INFLUENCE OF HEAD AND NECK POSITION ON OROPHARYNGEAL SEAL PRESSURE AND VENTILATION USING BASKA MASK IN ANAESTHETIZED PARALYSED PATIENTS: A PROSPECTIVE RANDOMIZED CLINICAL TRIAL

Abstract :

Background: Changes in the shape of the pharynx with head and neck movement can alter the forces transmitted to the cuff along the airway device during ventilation which may lead to displacement of the device and airway leak. This study was designed to determine the effect of different head and neck positions on the oropharyngeal seal pressure and ventilation score using Baska mask in anaesthetized paralyzed patients. Methods: In this randomized prospective clinical trial, Baska mask was inserted in 35 anesthetized paralyzed patients, planned for various elective surgical procedures. The position of the head and neck was changed randomly from neutral to flexion (450 flexion of neck), extension (450 extension of neck) and lateral rotation (900 rotation of neck towards left). Oropharyngeal seal pressure, ventilation score, peak inspiratory pressure, expiratory tidal volume and end tidal carbon dioxide were measured in all positions. Results: As compared to neutral position, oropharyngeal seal pressure and peak inspiratory pressure were significantly higher during flexion and lower during extension but similar during lateral rotation of head and neck. Expiratory tidal volume and end tidal carbon dioxide did not change significantly with change of head and neck position. Ventilation score was comparable in all positions. Conclusion: Effective ventilation is possible in all positions of head and neck using Baska mask in anaesthetized paralysed patients. However, caution should be taken in the extreme flexion of head and peak inspiratory pressures need to be monitored
