title: A randomised comparison of two postoperative fluid regimens.
abstract: Postoperative paralytic ileus follows all significant gastrointestinal surgery. Its duration is variable and has led to a variety of empirical and time-consuming oral fluid regimens. We have compared a traditional method of fluid administration with an unstructured, simpler, patient-determined approach. A series of 102 patients on a general surgical ward who required intravenous fluids on the day after surgery were randomised by a closed envelope system to one of two protocols and followed prospectively. Of these, 12 patients were erroneously randomised or unable to fulfil trial requirements. The first, 'regulated' group (n = 41) received hourly aliquots of oral fluid as determined by twice daily ward rounds according to ward routine. The second, 'unregulated' group (n = 49) were given a jug of water and instructed to drink as desired. Patients in the regulated group received less of their postoperative fluids by the oral route at all stages of recovery but there were no significant differences in the mean durations of intravenous therapy, nasogastric intubation or hospital stay. Postoperative complication and mortality rates were also similar. Patients who underwent gastric or duodenal procedures (n = 14) showed a similar pattern of results. We conclude that 'patient-determined' regulation of postoperative oral fluid intake is safe and effective and may greatly simplify ward management.
