A consensus as to whether hypertonic dextrose should be given to patients with chronic liver diseases such as cirrhosis or chronic hepatitis after major hepatectomy has not been reached, mostly because metabolism in the remnant liver switches from utilization of blood glucose to utilization predominantly of fatty acid as an energy source. We investigated whether nutritional support would have beneficial effects for such patients.
Among 19 patients, 10 were given peripheral dextrose (10 kcal/kg/day) for seven days following hepatectomy and the other 9 were given hypertonic glucose. Twenty and 30 kcal/kg/day was the average non-protein caloric intake, including free oral intake during the first one week following hepatectomy, respectively.
The groups were comparable with regard to laboratory data and operative stress. There were no untoward effects related to this support. In patients given nutritional support, retinol binding protein and prealbumin improved (p < 0.05 and p < 0.05, respectively), urinary 3-methylhistidine excretion decreased (p < 0.01) and the nitrogen balance normalized earlier (p < 0.05), as compared to findings with the conventional method.
The remnant liver can utilize dextrose and nutritional support improves the nutritional status and may even preserve muscle protein mass.
对于在肝大部切除术后是否应给予肝硬化或慢性肝炎等慢性肝病患者高渗葡萄糖,尚未达成共识,主要原因是残余肝脏的代谢从利用血糖转变为主要利用脂肪酸作为能量来源。我们研究了营养支持对此类患者是否有有益作用。
19例患者中,10例在肝切除术后接受外周葡萄糖(10千卡/千克/天)输注7天,另外9例接受高渗葡萄糖输注。肝切除术后第一周,分别包括自由口服摄入量,平均非蛋白热量摄入为20和30千卡/千克/天。
两组在实验室数据和手术应激方面具有可比性。这种支持未产生不良影响。与传统方法相比,接受营养支持的患者视黄醇结合蛋白和前白蛋白水平有所改善(分别为p < 0.05和p < 0.05),尿3 - 甲基组氨酸排泄减少(p < 0.01),氮平衡更早恢复正常(p < 0.05)。
残余肝脏能够利用葡萄糖,营养支持可改善营养状况,甚至可能保留肌肉蛋白量。
