【摘要】：目的評(píng)價(jià)小劑量羅哌卡因復(fù)合右美托咪定蛛網(wǎng)膜下腔麻醉在肛門直腸手術(shù)中的應(yīng)用效果。方法擇期行肛門直腸手術(shù)患者60例,ASA分級(jí)Ⅰ或Ⅱ級(jí),采用隨機(jī)數(shù)字表法分為R組、RD1組、RD2組,分別采用0.5%羅哌卡因6 mg、0.5%羅哌卡因6 mg+右美托咪定3μg、0.3%羅哌卡因6 mg+右美托咪定3μg進(jìn)行蛛網(wǎng)膜下腔麻醉。記錄感覺(jué)阻滯起效時(shí)間、運(yùn)動(dòng)阻滯起效時(shí)間、感覺(jué)阻滯持續(xù)時(shí)間、運(yùn)動(dòng)阻滯持續(xù)時(shí)間、最高感覺(jué)阻滯平面;采用針刺法評(píng)價(jià)三組的麻醉效果;記錄低血壓、心動(dòng)過(guò)緩、惡心嘔吐、尿潴留和頭痛等不良反應(yīng)的發(fā)生情況。結(jié)果與R組、RD1組比較,RD2組運(yùn)動(dòng)阻滯持續(xù)時(shí)間縮短,Bromage評(píng)分降低(P均0.05);RD1組最高感覺(jué)阻滯平面高于其余兩組,RD1、RD2組運(yùn)動(dòng)阻滯起效時(shí)間短于R組(P均0.05);三組感覺(jué)阻滯起效時(shí)間、麻醉效果及不良反應(yīng)發(fā)生率比較,P均0.05。結(jié)論 0.3%羅哌卡因6 mg復(fù)合右美托咪定3μg蛛網(wǎng)膜下腔麻醉能滿足肛門直腸手術(shù)要求。術(shù)后患者下肢運(yùn)動(dòng)恢復(fù)早,血流動(dòng)力學(xué)穩(wěn)定,不良反應(yīng)發(fā)生率低。
