摘要
目的:比较不同剂量右美托咪定复合舒芬太尼静脉自控镇痛(PCIA)对肺癌根治术后的镇痛效果。方法:选择80例择期行肺癌根治术患者,年龄43~65岁,ASAⅠ或Ⅱ级。按随机数字表分为4组(n=20):S组(舒芬太尼3μg/kg+氟比洛芬酯100 mg)、D1组[舒芬太尼3μg/kg+右美托咪定0.1μg/(kg·h)]、D2组[舒芬太尼3μg/kg+右美托咪定0.15μg/(kg·h)]、D3组[舒芬太尼3μg/kg+右美托咪定0.2μg/(kg·h)]。患者行静吸复合麻醉,于手术结束前30 min连接静脉镇痛泵。镇痛泵药液按上述四组药物配制,容量100 ml。输注设置:输注速率1.5 ml/h,单次按压给药量2 ml,锁定时间15 min,维持时间48 h。分别记录术后2、4、12、24、48 h的VAS疼痛评分、Ramsay镇静评分、平均动脉压(MBP)、心率(HR)、PCIA按压次数、不良反应情况。结果:四组患者在2~48 h各时点VAS评分比较差异无统计学意义;在2~48 h期间,D2和D3组Ramsay镇静评分明显高于S组(P<0.05),D2和D3组MBP明显低于S组(P<0.05),D3组HR明显低于S组(P<0.05);与S组比较,D2和D3组恶心呕吐发生率较低(P<0.05),D1组PCIA按压次数较多(P<0.05),D3组过度镇静和心动过缓发生率较高(P<0.05)。结论:右美托咪定[0.15μg/(kg·h)]复合舒芬太尼(3μg/kg)用于肺癌根治术能够获得完善镇痛效果,恶心呕吐发生率较低,血流动力学更稳定,未见显著心动过缓和过度镇静。
Objective： To observe the analgesia effects of different dose of dexmedetomidine combined with sufentanil for PCIA in patients undergoing lung cancer surgery. Methods： Eighty patients（ ASA grade Ⅰ or Ⅱ degree,aged43 - 65） undergoing lung cancer surgery were randomly assigned into four groups according to PCIA formulation（ n= 20）. Group S： Sufentanil 3 μg/kg ＋ flubiprofen 100 mg. Group D1： Dexmedetomidine 0. 1 μg/（ kg·h） ＋ sufentanil3 μg/kg. Group D2： Dexmedetomidine 0. 15 μg/（ kg·h） ＋ sufentanil 3 μg/kg. Group D3： Dexmedetomidine 0. 2 μg/（ kg·h） ＋ sufentanil 3 μg/kg. All patients received the same anesthesia method. Patients-controlled intravenous analgesia pump was applied 30 min before the end of surgery. The drugs were diluted to 100 ml with 0. 9% normal saline. Settings： Infusion speed 1. 5 ml/h. PCIA dosage 2 ml each time,lock time 15 min. VAS score,Ramsay score,MBP,HR,pressing times,side effects at 2,4,12,24,48 h after surgery were recorded. Results： There were no significant difference in VAS score at 2 - 48 h between four groups. The Ramsay score of group D2 and D3 was higher than group S at 2 - 48 h（ P＜0. 05）. The MBP of group D2 and D3 was lower than group S at 2 - 48 h（ P＜0. 05）. The HR of group D3 was lower than group S at 2 - 48 h（ P＜0. 05）. Compared with group S,the incidence of postoperative nausea and vomiting was lower in group D2 and D3（ P＜0. 05）.PCIA pressing times was more in group D1（ P＜0. 05）,and the incidence rate of hypersomnia and bradyrhythmia was higher in group D3. Conclusion： Dexmedetomidine[0. 15 μg/（ kg·h） ]combined with sufentanil（ 3 μg/kg） for PCIA after lung cancer surgery acquired satisfied analgesic effect,decreased the rate of vomiting and nausea without more hypersomnia and bradyrhythmia,and provided more stable hemodynamics.
