摘要 目的探讨应用不同血管活性药物对感染性休克患者胃黏膜pH值(Phi)的影响。方法将48例感染性休克患者按所应用的血管活性药物分为3组各16例,A组给予多巴胺,B组给予去甲肾上腺素,C组给予多巴酚丁胺加去甲肾上腺素。观察用药前(基础值)和用药后6,12,24和48 h胃黏膜Phi变化,同时观察用药前(基础值)和用药后6 h血流动力学指标。结果3组患者用药前胃黏膜Phi差异无显著性;与基础值相比,A组用药后6,12,24和48 h胃黏膜Phi无显著变化;B组和C组用药后6,12,24和48 h胃黏膜Phi均明显高于基础值(均P<0.05);用药后C组胃黏膜Phi均明显高于A组和B组(均P<0.05),A组与B组间用药后6,12,24和48 h胃黏膜Phi差异有显著性(均P<0.05)。3组患者用药前血流动力学指标差异无显著性(均P>0.05);与基础值相比,3组患者在用药后平均动脉压(MAP)、心脏指数(CI)均明显升高;B组和C组肺毛细血管楔压(PAWP)与中心静脉压(CVP)均明显升高(均P<0.05);A组心率明显增快(P<0.05)。结论感染性休克患者应用去甲肾上腺素和多巴酚丁胺均使胃黏膜Phi升高,多巴酚丁胺与去甲肾上腺素联合使用升高胃黏膜Phi较单独应用去甲肾上腺素和多巴胺者明显;多巴胺、去甲肾上腺素和多巴酚丁胺均能改善感染性休克患者的全身血流动力学状态。
