There are only few studies assessing the prognostic value of blood lactate values on the outcome of high-risk, haemodynamically stable, trauma patients. A systematic, rapid & accurate field triage is necessary. Evidence is limited to suggest that tissue hypo perfusion & ischemia are limited to patients with SBP< 90mmHg. Recent studies shown that Systolic BP of less than 110 mm Hg may more accurately reflect the first physiologic response of shock. Data collection was started after obtaining clearance from the Institution Ethical Committee. Informed consent was taken from study participants. After explaining the purpose of the survey, data was collected from all patients regarding personal information like age and gender. Vital signs (Pulse Rate, Blood pressure, Respiratory Rate and Temperature) and Parameters like Urine output and Saturation at room air were measured. Serum lactate levels were measured at the time of admission and after 1-6 days of the surgery. Systolic and Diastolic blood pressure is negatively correlated with serum lactate levels during admission, i.e, lower the systolic and Diastolic blood pressure higher is the serum lactate levels. It was found statistically highly significant. Pulse rate and Respiratory rate were positively correlated with the serum lactate levels during admission, i.e, lower the pulse rate and respiratory rate higher will the serum lactate levels. It was found statistically highly significant.
