Scientific titleEffect of laryngeal mask airway (LMA) in small airway function in the postoperative period compared with the endotracheal tube (ETT)
Study objectivesTo compare the effect of laryngeal mask airway versus end tracheal tube on small airway function in the post operative period.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSurgery: Small airway function
InterventionPatients will be randomised to either LMA or ET for anaesthesia.
Intervention typeProcedure/Surgery
Primary outcome measure(s)

Changes in airway resistance in the lung.

Key secondary outcome measure(s)

If there are marked differences it will add a new dimension to the choice of airway device used in patients with constrictive/obstructive airways disease.

Key inclusion criteria1. ASA Grades 1 or 2 (ie healthy patients of patients with well controlled chronic conditions) for elective surgery expected to last >30mins, on peripheral or body surfaces. We expect this would mean mainly orthopaedic or plastic surgery patients but could include vascular (varicose veins)

4. Patients consenting to the research
5. No history of gastric reflux
Key exclusion criteria1. ASA 3 or higher
