BackgroundThe Gldiescope video laryngoscope (GVL) as a recent intubating device has gained much popularity in difficult intubation over the last decade. It can be used as a substitute to flexible fiber optic bronchoscope (FOB) in intubating challenges. The object of this study is to compare the utility of GVL and FOB for intubating time, attempts, effects on hemodynamics, adverse effects, patient satisfaction and post intubation neurological outcome during awake intubation in traumatic cervical spine injury.MethodsFifty patients undergoing post traumatic cervical spine fixation under general anesthesia were randomly allocated to two groups in a prospective, controlled non-blinded study. All patients were premedicated with glycopyrrolate 0.2 mg iv and midazolam 1 mg iv that be repeated up to 0.05 mg/kg followed with a bolus dose of remifentanil 1.5 μg/kg then a continuous remifentanil infusion of 0.15 μg/kg/min for 3 min before procedure. Each patient underwent a wake endotracheal intubation with either GVL (G group) or FOB (F group) with manual in line stabilization (MILS). Intubating time, intubating attempts, hear rate (HR), mean arterial pressure (MAP), oxygen desaturation (SO2 < 90%), sore throat, patient satisfaction and postintubation neurological outcome were recorded.ResultsIntubating time was significantly lower in G group compared with F group (26 ± 5 versus 72 ± 11 respectively), while the percentage of the first successful intubating attempt was insignificantly higher in G group (88%) than in F group (72%). Both HR and MAP were significantly increased only in F group during intubation in comparison with the basal line values. Both devices were safe for post neurological outcome. No significant differences of adverse effects or patient satisfaction were recorded between groups.ConclusionThe GVL is a safe surrogate for FOB during awake intubation for post traumatic cervical spine fixation.
