Abstract
Background and Aims: Postoperative pain remains the most important cause of morbidity. Thus, a good postoperative analgesia is required but at the same time any untoward complication is to be avoided as patient is in a ward setting which is not a continuous monitoring setting always. Epidural local anaesthetics with good safety profile remain a safe modality in such settings. Our aim is to compare the efficacy, haemodynamics and side effects of Epidural 0.2%Ropivacaine versus 0.2%Bupivacaine for post-operative analgesia in abdominal surgeries.Materials and Methods: A comparative study of 80 patients undergoing elective abdominal surgeries were allocated into two groups using Computer generated randomization. Postoperatively, one group received epidural Bupivacaine 0.2%, upto10cc and other received ropivacaine 0.2% 10cc. Pre-emptive epidural analgesia in the form of Bupivacaine/Ropivacaine administered at the time of closure and duration of analgesia was taken from time of extubation till analgesic is asked for the first-time post operatively. Rescue analgesia administered in the form of epidural Bupivacaine or Ropivacaine in the respective groups. Assessment done by a blinded anesthesiologist. Statistical analysis done using SPSS software version 20 and Epi Info 7.2.1.
Result: Though both the drugs maintained a comparable hemodynamic profile, there was better patient comfort at rest in ropivacaine group with lower VAS scores and lesser demand for rescue analgesia. Significantly higher number of adverse effects were found in bupivacaine group (n=36) as compared to ropivacaine group (n=6), specifically, fall in blood pressure and motor deficit.
Conclusion- Ropivacaine provided better post-operative analgesia as patients required lesser amount of rescue analgesia as well as mean time was comparatively longer for the first top up in comparison to Bupivacaine. Ropivacaine was also found to have a better safety profile alongwith distinct motor sensory differentiation
