Summary
Hypothesis: The combined use of Clonidine and Morphine in caudal anesthesia provides better
postoperative analgesia than either drug alone after urogenital pediatric surgery.
Clinical Details
Official title: Comparison of Clonidine and Morphine Plus Bupivacaine in Caudal Peridural Anesthesia for Postoperative Analgesia After Pediatric Urogenital Surgery
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment
Primary outcome: The overall postoperative consumption of analgesics.
Secondary outcome: The peroperative consumption of volatile anesthetics.The peroperative Bispectral Index measure. Postoperative Wong-Baker faces scale Postoperative pain and discomfort score scale
Detailed description:
It is a randomized, double blind study, involving 80 children with ages from 1 to 10 years
old, submitted to urogenital surgery, under general anesthesia and caudal block. The
patients will be divided into 4 groups: bupivacaine alone, bupivacaine plus clonidine,
bupivacaine plus morphine, bupivacaine plus clonidine and morphine. The peroperative
consumption of analgesics and inhaled gases, BIS, heart rate and arterial blood pressure
will be recorded. Postoperative pain will be evaluated by using Wong-Baker faces scale and
pain and discomfort score scale, as well as the consumption of analgesics.
