Abstract

Local anesthetics for lower limb anesthesia frequently use ropivacaine and bupivacaine due to their unique pharmacological properties. The point of this study was to look at how well efficacy of hyperbaric 0.5% bupivacaine with fentanyl and hyperbaric 0.75% ropivacaine with fentanyl worked in spinal anesthesia and compare and talk about them. Each group evaluated a total of 30 patients using various parameters to assess side effects and complications. We found among patients receiving bupivacaine, 70.0% did not require rescue medication, whereas 30.0% did. In contrast, among patients receiving ropivacaine, 86.7% did not require rescue medication, while 13.3% did. Thus, found non-significant difference. Bupivacaine has a faster onset and longer duration of sensory block and motor block, providing better early pain alleviation than ropivacaine.
