Background Caudal block is a common regional technique performed for infra umbilical surgery in pediatrics. Its limited duration of analgesia remains a gap in routine clinical practice. This study aimed to assess the analgesic effectiveness of caudal block with rectal diclofenac or rectal paracetamol among pediatric patients who underwent infra umbilical surgery. Methods A prospective cohort study was conducted on patients aged 1–10 years that underwent elective infra umbilical surgery. Patients were allocated into the Caudal block with rectal Diclofenac, Caudal block with rectal Paracetamol, and Caudal block alone groups based on a postoperative pain management plan. Analysis of variance was used for normally distributed data and the Kruskal Wallis H test was used for non-normally distributed. The Tukey for post hoc test was used to compare the difference between groups one with the others. Categorical data were analyzed by using Pearson Chi-squared or Fisher's exact test as appropriate. A p-value < 0.05 considered as statistically significant. Results The postoperative median pain score was lower in CD compared to CP and CA group (p-value < 0.001) at the 4th and 8th hour. Time to first analgesic request was significantly longer within CD 735 (540–1200 min) compared to CP 445 (240–840 min p = 0.029) and CA 315 (240–720 min p < 0.001). Conclusion The pain score and total postoperative analgesic consumption were significantly reduced in addition to prolonged-time to request the first analgesia in the CD group compared to CA and CP group.
