An intact tourniquet is necessary to establish and maintain IVRA. If failure of the tourniquet occurs, the local anesthetic will leak into the systemic circulation. If the amount of local anesthetic leaked is high enough, it can cause systemic signs of toxicity such as seizures, which is the most common complication of faulty tourniquet reported in the human literature [105].

There are no reports of systemic toxicity due to leakage of local anesthetic during IVRA in horses. The occurrence of systemic toxicity manifesting as seizures due to local anesthetic leakage during IVRA in humans is very rare, with an incidence of 2.7 per 10,000 cases [105].
