【摘要】:目的:本研究旨在探討小劑量右美托咪定(Dexrnedetomidine,Dex)復(fù)合靶控輸注(Traget controlled infusin,TCI)三種不同預(yù)設(shè)血漿濃度異丙酚用于肥胖患者無痛腸鏡檢查術(shù)的麻醉效果及安全性,尋求一個(gè)適宜肥胖患者的方案。方法:行無痛腸鏡檢查術(shù)的患者90例,性別不限,美國麻醉評(píng)分(American Society of Anesthesiolgist,ASA)Ⅰ級(jí)或Ⅱ級(jí),年齡30~50歲,BMI 28~32 kg/m2,采用隨機(jī)數(shù)字表法,將患者隨機(jī)分為:生理鹽水對(duì)照組(P組,n=45)和Dex組(DP組,n=45),麻醉前15 min DP組靜脈注射Dex負(fù)荷劑量0.3μg/kg,10min注射完,隨后復(fù)合TCI異丙酚按預(yù)設(shè)血漿靶濃度2,3,4μg/ml分為DP1,DP2,DP33個(gè)亞組(n=15),P組麻醉前給予等容量生理鹽水,麻醉時(shí)按TCI異丙酚預(yù)設(shè)血漿靶濃度2,3,4μg/ml分為P1,P2,P3 3個(gè)亞組(n=15),觀察記錄術(shù)前(T0)、用Dex或安慰劑后第10min(T1)、用異丙酚意識(shí)消失后(T2)、檢查開始1min(T3)、檢查開始5min(T4)、檢查結(jié)束時(shí)(T5)、喚醒時(shí)(T6)7個(gè)時(shí)間點(diǎn),記錄腦電雙頻指數(shù)(Bisperctra in dex,BIS)、平均動(dòng)脈壓(Mean arterial pressure,MAP)、心率(Heart rate,HR)、呼吸頻率(Respiratory rate,RR)和脈搏血氧飽和度(Pulse blood oxygen saturation,SPO2)。并觀察體動(dòng)、心動(dòng)過緩、低血壓、呼吸抑制、低氧血癥、惡心嘔吐、反流誤吸、嗆咳、術(shù)中知曉等不良反應(yīng),記錄蘇醒質(zhì)量以及離院評(píng)分情況。結(jié)果:與P1組相比,DP1組無需追加異丙酚、血流動(dòng)力學(xué)更穩(wěn)定,無呼吸抑制發(fā)生,無體動(dòng)反應(yīng),蘇醒質(zhì)量好以及離院評(píng)分高(P0.05)。與DP2和DP3組相比,DP1組異丙酚用量最小,血流動(dòng)力學(xué)更穩(wěn)定,無呼吸抑制發(fā)生,蘇醒質(zhì)量高,離院評(píng)分高(P0.05)。單純使用異丙酚組(P1—3)出現(xiàn)嗆咳,而使用Dex各組(DP1—3)均未出現(xiàn)嗆咳(P㩳0.05,差異有統(tǒng)計(jì)意義)。各組均無惡心嘔吐、反流誤吸和術(shù)中知曉等不良反應(yīng)。結(jié)論:在維持一定的麻醉深度前提下,Dex(負(fù)荷劑量0.3μg/kg)復(fù)合TCI異丙酚(預(yù)設(shè)血漿靶濃度為2μg/ml),對(duì)于肥胖患者無痛腸鏡檢查麻醉效果確切安全。
