[HSF]diagnosis of tamponade

[Donald Ross]

Okay,
You left a tube in the pericardium during surgery to enable   
tamponade diagnosis???
Not something that would be a practical for routine surgery.
I also surmise that your catheter may not necessarily give a  
representative reading if clots partitioned the pericardial cavity.
The diagnosis of post-op tamponade is notoriously elusive.
Does anyone believe there is a gold standard test?
