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.

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.

Inclusion criteria
18 and 65 years scheduled for functional endoscopic sinus surgery
Exclusion criteria
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.
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.
Other names: Precedex
Time frame: every 5 minutes during surgery up to 60 minutes
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
Time frame: up to 24 hours
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.
