The effect of regional anesthesia of the nerves of the pelvic limb on hemodynamic parameters during operations on the anterior cruciate ligament in dogs

The article presents data on the study of the effect of regional anesthesia of the nerves of the pelvic limb during operations on the anterior cruciate ligament in dogs on hemodynamic parameters: heart rate and average blood pressure. The study was performed throughout the entire surgical intervention. Indicators of the state of circulatory function were recorded before anesthesia, after induction and after 5, 10, 20, 30, 40, 50, 60 minutes after the injection of a local anesthetic, then 10 and 20 minutes after waking up. Depending on the method of anesthesia used, the experimental animals were divided into 4 groups. In the course of the study, it was found that the heart rate in dogs significantly increased, and the average blood pressure decreased when performing surgery on the anterior cruciate ligament under epidural anesthesia and multimodal analgesia in comparison with the group where dogs underwent anesthesia of the lateral cutaneous nerve of the thigh. Such dynamics of indicators can lead to inhibition of circulatory function, which increases the risk and probability of resuscitation during reconstructive knee joint operations.
