Evaluation of Post-Cesarean Pain after Intraperitoneal Lidocaine Instillation Versus Intravenous Lidocaine

Background: Post-caesarean pain control is an essential issue with multiple methods were used to manage it. We aimed to compare the effect of intraperitoneal lidocaine installation and intravenous lidocaine injection on postoperative pain and analgesic requirements in patients undergoing a cesarean section.Methods: A150 pregnant, full term female patients scheduled for cesarean section were enrolled in a prospective randomized controlled study. Random allocation of patients was performed, with 50 patients in each group. Group C (control group): Normal saline was given both intraperitoneal and intravenously during caesarean section, Group P (intraperitoneal group): Received intraperitoneal instillation of lidocaine and saline intravenous injection, Group I (intravenous group): Was given an intravenous lidocaine injection and an intraperitoneal instillation of saline. We measured postoperative pain scoring and the need for postoperative analgesia.Results: Lidocaine administration either intravenously or intraperitoneal compared to the control group during caesarean section under general anesthesia provided a significant degree of analgesia as shown by lower visual analogue scale scores and reduced opioid consumption and early ambulation.Conclusion: No difference between intravenous lidocaine and intraperitoneal lidocaine when used as an analgesic for cesarean section.
