Modulation of Vasoreactivity in Septic Shock: Impact of Recombinant Protein C (PCA)
The purpose is to demonstrate that vasoreactivity of patients with septic shock evaluated with dose-response curve is diminished in septic shock and ameliorated by activated protein C (APC).
This amelioration is correlated to decrease of inflammation, decrease of reactive oxygen species (ROS) markers and increase of circulating catecholamines.

Beskrivelse
Inclusion Criteria:
- Patients with septic shock as determined by standard criteria (including infection and severe infection)
Exclusion Criteria:
- Pregnant women
- Absence of signed informed consent. Due to gravity of medical situation of patients, inclusion will be possible after informed consent of a family member. As soon as possible, an informed consent will be obtained by patient
- Contraindication to Xigris: evolutive internal bleeding , intracranial pathology, neoplasia or brain involvement, concomitant heparin therapy >= 15 IU/kg/h, known hemorrhagic diathesis except acute coagulopathy subsequent to sepsis, severe chronic liver disease, platelet count < 30000 x 10^6/L, high bleeding risk, known hypersensibility to drotrecogin alfa (activated), one of excipients or bovine thrombin

Andre navn:
After baseline measurement, cuff is blown up to obtain a muscular saturation at 40% and then deflated.
Reactive hyperthermia is measured.
It is considered as an index for endothelial function.
Continuous administration of phenylephrine with electric syringe with increasing dosing levels: 0.0; 0.02; 0.05; 0.1; 0.2; 0.5; 0.75; 1.00; 1.50; 3.00; 4.50; 6.00; 9.00 et 12 µg/kg/min. Each level is maintained for 5 minutes. Administration of phenylephrine is stopped progressively with the same schema. Arterial tension through an invasive approach is measured during the test.
Analysis of inflammation and cellular adhesion markers and free radicals
