[Differences in Postoperative Metabolism After Pre- and Postoperative Beginning of Total Parenteral Nutrition]
Overview
Affiliations
In this study we intended to investigate the influence of a 24-h-preoperative total parenteral nutrition (TPN) therapy--10 surgical patients, group 1--compared with the postoperative beginning of TPN--9 surgical patients, group 2--on the postoperative metabolism. Most probably due to preoperatively depleted glycogen storages in G 2, the urinary carbohydrate losses declined more rapidly postoperatively compared with G 1. 45 mMol/l of sodium did not cover the postoperative requirements of G 1. Although we administered 90 mMol/l of potassium/24 h, several patients of G 1 needed an additional substitution. No additional phosphate substitution was necessary in either group. Except for a slight positive balance on the operation day, fluid balance was well balanced on all the other days in G 1. From postoperative day 2 on, G 2 developed a deficit of free water. It could be demonstrated very clear in this study that the postoperative fluid and electrolyte requirements are strongly influenced even by a short-term preoperative fasting period.
