Official Title: The Diagnostic Value of Ultrasonographic Optic Nerve Sheath Diameter Measurement in Postdural Puncture Headache
Brief Summary:
This study aims to investigate the hypothesis that ultrasonographic optic nerve sheath diameter (ONSD) measurement can help predict the development and severity of postdural puncture headache (PDPH) in patients undergoing spinal anesthesia for total knee arthroplasty.PDPH is defined as a headache that worsens in an upright position and improves while lying down.
