Diagnostic criteria for post-pericardiotomy syndrome?
2 of the following:
Pleuritic CP, friction rub, pleural effusion, new or worsening pericardial effusion, fever > 1wk postop
Definition of myopericarditis
Elevation of cardiac enzymes or new LV dysfxn
What population is prone to get myopericarditis?
definition of pulsus paradoxus (Tamponade)
inspiratory decrease in SBP >10
what causes false positive results for pulsus paradoxus, making you think there is tamponade?
COPD, PE, constriction
what causes false negatives for pulsus paradoxus?
LVH, AI, ASD, vent, localized effusion, severe hypotension
Rx of tamponade
IVF, inotropes/vasopressors if hypotension persists, pericardiocentesis, avoid vent
