右美托咪啶与咪达唑仑复合舒芬太尼用于肝癌微波治疗术患者麻醉效果的比较

目的 比较右美托咪啶与咪达唑仑复合舒芬太尼用于肝癌微波治疗术患者麻醉的效果.方法 择期行经皮肝穿刺微波治疗术的肝癌患者40例,男性,ASA分级Ⅱ级,年龄35～62岁,体重45～70 kg,采用随机数字表法,将其随机分为2组(n=20):咪达唑仑组(Ⅰ组)和右美托咪啶组(Ⅱ组).Ⅰ组静脉注射咪达唑仑负荷量40μg/kg,然后静脉输注咪达唑仑40μg·kg-1·h-1;Ⅱ组静脉注射右美托眯啶负荷量1μg/kg,然后静脉输注右美托咪啶0.5μg·kg-1·h-1.两组药物负荷量均用生理盐水稀释至20ml,注射时间均为10 min.负荷量注射完毕后5 min时,静脉注射舒芬太尼负荷量0.2μg/kg,然后采用舒芬太尼行PCIA,背景输注速率0.1μg·kg-1·h-1,PCA量0.1μg/kg,锁定时间3 min.舒芬太尼负荷量注射完毕后2 min开始手术.记录术中心动过缓、心动过速、低血压、高血压和呼吸抑制的发生情况;记录舒芬太尼的PCA总按压次数和有效按压次数.结果 两组心动过缓、心动过速、低血压和高血压的发生率比较差异无统计学意义(P＞0.05);与Ⅰ组比较,Ⅱ组呼吸抑制发生率降低,舒芬太尼PCA总按压次数和有效按压次数减少(P＜0.05).结论 肝癌微波治疗术患者右美托咪啶复合舒芬太尼的麻醉效果优于咪达唑仑复合舒芬太尼.

Abstract：

Objective To compare the efficacy of anesthesia with dexmedetomidinc and midazolam combined with sufentanil in patients undergoing microwave coagulation therapy for liver cancer. Methods Forty ASA Ⅱ male patients, aged 35-62 yr, weighing 45-70 kg, scheduled for percutaneous microwave coagulation therapy,were randomly divided into 2 groups ( n = 20 each): midasolam group ( group Ⅰ ) and dexmedetomidine group ( group Ⅱ ). A loading dose of midazolam 40 μg/kg ( in normal saline 20 ml) was given intravenously over 10 min,followed by midasolam infusion at 40 μg·kg-1 ·h-1 in group Ⅰ . A loading dose of dexmedetomidine 1 μg/kg (in normal saline 20 ml ) was given intravenously over 10 min, followed by dexmedetomidine infusion at 0.5 loading dose of sufentanil 0.2 μg/kg was given, and then patient-controlled intravenous anesthesia with sufentsnil (background infusion 0.1 μg·kg-1 ·h-1 , bolus dose 0.1 μg/kg, lockout interval 3 min) was used. The operation was started 2 min after administration of the loading dose of sufentanil. Bradycardia, tachycardia, hypotension, hypertensinn and respiratory depression were recorded. The number of attempts and successfully delivered doses was also recorded. Results There was no significant difference in the incidence of bradycardia, tachycardia, hypotension and hypertension between the two groups ( P ＞ 0 .05). The incidence of respiratory depression was significantly lower, and the number of attempts and successfully delivered doses was smaller in group Ⅱ than in group Ⅰ ( P ＜ 0.05). Conclusion The efficacy of anesthesia with dexmedetomidine and sufentanil is better than that of anesthesia with midazolam and sufentanil in patients undergoing microwave coagulation therapy for liver cancer.
