The use of airtraq oPtical laryngoscoPe in unanticiPated difficult tracheal intubation of 20 Patients / 中国综合临床

ABSTRACT

Objective To summarize the experiences usinG the Airtraq optical larynGoscope( AL)in the manaGement of unanticipated difficult endotracheal intubation. Methods Twenty surGical patients with General anesthesia usinG tracheal intubation were induced with propofol-remifentanyl and injected with atracuriun (0. 5 mG/kG). And then,larynGoscope with Macintosh directly throuGh oral tracheal intubation,and located the tracheal intubation by end tidal carbon dioxide detection method. AttemptinG oral tracheal intubation with Macintosh larynGoscope were failed for twice time,the AL was used to accomplish tracheal intubation. Results In all the patients,tracheal intubations with AL as a rescue intubation device Got clear GradeⅠCormack-Lehane Glottis exposure,with once-time successful intubation attemptinG in l8 patients. But in other 2 patients,tracheal intubations were accomplished by combined use of a fibreoptic bronchoscope which GuidinG tracheal tube into the Glottis throuGh AL after tracheal tube slidinG backward into the esophaGus repeatedly. DurinG the intubation attempts,interval mask ventilation were Given maintaininG SaO2≥90% in all patients. Conclusion AL offers an new effective technique as a rescue airway device in deal with unanticipated difficult tracheal intubation.
