Evaluation of the Effect on Optic Nerve Sheath Diameter in Patients Undergoing Cesarean Section — EONSDCS  

Intracranial Pressure Clinical Trial

Official title:
Evaluation of the Effect of Epidural Anesthesia on Optic Nerve Sheath Diameter in Patients Undergoing Cesarean Section

Clinical Trial Summary

Depending on the physiology of pregnancy, the risk of increased aspiration, difficult airway, increased oxygen consumption and reduced functional residual capacity, breathing problems make general anesthesia application risky. In obstetric operations, neuraxial anesthesia is preferred because of both maternal and maternal mortality and morbidity. Epidural area has decreased due to pregnancy physiology. Previous studies have shown that the blood given to the epidural area increases the intracranial pressure by compressing the dura mater.Optic nerve diameter measurements ultrasound guided is a non-invasive and reliable method for detecting intracranial pressure increase.

In this study, aimed to compare the optic nerve sheath diameter before and after epidural anesthesia with USG.

Clinical Trial Description

Epidural anesthesia will be performed at L2 level and sitting position in all patients. Patients will be measured and recorded for optic nerve sheath diameter at 15 min (T2), 30 min (T3) and 60 min (T4) immediately after epidural anesthesia (T0) and after epidural anesthesia.. Measurement of the optic nerve sheath diameter will be done with the help of a linear probe without applying high pressure to the eyeball while the patient is in supine position and the eyelids are closed. The optic nerve sheath diameter will be measured 3 mm beyond the optical disc. The measurements shall be applied in both transverse and sagittal planes for both eyes and the arithmetic mean of the four measured values. ;
