Abstract
Background: Caudal block is the most commonly used technique of regional anesthesia performed 
on children that is suitable for use during various types of surgical interventions located below the 
level of the navel .This technique provides a safe approach to the epidural space in children. Patients 
and Methods: A total of 40 pediatric patients of both sex, ASA I and II, aged between 2 to 6 years, 
scheduled for lower abdominal surgery, under general anesthesia were included in the study. Patients 
were randomly allocated into 2 equal groups each containing 20 patient. Group (CB) received 
ultrasound guided Caudal Block in a dose 2.5mg/kg of bupivacaine (0.25%) and group (C) didn't 
receive any block. Results: There was a significant increase in HR, Systolic and Diastolic blood 
pressure in the Control group than (CB) group that had more hemodynamic stability Conclusion: we 
concluded that caudal block is an easy and safe technique and causes more hemodynamic stability.
