Randomized Controlled Trial
[The Effect of Preoperative Oral Rehydration on Hemodynamic Changes during Induction of Anesthesia and Intraoperative Fluid Management].
Preoperative oral rehydration solution (ORS) prevents dehydration before surgery. Therefore taking enough ORS possibly reduces the hemodynamic changes during induction of anesthesia, and reduces the amount of fluid needed during anesthesia. ⋯ Preoperative oral rehydration increases circulating blood volume, it keeps high CI during induction of anesthesia, and reduces the amount of intraoperative fluid.
