Enoximone and warming after hypothermic cardiopulmonary bypass.
In a randomized, controlled study of 24 patients undergoing myocardial revascularization, we found that enoximone 0.5 mg kg-1 i.v., followed by 5 micrograms kg-1 min-1, when rewarming after hypothermic cardiopulmonary bypass, prevented subsequent cooling of the periphery after transfer to the intensive care unit. Skin surface temperatures on the foot increased by mean 0.33 (SD 0.5) degree C h-1...
متن کاملHypothermic Cardiopulmonary Bypass
Background and Purpose We evaluated the utility of blood flow velocity measurements by transcranial Doppler ultrasonography as a tool to indirectly measure cerebral perfusion during cardiopulmonary bypass. Methods We simultaneously measured blood flow velocity in the middle cerebral artery and physiological variables in 18 patients undergoing cardiac surgery under hypothermic cardiopulmonary by...
متن کاملEffect of modified ultrafiltration on pulmonary function after cardiopulmonary bypass.
BACKGROUND Pulmonary dysfunction is one of the most common manifestations of inflammatory response after cardiopulmonary bypass (CPB). OBJECTIVE This prospective randomized study was conducted to evaluate the effect of a modified ultrafiltration (MUF) technique on pulmonary function after CPB in children. METHODS Forty patients weighing from 5 to 10 kg with congenital heart disease who requ...
متن کاملMyocardial Preservation during Hypothermic Cardiopulmonary Bypass: A Team Endeavor
____________ _ Myocardial failure is the primary cause of death following operation using hypothermic cardiopulmonary bypass. The mean mortality rate for coronary bypass in Medicare patients in the United States for 1984 was 5.5%.1njury to the heart is caused by aortic cross-clamping or total circulatory arrest. The lesion of hypoxia is characterized by progressive acidosis. The severity of aci...
متن کاملEffect of exercise training and L-arginine supplementation on oxidative stress and left ventricular function in rats with myocardial infarction
Introduction: The aim of the present study was to evaluate the effect of exercise training and L-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (MI). Methods: Four weeks after the surgically-induced MI, 40 male Wistar rats were randomly assigned to the following 4 groups (n=10): MI-sedentary control (Sed) MI-exercise (Ex) MI-...
