BackgroundFiberoptic intubation is the gold standard technique for difficult airway management in patients of temporomandibular joint. This study was aimed to evaluate the clinical efficacy and safety of dexmedetomidine as premedication with propofol infusion for fiberoptic intubation.MethodsConsent was obtained from 46 adult patients of temporomandibular joint ankylosis, scheduled for gap arthroplasty. They were enrolled for thisdouble-blind, randomized, prospective clinical trial with two treatment groups - Group D and Group P, of 23 patients each. Group D patients had received premedication of dexmedetomidine 1 μg/kg infused over 10 min followed by sedative propofol infusion and the control Group P patients were given only propofol infusion to achieve sedation. Condition achieved at endoscopy, intubating conditions, hemodynamic changes and postoperative events were evaluated as primary outcome.ResultsThe fiberoptic intubation was successful with satisfactory endoscopic and intubating condition in all patients. Dexmedetomidine premedication has provided satisfactory conditions for fiberoptic intubation and attenuated the hemodynamic response of fiberoptic intubation than the propofol group.ConclusionFiberoptic intubation was found to be easier with dexmedetomidine premedication along with sedative infusion of propofol with complete amnesia of the procedure, hemodynamic stability and preservation of patent airway.
