Optic Nerve Sheath Diameter for Predicting Post-Dural Puncture Headache in Cesarean Section Patients

NCT07497945 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 220

Last updated 2026-03-27

No results posted yet for this study

Summary

Some patients develop headache after spinal anesthesia used during cesarean section. This condition is called post-dural puncture headache (PDPH). Early identification of patients at risk may improve patient care.

This study evaluates whether optic nerve sheath diameter (ONSD), measured using a non-invasive bedside ocular ultrasound technique, can help predict the development of PDPH.

Participants undergoing cesarean section with spinal anesthesia will undergo ONSD measurements at predefined perioperative time points. Participants will be followed postoperatively for the occurrence of headache.

The findings may help improve early recognition and management of PDPH.

Conditions

  • Post Dural Puncture Headache

Interventions

OTHER

Optic Nerve Sheath Diameter Measurement

Participants will undergo non-invasive ocular ultrasound measurement of optic nerve sheath diameter at five predefined time points: preoperatively, 10 minutes after spinal anesthesia, at the end of surgery, at postoperative 24 hours, and at postoperative 48 hours.
