Open Access Abstract Introduction A limitation of pre-hospital monitoring is that vital signs often do not change until a patient is in a critical stage. Blood lactate levels are suggested as a more sensitive parameter to evaluate a patient s condition. The aim of this pilot study was to find presumptive evidence for a relation between pre-hospital lactate levels and in-hospital mortality corrected for vital sign abnormalities. Methods In this prospective observational study n 124 patients who required urgent ambulance dispatching and had a systolic blood pressure below 100 mmHg a respiratory rate less than 10 or more than 29 breaths minute or a Glasgow Coma Scale GCS below 14 were enrolled. Nurses from Emergency Medical Services measured capillary or venous lactate levels using a hand-held device
