Caudal block involves the introduction of local anesthetic into thecaudal epidural space.Ilioinguinal/iliohypogastric nerve blocks is also the most common abdominal wall blocks provide effective analgesia for surgical procedures of inguinal area. Objectives To compare the analgesic efficacy of caudal and ilioinguinal/iliohypogastric nerve blockade using bupivacaine for children under going inguinal surgeries at Menelik II hospital. Methodology An institutional based prospective cohort study was conducted on 70 patients who under gone inguinal surgeries under general anesthesia. Patients in CB group (n=35) received caudal block and IL/IH group (n=35) received ilioinguinal/iliohypogastric nerve block after induction of anesthesiabased on the independent decision of anesthetist.Study participants were selected by Systematic random sampling technique. P-value less than 0.05 was considered as statistically significant. Result : - This study found that caudal block has prolonged postoperative analgesia with a mean duration of 301.5±73.5 minute compared to 242.4±66.4 minutes in Ilioinguinal/iliohypogastric group (p=0.001). Total analgesic consumption and pain severity was comparable between the groups (p>0.05) which is not statistically significant. Conclusion and Recommendation : we found that caudal epidural had prolonged duration of analgesia as compared to Ilioinguinal/iliohypogastric nerve block. Based on our finding we recommend the use of caudal block as effective post-operative analgesia for inguinal surgeries in pediatrics.en-USAnalgesic efficacy , caudal , ilioinguinal ,iliohypogastric nerve blockade,bupivacaine, inguinal surgeriesThesis
