Brief Summary
Pilot data in patients and data from pig studies indicate that arginine-NO metabolism is impaired in sepsis with changes in splanchnic metabolism and function, and reduced survival at low nitrate levels. Prolonged intravenous supplementation of L-arginine proved effective in pigs for increasing NO production, restoring gut function, and inhibiting an increase in pulmonary arterial pressure, without any deleterious systemic side effects. Prolonged intravenous L-arginine supplementation could therefore be useful in septic ICU patients.

Eligibility Criteria
You may qualify if:
- Written informed consent from close relative
- Age \> 18 years
- Patient must be relatively hemodynamically stable, defined as stable blood pressure (variation in mean arterial pressure \<15 mm Hg) during 2 h without necessity of increasing the vasopressor dose, inotropic support or rate of fluid administration.
- Systemic and pulmonary arterial catheters in place with continuous pressure monitoring.
- Patients in whom the clinician is prepared to provide full life support during the duration of the study, including a life expectance of \> 24 h.
You may not qualify if:
- Shock due to any cause other than sepsis (e.g. drug reaction or drug overdose, pulmonary embolus, burn injury etc.)
- Corticosteroid use (prolonged intake of \> 1mg/kg daily or intake of \> 70 mg/day for 7 consecutive days within 1 month preceding the study)
- Liver cirrhosis
- Chronic pancreatitis
- Diabetes mellitus type I
- Metastases, haematological malignancies or chemotherapy
- Patients on dialysis (CVVH or other)
