Abstract
Aim and Objective: To evaluate the effect of penile block vs caudal epidural on the quality of analgesia and surgical outcome following hypospadias repair. Background: Intraoperative penile engorgement because of caudal epidural may result in tension on surgical sutures and alter surgical outcome. Methods: Fifty-four ASA I and II children were randomly allocated to group P (penile block, 0.25\% bupivacaine, 0.5 mg center dot kg-1; n = 27) and group C (caudal epidural, 0.25\% bupivacaine, 0.5 ml center dot kg-1; n = 27), respectively. Quality of analgesia was assessed by visual analog scale (VAS) score recorded at 0, 0.5, 3, 6, 12, 24 h, and once a day for the next 4 days. Duration of analgesia was calculated from the institution of block to the first analgesic demand by child or VAS > 5. Total morphine consumption in the first 48 h and oral paracetamol consumption till 5th day were recorded. Children were regularly followed up in their respective outpatient clinic for early or late complications. Results: In group P, lower mean VAS scores were seen from 0.5 h after surgery till day 3 and analgesia lasted for significantly longer duration (82 min) when compared with caudal epidural, P < 0.001. Incidence of urethral fistula formation after primary hypospadias repair was 19.2\%, and all had received caudal epidural. An increase of 27\% in penile volume from baseline value was observed 10 min after caudal epidural placement, P < 0.05. Conclusion: Penile block provided better analgesia when compared with caudal epidural in children undergoing primary hypospadias repair. Postoperative urethral fistula formation was more likely in children who received caudal epidural.
