Summary

This study aims to investigate the relationship between spinal needle size and optic nerve sheath diameter (ONSD) in patients who develop post-dural puncture headache (PDPH) after spinal anesthesia. ONSD is measured using ultrasound, which helps estimate changes in brain pressure. The study also examines whether the severity of headache is related to ONSD. Adult patients aged 18 to 75 years who develop PDPH will be included. This research will be conducted at Konya City Hospital and is expected to last for approximately six months.

Detailed description

This prospective observational study investigates the relationship between spinal needle gauge and optic nerve sheath diameter (ONSD) in patients who develop post-dural puncture headache (PDPH) following spinal anesthesia. ONSD is measured using ultrasound as a non-invasive marker of intracranial pressure. The study also aims to evaluate the association between headache severity, assessed by the Visual Analog Scale (VAS), and ONSD values. Patients aged 18-75 years with PDPH will be included, and data on spinal needle gauge, ONSD, and VAS scores will be analyzed. The study is being conducted at a single tertiary care center and aims to contribute to understanding the physiopathology of PDPH and its relation to procedural factors.
