Summary
Brief summary
During nerve blocks (which can control postoperative pain effectively), various drugs have been proposed in combination with local anesthetics (LA) to help reduce onset time and to prolong the duration of action and postoperative analgesia. Clonidine, epinephrine, and opioids are such examples but they are not without side effects.

Tramadol and dexamethasone was proposed as safe adjuvents to LA but there were no study comparing those two molecules in ultrasound guided (US) peripheral nerve blocks.
