21. A positive result is indicative of intravascular haemolysis. 22. These intravascular merozoites infect variable numbers of erythrocytes. 23. Rarely more severe symptoms occur including hemolysis, thrombocytopenia, and disseminated intravascular coagulation. 24. Now doctors will be able to use the new devices, called intravascular brachytherapy systems. 25. Among them is disseminated intravascular coagulation, or DIC _ where the body consumes platelets. 26. Therefore, haptoglobin is not a reliable way to differentiate between intravascular and extravascular hemolysis. 27. Symptoms are high fevers and purple skin patches ( purpura due to disseminated intravascular coagulation ). 28. If given intravenously, isotonic crystalloid fluids will be distributed to the intravascular and interstitial spaces. 29. PFCs in solution act as an intravascular oxygen carrier to temporarily augment oxygen delivery to tissues. 30. The distinguishing feature of intravascular hemolysis is the release of RBC contents into the blood stream.
