Summary

The purpose of the study is to compare effectiveness of different methods of achieving oxygenation in obstructive sleep apnea patients. The investigators intend to compare transnasal humidified rapid-insufflation ventilator exchange (THRIVE) combined with nasopharyngeal airway with THRIVE alone.

Detailed description

With the increasing prevalence of obesity, the prevalence of OSA is also rising, ranging from 9% to 25% in the general adult population. Patients with OSA have features of an anatomically tricky airway due to a crowded collapsible pharyngeal space, compounded by physiological problems related to lower functional residual capacity and increased oxygen consumption, leading to faster oxygen desaturation. Meanwhile, patients with OSA, compared to patients without OSA, have a 3-4 times higher risk of difficult intubation, difficult mask ventilation, or both. Apnoea time is a potentially hazardous period during induction of anesthesia and it is particularly so in patients with OSA. OSA patients undergoing general anesthesia gave rise to many concerns and challenges, and strategies to extend the apneic time were required. Identifying the most effective method of oxygenating OSA patients can therefore significantly improve the safety of delivering general anaesthesia to these patients.
