Abstract :

Objective: To evaluate the interest of parietal infiltration with bupivacaïne of the surgical wound under spinal anesthesia on the prevention of post caesarean section pain.

Material and methods: This is a prospective, comparative and analytical study over a period of 5 months from November 2014 to March 2015 in the department of anesthesiology–resuscitation and maternity of teaching hospital Tambohobe Fianarantsoa. Randomly, a group of parturients operated on spinal anesthesia received postoperatively a single parietal infiltration of 20 mL of bupivacaine (WIG) and another group non–infiltrated (NIG). The average visual analogue scale (VAS), the consumption of analgesics, the delay of recovery of the intestinal transit and the cost of hospitalization were studied.

Results: Eighty parturients were included in the study. They were divided into 2 groups, 40 in the group without infiltration (NIG) and 40 in the group with infiltration of 20 mL of bupivacaine 0.5% at the end of intervention (WIG). The mean VAS and the postoperative analgesic consumption were significantly reduced in the WIG compared to the NIG, with p values of 0.001 and 0.042, respectively. The return of transit was observed in less than 24 hours in 47.5% of the WIG against 25% of the NIG (p = 0.007) and the cost of hospitalization was increased by Ar 50 000, or $ 23 for the NIG.

Conclusion: These results showed the interest of parietal infiltration with bupivacaine in the management of pain after caesarean section with a reduction in analgesic consumption and the cost of hospitalization.
