Recruitment and inclusion criteria
- 15 mechanically ventilated critically ill patients fulfilling criteria of SIRS (2 symptoms: RR > 20/min, HR > 90/min, Temp. > 38°/< 36°, 12G/l< WBC < 4G/l; assumed or proven infection, persistent hypotension refractory to fluid therapy and need for vasopressors.
- Time window for inclusion: up to 72h after onset of symptoms
Exclusion criteria
- PLT < 50G/l,
- PT < 50%,
- Continuous therapeutic anticoagulation,
- DIC, st. p. MCI within 14 days,
- Gastrointestinal perforation,
- Age < 18 years,
- Age > 80 Years
SIRS:
Recruitment and inclusion criteria
- 15 mechanically ventilated critically ill patients fulfilling criteria of SIRS (2 symptoms: RR > 20/min, HR > 90/min, Temp. > 38°/< 36°, 12G/l < WBC < 4G/l; assumed or proven infection
- Time window for inclusion: up to 72h after onset of symptoms
Exclusion criteria:

Andet: Septic Shock
Activity of the brush border membrane enzymes intestinal alkaline phosphatase, maltase and lactase, as well as brush border morphology determined from duodenal biopsies in patients with septic shock
|
When gastroscopy is indicated for clinical reasons, duodenal biopsies to determine the activity of the brush border membrane enzymes intestinal alkaline phosphatase, maltase and lactase, as well as assessing brush border morphology are taken
|
