What Is Known And Objective:
Prothrombin complex concentrate (PCC) is a plasma-derived concentrate used to replenish clotting factors. There are limited recommendations for treating coagulopathy induced by direct oral anticoagulants (DOAC). Data are limited regarding both total dose and repeated dosing with this population.
Case Summary:
We describe a case of an adult patient anticoagulated with apixaban who received two 35 unit/kg doses of PCC resulting in suspected pulmonary embolism.
What Is New And Conclusion:
Treatment of DOAC-induced bleeding remains an "off-label" indication for PCC. Additional doses should be given with caution if given at all and patients monitored closely.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
