Clinical research of using intratracheal intubation with flberoptic bronchoscope and GlideScope video laryngoscope in the thyroid surgeries under general anesthesia

Objective To research the hemodynamic responses and complications of orotracheal intubation with fiberoptic bronchoscope(FOB) and GlideScope video laryngo-scope(GSVL).Methods Eighty American Society of Anesthesiologists(ASA) grade Ⅰ—Ⅲ patients(34 male,46female)aged 23 — 70 yrs weighing 42 — 112 kg scheduled for thyroid surgery under general anesthesia with tracheal intubation were randomly divided into 2 groups(n = 40 for each group):FOB group and GSVL group.After induction of anesthesia,orotracheal intubation was performed with FOB or GSVL.Noninvasive blood pressure(BP),heart rate(HR) and bispectral index(BIS) were recorded at the time before induction,the time before and the time of tracheal intubation,and at 1,2,3,5,10 min after tracheal intubafion completed to observe the hemodynamic response and complications of the intratracheal intubation.Results The hemodynamic responses to intubation were not significantly different between GSVL group and FOB group,but compared with GSVL group,FOB group had higher one-time success rate and shorter intubation time was.There were less complications of intubation observed in FOB group compared with GSVL group.Conclusion FOB and GSVL can both prevent the hemodynamic responses to intubation,and FOB has advantage in improving one-time success rate and reducing complications produced by intubation.
