The Effect of a Laryngeal Mask Airway on Optic Nerve Sheath Diameter
Sponsor
Erasmus Medical Center
Enrollment
230 participants
Start Date
Mar 25, 2024
Study Type
OBSERVATIONAL
Conditions
Summary
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.
Eligibility
