Preoperative Shock Indexes and Post-Spinal Hypotension in Cesarean Surgery

This prospective observational study aims to evaluate the predictive performance of preoperative Shock Index (SI) and Modified Shock Index (MSI) for hypotension following spinal anesthesia in elective cesarean surgery. Post-spinal hypotension is a common complication that can affect maternal and fetal outcomes, and early identification of at-risk patients is essential for effective perioperative management.
