简要总结
The goal of this observational trial is to study the effect of a laryngeal airway mask on the optic nerve sheath diameter, as a surrogate for intracranial pressure.
The optic nerve sheath diameter of participants will be measured under general anesthesia, before, during and after insertion of a laryngeal airway mask.
