ABSTRACT Peripheral nerve blocks have aroused increasing interest in recent years, leading to a rise in the rate of complications. At the same time noteworthy technical advances have been made in areas such as nerve stimulation and ultrasound imaging, and local anesthetics have become safer. Nevertheless, the risk of anesthetic-related systemic toxicity, which manifests with neurological symptoms that tend to be forerunners of cardiovascular ones, can not be ignored. We report 2 cases of systemic toxicity due to the use of a mixture of local anesthetics during nerve blocks for outpatient surgery.
