A STUDY ON CORRELATION BETWEEN MODIFIED SHOCK INDEX AND SERUM LACTATE VALUES

Abstract

INTRODUCTION: The Modied Shock Index is a test to identify occult shock in a patient with a normal blood pressure. High Lactate levels have been validated to identify the degree of shock and also response to resuscitation. The shock index (SI) is a bedside assessment dened as heart rate divided by systolic blood pressure, with a normal range of 0.5 to 0.7 in healthy adults. METHODOLOGY: Demographic data like age and sex was obtained. The patients were evaluated clinically, history and hemodynamic were noted. ABG was done on the patients and lactate levels were recorded. Requirement of Inotropic support, mechanical ventilation and dialysis were noted. All the ndings were recorded on a predesigned and prepared proforma. The Modied Shoc RESULTS: k Index was split into three categories: <0.7, 0.7-1.3 and >1.3. The mean lactate in the <0.7 group, 0.7-1.3 group and the >1.3 group were 5.5000, 3.7060 and 4.8616 respectively. A Tukey post hoc test revealed that patients with modie CONCLUSION: d Shock Index >1.3 had statistically signicantly higher Lactate levels (5.729±2.846, p = 0.000) than patients with modied Shock Index 0.7 – 1.3 (3.706±1.520).
