Coopdech管与双腔管在开胸术的应用及对术后声嘶喉痛的对比研究

目的 比较Coopdech支气管填塞管与双腔管在单肺通气应用的效果及对患者术后声嘶喉痛的影响。方法 择期全麻下行食管癌根治术患者100例，ASAⅠ～Ⅲ级,随机分成C组和D组（n=50）。C组采用单腔气管导管（ID7.5-8.0）复合Coopdech支气管填塞管，D组采用双腔支气管导管（35F-37F）。观察气管插管时间、插管尝试次数、术中导管移位次数、支纤镜使用次数，插管前后血流动力学变化，单肺通气时术侧肺塌陷及术野暴露情况，患者术后声嘶喉痛发生率及严重程度。结果 两组间相比插管时间C组比D组长，插管尝试次数、术中导管移位次数、支纤镜使用次数D组均比C组多，插管前后MAP、HR变化率D组均比C组高，单肺通气时肺塌陷D组比C组好，患者术后声嘶、喉痛总体发生率D组比C组高(P<0.05)。单肺时术野暴露情况及术后在PACU、1d、2d、3d、>3d时患者声嘶、喉痛严重程度组间比较差异无统计学意义(P>0.05)。结论 Coopdech支气管填塞管复合单腔管双肺阻隔效果确切，插管定位方便快捷，刺激小，可减少患者术后声嘶喉痛发生率，具有一定的临床应用前景。

A comparison study of effects on postoperative hoarseness and sore throat between Coopdech bronchial blocker and double-lumen tube used in thoracotomy

Objective To compare the performance between Coopdech bronchial blocker and double-lumen tube in one-lung ventilation and their effects on postoperative hoarseness and sore throat. Methods One hundred patients scheduled for esophageal cancer radical operation under general anesthesia in the Sun-Yat Sen Cancer Center were selected and randomly divided into group C and group D. One-lung ventilation was achieved by Coopdech bronchial blocker combining with single-lumen endotracheal tube (ID7.5-8.0 group C) and...
