Diastolic Shock Index for Predicting Postspinal Hypotension
Sponsor: Istinye University
Summary
This prospective observational study aims to evaluate the diagnostic performance of the preoperative Diastolic Shock Index in predicting postspinal hypotension and to compare its performance with other shock indices, including the Shock Index, Modified Shock Index, and Age Shock Index. The study will include patients aged 50 years and older undergoing elective unilateral inguinal hernia surgery under spinal anesthesia. Hemodynamic parameters will be recorded before and after spinal anesthesia as part of routine clinical monitoring. The primary outcome is the development of postspinal hypotension. Secondary outcomes include vasopressor requirement, total ephedrine dose, lowest intraoperative mean arterial pressure, and the diagnostic performance of the evaluated shock indices using receiver operating characteristic curve analysis. No additional intervention beyond routine anesthetic and perioperative care will be performed for study purposes.

Conditions
Interventions
Spinal Anesthesia
Spinal anesthesia will be administered as part of routine clinical care for elective unilateral inguinal hernia surgery. The study will not modify the anesthetic management or introduce any additional intervention for research purposes. Hemodynamic parameters obtained during routine perioperative monitoring will be recorded to evaluate the development of postspinal hypotension.
