RT Journal Article SR Electronic T1 Hazards of postoperative fluid therapy JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 47 OP 48 DO 10.1136/dtb.10.12.47 VO 10 IS 12 YR 1972 UL http://dtb.bmj.com/content/10/12/47.abstract AB Oral feeding is often undesirable after major surgery, and fluid and electrolyte intake then has to be maintained intravenously. Problems in the postoperative management may occur because surgery itself interferes with the homeostatic regulation of fluid and electrolyte balance, or because a standard fluid replacement schedule is used without regard to the particular needs of the patient.
