摘要
目的探讨右美托咪定(DEX)联合酮咯酸氨丁三醇对胸腔镜肺癌根治术术后患者的镇痛作用及其对免疫功能的影响。方法选择择期行胸腔镜肺癌根治手术患者60例,ASAⅠ~Ⅱ级,年龄18~65岁,患者采用随机数表分为舒芬太尼联合酮咯酸氨丁三醇组(SK组)和DEX联合酮咯酸氨丁三醇组(DK组),每组30例。术后使用静脉自控镇痛(PCIA),SK组给予舒芬太尼(0.04μg·kg-1·h-1)、酮咯酸氨丁三醇(3 mg/kg);DK组给予DEX (0.1μg·kg-1·h-1)、酮咯酸氨丁三醇(3 mg/kg)。镇痛时间48 h,负荷剂量2mL,背景输注速率2 mL/h,锁定时间20 min。记录2组麻醉诱导前(T0),PCIA后即刻(T1)、4 h (T2)、24 h (T3)、48 h (T4)生命体征、静息和活动后VAS评分、Ramsay镇静评分、PCIA按压总次数及有效次数、患者满意度和不良反应发生情况。于T0、T1、T3和T4时采集外周静脉血(2 mL),利用FACScaliber流式细胞仪检测T细胞亚群CD3+、CD4+、CD8+的含量以及NK细胞含量,计算CD4+/CD8+比值。结果与T0时比较,SK组在T1、T2、T3时心率显著升高(P <0.05),在T3、T4时收缩压降低(P <0.05);DK组在T2、T3、T4时心率显著降低(P <0.05),在T1、T2、T3、T4时收缩压和舒张压显著降低(P <0.05)。与SK组比较,DK组在T2、T3、T4时心率、收缩压和舒张压显著降低(P <0.05)。DK组静息状态T1、T2、T3、T4时VAS评分,活动后T1、T2时VAS评分较SK组略高(P <0.05),但2组患者术后不同时间静息VAS评分均<3分,活动后VAS评分仅在T4时>3分,镇痛效果良好。DK组患者满意度明显高于SK组(P <0.05)。2组患者术后均无镇静过度、呼吸抑制、皮肤瘙痒、消化道出血等并发症;恶心呕吐发生率DK组明显低于SK组(P <0.05)。与T0时比较SK组T1、T3、T4时CD3+、CD4+、CD4+/CD8+以及NK细胞水平降低(P <0.05);DK组T1、T3、T4时CD4+、CD4+/CD8+以及NK细胞水平降低(P <0.05)。DK组T3、T4时CD4+、CD4+/CD8+细胞水平较SK组明显升高(P <0.05)。结论 DEX联合酮咯酸氨丁三醇
Objective To investigate the effects of dexmedetomidine-ketorolac combinations on postoperative pain and immunity in patients undergoing thoracoscopic radical resection of lung cancer.Methods Sixty patients(ASAⅠ-Ⅱ)scheduled for thoracoscopic radical resection of lung cancers were recruited and divided into two groups,to be administered(1)sufentanil 0.04μg·kg-1·h-1+ketorolac 3 mg/kg(SK group,n=30)or(2)dexmedetomidine 0.1μg·kg-1·h-1+ketorolac 3 mg/kg(DK group,n=30)for postoperative patient-controlled infusion analgesia(PCIA).Vital signs;visual analogue scale(VAS)of pain;Ramsay sedation scale before anesthesia induction(T0)and at 0 h(T1),4 h(T2),24 h(T3),and 48 h(T4)after PCIA;total and effective button pressing attempts during PCIA;patient satisfaction scores;and side effects were compared between the two groups.Levels of immune cells were also compared.Results In the DK group,hemodynamics were more stable(P<0.05).VAS scores at rest at T1,T2,T3,and T4,and VAS scores after movement at T1 and T2,and patient satisfaction scores in the DK group were relatively higher than those in the SK group(P<0.05).Incidence of nausea and vomiting were lower in the DK group than in the SK group(P<0.05).Levels of CD3+,CD4+,CD4+/CD8+,and NK cells decreased significantly in anathe SK group,while levels of CD4+,CD4+/CD8+,and NK cells decreased significantly in the DK group after surgery(P<0.05).Levels of CD4+,and CD4+/CD8+cells were higher in the DK group than in the SK group(P<0.05).Conclusion Combined use of dexmedetomidine and ketorolac in PCIA can provide safe and effective analgesia,reduce opioid-related side effects,and improve the postoperative immunity of patients undergoing thoracoscopic radical resection of lung cancer.
