronization and data collection of teaching is better than bronchoscopy,and low price（the price of one-tenth of bronchoscopy）to widely applicated in the primary hospital possible.
