Brief Title: Evaluation of the Bonfils Fiberscope for Predicted Difficult Intubation in Awake Patients With Ear, Nose, and Throat (ENT) Cancer (INVIBO)
Official Title: INVIBO: Evaluation of the Feasibility and Tolerance of an Intubation Procedure Performed by Means of the Bonfils Fiberscope in Awake Patients With Predicted Difficult Intubation in the Context of ENT Cancer Surgery
Study ID: NCT01070537
Brief Summary: The Bonfils intubation fiberscope (BF), a rigid medical device with a curved tip, is exclusively used in anesthesiology for orotracheal intubation (OTI). The objective of the study was to evaluate the feasibility and the tolerance of an intubation procedure realized by means of the BF (BFI) in awake adult patients with predicted difficult intubation (PDI), in the context of ENT cancer surgery. The intubation is performed under local anesthesia (either nasal, oral, or intercricothyroidal) and sedation using Remifentanyl (AIVOC) with spontaneous ventilation. The primary endpoint is the rate of BFI meeting quality requirements: the procedure must be both successful (≤ 2 attempts and duration \< 180 sec) and well tolerated (Fahey score \< 2). The secondary endpoints include the difficulties met by the operator during the BFI and patient's perception of the intubation procedure, evaluated in the recovery room and 7 days after the intervention. Sample size is calculated using a one-stage Fleming design with p0=80%, p1=95%, alpha=5% and 80% power, for a total of 32 evaluable patients.
