Reply: Only with an optimal position of the supraglottic airway in situ, valid conclusions can be drawn about oropharyngeal airway pressure

摘要

We would like to thank Van Zundert et al. for their interest in our article.[1]They have highlighted a very important point regarding confirmation of the optimal position of the supraglottic airway before measuring the oropharyngeal airway pressures.[2]We agree that confirmation of the optimal position is mandatory, but we believe the definition of optimal placement of supraglottic airway device (SAD) in adults cannot be applied in children.This can be attributed to the difference in the airway anatomy of children and adults. Our study was conducted on children between 10 and 30 kg. In contrast to the fibreoptic view seen in adults, where the perfect view denotes no view of the epiglottis, very often the epiglottis is seen hanging over through the aperture of the SAD in children.
