【摘要】:目的評價右美托咪定復合羅哌卡因用于骶管麻醉在會陰部手術中應用的效果。方法擇期擬行會陰部手術患者60例,性別不限,年齡20~65歲,體重50~80 kg,ASA分級Ⅰ~Ⅱ級,采用隨機數(shù)字表法分為3組(n=20):羅哌卡因骶管阻滯組(R組),右美托咪定復合羅哌卡因骶管阻滯組(DR組),羅哌卡因骶管阻滯復合靜脈輸注右美托咪定組(CR組)。3組均在超聲引導下行骶管麻醉,R組和CR組均注入0.5%羅哌卡因30 m L,DR組注入含1μg/kg右美托咪定復合0.5%羅哌卡因30 m L,CR組手術開始前15 min靜脈輸注右美托咪定1μg/kg。記錄感覺阻滯起效時間,阻滯平面和感覺阻滯持續(xù)時間。于術后30 min、120 min、6 h、12 h、18 h、24 h記錄疼痛數(shù)字評分法(NRS)評分并記錄手術結束后30 min的Ramsay評分,記錄血流動力學變化和呼吸抑制的發(fā)生情況,術后2 h內(nèi)麻醉相關不良事件發(fā)生情況。結果與R組比較,CR組、DR組感覺阻滯起效時間明顯縮短(P0.05),術后鎮(zhèn)痛時間明顯延長(P0.05,P0.01)。與CR組相比,DR組感覺阻滯起效時間縮短,術后鎮(zhèn)痛時間延長(P0.05);3組阻滯平面及術后30 min的Ramsay評分差異無統(tǒng)計學意義。與R組相比,CR組患者術后6~18 h NRS評分明顯降低(P0.05),術后24 h的NRS評分差異無統(tǒng)計學意義(P0.05);與R組及CR組同時點相比,DR組患者術后24 h內(nèi)NRS評分均明顯降低,比較差異有統(tǒng)計學意義(P0.05,P0.01)。R組及DR組均未見麻醉相關不良事件發(fā)生,CR組有3例出現(xiàn)心動過緩,給予阿托品處理后好轉。結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。
