Simplification and Implementation of Awake Fibreoptic Orotracheal Intubation

With forty patients (ASA I\~II, aged 18\~75, simulating cervical instability injury) recruited to be operated on under general anesthesia, two experienced anesthesiologists performed the whole procedures within the study. Pre anesthetic interview was taken to illustrate the procedures of tracheal intubation to the patients. The simplified method consisted of three parts: conscious sedation, regional anesthesia and intubation. The time of AFOI, rate of one-time intubation success, hemodynamic parameters, pulse oxygen saturation (SpO2), rate of amnesia of the intubation, patients' satisfaction, and relative complications were recorded accordingly.
