Clonidine and Morphine in Caudal Anesthesia - Full Text View

Purpose

Hypothesis: The combined use of Clonidine and Morphine in caudal anesthesia provides better postoperative analgesia than either drug alone after urogenital pediatric surgery.

Active Comparator: C compare caudal anesthesia with bupivacaine plus clonidine with caudal anesthesia with bupivacaine alone or in addition to morphine or morphine plus clonidine	Drug: Clonidine 1 mcg/kg
Active Comparator: M compare caudal anesthesia with bupivacaine plus morphine with caudal anesthesia with bupivacaine alone or in addition to clonidine or morphine plus clonidine	Drug: Morphine 20 mcg/kg
Active Comparator: CM compares caudal anesthesia with bupivacaine, morphine and clonidine with caudal anesthesia with bupivacaine alone or in addition to morphine or clonidine	Drug: Bupivacaine plus clonidine and morphine bupivacaine 0,166% 1 ml/kg clonidine 1 mcg/kg morphine 20 mcg/kg

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.
