Is 075% Ropivacaine More Efficient than 05% Bupivacaine for Prolonged Sensory Blockade in Epidural Anaesthesia for Orthopaedic Hip Surgeries?

ABSTRACT

The efficiency of 0.75% Ropivacaine as a single shot epidural anaesthetic in comparison to 0.5% Bupivacaine is less studied. Our study focuses on comparing the efficiency of sensory block between 0.75% ropivacaine and 0.5% bupivacaine for epidural anaesthesia. Methods: The study was done with 0.75% Ropivacaine and 0.5% Bupivacaine in epidural anaesthesia in orthopedic hip surgeries given as a single shot technique for which 60 patients of ASA I/II each were chosen and 15ml of the drug was given. Onset of the sensory sensations at T12 and regression at the same level were measured with the aid of response to pin prick and thus duration of epidural anaesthesia was calculated individually in group B and group R respectively. Results: Onset of sensory block was faster in group R than in group B and regression was slower in group R than in group B. Conclusion: It can be concluded that duration of epidural anaesthesia was prolonged and longer with 0.75% Ropivacaine than 0.5% Bupivacaine.
