摘要

背景:本研究旨在探讨右美托咪定对脓毒性休克患者微循环的影响:本研究旨在探讨右美托咪定对早期脓毒性休克患者微循环的影响:这是一项单中心前瞻性研究。方法:这是一项单中心的前瞻性研究,研究对象为经初步液体复苏后仍需去甲肾上腺素维持目标动脉压的早期脓毒性休克患者。在基线和输注右美托咪定(0.7mcg/kg/h)1小时期间测量了血流动力学和气体分析变量、舌下微循环参数。为阐明右美托咪定对微循环影响的可能机制,在进行中期分析后,分别在基线、不同剂量右美托咪定(0.7和0.3 mcg/kg/h)稳定后1小时以及右美托咪定停止后2小时调查了右美托咪定对微循环和儿茶酚胺水平的剂量效应关系:44名脓毒性休克患者是在初步复苏后入院的。与基线相比,输注右美托咪定后总血管密度和灌注血管密度均有统计学意义的增加,这与右美托咪定的剂量有关。输注右美托咪定期间,血浆去甲肾上腺素和多巴胺水平明显下降。输注右美托咪定导致的血浆去甲肾上腺素水平变化与总血管密度和灌注血管密度的变化密切相关:结论:在成人脓毒性休克复苏患者中,右美托咪定可改善微循环,这可能与血浆儿茶酚胺水平有关。不过,应进行双盲大样本研究以验证结果:试验注册:Clinicaltrials.gov NCT02270281。注册日期:2014年10月16日。
