研究概览
简要总结
The study compares the incidence of pharyngolaryngeal complications in patients managed with either a pressure-limiting strategy using the AES Ultra CPVTM or a standard practice using a LMA, in ambulatory surgery patients.
详细描述
Recent evidence suggests that reduction of LMA intracuff pressure may decrease the incidence of pharyngolaryngeal symptoms. Yet, pressure manometers are not widely available limiting the application of a strategy of intracuff pressure reduction. The Ultra airway has been designed to provide continuous indication of intracuff pressure and can limit the intracuff pressure to < 60 cm H2O. This study compares the incidence of pharyngolaryngeal complications in patients managed with either a pressure-limiting strategy using the Ultra or a standard practice using a LMA, in ambulatory surgery patients.
