不同赋形剂异丙酚对患者肝移植术中血脂及肝功能的影响

目的 探讨不同赋形剂异丙酚对患者肝移植术中血脂及肝功能的影响.方法 择期拟行经典式非转流原位肝移植术患者40例,年龄40～64岁,体重50～75 kg,ASA分级Ⅲ或Ⅳ级,采用随机数字表法,将患者随机分为2组(n=20):异丙酚中/长链甘油三酯注射液组(M组)和异丙酚长链甘油三酯注射液组(L组).麻醉诱导:静脉注射盐酸戊乙奎醚1 mg、眯达唑仑0.04～0.06 mg/kg,舒芬太尼0.6～0.8μg/kg和维库溴铵0.10～0.15mg/kg,M组和L组分别静脉注射不同赋形剂的异丙酚1.5～2.0 mg/kg,气管插管后行机械通气.麻醉维持:吸入1%～2%异氟醚、M组和L组分别静脉输注不同赋形剂的异丙酚3～4 mg·kg-1·h-1和顺阿曲库铵0.2～0.3 mg·kg-1·h-1,间断静脉注射舒芬太尼0.2～0.3μg/kg.于入室(T1)、切皮前(T2)、无肝前期末(T3)、无肝期末(T4)、新肝期30 min(T5)、240 min(T6)时采集静脉血样,测定血浆甘油三酯(TG)、总胆固醇(CH)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)浓度及AST、ALT活性,并计算各指标的相对基线变化值.结果 与L组比较,M组T4-6时△TG降低(P＜0.05),△CH、△HDL-C、LDL-C、△AST、△ALT差异无统计学意义(P＞0.05).两组间血浆TG、CH、HDL-C、LDL-C浓度、AST和ALT活性比较差异无统计学意义(P＞0.05).结论 异丙酚中/长链甘油三酯注射液和异丙酚长链甘油三酯注射液虽然对肝功能影响无差异,但异丙酚中/长链甘油三酯注射液对血脂影响小,更有益于肝移植术患者.

Abstract：

Objective To investigate the effect of different excipients of propofol on blood lipids and liver function during orthotopic liver transplantation. Methods Forty ASA Ⅲ- Ⅳ patients aged 40-64 yr weighing 50-75 kg undergoing orthotopic liver transplantation were randomly divided into 2 groups ( n = 20 each): propofol medium-chain triglycerides/long-chain triglycerides (MCT/LCT) group (group M) and propofol LCT group (group L). Anesthesia was induced with penehyclidine 1 mg, midazolam 0.04-0.06 mg/kg, sufentanil 0.6-0.8 μg/kg and propofol 1.5-2.0 mg/kg. Tracheal intubation was facilitated with vecuronium 0.10-0.15 mg/kg. The patients were mechanically ventilated. Anesthesia was maintained with 1%-2% isoflurane, continuous infusion of propofol blood samples were collected after admission into the operation room (T1), before skin incision (T2), at the end of pre-anhepatic phase (T3), at the end of anhepatic phase (T4) and 30 and 240 min of neohepatic phase (T5, T6 )for determination of plasma concentrations of triglyceride (TG), total cholesterol (CH), high-density-lipoproteincholesterol (HDL-C), low density-lipoprotein-cholesterol (LDL-C), and activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The changes in parameters from baseline values were calculated. Results Compared with group L, △TG was significant1y decreased at T4-6 in group M ( P ＜ 0.05 ) . There was no significant difference in △CH, △HDL-C, △LDL-C, △AST and △ALT,plasma concentrations of TG,CH, HDL-C and LDL-C,and activities of AST and ALT between the two groups ( P ＞ 0.05). Conclusion The effect of the two formulations of propofol on liver function is comparable. Propofol MCT/LCT exerts less effect on blood lipids during liver transplantation and is more suitable for this type of surgery.
