DO SHOCK INDEX, MODIFIED SHOCK INDEX, AND SHOCK INDEX BY AGE HAVE A PREDICTIVE VALUE IN DETERMINING THE RISK OF POST-SPINAL HYPOTENSION IN ELDERLY PATIENTS?

Abstract

Introduction: Intraoperative hypotension in the elderly, is associated with an increased risk of complications. Predicting intraoperative hypotension will help patients have better outcomes by providing early prevention and intervention. We investigated the predictive value of the shock index, modified shock index, and shock index by age to determine the risk of hypotension in elderly patients undergoing spinal anesthesia in minor elective surgeries. Materials and Methods: Our prospective observational study included 128 patients aged ≥65 with ASA classifications of I-III undergoing minor elective surgeries under spinal anesthesia lasting
