Abstract
There have been only few studies on the calorie requirement immediately before and after the operation. In order to ascertain whether the calorie requirement is satisfied or not in the present condition of rationing in the hospital, the authors investigated on the calorie requirement of the patients with tuberculosis who has undergone pulmonary resection and obtained the following results:
1) In spite of the condition near absolute rest during the period of several days after the operation, the calorie requirement of the patients were found to be from 2, 900 to 2, 500 cal., suggesting the necessity of high-protein and high-calorie diet.
2) The calorie requirement after the operation, although varying somewhat according to the period after the operation, showed a value of 10 per cent of what it was before the operation.
3) Although the negative nitrogen balance immediately after the operation was marked, the balance recovered to the level before the operation in the third week and remained this level thereafter.
4) During the first week after the operation, neither calorie nor protein requirement was found to be satisfied.
5) In the present condition of the rationing in our sanatorium, the amount of both calorie and protein is not sufficient.
