The Role of Serotonin in Intensive Care Patients (SERO-22)

27. maj 2022 opdateret af: Morten Rostrup, Oslo University Hospital

The Role of Serotonin in Respiratory and Circulatory Failure in Intensive Care Patients

Sepsis, cardiac arrest and multiple trauma are potentially life-threatening conditions and common reasons for intensive care unit (ICU) admission. The aim of this study is to investigate the role of the signaling substance serotonin in blood in these conditions.
