封堵器单肺通气在临床麻醉中的应用

Application of bronchial blocker one lung ventilation in clinical anesthesia

目的分析封堵器单肺通气法应用于临床麻醉中的可行性及疗效。方法收集需要进行单肺通气并择期进行肺大疱切除术的患者40例,随机分为观察组和对照组,每组各20例。观察组采用封堵器单肺通气,对照组采用双腔支气管导管进行单肺通气。结果两组患者均取得了一次性插管成功,观察组的插管时间明显比对照组短(P<0.05),且术后咽喉疼痛发生率明显比对照组低(P<0.05);两组的肺萎陷以及术野暴露程度、术中定位时间均无明显差异(P>0.05)。结论封堵支气管导管以及双腔支气管导管应用于胸腔镜下的肺大疱切除术均较为安全有效,而采用封堵器单肺通气可有效缩短插管时间,并减轻术后咽喉疼痛及声带损伤等,适用范围更广,值得推广应用。

Objective To analyze the effect and feasibility of bronchial blocker one lung ventilation in clinical anesthesia. Methods Forty patients who should be put one lung ventilation and data selected lung bullae resection were collected and randomly assigned into observation group and control group, 20 cases in each group. Blocker one lung ventilation was applied in observation group, while double-lumen endobronchial tube one lung ventilation in control group. Results The patients in both groups successfully achieved a one-time intubation. The intubation time and incidence of postoperative throat pain in observation group were significantly shorter and lower than those in control group （P 〈 0.05）. There was no significant difference in collapse of lungs, surgical field exposure, and intraoperative positioning time of both groups （P 〉 0.05）. Conclusion Blocker and double-lumen endobronchial tube applying in thoracoscopic lung bullae resection are safer and effective. The application of blocker one lung ventilation can shorten intubation time effectively, alleviate postoperative throat pain and vocal cord injury, thus has wider range of application and worth widely applying.
