摘要 目的观察神经刺激器定位腰丛神经阻滞对下肢手术患者MAP、HR及SpO2的影响。方法45例股骨中段以下手术患者随机均分为三组:A组,神经刺激器定位下行神经阻滞;B组,行连续硬膜外麻醉;C组,单侧腰麻。A组在神经刺激器定位下行腰丛及坐骨神经阻滞,以2mA强度刺激,出现相应区域肌群收缩后渐减至0.3mA仍有收缩,回抽无血无液,给试验量3~5ml确定位置正确,一次注入0.5%罗比卡因20~25ml,记录术中MAP、HR、SpO2,并与B、C组相比较。结果A组MAP、HR在手术过程中较B、C组平稳(P<0.05,P<0.01)。三组间SpO2变化的差异无显著意义。结论神经刺激器定位下肢神经阻滞应用于下肢手术中定位准确,生理干扰小,镇痛效果好。
