长期以来,在创伤外科营养中,都用葡萄糖作为热能的载体,但是人体在应激状况下,葡萄糖代谢往往会出现障碍,这给葡萄糖输入造成了许多的困难,解决术后热能供给问题已成了术后静脉营养的中心研究课题之一。虽然有人曾经提出用等渗葡萄糖溶液,以克服葡萄糖输液的缺点,但热量太少,不能满足患者的热能需求,不能有效地防止内源性蛋白质的消耗。当输给高渗葡萄糖溶液时,虽然热能提高了,但付作用太大,有人提出在葡萄糖溶液中加入胰岛素,以克服上述付作用,但也存在不少问题。
For a long time, in traumatic surgical nutrition, glucose has been used as a carrier of thermal energy. However, under stress conditions, glucose metabolism is often impaired. This poses many difficulties for glucose input. The solution to postoperative thermal energy supply has become One of the central research topics of postoperative intravenous nutrition. Although it has been proposed to use isotonic glucose solution to overcome the shortcomings of glucose infusion, but too little heat, can not meet the patient’s thermal energy needs, can not effectively prevent the consumption of endogenous protein. When fed to hypertonic glucose solution, although the thermal energy increased, but pay too much effect, it was proposed to add insulin in glucose solution to overcome the above-mentioned role, but there are also many problems.
