可视双腔支气管导管在胸科手术麻醉应用中的效果观察

Clinical application of the visual double-lumen bronchial tube in thoracic operation

摘要：目的 观察可视双腔支气管导管（V-DLT）在胸科手术麻醉应用中的安全性和有效性。方法 选择美国麻醉医师协会（ASA）分级在Ⅰ～Ⅲ级，需行普通双腔支气管导管（DLT）置入的择期胸科手术患者100例，随机分为A组（V-DLT，n =50）和B组（DLT，n =50）。静脉麻醉诱导后分别置入DLT，A组通过导管内摄像头引导定位，B组通过纤维支气管镜（FOB）引导定位。定位完成后，观察记录插管后的插管时间和插管移位调整时间等；记录术后咽痛和声嘶等发生率。结果 两组患者双腔管平均插管时间A组明显少于B组，两组间差异有统计学意义（P =0.000）。两组患者术后咽喉疼痛、声嘶发生率差异无统计学意义（P >0.05）。结论 V-DLT在胸科麻醉中可以满足单肺通气的要求，其视频头可替代FOB的对位作用。持续地监控隆突可随时指导麻醉医生调整双腔管位置。

Abstract: Objective To observe the safety and effectiveness of visual double lumen tube in thoracic surgery. Methods 40 patients scheduled for thoracic operation with double lumen tube at ASA to I grade III were selected and randomly divided into A group (visual double lumen tube group, n = 50 group), B group (ordinary double lumen tube group, n = 50). After the induction of intravenous anesthesia, the double lumen tube was implanted, and the A group was guided by the intraductal camera, and the B group was guided by the fiberoptic bronchoscope. The positioning is completed, observe and record the average intubation time, intubation after the one-time success rate, pulmonary collapse during the operation; the number of sore throat and hoarseness. Results The average intubation time of the A groups was significantly less than that in the B group, and the difference between the two groups was statistically significant (P = 0.000). The postoperative sore throat, hoarseness in the two groups was no significant difference (P > 0.05). Conclusion The visual double lumen tube can meet the requirement of single lung ventilation in thoracic anesthesia. The video head of the double lumen tube can replace the effect of the fiberoptic bronchoscope. Continuous monitoring the protuberance can guide the anesthesiologist to adjust the position of the double chamber tube at any time.
