A Prospective Randomized Comparative Study of Hyperbaric Ropivacaine vs. Hyperbaric Bupivacaine in Spinal Anesthesia for Elective Infraumbilical Surgeries

< 0.05 was considered statistically significant. The mean time to sensory and motor onset was longer in Group R (5.93 ± 1.86 min and 10.53 ± 2.03 min) when compared with Group B (3.20 ± 1.24 min and 7.93 ± 2.13 min) while the mean sensory and motor duration was shorter in Group R (146.57 ± 15.60 min and 108.87 ± 25.33 min) as compared with Group B (179.30 ± 21.35 min and 135 ± 14.10 min), both of which were statistically significant. Hyperbaric ropivacaine 0.75% has a slower onset and longer time to maximum spread but faster recovery, making it a safe alternative to bupivacaine.
