Gentile et al identified risk factors associated with thrombosis of a subclavian central venous catheter placed in a trauma patient. These can help to identify a patient who should be monitored more closely. The authors are from the University of Bordeaux and multiple hospitals in France.
Patient selection: trauma patient with a subclavian central venous catheter
Parameters:
(1) age in years
(2) intracranial hypertension (ICHT)
(3) blood transfusion
(4) position of the catheter tip
(5) ipsilateral jugular catheter
(6) use of low molecular weight heparin

where:
• The catheter tip in the internal jugular or innominate vein is considered misplaced.
total number of risk factors =
= SUM(points for all 6 parameters)
Interpretation:
• minimum number of risk factors: 0
• maximum number of risk factors: 6
• The risk of thrombosis increases with the number of risk factors.
