Gestational (incidental) thrombocytopenia is a condition that commonly affects pregnant women.Thrombocytopenia is defined as the drop in platelet count from the normal range of 150,000–400,000/μL to a count lower than 150,000/μL. [1]
In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
A normal human platelet count ranges from 150,000 to 450,000 platelets/microliter (μL) of blood. [4] Values outside this range do not necessarily indicate disease. One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5]
Neonatal alloimmune thrombocytopenia (NAITP, NAIT, NATP or NAT) is a disease that affects babies in which the platelet count is decreased because the mother's immune system attacks her fetus' or newborn's platelets. A low platelet count increases the risk of bleeding in the fetus and newborn.
The use of cytochalasin is more favorable than using glycoprotein IIb/ IIIa inhibitors which block platelet incompletely, especially at higher platelet counts. [18] FIBTEM allows for the detection of fibrinogen deficiency or fibrin polymerization disorders, e.g. induced by certain plasma expanders, and may identify rapidly the need to ...
Higher platelet transfusion thresholds have been used in premature neonates, but this has been based on limited evidence. [19] There is now evidence that using a high platelet count threshold (50 x 10 9 /L) increases the risk of death or bleeding compared to a lower platelet count threshold (25 x 10 9 /L) in premature neonates. [20]
In this article, all values (except the ones listed below) denote blood plasma concentration, which is approximately 60–100% larger than the actual blood concentration if the amount inside red blood cells (RBCs) is negligible.
leukopenia: total white cell count < 4.0 x 10 9 /L. Decrease in all types of white blood cells (revealed by doing a differential count). thrombocytopenia : platelet count < 150×10 9 /L. Treatment
