Ultrasonographic Optic Nerve Sheath Diameter in Postdural Puncture Headache Diagnosis

NCT07100158 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 176

No results posted yet for this study

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.
