The effect of preemptive intravenous ketamine on postoperative pain in patients undergoing arthroscopic rotator cuff repair with intra articular ropivacaine injection

摘要

Background: A low dose of ketamine can be an effective preemptive analgesic by preventing central sensitization when administered before surgical trauma. In this study, we assessed the preemptive analgesic effect of low-dose ketamine administered intravenously to patients undergoing arthroscopic rotator cuff repair with intra articular ropivacaine injection.
