O uso de adjuvantes na solução de anestésico local em bloqueios de nervos periféricos.

Abstract

For decades, regional anesthesia has been an extremely valuable tool for perioperative pain management. After advances in ultrasound technology, the use of peripheral nerve blocks has become even more common, as it provides greater patient and assistant team satisfaction, reduces opioid consumption, and contributes to early discharges. So, the idea of extending the duration of the sensory block becomes a very attractive concept. Therefore, there is a growing demand to find a solution that guarantees both a prolonged blockade and the least possible adverse effects. The association of adjuvants in the local anesthetic solution is both an easy and a low-complexity strategy. The present study discusses the efficiency and side effects of some of the pharmacological options most commonly studied as adjuvants.
