国产小儿型明视插管软镜和听诊法用于双腔支气管导管定位的对比研究

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(P0.05),总定位准确率明显高于S组(P0.05)。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。

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

Objective To compare the effect of the domestic infantile type video intubationscope (VIS) andstethoscope in positioning of double-lumen endobronchial tube (DLT). Methods 100 cases of patients underwentelective thoracic surgery requiring single lung ventilation were randomly divided into two groups: domesticinfantile 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 wererecorded. Results Comparing with the group S, the positioning time of DLT was signifcantly shorter and the totalpositioning 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 clinicalpopularization and application.
