Comparison Between Magnesium Sulfate and Dexmedetomidine in Controlled Hypotension During Functional Endoscopic Sinus Surgery: A Double-blind, Randomized Clinical Trial
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.
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.
