A study to compare 0.5% hyperbaric bupivacaine with 0.5% isobaric ropivacaine intrathecally for elective lower limb surgery.
Background: Spinal anaesthesia is the most appropriate method that is more advantageous than general anaesthesia. The study was planned to comparatively assess the effects of hyperbaric 0.5% Bupivacaine with isobaric 0.5% Ropivacaine in Elective Lower Limb Surgery.
Methodology: One hundred patients belonging to American Society of Anesthesiologists (ASA) class I and II were selected for elective lower segment operation. Participants were assorted into two groups without following any fixed criteria and treated as; Group B and R, injected with bupivacaine in 0.5% hyperbaric condition and 0.5% isobaric ropivacaine, respectively.
Results: The time of onset of blockage of sensation was prominently lesser in Group B contrary to Group R. The time slot of attainment of maximum sensory block up to T6 level was statistically significant and was smaller in Group B. The duration for the two-segment regression's sensorial blockage was more duration in Group B. The average extent of blockage of sensation was lesser in the R group. The time to achieve maximum motor blockage when testing via Bromage scale 2 was lower in the B group. In group B, the mean duration of the motor blockade was calibrated from the Bromage scale.
Conclusion: The use of ropivacaine given for lower segment surgeries provided an efficient level of block required during the surgery with a speedy outset of motor and sensory blockade and less time needed to achieve motor blockade.
