The fluid-therapy as a postoperative care is important in the geriatric surgery because of the weak response of their body function physiologically.
On the determination of body fluid distribution, the decrease of total body water and the relative increase of extracellular fluid volume were observed especially in hypoproteinemic and dehydrated poor risk aged patients.
The influence of bleeding during surgery was noticeable in the aged patients, was found in much severe grade than that of the younger.
During postoperative course, the body weight of aged patients who had subtotal gastrec tomy, gradually decreased until the 4th or 5th postoperative day, and then slowly increased, The primary water balance declined to more positive than that of younger adults, The extracellular fluid remained in high level and the decrease of circulating plasma volume was much more than that of the younger. The salt balance declined to positive especially in the immediate postoperative days. Generally, the fluid volume given postoperatively in the aged should be a little smaller amount compared with that of the younger. Also the dosis of salt given, should be withheld within 2 or 3g per day.
