The Efficacy and Safety of Spinal Anesthesia With Hyperbaric Ropivacaine 0.75% and Bupivacaine 0.5% in Patients Undergoing Infra-Umbilical Surgeries: A Randomized, Double-Blind Study.

Curēus 2024 March
BACKGROUND: Spinal anesthesia utilizing hyperbaric 0.75% ropivacaine has been gaining clinical acceptance recently. It is a pure S-enantiomer of bupivacaine, which is expected to have a better clinical profile, but the studies for the same are yet limited. We aimed to compare the efficacy and safety of these two drugs.

METHODS: Sixty patients, aged 18 to 60 years of either sex, classified as American Society of Anesthesiologists class I and II, who were undergoing elective infra-umbilical surgery, were randomly assigned to receive either 3 mL of 0.5% bupivacaine heavy or 3 mL of 0.75% ropivacaine heavy intrathecally. Efficacy parameters, including the onset and duration of sensory and motor block, time to rescue analgesia, hemodynamics, and safety in terms of complications, were recorded. We compared the data for statistical significance, considering a p-value of less than 0.05 as significant.

RESULTS: Ropivacaine exhibited a slower onset for both sensory (153.90 ± 6.53 versus 92.46 ± 12.16 seconds; p < 0.001) and motor blockades (301 ± 6.62 versus 239.96 ± 6.27 seconds; p < 0.001). Two-segment sensory and motor blockade regression were faster with ropivacaine compared to bupivacaine (p < 0.001). However, the mean duration of sensory blockade for ropivacaine compared to that for bupivacaine (219.29 ± 15.14 versus 227.31 ± 17.20 minutes) and the requirement for rescue analgesia were not statistically different (p > 0.05). Ropivacaine also caused fewer side effects on a percentage scale.

CONCLUSION: In patients undergoing infra-umbilical surgery, hyperbaric ropivacaine at an equipotent dose (0.75%) proved to be a comparable and safer alternative to hyperbaric bupivacaine (0.5%). Furthermore, it had better motor-recovery profiles.
