摘要 目的:分析右美托咪定对急性心肌梗死行经皮冠状动脉介入( PCI)治疗围术期心率及血压的影响。方法将200例诊断为急性初发ST段抬高心肌梗死患者随机分为研究组和对照组各100例。所有患者发病后12h内行急诊PCI手术治疗,术后入冠心病重症监护室(CCU)留观24h。研究组PCI术前30min给予首剂负荷量推注诱导镇静,随后用微量注射泵持续泵入,采用Ramsay镇静分级,患者维持镇静深度2-3级,对照组行PCI期间依据患者胸痛症状及烦躁程度给予吗啡2-5mg静脉推注或吗啡5-10mg肌内注射,效果不显时给予吗啡2-3mg静脉复推,观察2组患者用药前(T0)及用药后30min(T1)、1.5h(T2)、6h(T3)、12h(T4)、24h(T5)收缩压(SBP)、舒张压(DBP)、心率(HR)变化。结果2组患者T0时SBP、DBP及HR差别无统计学意义(P<0.05);T1、T2、T3、T4、T5研究组SBP、DBP、HR变化均较治疗前有所下降,但下降幅度<15%,同时间点2组HR差异有统计学意义( P<0.05)。结论右美托咪定用于急性心肌梗死患者PCI围术期可平稳降压,稳定心率,对心脏起保护作用,是急性心肌梗死患者PCI围术期较为理想的镇静剂。
