Oxygen consumption (VO2), carbon dioxide production, respiratory quotient, urinary nitrogen excretion (UN), resting energy expenditure (REE), REE rate (%REE) and consumption rates of carbohydrate (%C), fat (%F) and protein (%P) were pre and postoperatively measured in the acute stage of 17 patients with cerebrovascular diseases. They included six of ruptured intracranial aneurysms, six of cerebrovascular occlusion, and five of hypertensive intracerebral hemorrhage. Preoperative VO2, UN, REE, and %REE were 185.1 ml/min, 7.1 gm/day, 1280 cal/day, and 132.6, respectively. %C, %F, and %P were 40.9, 38.5, and 20.6, respectively. Especially the preoperative %P had markedly increased. Postoperatively, %C significantly decreased to 28.3, and %P showed a significant increase up to 30.3. Patients with ruptured intracranial aneurysms manifested a significant increase of %P and %F and a decrease of %C, postoperatively. In summary, the catabolism of fat and protein increases in the acute stage, especially postoperatively, and this hypermetabolic state should be considered when caring for patients with cerebrovascular diseases as malnutrition might prevent wound healing and cause weight loss and a decrease in immunity.
