Comparison of domestic infantile type video intubationscope and stethoscope in positioning of double-lumen endobronchial tube*

摘要:

目的 比较国产小儿型明视插管软镜（VIS）和听诊法用于双腔支气管导管（DLT）定位的效果。 方法 择期胸科手术需要单肺通气的患者 100 例，随机分为国产小儿型明视插管软镜组（V 组）和听诊法组（S 组），每组 50 例。行双腔支气管插管后，分别以 VIS 检查法和听诊法判断和调整 DLT 的位置，再以纤维支气 管镜（FOB）复核，记录两组 DLT 定位时间及正确率。 结果 V 组患者 DLT 定位时间明显短于 S 组（P <0.05）， 总定位准确率明显高于 S 组（P <0.05）。 结论 国产小儿型 VIS 用于 DLT 定位方便快速，定位准确率高，值 得临床推广应用。

Abstract:

Objective To compare the effect of the domestic infantile type video intubationscope (VIS) and stethoscope in positioning of double-lumen endobronchial tube (DLT). Methods 100 cases of patients underwent elective thoracic surgery requiring single lung ventilation were randomly divided into two groups: domestic infantile type video intubationscope group (group V) and stethoscope group (group S), with 50 cases in each. After intubating with a DLT, the positions of DLT were judged and adjusted by VIS (group V) and stethoscope (group S) respectively, and then reviewed by fberoptic bronchoscopy (FOB), the positioning time and accuracy were recorded. Results Comparing with the group S, the positioning time of DLT was signifcantly shorter and the total positioning accuracy of DLT was significantly higher in group V (P < 0.05). Conclusion It is easy and quickly, high accuracy with domestic infantile type video intubationscope in positioning of DLT, which is worthy of clinical popularization and application.
