Summary

Ultrasonography(USG)-guided optic nerve sheath diameter measurement and its correlation with brain computed tomography in the evaluation of intracranial pressure in patients who underwent intracranial brain tumor surgery.

Detailed description

Optic Nerve Sheath Diameter (ONSD) Measurement is a non-invasive diagnostic method used to detect increased intracranial pressure, and in general, ONSD measurement over 5 mm has been found to be associated with increased intracranial pressure.ONSD will be measured using an USG device within the specified time periods. T0: Before anesthesia induction T1: First 5 minutes immediately after induction of anesthesia T2: At the end of the surgery before extubation /minute T3: Within the first hour/minute after extubation T4: 12 hours/minute after tumor resection T5. 24 hours/minute after tumor resection ONSD measurement in brain computer tomography (BCT); Eyeball diameter and optic nerve diameter measurements will be made on BCT transverse images at the optic nerve level and recorded.In patients, USG and BCT correlation comparison is planned before the operation (T0), in the first hour after the end of post-operative surgery (T3) and at the 24th hour after post-operative surgery (T5). T0: ONSD measurement in pre-operative Brain CT T3: BCT ONSD measurement/minute within the first hour following the postoperative period T5: BCT ONSD measurement/minute 24 hours following the postoperative period

Conditions

Interventions

Type	Name	Description
PROCEDURE	USG	The aim of this study is to measure the intracranial pressure of patients planned for brain tumor surgery by measuring the optic nerve sheath diameter (ONSD) under USG guidance and compare its correlation with the computed brain tomography.
PROCEDURE	BCT	The aim of this study is to measure the intracranial pressure of patients planned for brain tumor surgery by measuring the optic nerve sheath diameter (ONSD) under USG guidance and compare its correlation with the computed brain tomography.
