Abstract

The technique of total circulatory arrest (TCA), or inflow occlusion, consists in preventing the blood entry into the heart chambers by clamping the vena cava and the cranial and caudal vena azygos. However, changes in physiological parameters of the patient can be triggered with the application of this technique. This technique can be easily used in heart intra-cavity diseases, whose correction takes a few minutes, as in pulmonary stenosis or subaortic stenosis. Because low cost and simple implementation, it may be carried out in private clinics. In this trial, the behavior of heart rate and body temperature of rabbits submitted to two periods of five minutes of TCA, by the use of inflow occlusion technique, was evaluated. A period of blood recirculation between occlusions was performed to verify the potential benefits of this practice on the behavior of heart rate and body temperature of the animals. These parameters were assessed throughout the perioperative period.There were two deaths, both in the recirculation period due to the occurrence of ventricular fibrillation. Nevertheless, with the implementation of the period of blood recirculation, we verified that this technique can be used in intra-cardiac surgery lasting up to 10 minutes
