Brain Relaxation With Mannitol and Furosemide

• Status: Completed
• Trial end date: 2015-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Although mannitol is used for brain relaxation during neurosurgery and in the treatment of raised intracranial pressure; there is not a consensus on its safe and effective dose, the duration of its administration and its use in combination with loop diuretics. This study aimed to compare the effects of the mannitol alone and in combination with furosemide in different doses, on the brain relaxation, electrolyte, lactate levels of the blood, peroperative fluid balance and the volume of the urine in supratentorial mass resection surgeries.

This prospective, randomized, double blind, placebo controlled study included fifty one patients (ASA I-III) scheduled for elective supratentorial mass resection surgery. The patients were randomized into three groups for investigation of the effects of mannitol alone and in combination with furosemide in different doses. Blood sodium, potassium, chlorine, lactate, urine and osmolarity levels were recorded. The brain relaxation score (BRS) was evaluated twice by the surgeon using a 4 point scale (1=very good, 2=good, 3=bad, 4=very bad); at dura opening, and 30 minutes after the administration of the study drug.
