Details and patient eligibility

About

Rationale: Delivery dry gas during anesthesia is associated with post-operative sore throat (POST). Oxygen nebulizer therapy increases humidity to the airway, especially post-extubation.

Objective: To investigate the effect and complications of oxygen nebulizer therapy on POST.
