摘  要:目的 探讨地佐辛联合右美托咪定用于腹部手术患者术后自控镇痛(PCIA)的效果和安全性.方法 选择2014年3-11月解放军空军总医院拟行胃肠手术患者125例,按随机数字表法分为5组,各25例.A组给予地佐辛0.7 mg/kg;B组给予地佐辛0.7 mg/kg±右美托咪定1μg/kg;C组给予地佐辛0.7 mg/kg±右美托咪定2μg/kg;D组给予地佐辛1.0 mg/kg±右美托咪定1μg/kg;E组给予地佐辛1.0 mg/kg±右美托咪定2μg/kg.将药物加入0.9%氯化钠注射液中至总量为100 ml,同时加入格拉司琼9 mg,手术结束前30 min给予地佐辛负荷剂量5 mg±格拉司琼3 mg.镇痛泵设置为背景剂量2 ml/h,按压1次0.5 ml,按压后锁定时间15 min.记录并比较5组患者术后4、8、12、24和48 h的血压、心率、血氧饱和度、疼痛视觉模拟量表(VAS)评分、Ramsay镇静评分和不良反应发生情况.结果 A组术后各时点VAS评分均明显高于B、C、D、E组[4h:(4.36±0.66)分比(3.46±0.60)、(3.43±0.49)、(3.21±0.41)、(3.18±0.37)分;8 h:(4.32±0.62)分比(3.43±0.47)、(3.41±0.61)、(3.17±0.37)、(3.12±0.45)分;12 h:(4.47±0.48)分比(3.39±0.52)、(3.36±0.49)、(3.04±0.45)、(2.92±0.57)分;24 h:(4.39 ±0.50)分比(3.41±0.61)、(3.33±0.48)、(2.82±0.28)、(2.79±0.52)分;48 h:(4.36±0.51)分比(3.44±0.31)、(3.26±0.43)、(2.60±0.52)、(2.57 ±0.51)分;均P<0.01],D组和E组VAS评分均明显低于B组和C组(均P <0.05).A组术后各时点Ramasy镇静评分均明显低于B、C、D、E组[4 h:(1.5±0.5)分比(2.6±0.5)、(2.9±0.5)、(2.8±0.3)、(3.4±0.8)分;8 h:(1.6±0.5)分比(2.5±0.5)、(2.9±0.6)、(2.8±0.4)、(3.3±0.5)分;12 h:(1.6±0.6)分比(2.3±0.5)、(2.9±0.4)、(2.6±0.5)、(3.3±0.4)分;24 h:(1.7±0.5)分比(2.3±0.5)、(2.9±0.9)、(2.4±0.5)、(3.3±0.4)分;48 h:(1.7±0.3�Objective To explore the effect and safety of combined application of dezocine and dexmedetomidine (DEX) in patient controlled intravenous analgesia (PCIA) after abdominal surgery.Methods Totally 125 patients undergoing gastrointestinal surgery from March to November 2014 were randomly divided into group A administrated with dezocine (0.7 mg/kg), group B administrated with dezocine (0.7 mg/kg) ± DEX (1 μg/kg),group C administrated with dezocine (0.7 mg/kg) ± DEX (2 μg/kg), group D administrated with dezocine (1.0 mg/kg) ± DEX (1 μg/kg), and group E administrated with dezocine (1.0 mg/kg) ± DEX (2 pμg/kg).All the anesthetic agents were diluted into 100 ml of 0.9% sodium chloride, and 9 mg of granisetron was added additionally.A loading dose of dezocine (5 mg) and granisetron (3 mg) were infused intravenously 30 minutes before the end of operation.PCIA was fixed as background dose of 2 ml/h, dose of 0.5 ml/once and lock time of 15 min.The visual analog scale (VAS), Ramsay sedation scores, heart rate, blood pressure, surplus pulse O2 and the adverse effects were observed and compared among groups 4 h, 8 h, 12 h, 24 h and 48 h after operation.Results The VAS scores in group A at all the time point after operation were significantly higher than those of group B, C, D and E [4 h: (4.36±0.66) scores vs (3.46±0.60), (3.43 ±0.49), (3.21 ±0.41),(3.18±0.37) scores;8 h: (4.32 ±0.62) scores vs (3.43 ±0.47), (3.41 ±0.61), (3.17 ±0.37),(3.12±0.45) scores;12 h: (4.47 ±0.48) scores vs (3.39±0.52), (3.36 ±0.49), (3.04±0.45),(2.92±0.57) scores;24 h: (4.39 ±0.50) scores vs (3.41 ±0.61), (3.33 ±0.48), (2.82 ±0.28),(2.79±0.52) scores;48 h: (4.36±0.51) scores vs (3.44±0.31), (3.26±0.43), (2.60±0.52),(2.57 ±0.51) scores] (all P 〈0.01);the scores in group D and E were all lower than those in group B and C (P 〈 0.05).The Ramsay sco
