[摘要] 目的 探讨Coopdeeh支气管封堵器在困难气道患者行单肺通气的效果与意义。 方法 选取术前经评估为气道困难的患者60例，随机分为观察组与对照组各30例。观察组使用Coopdeeh支气管封堵器进行单肺通气，对照组使用双腔气管导管进行治疗。比较两组患者不同通气方式治疗后插管成功率、插管时间、各项生命体征变化等指标。 结果 应用支气管封堵器的观察组患者插管时间及肺萎陷质量、术后咽痛声嘶人数指标均显著优于对照组(P<0.05)且患者生命体征中气道压力及呼末二氧化碳分压行支气管封堵术的观察组显著低于对照组(P<0.05)。 结论 对困难气道患者行Coopdeeh支气管封堵器效果确切，并发症少，尤其适合困难气道患者行单肺通氣。
