Comparison of 0.75% Hyperbaric Ropivacaine Alone versus 0.75% Hyperbaric Ropivacaine with Fentanyl in Spinal Anaesthesia for Infraumbilical Surgeries: A Double-blinded Randomised Controlled Study

Introduction: Spinal anaesthesia is preferred for infraumbilical surgeries due to its rapid onset and effective postoperative analgesia. Ropivacaine, a long-acting local anaesthetic with reduced cardiotoxicity, is increasingly used with adjuvants to enhance block characteristics. Intrathecal adjuvants like fentanyl are being increasingly used to improve or prolong the anaesthetic and analgesic effects. Aim: To compare the effects of 0.75% hyperbaric ropivacaine alone versus 0.75% hyperbaric ropi
