Introduction: Anaesthetists may be called upon to emergently secure the airway of a laterally positioned patient. Intubating a patient's trachea in the lateral position may be difficult due to unfamiliarity. This exploratory study aimed to investigate the success rate of lateral intubation performed by novices in a controlled setting.Methods: In this observational study, all patients who presented for elective surgery requiring the lateral position with planned lateral intubation at Singapore General Hospital were included. The trainee assigned to each patient had no prior indication of the proposed lateral intubation until the start of the case. Verbal instructions were given before the start of and during the procedure. The consultant anaesthetist in attendance could intervene at any point to prevent patient harm or if the trainee requested assistance. Time to intubation, adjuncts used and complications encountered were recorded.Results: A total of 44 consecutive patients were included in this study. The trainees completed 42 of the 44 lateral intubations, with 41 being successfully performed on the first attempt. All patients were intubated successfully in a lateral position within two attempts. The mean duration of intubation was 57.3 ± 36.4 seconds. There was no difference between left and right lateral intubation. Other than one episode of transient desaturation on pulse oximetry, there were no complications.Conclusion: Lateral intubation by trainees had a high success rate when supervised by an experienced operator. Intubation of patients in unconventional positions using routine airway equipment should be included in airway training for trainees. [ABSTRACT FROM AUTHOR]
