纤支镜引导双腔支气管插管

Intubation of Double-lumen Endobronchial Tube with Fiberoptic Bronchoscope

目的:研究纤支镜引导下双腔支气管导管插管的一次成功率和定位情况。方法:选择ASAⅠ-Ⅱ级的胸科手术患者320例,随机分成试验组(160例)和对照组(160例)。试验组在纤支镜引导下插入双腔支气管导管并确定管端位置后固定,对照组在普通喉镜显露下插入双腔支气管导管,再用纤支镜判断管端所在位置。结果:试验组双腔支气管导管插入一次成功率为99·98%,管端定位准确率达99·99%,对照组双腔支气管导管插入过深发生率24·35%,插入过浅发生率为15·23%,总错位率达39·58%,定位率仅占61·56%。结论:纤支镜引导双腔支气管导管插管均一次成功,管端定位准确,是目前双腔支气管导管插管及定位的最佳方法。

Objective： To study the intubating and positioning of double - lumen endobmnchial tube （DLT） with fiberoptic bronchoscope （FOB） . Methods： 320 （ASA Ⅰ - Ⅱ） patients undergoing thoracic surgery were randomly assigned into Experimental group （160 cases） and comparison group （160 cases） . In experimental group, intubate Double- lumen endobronchial tube with fiberoptic bronchoscope and posite the tube. In comparison group, normal laryngoscope was used for the intubating of DLT and the position of the tub was checked by the fiberoptic bronchoscope. Results： In experimental group, the successful ratio for intubation at the first attempt was 99.98% and the accurate ratio of positioning was 99.99%. In comparison group, the incidence for deeper intubation was 24.35%, and the incidence for shallower intubation was 15.23% .The ratio of mis - positioning was 39.58% and the ratio of right positioning is 61.56%. Conclusion： Intuhating and positioning of double- lumen endobronchial tube （DLT） with fiberoptic bronchoscope （FOB） can be. successful at the first time. It is the optimal choice at present.
