Perioperative water balance in patients with acute abdominal pathology in a liberal regime of infusion therapy

In order to evaluate the effectiveness of the liberal regime of infusion therapy, we examined 50 patients with acute abdominal pathology considering the state of the water sectors of the body. We established that liberal regime of infusion causes hypervolemia and hyperhydration of peripheral tissues during the first 6 hours of the perioperative period, it retains a moderate deficit of hypovolemia and dehydratation from 1 to 14 day of observation and forms an increase in interstanial volume, causing its maximum edema from the 3d to 7th day of observation. These changes are combined with positive daily and cumulative water balances, which is reflected in a critical increase in the percentage of excess fluid from the 5th day of postoperative period.
