Comparing caudal block and penile block using rectal acetaminophen in postoperative analgesia of hypospadias repair: A randomized clinical trial study

Abstract

Background and objectiveselecting the analgesia method in pediatrics is of most importance.In pediatrics required hypospadias repair, two methods of the caudal block and penile block are used increasingly. This study aimed to compare two methods of the caudal block and penile block using rectal acetaminophen in postoperative analgesia of hypospadias repair. MethodsThis clinical trial was conducted on 50 children who underwent hypospadias referred to the educational hospital of Shahid Motahari in Urmia in west-north of Iran from July 1st, 2019 to March 1st, 2020. Patients were selected using a convenient sampling method and were allocated in two groups of the caudal block and penile block using rectal acetaminophen by random allocation software. To assess analgesia, the FLACC scale was used. ResultsMean age of participants was 27 months, the mean weight of participants was 13 kg, and their mean height was 82 cm. Regarding assessment changes in pain severity, the results showed in two groups that in group 1 (caudal block) in time intervals of recovery, 6 h, 12 h, and 24 h after the surgery, pain severity was reached to 1.16 and in group 2 (penile block) was reached to 3.44. The results showed that in group 1 (caudal block) patients suffer significantly less pain than patients in group 2 (penile block) (P = 0.001). ConclusionsAccording to results obtained from this study, hypospadias repair in pediatrics using caudal block can provide longer analgesia for the patient.
