Platelets play a central part not just in homeostasis and thrombosis as the primary effector cells, but they are also key cells in the regulation of the immunological response to various stressors. After activation, platelets release their granules which store different inflammatory mediators that induce coagulation, recruit further platelets, activate complement, attract neutrophils and leukocytes and regulate the vascular tone. Platelets activated by systemic inflammation and infection, may also contribute to the development of multiple organ failure. Thus, inhibition of platelet activation may have beneficial effects on critically ill patients.
the investigators hypothesize that acetylsalicylic acid reduces the mortality of medical intensive care unit patients. In a retrospective study acetylsalicylic acid use was associated with a substantial reduction in a medical intensive care unit population (Winning et al., 2010).
The investigators will conduct a randomized, double-blind study including 460 patients (2x230), who will be randomized to receive 100mg acetylsalicylic acid(daily, intravenous) or a placebo (0,9% sodium-choride solution) to assess whether acetylsalicylic acid reduces the mortality of medical intensive care unit patients.
Main outcome criteria will be 28/90day-mortality. Furthermore the investigators will assess whether acetylsalicylic acid reduces the risk of suffering thromboembolic complications.
Post-mortem examinations will be conducted in all patients who die in the course of the study.
Furthermore we will assess bleeding rates, intensive care unit mortality and pharmacokinetic and pharmacodynamic properties of acetylsalicylic acid in the intensive care unit population.

- 28-/90-day mortality [ Time Frame: 28-/90-days ]Standard outcome measure of investigational intensive care unit trials.
- intensive care unit mortality [ Time Frame: up to 90 days after inclusion ]Mortality of patients during their intensive care unit stay, 90 day mortality, potentially longer

- Incidence of thromboembolic events [ Time Frame: average 28 days ]clinically relevant thromboembolic events assessed by standard care, potentially longer
- post-mortem-examinations [ Time Frame: average 28 days ]post mortem examinations will be carried out in all patients who die during their intensive care unit stay. specific interest will be paid to thromboembolic events, potentially longer
