Summary
This study tested whether measuring the optic nerve sheath with ultrasound can predict postdural puncture headache (PDPH) after spinal anesthesia. 176 adults having knee replacement surgery were scanned before and after the procedure. The goal was to see if changes in nerve sheath diameter could identify who would develop a headache that worsens when sitting or standing.
