Abstract:
Objective To evalute the combination of dexmedetomidine and fentanyl in sedation during awake nasotracheal fiberoptic intubation. Methods One hundred and twenty ASAⅠ or Ⅱ patients scheduled to receive general anesthesia were randomly divided into 3 groups (n = 40 in each group). Patients in group L received an infusion of 1 μg/kg dexmedetomidine,patients in group H received an infusion of 2 μg/kg dexmedeto-midine ,and patients in group DF received an infusion of 1 μ g/kg dexmedetomidine added to 1 μ g/kg fentanyl. Nasotracheal intubation was performed after complete topical anesthesia. HR and MAP were recorded before anes-thesia(baseline,T0),before intubation(T1)and immediately after intubation(T2),respectively. The intubation score(vocal cord movement,coughing and limb movement),fiberoptic intubation score,nasotracheal intubation score and airway obstraction score were assessed in all aptients. On the first post-operative day,recall,adverse events and satisfaction score were also assessed. Results HR and MAP at T1 in three groups were significantly lower than those at T0(P < 0.05,respectively ). HR and MAP at T2 in group L were significantly higher than those in group H and DF(P<0.05,respectively). More incidence of vocal cord closed,severe cough,severe limb movement,heavy grimacing,defensive movement of head and hands after nasotracheal intubation were observed in group L than those in the other two groups. The incidence of airway obstraction and bradycardia in group H were higher than those in group L and DF. Patients in group L had lower postoperative satisfaction scores. Conclusion Adding 1 μg/kg fentanyl to 1 μg/kg dexmedetomidine is a good method for awake nasotracheal fiberoptic intuba-tion,which can prevent the risk of airway obstruction associated with the increase of dexmedetomidine dose,with the achievement of the same favorable sedation.
