Authors' conclusion

The LMA ProSeal provides higher OPLP than the i-gel at a 60° head-rotated position under general anesthesia.

Study context

As reported in the abstract

Secondary outcomes

Maximum pressure under volume-controlled ventilation (VCV) at 60° head rotation

Significantly higher with LMA ProSeal than i-gel

Expiratory tidal volume

LMA ProSeal: no significant change with head rotation; significantly higher than i-gel at 60° head rotation

Ventilation score and fibreoptic view of the vocal cords

Not significantly different between ProSeal and i-gel

Safety

Complications

Not significantly different between ProSeal and i-gel
