The study conforms to the provisions of the Declaration of Helsinki in 1995 (as revised in 
Edinburgh 2000) and it was ethically approved by the Research Committee for Government 
Hospitals, Salmaniya Medical Complex, Kingdom of Bahrain (IRB number: 70130623). 
Selecting the best analgesia method in pediatrics is so important. This is a randomized 
a prospective study conducted on 90 children who underwent circumcision. The results showed 
that circumcision in pediatrics using a caudal block can provide longer analgesia for the patient. 
ABSTRACT 
Background: 
Caudal block (CB), dorsal nerve penile block (DPNB), and systemic opioids are common 
techniques used in pediatric surgeries to provide analgesia for penile surgery such as 
circumcision. 
Aims: This study aimed to compare the effectiveness of the CB with other methods of 
postoperative pain release. 
Material and Methods: The main operation pediatric theater and post-anesthesia recovery unit 
(PACU) in the Government Hospitals, Salmaniya Medical Complex, Bahrain. 
Study subjects: Successive children aged 3 months to 3 years who had American Society of 
Anesthesiologists with Physical Status classification one and who had undergone elective 
circumcision 

surgery were recruited., Children were randomized to one of three modalities of intraoperative 
analgesia: CB, or DPNB. And systemic opioids. 
study design: Prospective, Observation-randomized, case-controlled trial study. a study Sample 
size: all patients, for a total of 90 boys going for circumcision surgery. I was recruited over the 
course of four months, starting in May 2023. The patients will be divided into three groups: A 
(CB), B systemic opioids, and C (DPsNB). All patients had operations and were observed, and the 
three groups were compared based on hemodynamic stability, pain scores, duration of 
sedation, 
analgesia need, and parental satisfaction. where the Face, Leg, Activity, and Cry Consolability 
s(FLACC) pain scale and behaviors were used to observe and compare the three Groups.
