What this trial studies

This observational study aims to investigate how altitude affects the incidence and severity of post-dural puncture headache (PDPH) in parturients undergoing spinal anesthesia for cesarean delivery. Conducted in Nepal, the study compares outcomes between high-altitude (Jumla) and low-altitude (Dharan) settings. Eligible participants will be screened based on specific criteria, and their baseline characteristics, including anxiety and chronic pain conditions, will be recorded. The diagnosis of PDPH will follow the international headache society's criteria.

Who should consider this trial

Good fit: Ideal candidates are parturients aged 18 and older, native to their resident altitude, and scheduled for cesarean delivery with spinal anesthesia.

Not a fit: Patients with hypertensive disorders, cerebrovascular diseases, or those requiring general anesthesia due to failed spinal anesthesia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how altitude influences PDPH, potentially guiding better management strategies for parturients.

How similar studies have performed: While studies on PDPH exist, this specific investigation into altitude effects is novel and has not been extensively tested.
