Title: (227) Comparative Study of Intra-Articular Morphine, Fentanyl or Bupivacaine for Knee Surgery
Abstract: Introduction: After identification of peripheral receptors, a possibility was open to apply peripheral opioids in an attempt to use the strong analgesic effects of such drugs and, at the same time, avoid undesirable side effects. The aim of this study was to evaluate the analgesic effect of intra-articular morphine, fentanyl and bupivacaine in knee surgeries.
