【摘要】:目的評(píng)價(jià)右美托咪定復(fù)合羅哌卡因用于骶管麻醉在會(huì)陰部手術(shù)中應(yīng)用的效果。方法擇期擬行會(huì)陰部手術(shù)患者60例,性別不限,年齡20~65歲,體重50~80 kg,ASA分級(jí)Ⅰ~Ⅱ級(jí),采用隨機(jī)數(shù)字表法分為3組(n=20):羅哌卡因骶管阻滯組(R組),右美托咪定復(fù)合羅哌卡因骶管阻滯組(DR組),羅哌卡因骶管阻滯復(fù)合靜脈輸注右美托咪定組(CR組)。3組均在超聲引導(dǎo)下行骶管麻醉,R組和CR組均注入0.5%羅哌卡因30 m L,DR組注入含1μg/kg右美托咪定復(fù)合0.5%羅哌卡因30 m L,CR組手術(shù)開始前15 min靜脈輸注右美托咪定1μg/kg。記錄感覺(jué)阻滯起效時(shí)間,阻滯平面和感覺(jué)阻滯持續(xù)時(shí)間。于術(shù)后30 min、120 min、6 h、12 h、18 h、24 h記錄疼痛數(shù)字評(píng)分法(NRS)評(píng)分并記錄手術(shù)結(jié)束后30 min的Ramsay評(píng)分,記錄血流動(dòng)力學(xué)變化和呼吸抑制的發(fā)生情況,術(shù)后2 h內(nèi)麻醉相關(guān)不良事件發(fā)生情況。結(jié)果與R組比較,CR組、DR組感覺(jué)阻滯起效時(shí)間明顯縮短(P0.05),術(shù)后鎮(zhèn)痛時(shí)間明顯延長(zhǎng)(P0.05,P0.01)。與CR組相比,DR組感覺(jué)阻滯起效時(shí)間縮短,術(shù)后鎮(zhèn)痛時(shí)間延長(zhǎng)(P0.05);3組阻滯平面及術(shù)后30 min的Ramsay評(píng)分差異無(wú)統(tǒng)計(jì)學(xué)意義。與R組相比,CR組患者術(shù)后6~18 h NRS評(píng)分明顯降低(P0.05),術(shù)后24 h的NRS評(píng)分差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);與R組及CR組同時(shí)點(diǎn)相比,DR組患者術(shù)后24 h內(nèi)NRS評(píng)分均明顯降低,比較差異有統(tǒng)計(jì)學(xué)意義(P0.05,P0.01)。R組及DR組均未見麻醉相關(guān)不良事件發(fā)生,CR組有3例出現(xiàn)心動(dòng)過(guò)緩,給予阿托品處理后好轉(zhuǎn)。結(jié)論右美托咪定靜脈注射及椎管內(nèi)用藥均可優(yōu)化羅哌卡因骶管麻醉效果,但椎管內(nèi)用藥的麻醉優(yōu)化效果更為顯著。
