Randomized Controlled TrialInfluence of LMA cuff pressure on the incidence of pharyngolaryngeal adverse effects and evaluation of the use of manometry during different ventilation modes: A randomized clinical trial.
Pharyngolaryngeal discomfort is a significant complication following the use of laryngeal mask airway (LMA). The present study aimed to investigate the relation of LMA cuff pressure and the occurrence of pharyngolaryngeal discomfort during spontaneous ventilation (SV), pressure support (PSV) and pressure control ventilation (PCV). ⋯ Maintaining LMA cuff pressure in values which do not exceed 60 cmH2O probably contributes in decreasing pharyngolaryngeal discomfort independently of ventilation mode. The ventilation mode which leads to the highest incidence of pharyngolaryngeal morbidity when cuff pressures are not closely monitored is PSV.
