【摘要】:探討右美托咪定復(fù)合七氟醚控制性降壓用于高血壓患者鼻內(nèi)窺鏡手術(shù)的效果。選擇鼻內(nèi)窺鏡手術(shù)高血壓患者50例,隨機(jī)分成兩組。Ⅰ組(25例)采用右美托咪定復(fù)合七氟醚控制性降壓,Ⅱ組(25例)單純七氟醚麻醉控制性降壓。Ⅰ組于麻醉誘導(dǎo)前15min~20min靜脈泵注右美托咪定0.5μg/kg,以0.4μg/kg/h的濃度維持,誘導(dǎo)后開始調(diào)整七氟醚的吸入濃度,使平均動脈壓(MAP)控制在65mmHg左右并維持。Ⅱ組單純吸入七氟醚實施控制性降壓。觀察術(shù)中出血量,手術(shù)時間以及麻醉前(T1),手術(shù)開始后10min(T2)、手術(shù)開始后60min(T3)、手術(shù)結(jié)束拔管后即刻(T4)的MAP和心率(HR)變化。采用Fromme術(shù)野質(zhì)量評分法(SSFQ)評定術(shù)野質(zhì)量。Ⅰ組患者術(shù)中出血量、手術(shù)時間較Ⅱ組顯著減少(P0.05);Ⅰ組患者術(shù)中MAP、HR明顯低于術(shù)前(P0.05),兩組患者術(shù)野質(zhì)量明顯提高,SSFQ明顯降低(P0.05)。右美托咪定復(fù)合七氟醚控制性降壓用于鼻內(nèi)窺鏡手術(shù)高血壓患者,能有效減少出血量,改善手術(shù)野,縮短手術(shù)時間。
