Rectal Versus Intramuscular Diclofenac for Pain Relief Following Caesarean Section

Overview

Caesarean section (CS) is one of the commonest major Obstetric surgeries worldwide and its rate has markedly increased globally. Pain control is an integral part of enhancement of recovery after caesarean section and NSAIDs have been used in combination with opioids for post-operative pain management in recent times. There are sparse data on maternal satisfaction with suppository diclofenac or any data from our centre that compared the intramuscular and rectal routes of diclofenac administration. Hence this study was conceived to compare the efficacy of rectal diclofenac and intramuscular diclofenac as an adjunct to intramuscular pentazocine in the management of post-operative pain in women who have elective caesarean section.

Background: Caesarean section (CS) is one of the commonest major Obstetric surgeries worldwide and its rate has markedly increased globally. Pain control is an integral part of enhancement of recovery after caesarean section and NSAIDs have been used in combination with opioids for post-operative pain management in recent times. There are sparse data on maternal satisfaction with suppository diclofenac or any data from our centre that compared the intramuscular and rectal routes of diclofenac administration. Hence this study was conceived to compare the efficacy of rectal diclofenac and intramuscular diclofenac as an adjunct to intramuscular pentazocine in the management of post-operative pain in women who have elective caesarean section. Aim: This study is designed to compare the efficacy of rectal diclofenac with that of intramuscular diclofenac as pain relief among women after elective Caesarean section at Alex-Ekwueme Federal University Teaching Hospital, Abakaliki. Methods: This was a randomized equivalence controlled trial conducted among pregnant women booked for elective Caesarean section at Alex-Ekwueme Federal University Teaching Hospital Abakaliki, comparing the efficacy of rectal diclofenac with that of intramuscular diclofenac as pain relief among women after elective caesarean section at term. One arm received 100mg of suppository diclofenac and the other arm received 75mg of intramuscular diclofenac. These doses were repeated every 12hours for 24 hours. Pain scoring was done at 1, 6, 12, 18 and 24 hours after administration of the drugs. The data obtained was analysed using IBM SPSS software (version 23, Chicago II, USA) and the intention to treat concept. A difference with a P value of ≤ 0.05 was taken to be statistically significant.
