Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will aim to investigate whether systemic inflammatory markers-especially the neutrophil-to-lymphocyte ratio (NLR)-obtained from preoperative complete blood counts can predict the development of post-dural puncture headache (PDPH) in obstetric patients undergoing cesarean section under spinal anesthesia.
