Calculating inflammatory indices
In the pre-operative phase, it is useful to assess the patient's level of inflammation.
There are several indices calculated from the blood count, which can be predictive of events that may occur postoperatively.
The blood count elements to be taken into account are :
- Neutrophils
- Lymphocytes
- Monocytes
- Platelets
SII: Systemic Immune Inflammation Index 380 - 500
Neutrophils x Platelets
Lymphocytes
SIRI: Systemic Immune Response Index 0,5 - 1,3
Neutrophils x Monocytes
Lymphocytes
Platelets :
A level above 300,000 is a warning signal to calculate the indexes.
