Resumo: |
The ambulatory electrocardiography (ECG-Holter) is a method to obtain the electrocardiographic tracing continuously, noninvasively for prolonged periods (24 hours). Changes in cardiac conduction and arrhythmias can be observed frequently during the perioperative period (pre, during, and post), however this tends to be more careful monitoring before and during surgery. It was shown that there is always the risk of arrhythmias in the postoperative period, but there are few studies in dogs detecting and comparing the electrocardiographic changes during the perioperative period. In this work, we intend to perform a more comprehensive evaluation by electrocardiographic monitoring during the periods before, during and post-anesthesia using the electrocardiogram continuous 24 hours (ECG-Holter) in dogs. It were used 23 dogs underwent to elective surgical procedures and allocated into three groups, young dogs or young adults (GAS), dogs with cardiac disease (GCP) and older dogs (GAI). There were no clinically significant changes in the variables evaluated during the trans-anesthetic. There were no statistical differences between the quantities of arrhythmias observed in the three groups and at different times. However, a greatest number of EV EVS were observed in GAI, especially in the post-anesthetic evaluation. A dog of GAI showed large amounts of ventricular arrhythmias caused by a hidden heart disease. There was no significant difference between the FC (max, min and mean) and HRV between the groups. The atrioventricular blocks (1 and 2) occurred in some dogs in three groups and were mainly observed at night in the pre-and post-anesthetic evaluations and few minutes after anesthetic induction. In conclusion, the anesthetic protocols used proved to be safe and cause few complications in dogs during the trans-anesthetic ECG-Holter monitoring proved to be practical, easy to use, and important for the perianesthetic evaluation in dogs. |
