Background and aim：The efficacy and safety of preoperative oral rehydration therapy（ORT）were investigated in hemodialysis patients with a narrow safety margin of fluid and electrolyte intake and a risk of delayed gastric emptying.
Methods：Two hundred patients receiving hemodialysis and undergoing general surgical operations were divided into ORT and infusion groups. In the ORT group, clear fluid was orally administered until 180 min prior to anesthesia instead of routine drip infusion. Serum electrolyte and blood sugar levels, the pyloric cross-sectional area, and gastric juice volume were measured before anesthesia induction. Postoperative weight gain was also evaluated as a fluid balance index.
Results：The ORT group had higher levels of fluid intake, electrolytes, and glucose than the infusion group. There were significantly fewer patients presenting with hyponatremia or hyperglycemia in the ORT group. Serum electrolyte and blood sugar levels were more favorable in the ORT group. No significant difference was found in postoperative weight gain among the two groups, suggesting that preoperative ORT did not result in fluid overload. No significant differences were noted in the pyloric cross-sectional area or gastric juice volume.
Conclusion：ORT is useful and safe for preoperative fluid management of hemodialysis patients.
