1、连续超声雾化表面麻醉在纤维支气管镜检查术中的应用作者:冯俊光,杨兆强,袁古治,樊勋作者单位:广东省佛山市顺德区中西医结合医院呼吸内科,广东佛山528333【摘要】目的:探讨连续超声雾化表面麻醉在纤维支气管镜检查术中应用的可行性。方法:60例需做纤维支气管镜检查的患者,根据麻醉方法的不同随机分为A、B两组。A组采用传统的超声雾化表面麻醉,B组在A组基础上进行改良,采用连续超声雾化表而麻醉。观察:①纤维支气管镜检查过程中,患者的血压、心率、呼吸频率和氧饱和度的变化;②检查过程中追加药物次数、药物总量、呛咳程度、操作时间的比较;③麻醉效果。结
2、果:与术前相比,A组术中及术后收缩压明显升高,心率及呼吸频率加快,氧饱和度下降,有显著性差异(P<0.05或P<0.01);与术前相比,B组术中心率及呼吸频率有一过性加快,氧饱和度有一过性下降(PvO.Ol),术毕恢复止常。与A组相比,B组操作时间明显缩短,追加药物次数及总量明显减少,严重呛咳程度明显降低,组间比较有显著性差#(P<0.01);A组和B组的麻醉优良率分别为30.0%和66.7%,组间比较有显著性差异(P<0.01)o结论:连续超声雾化表面麻醉具有麻醉效果好、插管过程安全、镜检操控性好、患者血流动力学稳定等优点,值得推广使
