Intraoperative Surgeon Administered Adductor Canal Blockade Is Not Inferior to Anesthesiologist Administered Adductor Canal Blockade: A Prospective Randomized Trial

摘要

Background: Controlling postoperative pain and reducing opioid requirements after total knee arthroplasty remain a challenge, particularly in an era stressing rapid recovery protocols and early discharge. A single-shot adductor canal blockade (ACB) has been shown to be effective in decreasing postoperative pain. The purpose of the present study is to compare the efficacy of an anesthesiologist administered ACB and a surgeon administered intraoperative ACB.
