The Effect of a Laryngeal Mask Airway on Optic Nerve Sheath Diameter
Recruiting
- Conditions
- Intracranial Pressure Increase
- Interventions
- Other: optic nerve sheath diamater
- Registration Number
- NCT06403592
- Lead Sponsor
- Erasmus Medical Center
- Brief 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.
