About this study
Official title: Comparison Between Magnesium Sulfate and Dexmedetomidine in Controlled Hypotension During Functional Endoscopic Sinus Surgery: A Double-blind, Randomized Clinical Trial
It is very important to decrease the bleeding during functional endoscopic sinus surgery (FESS) in order to increase the visibility of the surgical site. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on visibility of surgical site.
Read the detailed description
Background: It is very important to decrease the bleeding during functional endoscopic sinus surgery (FESS) in order to increase the visibility of the surgical site. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on visibility of surgical site.
Methods: Sixty patients aged between 18-65 years were enrolled. Patients were divided into two groups. In the magnesium sulfate group (Group M) patients were administered 40 kg-1 magnesium sulfate in 100 ml saline solution in 10 minutes as IV loading dose 10 minutes before the induction and 10-15 mgkg-1hour-1 infusion during the surgery. In the dexmedetomidine group (Group D) patients were administered 1 µgkg-1 dexmedetomidine in 100 ml saline solution as loading dose 10 minutes before the surgery and 0.5-1 µgkg-1hour-1 dexmedetomidine during the surgery. Deliberate hypotension was defined as a mean arterial pressure (MAP) being 60-70 mmHg.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Magnesium SulfateDrug
40 mg kg-1 IV magnesium sulfate (OSEL ilaç San. Ve Tic. A.Ş., Beykoz, Istanbul, Turkey) in 100 ml saline solution was applied to patients in Group M as a loading dose 10 minutes before the induction and continued during the surgery at the dose of 10-15 mg kg-1hour-1.
DexmedetomidineDrug
Also called Precedex
1 µg kg-1 IV dexmedetomidine (Precedex Abbott Labs, North Chicago, IL) in 100 ml saline solution was applied to patients in group D 10 minutes before the surgery and continued during the surgery at the dose of 0.5-1 µg kg-1.

| Dexmedetomidine | Active comparator | 1 µg kg-1 IV dexmedetomidine (Precedex Abbott Labs, North Chicago, IL) in 100 ml saline solution was applied to patients in group D 10 minutes before the surgery and continued during the surgery at the dose of 0.5-1 µg kg-1. Receives: Drug: Dexmedetomidine |
What is being measured
The primary outcome is the main question the study is designed to answer.
visibility scale of the surgical site
Surgical site was rated according to 6 point scale at every 5 minutes by the same surgeon in terms of bleeding and dryness during surgery
Measured: every 5 minutes during surgery up to 60 minutes
Secondary outcomes (1)
Blood Pressure
After the patients were taken to the operating room, mean arterial pressure (MAP)was monitored and data was measured at every 5 minutes. Hemodynamic data were recorded at the initial phase, after the induction, 5, 10, 15, 30 and 45 minutes after the intubating, 1 and 5 minutes after the extubating.
Measured: up to 24 hours

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Magnesium Sulfate and Dexmedetomidine in people with Hemorrhage, run by TC Erciyes University.
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 1 inclusion and 3 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 8 Oct 2013. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
visibility scale of the surgical site (time frame: every 5 minutes during surgery up to 60 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 8 Oct 2013.
