外科病人的胃肠外营养

Parenteral nutrition (PN) for surgical patients

在医治伴有胃肠功能衰竭或胃肠道不能使用的外科病人时,胃肠外营养是很有用的辅助手段.在病程的早期开始应用胃肠外营养比晚期开始好.然而,应避免过多的营养素输入,因为许多代谢性并发症可能因此而发生,危重病人的病情也不会仅仅因为输入过多的营养素而有所改善.

PN is an useful adjunct in the care of surgical patients who have gastrointestinal failure of whose gastrointestinal tract is not readily available. PN should be started early rather than late in the course of the patients illness. However, infusion of an excessive amount of nutrients should be avoided since many metabolic complications may be precipitated. Critically ill patients will not be improved solely by the overzealous administration of excessive nutrients.
