About this study
The use of increasing doses of clonidine ssociated to bupivacaine in caudal epidural block provides better postoperative analgesia compared whit analgesia provide by bupivacaine alone
It is a randomized, double blind study, involving 80 children with ages from 1 to 10 years old, following eletive hypospadias surgery, under general anesthesia and caudal epidural block . The patients will be divided into 4 groups: bupivacaine alone, bupivacaine plus clonidine 1mcg/kg, bupivacaine plus clonidine 2 mcg/kg, bupivacaine plus clonidine 3 mg/kg. The peroperative consumption of anesthetics gases, heart rate and arterial blood pressure will be recorded. Postoperative pain will be evaluated by using FLACC scale ( faces , legs, activity , cry , consolability ) . Requiriments for supplementary postoperative analgesia at 24 h will be avaiable.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Clonidine 1 mcg/Kg, Clonidine 2 mcg/ Kg and Clonidine 3 mcg/ Kg in people with Postoperative Pain, run by Federal University of Minas Gerais.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 May 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Analgesia and efficacy of a bupivacaine-clonidine mixture measured through postoperative morphine consumption (time frame: 24 hours after the surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02769390, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2016; AzTrials last refreshed its copy on 8 Nov 2026.
