摘要 目的探讨丙美卡因行咽喉、气管内表麻对全麻诱导时血流动力学的影响。方法择期全麻下行腹部手术的中老年患者40例随机分为丙美卡因组和对照组,每组20例。常规麻醉诱导后,丙美卡因组均用体积分数0.5%的丙美卡因对咽喉、气管内进行喷雾,然后行气管插管;对照组均直接气管插管。记录诱导前、诱导后2min、插管后即刻、插管后2、5、10min时的收缩压、舒张压、平均动脉压、心率、收缩压与心率乘积,并记录诱导插管前、后ST-T改变。结果丙美卡因组插管后收缩压、舒张压、平均动脉压、心率、收缩压与心率乘积与诱导前比无统计学意义,丙美卡因组插管后上述指标与对照组比较有统计学意义(P<0.05),且两组均未出现明显ST-T改变。结论全麻插管前丙美卡因行咽喉、气管内表麻可有效抑制气管插管的不良应激反应,能维持全麻诱导时的血流动力学的稳定。
