Objective: To explore the effects of fiber bronchoscope( FOB) and Lightwand wand on the hemodynamics of patients with difficult tracheal intubation through the mouth. Methods: Fifty patients with difficult airway treated with surgery through tracheal anesthesia were randomly divided into FOB group( F group) and Light wand group( L group). The systolic pressure,diastolic blood pressure,heart rate,pulse oxygen saturation in two groups were observed before anesthesia induction( T0),before intubation( T1),endotracheal intubation( T2),and at 1 minute( T3),3 minutes( T4) and 5 minutes( T5) after intubation,and the total time of endotracheal intubation,successful intubation cases and postoperative complications in two groups were recorded. Results: The endotracheal intubation success rate in F group and L group were 100. 0% and 92. 0%,respectively,the difference of which had no statistical significance( P 0. 05). The differences of the incidences of postoperative voice hoarse and sore throat between two groups had no statistical significance( P 0. 05). The total time of endotracheal intubation in F group was significantly less than that in L group( P 0.05),the DBP and HR value in F group were significantly lower than those in L group at T2and T3( P 0.05 to P 0.01).Conclusions: Compared with Lightwand,the effect of FOB on hemodynamics is smaller. Both FOB and Lightwand are effective methods to solve the difficult tracheal intubation.
