A meta-analysis of adult human randomized controlled studies that compared single dose perioperative intrathecal ketamine plus intrathecal bupivacaine to bupivacaine alone in spinal anesthesia suggests that there is a benefit to using intrathecal ketamine as an adjunct to bupivacaine in multimodal analgesia. However, there are still knowledge and experience gaps regarding neuraxial ketamine dosing in this regard.~Aim of the study:~The aim of this study is to compare the postoperative analgesic effect of three different doses of intrathecal ketamine as an adjuvant to bupivacaine in patients undergoing knee arthroscopy.
