Mortality in Critically Ill Patients: A Prospective Observational Study
Abstract: Background: Serum lactate is an important biomarker of tissue hypoxia, impaired perfusion, and disease severity in critically ill patients. Elevated lactate levels have consistently been associated with increased morbidity and mortality in intensive care unit (ICU) patients. Early identification and serial monitoring of hyperlactatemia may facilitate risk stratification and timely intervention. Our aim to evaluate the correlation between serum lactate levels and mortality among critically ill patients admitted to the ICU. Materials and Methods: This prospective observational study was conducted in the ICU of a tertiary care teaching hospital over six months. One hundred critically ill adult patients were enrolled. Admission serum lactate was measured through arterial blood gas analysis. Patients were categorised into Group 1 ( 4 mmol/L. Patients with elevated lactate more frequently required mechanical ventilation (76.3% vs 38.7%; p
