The extracorporeal membrane oxygenation (ECMCMO) is a technique of prolonged cardiopulmonary support, which aims to help the lungs or the heart when these organs present failure processes not responsive to conventional treatments. As it is not a physiological procedure, it represents a major challenge for medicine, which seeks to make it a safer procedure. Thus, this research was carried out to determine the course of the cardiac markers CK and CK-MB of five dogs submitted at ECMO for three hours. Mongrel dogs of various ages, weight and sex were used. Under anesthesic maintenance, the animals were subjected to femoral cannulation for ECMCMO, in an arterial-venous (AV) deviation. Once the circuit was established, the variables were measured every thirty minutes for a period of three hours. The data were statistically analyzed with Anova, Tukey and Pearson Correlation, with α = 5%. The results showed an increase of serum CK and CK-MB, characterizing a muscular injury during the procedure. The results showed that ECMO induced a cardiac muscle injury by a physiological mechanism. It was concluded that ECMCMO is a viable technical support and do not induce myocardial injury in dogs during a period of three hours.
