[The significance of body weight measurement of esophageal cancer patients in intra- and postoperative fluid administration].
We tried to clarify the intra- and postoperative pathological state in resected thoracic esophageal cancer patients and analyze the particularity of fluid administration by measuring body weight at certain time serially. We studied 26 resected thoracic esophageal cancer patients between September, 1989 and January, 1991 who underwent an operation through right thoracotomy prior to laparotomy at the same time, and all cases were under general anesthesia combined with epidural anesthesia. We measured body weight preoperatively, just after operation, on the first, second and third postoperative days by means of LIFTER (Ted Hoyer & Co. Inc), and also calculated water balance and measured pressures and cardiac output by Swan-Ganz catheter in 19 cases. As a result, change in body weight was remarkable in resected thoracic esophageal cancer patients intra- and postoperatively. The peak of weight gain was noticed and they gained about 3 kilograms in weight on the 1st postoperative day, while in circulation hypovolemia was found on the data by means of Swan-Ganz catheter. There was a high correlation between rate of change in weight (kg/hr) and water balance (ml/kg/hr) (r = 0.91). We calculated insensible loss by the difference between water balance and body weight. It was about 1.73 intraoperatively, 0 postoperatively, 0.35-0.5 ml/kg/hr on from the 1st through the 3rd postoperative day. It is concluded that body weight measurement is a very easy, precise and useful bedside technique in the intra- and postoperative fluid administration of esophageal cancer patients, because it is very important not only to understand the circulation volume but also to know the interstitial fluid change.
