摘要 目的观察静脉注射佩尔地平、利多卡因对术后气管拔管时引起的心血管不良反应的预防作用。方法将48例择期行开颅胶质瘤、脑膜瘤切除术患者随机分成4组,A组静脉注射利多卡因1.5 mg/kg,B组静脉注射佩尔地平20μg/kg,C组静脉注射佩尔地平20μg/kg和利多卡因1.5 mg/kg,D组注射同等容量生理盐水。所有患者常规监测ECG、SpO2,记录术前基础值、用药时、吸痰时、拔管时、拔管后1 min、拔管后5 min的心率(HR)、收缩压(SBP)、舒张压(DBP)。结果血压的变化:A组、D组SBP、DBP在吸痰时、拔管时、拔管后1 min、拔管后5 min均升高,并与术前比较,差异有统计学意义(P<0.05);B组、C组SBP、DBP拔管期与术前比较,差异无统计学意义(P>0.05),与对照组D组比较有统计学意义(P<0.05)。HR的变化:B组、D组HR在吸痰时、拔管时、拔管后1min、拔管后5 min均增快,并与术前比较,差异有统计学意义(P<0.05);A组、C组HR在拔管期与术前比较,差异无统计学意义(P>0.05),与对照组D组比较,差异有统计学意义(P<0.05)。结论气管拔管前联合静脉注射佩尔地平和利多卡因能够有效防止气管拔管期间心率增快和血压升高等心血管应激反应。
