Vitamin D deficiency, frequently observed in pregnant women, is associated with altered vascular function and potential hemodynamic instability. This prospective observational study aims to investigate whether vitamin D deficiency is associated with an increased incidence and severity of spinal anesthesia-induced hypotension in pregnant women undergoing elective cesarean delivery. Vitamin D levels will be measured preoperatively, and intraoperative hemodynamic parameters will be closely monitored. The findings could contribute to improved management strategies for pregnant patients at risk of severe hypotension.",[62,63,64],"Spinal Anesthesia-induced Hypotension","Vitamin D Deficiency","Cesarean Section","2026-01-02",{"date":67,"type":68},"2026-01-06","ACTUAL",{"date":70,"type":68},"2025-03-01",{"date":72,"type":57},"2025-12-30",{"name":5,"class":6},1]
