改良型Carlens双腔导管在单肺通气时的应用

目的 对改良型Carlens双腔导管与左置Robertshaw双腔导管在单肺通气时的应用进行评价.方法 选择ASA Ⅰ或Ⅱ级术中需行单肺通气的成年患者60例,随机分为改良型Carlens双腔导管组(C组)和左置Robertshaw双腔导管组(R组),每组30例.观察两组患者插管定位时间、盲插成功率、气道峰压增加率、导管移位率、需行纤支镜(FOB)再检查次数及术野暴露情况.结果 C组盲插成功率明显高于R组(P<0.05),导管移位率和需行纤支镜再检查次数明显少于R组(P<0.05),术野暴露情况优于R组(P<0.05).结论 改良型Carlens双腔导管应用于单肺通气方便、快捷,肓插成功率高,其效果可能优于左置Robertshaw双腔导管.

Application of modified Carlens DLT for one-lung ventilation

Objective To compare the application of Carlens double lumen tuber(DLT) and left Robertshaw DLT in one-lung ventilation(OLV).Methods Sixty adult patients undergoing were randomized into modified Carlens DLT(group C) and left Robertshaw DLT(group R) with 30 cases each.The intubation and positioning time,success rate of blind-intubation,the rates of peak airway pressure increase,the frequency of catheter displacement,and FOB usage,exposure condition of the surgery field,the incidence of postoperative pharyngalgia and hoarseness were recorded.Results The blind-intubation success rates of group C and R were 86% and 46%,respectively(P<0.05).The patients of catheter displacement were 3(10%) in group C and 12(40%) in group R(P<0.05).The cases of FOB usage were 3 and 12(P<0.05),respectively.The worse exposure condition rate of the surgery field of group C and R were 1 and 8(P<0.05).respectively.There was no significant difference between the two groups in the positioning time,the increase rates of peak airway pressure and the incidence of postoperative pharyngalgia and hoarseness.Conclusion The application of modified Carlens DLT is convenient with high blind-intubation success rates,which may be superior to left Robertshaw DLT in OLV.
