Fiberoptic bronchoscope guided intubation is an important method of difficult airway management. The use of specific airways has been devised to assist the fiberoptic intubation. The authours compared effectiveness of separated airway with fiberoptic bronchoscope guided intubation and the hemodynamic responses.
104 adult patients of American Society of Anesthesiologists grading (ASA) I-II who scheduled for surgery under general anesthesia were randomly divided into the Laryngoscope group (L group, n = 30) or the Fiberoptic bronchoscope group (F group, n = 36) or the Fiberoptic bronchoscope with separated airway (MF group, n = 38). A Fiberoptic bronchoscope guided intubation and a fiberoptic bronchoscope with separated airway and a direct laryngoscope was performed after inducing anesthesia. Intubation time, Jaw thrust incidence, mean blood pressure and heart rate after anaesthesia induction, at intubation and every two minute for a further 7 min were recorded.
The intubation time was significantly shorter in the MF group (58.3 +/- 13.7 sec) than F group (71.9 +/- 22.1 sec). Jaw thrust incidence was lower in the MF group (60.5%) than F group (100%). The changes of MAPs and HRs during the observation were not significantly different in three group.
Fiberoptic intubation using separated airway reduced intubation time and the incidence of jaw thrust.
