Treatment and study plan

Ultrasound examination of the optic nerve sheath diameter

Diagnostic Test

The optic nerve sheath diameter is examined using ultrasonography.

    Time frame: At 1 minute after the induction of anesthesia and at 1 minute after the end of surgery

    The optic nerve sheath of each eye is observed using ultrasound, and the optic nerve sheath diameter is assessed after induction of anesthesia and at the end of surgery.

Secondary outcomes

  1. Optic nerve sheath diameter at each time point

    Time frame: At 1 minute after the induction of anesthesia and at 1 minute after the end of surgery

    The optic nerve sheath of each eye is observed using ultrasound, and the optic nerve sheath diameter is assessed after induction of anesthesia and at the end of surgery.

  2. Nausea and vomiting

    Time frame: At 1 hour after surgery

    Presence and severity of nausea and vomiting is assessed.
