Systemic inflammatory response syndrome ( SIRS - English systemic inflammatory response syndrome ) is the medical term for a systemic inflammatory reaction of the organism , in which it takes place throughout the body, regardless of where it was triggered, while a local inflammatory reaction to a specific one Body region remains limited.
Diagnosis
At least two of the following criteria must be met in order to be able to diagnose SIRS:
- Body temperature ≥ 38 ° C (increased body temperature above subfebrile temperatures) or ≤ 36 ° C
- Heart rate ≥ 90 / min ( tachycardia )
- Tachypnea : respiratory rate ≥ 20 / min or hyperventilation with p CO 2 ≤ 32 mmHg
- Leukocytosis (≥ 12000 / μl) or leukopenia (≤ 4000 / μl) or shift to the left (i.e.> 10% immature granulocytes in the differential blood count ).
The combination of fever + leukocytosis is the more common one and suggests an adequate to excessive reaction of the immune system, while the combination of body temperature <36 ° C + leukopenia , also known as cold SIRS , is less common and usually occurs in the case of immune deficiency .
If the SIRS is caused by an infection , it is called sepsis .
causes
Causes of SIRS can be: immunological , chemical reasons (e.g. acute pancreatitis ), shock , burns , major operations (especially operations with extracorporeal circulation such as large heart operations or large wound areas), severe trauma or various serious illnesses (e.g. necrotizing pancreatitis ).
