Comparing the analgesic efficacy of transversus abdominis plane block versus wound infiltration for post cesarean section pain management: A prospective cohort study

Cesarean section is the most common surgery done in the world and it results moderate to severe pain. Untreated pain interrupts the mother to care her baby and may lead to the development of chronic pain. It may also have negative impacts on respiratory, cardiovascular and other systems. Land mark technique of transversus abdominis plane block and wound infiltration have been practiced to manage post-operative pain after cesarean section. Comparing the analgesic efficacy of transversus abdominis plane block versus wound infiltration for post cesarean section pain management. An institution based prospective cohort study was conducted on 82 parturients who delivered by cesarean section under spinal, North west Ethiopia, from March10 to June 2nd, 2020. Data was collected using a structured questionnaire and 82 consecutive parturients were included in this study until the desired sample in each groups was achieved. Parametric data was compared by independent student t –test and non-parametric data was compared by Mann-Whitney U test and presented as mean ± standard deviation or median (interquartile range) as appropriate. Post-operative numerical rating scale of pain after cesarean section at 2, 4 and 6 h were not significantly different, but there were significant differences at 8, 12 and 24 h between groups. Diclofenac consumption was not significantly different on 24 post-operative hour between the two groups (P = 0.246). Time to first analgesia requirement was prolonged in transversus abdominis plane block (p
