DISSEMINATED INTRAVASCULAR COAGULATION ASSOCIATED WITH SEPTIC SHOCK
Conditions
Brief summary
Neutrophil fluorescence could be a reliable and early diagnostic marker of disseminated intravascular coagulation septic DIC, which can be used routinely. The objective of the investigators is to define the optimal threshold of neutrophil fluorescence associated with a sensitivity of at least 90% for the diagnosis of DIC.
Interventions
CBC performed on the background of an EDTA tube, collected routinely allowing neutrophil fluorescence measurements. This tube will then be passed over on the automaton for a CBC measurement with leukocyte differentiation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Define the optimal threshold for neutrophil fluorescence (measured at admission of the patient to intensive care on a new automaton) associated with a sensitivity of at least 90% for the diagnosis of disseminated intravascular coagulation DIC. | 1 month | DIC is diagnosed based on the ISTH score (reference diagnosis) on day 2: patients will be considered to have DIC if the score is positive within the first 48 hours after admission to the ICU. Neutrophil fluorescence is measured on a new automaton. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To estimate the performance indicators of neutrophil fluorescence measured a new automaton.at admission of the patient to the ICU for all relevant thresholds. | 1 month | Sensitivity (Se) |
| To compare the areas under the partial ROC (receiver operating characteristic) curve (for a sensitivity greater than or equal to 90%) illustrating the performance of neutrophil fluorescence measured at the patient's admission to the ICU in the diagnosis | 1 month | Area under the partial ROC curve (corresponding to a 90% ≥ Se) |
