Effect of diffusion of anaesthetic gases on fibre-optic view change of laryngeal mask airway and post-operative laryngo-pharyngeal morbidity in children – A randomised controlled trial

Abstract: Background and Aims: The diffusion of nitrous oxide (N 2 O) into the air-filled cuff of the classic laryngeal mask airway (LMA) may lead to an increase in cuff pressure (CP) and displacement of LMA affecting its performance. This study was conducted to evaluate the change in optimal position of LMA by fibre-optic bronchoscope, the changes in cuff pressure and oropharyngeal leak pressure (OLP), and post-operative laryngo-pharyngeal morbidity during N 2 … Show more

“…PLMA has been used successfully in the lateral position with minimal dislodgement rates. [ 4 5 ] However, the oropharyngeal sealing pressure of PLMA can decrease in the lateral position in children. [ 6 ] In an event of dislodgement, rescue measures should include deepening the plane of anaesthesia, repositioning of LMA, and if not successful, LMA may be removed and ET can be passed with BB in situ.…”
