Objectives: In this study, we evaluated the analgesic efficacy and adverse effect profile of levobupivacaine in caudal and DPNB
in postcircumcision pediatric patients.
Methods: Sixty boys between 2-10 years of age undergoing circumcision were enrolled. The patients were divided into two
groups: Group C (n=30) and Group P (n=30) were applied caudal block or dorsal penile nerve block (DPNB), respectively.
Blocks were performed before surgery as a supplement to general anesthesia with 1 mL kg-1 0.25% levobupivacaine. Postoperative
pain and sedation scores were assessed on the 10th and 30th minutes, and hours 1-6. The number of pain free
patients in the first 6 hours, the duration of analgesia, time to first analgesic administration, walking, micturition, and total
paracetamol demands, and length of stay were recorded.
Results: Demographic data were similar between groups. The number of children who spent the first 6 hours pain-free was
larger in Group C than Group P (p=0.0001). The time to first analgesic (p=0.000033) and walking (p=0.004) were longer
in Group C. There were 14 patients with motor block in Group C (p=0.00007). In view of AUC, FPRS, OPS and MPOPS
were significantly better in Group C on the first postoperative 6 hours.
Conclusion: Caudal block done using levobupivacaine for postoperative pain management in circumcision is more successful
than penile block, however there is a significant delay in time to first walking and as might be expected there is an increased
risk of motor block
