Background: Caesarean section is the most widely performed obstetric procedure. Caesarean section commonly induces moderate to severe pain lasting 48 hours after surgery. There are various modalities available for postoperative pain relief ranging from parenteral analgesia (NSAIDS and opioids), epidural analgesia etc. So, we have to compare whether 30 ml of 0.25% intraperitoneal instillation and incisional infiltration bupivacaine and ropivacaine can produce effective pain relief caesarian section.

Material & methods:Acomparative study to be conducted on 50 patients undergoing elective as well as emergency caesareans section under spinal anaesthesia.After obtaining history, clinical examination and investigations, patients will be randomly allocated in two groups of 25 each as follows:  Group R : Intraperitoneal instillation and incisional infiltration of 30 ml of 0.25% plain ropivacaine& Group B : Intraperitoneal instillation and incisonal infiltration of 30 ml of 0.25% plain bupivacaine.

Results: Our study showed that no difference was found in age (35.3±10.8 yr vs. 33.2±12.3yr), duration of surgery (1.38±0.52 hrs vs. 1.29±0.54 hrs) between Group R and Group B (p>0.05). Statistically significant difference (p<0.05) was found in pain intensity of the visceral and parietal pain within the groups during first 4–6 hrs in the postoperative period.

Conclusion:From present study it is concluded that Postoperative infiltration of the surgical incision in Caesarean section with 0.25%ropivacaine30ml gives effective analgesia for several hours and decreases systemic analgesic consumption as compared to same dose of bupivacaine. This technique could be considered as an integral part of the analgesic protocol in patients scheduled for Caesarean section.
