Non-invasive Tool for Measuring Hemoglobin in Severe Trauma Patients in the ED

The development of miniaturized analytical technologies has facilitated the gradual decentralization of part of the laboratory examinations to the patient. In addition, investigators are currently seeing the development of tools for non-invasive measurement of certain biological parameters. Thanks to their ease of use, results are obtained almost immediately and with good performance. These "rapid" tests or techniques should, in theory, reduce the time taken to take charge of patients, particularly in emergencies or in critical situations where the therapeutic decision should be as rapid and efficient as possible. These means, by their ease and speed of results, could be associated with the clinical examination of the practitioner to increase his diagnostic performance.
