Preventive effect of ilioinguinal nerve block on postoperative pain after cesarean section

Background: Cesarean section is a major operation that can be the predictor of postoperative pain and discomfort and, therefore, providing the effective postoperative analgesia is an important factor to facilitate sooner movement of the patient, better care of infants. The aim of this study was to determine the preventive effect of ilioinguinal nerve block on pain after cesarean section.
Materials and Methods: In a randomized clinical trial study, 80 female candidates for cesarean section under general anesthesia were selected and divided into two groups. In the first group, ilioinguinal nerve was blocked and in the control group, ilioinguinal nerve block was not done. Finally, postoperative pain was compared between the two groups.
Results: The mean pain intensity at 6 and 24 h after operation had no significant difference between two groups but in the rest of the times, it was different between two groups. Furthermore, in sitting position, except for 6 h, the pain intensity at the rest of the time had a significant difference between two groups. The pain intensity in 12 h after operation had a significant difference while in 24 h after operation; there was no difference between two groups. Doing repeated measures, ANOVA also indicated that the process of changes in the pain intensity in three positions of rest, sitting and walking had no significant difference up to 24 h after operation (P < 0.001).
Conclusion: Control of pain after cesarean as one of the most common factors for abdominal surgery will lead to decrease the staying of the patient in hospital, reduce morbidity and lower use of narcotics and analgesics after surgery.
