Simplification and Implementation of Awake Fibreoptic Orotracheal Intubation

Simplification and Implementation of Awake Fibreoptic Orotracheal Intubation

Awake fibreoptic intubation (AFOI) is a classic and standard method for some special patients which is also difficult for anesthesiologists to learn and master. The procedure is sometimes hard and often takes about 20-30 min. Most of patients have a strong sense of discomfort. Investigators conducted the research to study the simplification and feasibility of AFOI.

Many studies have studied the sedative drugs and regional anesthesia related to awake intubation. However, several problems of AFOI are existing including long operation time, patients' strong discomfort, coughing and resistance. And, to investigators' knowledge, there was a lack of a fixed procedure for the implementation of AFOI. Investigators conducted the research and aimed to study the simplification and feasibility of a new AFOI method based on years of clinical theory, practice and experience.
