帕瑞昔布钠用于肺叶切除术病人超前镇痛的效果

目的 评价帕瑞昔布钠用于肺叶切除术病人超前镇痛的效果.方法 择期行开胸肺叶切除术病人60例,性别不限,年龄20～64岁,体重50～80 kg,ASA分级Ⅱ或Ⅲ级,采用随机数字表法,将患者随机分为3组(n=20):对照组(C组)不给予帕瑞昔布钠；帕瑞昔布钠超前镇痛组(A组)于术前20 min静脉注射帕瑞昔布钠40 mg;帕瑞昔布钠组(B组)于缝皮时静脉注射帕瑞昔布钠40 mg.术后行自控静脉镇痛(舒芬太尼2μg/kg和盐酸雷莫司琼0.6 mg加生理盐水至100 ml,镇痛泵负荷剂量10 ml,持续背景剂量2ml/h,PCA量0.5ml,锁定时间15 min),VAS评分＞3分时静脉注射曲马多1～2mg/kg.记录术后躁动发生情况,记录术后24h内镇痛泵按压次数、有效按压次数、舒芬太尼用量及补救用药使用情况.结果 与C组比较,A组和B组术后躁动发生率降低,术后24h内镇痛泵按压次数、有效按压次数、舒芬太尼消耗量和补救用药使用率降低(P＜0.05)；与B组比较,A组术后24h内镇痛泵按压次数、有效按压次数、舒芬太尼消耗量和补救用药使用率降低(P＜0.05).结论 帕瑞昔布钠用于肺叶切除术病人具有超前镇痛作用,有助于降低麻醉恢复期并发症,产生阿片类镇痛药的节俭作用.

Efficacy of preemptive analgesia with parecoxib for acute postoperative pain after pulmonary lobectomy

Objective To evaluate the efficacy of preemptive analgesia with parecoxib for acute postoperative pain after pulmenary lobectomy.Methods Sixty ASA Ⅱ or Ⅲ patients of both sexes aged 20-64 yr weighing 50-80 kg undergoing elective pulmonary lobectomy were randomly divided into 3 groups ( n =20 each): control group (group C); group A (parecoxib 40 mg was injected iv at 20 min before surgery) and group B (parecoxib 40 mg was injected iv when skin was sutured).Patient controlled intravenous analgesia (PCIA) with sufentanil and ramosetron (continuous background dose 2 ml/h,bolus dose 0.5 ml,lockout time 15 min) was used after surgery.When VAS score ＞ 3,iv bolus of tramadol 1-2 mg/kg was injected as rescue medicine.Agitation condition was observed after operation.The number of successfully delivered doses and the number of attempt were recorded.The consumption sufentanil and the number of rescue medicine were recorded during 24 h after surgery.Results The incidence of postoperation agitation,number of successfully delivered doses and number of attempt,consumption sufentanil and number of rescue medicine were significantly lower in groups A and B than in group C.The consumption sufentanil and number of rescue medicine were significantly lower in group A than in group B ( P ＜0.05).Conclusion Parecoxib can use for preemptive analgesia in patients after thoracic surgery,reduce the complication during anesthesia recovery and the opioid analgesics consupmtion.
