Platelet transfusion guidelines
Platelet count–PC < 20 x 109/L–US: < 20 000/mm3
PC < 40 x 109/L in active hemorrhage
PC < 50 x 109/L in neonates, or Pts with documented coagulopathies, recurrent fever, severe infections or receiving drugs that cause platelet dysfunction
PC < 100 x 109/L before 'bloody' surgery, eg cardiopulmonary bypass or < 48 hrs after surgery
Bleeding time > twice upper limit of normal
For transfusing one unit of random-donor platelets/10 kg body weight/24 hrs
