Abstract

Background: The efficacy of two different volumes of 0.25% bupivacaine for caudal blockade, in children undergoing inguinal hernia repair surgery regarding hernia pouch traction, was evaluated. Patients & Methods: Forty children aged between 1 to 5 years, undergoing elective inguinal herniorrhaphy or hydrocele repair were enrolled in the study. Patients received a caudal blockade either with bupivacaine 0.25% at 1.0 ml kg-1 (n=20), or bupivacaine 0.25% at 1.1 ml kg-1 (n=20). After caudal blockade inhalation Anaesthesia was stopped and Anaesthesia was maintained with a propofol infusion. Results: There were no significant differences between the groups with respect to sex distribution, age, weight, type of surgery, duration of Anaesthesia and surgery, and recovery time. None of patients developed a hemodynamic or respiratory problem. No nausea or vomiting was observed and no urinary retention was noted. The Anaesthesia onset time was shorter, the reached peak sensory level was higher, and duration of analgesia was longer in children receiving 1.1 ml kg-1. Total propofol consumption was statistically higher in children receiving 1.0 ml kg-1. Caudal Anaesthesia has been adequate to block the hernia pouch traction response during surgery in children receiving 1.1 ml kg-1. There were no significant differences between groups in the incidence of residual motor blockade. Conclusions: This study indicates that in children undergoing inguinal hernia repair surgery bupivacaine 0.25% at 1.1 ml kg-1 is more reliable.
