Measurement of lactate in a prehospital setting is related to outcome

Objective We evaluated the relationship of lactate measured in a preclinical setting with outcome. Simultaneously, we evaluated the feasibility of implementing blood lactate measurement in a prehospital setting as part of a quality improvement projectMethods Chart review of patients from whom serum lactate levels prospectively were obtained in a prehospital setting. Total population was divided into two groups, that is, a shock group and a non-shock group according to the predefined shock symptoms. The shock group was divided into two groups, that is, a lactate less than 4 mmol/l (subgroup 1) and a lactate of at least 4 mmol/l (subgroup 11).Results In about 50% of possible cases, lactate was measured in the prehospital setting. Median lactate in subgroup I (n=74) was 3.2 (1.5-3.9) mmol/l versus 5.0 (4.0-20.0) mmol/l in subgroup I I (n = 61) (PConclusion Implementation of lactate measurement in prehospital setting is feasible, and potentially clinical relevant. Lactate measured in a preclinical setting is related to outcome. Subsequent studies should evaluate whether treatment of shock patient Is based on prehospital lactate measurement will improve outcome.
