Epidural Naloxone Attenuates Fentanyl Induced PONV in Patients Undergoing Lower Limb Orthopaedic Surgeries. a Prospective Randomized Double-Blind Comparative Study

摘要

Epidural administration of opioids with local anaesthetics is a popular choice for perioperative pain relief. But opioid induced side effects limit their use for postoperative analgesia. Hence, this study was designed to evaluate the effectiveness of epidural naloxone, an opioid receptor antagonist, in reducing PONV in patients receiving epidural fentanyl.
