高乌甲素对患者围术期免疫功能的影响

目的 探讨高乌甲素对患者围术期免疫功能的影响.方法 择期行乳腺癌根治术、椎管狭窄椎板切除减压术、人工股骨头置换术患者各8例,随机分为2组(n=12):对照组(C组)和高乌甲素组(L组).L组麻醉诱导前30 min经30 min静脉输注高乌甲素8 mg,静脉注射恩丹西酮4 mg;C组给予等容量生理盐水.2组采用异丙酚、瑞芬太尼和罗库溴铵进行麻醉诱导和维持.诱导开始后L组持续背景输注0.28 mg/ml高乌甲素2 ml/h.术毕待患者清醒后,L组采用0.28 mg/ml高乌甲素行病人自控镇痛(PCA),背景输注速率2 ml/h,PCA剂量0.5 ml,锁定时间15 min.C组术后镇痛采用按需单次肌肉注射哌替啶50 mg和氟哌利多2.5 mg.于麻醉诱导前30 min(T1)、术毕(T2)、术后24 h(T3)和48 h(T4)时采集外周静脉血样,采用ELISA法测定TNF-α、IL-2、IFN-γ和sIL-6R浓度;采用流式细胞仪测定CD3、CIM、CD8和NK细胞表达,计算CD4/CD8;采用放射免疫法测定IgA、IgM、IgG、C3和C4浓度.结果 与C组比较,L组T2-4时sIL-6R浓度降低,T3-4时INF-α浓度降低,IL-2和IgA浓度升高,T2,3时IgG浓度升高,T3时IgM浓度和CD4/CD8升高(P＜0.05或0.01).结论 高乌甲素可改善患者围术期体液免疫功能,可能与其镇痛和抗炎作用有关.

Effect of lappaconitine on perioperative immune function

Objective To investigate the effects of lappaconitine on the perioperative immune function.Methods Twenty-four ASA I or II patients aged 23-64 yr undergoing elective radical mastectomy (8 patients),iaminectomy and vertebral canal decompression (8 patients) or femoral head replacement (8 patients ) were randomly divided into 2 groups (n=12 each): control group (C) and lappaconitine group (L).In group L ondansetron 4 mg was given IV and lappaconitine 8 mg was infused IV over 30 rain before induction of anesthesia.In group C equal volume of normal saline was infused instead of lappaconitine.Anesthesia was induced and maintained with propofol,remifentanil and rocuronium.Lappaconitine 0.28 mg/ml was continuously infused at 2 ml/h after induction of anesthesia in group L.When the patients recovered from anesthesia after operation,PCA with 0.28 mg/ml lappaconitine was started (background infusion 2 ml/h,bolus dose 0.5 ml and lockout interval 15 min).In group C pethidine 50 mg and droperidol 2.5 mg were given IM on demand.Venous blood samples were taken at 30 rain before induction of anesthesia(T1,baseline),immediately (T2) and at 24 h(T3) and 48 h (T4)after operation for determination of TNF-α,IL-2,IFN-γ and sIL-6R concentration by ELISA.CD3,CD4,CD8 and NK cell expression was determined using flow cytometry and the ratio of CD4/CD8 was calculated.The concentrations of IgA,IgM,IgG,CD3 and CD4 were determined by radioimmunoassay.Results Plasma SIL-6R and TNF-α concentrations were significantly lower while IL-2,IgA,IgG,IgM concentrations and CD4/CD8 ratio were significantly higher after operation in group L than in group C.Conclusion Lappaconitine can improve perioperafive humoral immune function thus contributing to its analgesic and anfi-inflammatory effects.
