Official Title: Effectiveness of Caudal Epidural Block on Intraoperative Blood Loss During Hypospadias Repair; A Randomized Clinical Trial
Brief Summary:
From September 2014 to March 2015, 57 consecutive patients with hypospadias who are candidate for surgery will be enrolled in this randomized clinical trial.
Regional ethics committee of Isfahan University of Medical Sciences approved the protocol of the study and all parents will sign a written informed consent.
Inclusion criteria are age between 6 months to 15 years and hypospadias with any severity. Exclusion criteria are coagulopathy, history of previous failed surgery, skin infection , parents' disagreement with the protocol and any cardiac problem that made epinephrine injection contraindicated.
All selected patients will randomly allocate to one of the two groups: group A will receive caudal epidural block (CEB) plus general anesthesia before surgery and group B will receive general anesthesia before surgery and CEB afterwards. The surgical procedures will be performed by a single pediatric urologist (FA). The surgical technique will be tubularized incised plate in all cases.
Intraoperative blood loss will be determined by weighing all surgical gauzes used during procedure with a digital scale measure to the nearest 0.01 gram, every 10 minutes to minimize the effect of water vaporization on gauzes weights.
In addition to blood loss, operation time, dose of fentanyl used during procedure and length of the urethral plate defect will be recorded for each patient by trained nurses.
Demographics and disease characteristics as well as operation details will be compared in the two studied groups.
