Management of Hematologic Abnormalities in Patients with Cyanotic CHD
摘要
Chronic exposure to low oxygen saturation in patients with cyanotic CHD is generally adapted physiologically by an increase of red blood cell mass to improve oxygen delivery; this process is called secondary erythrocytosis. Pathological consequences of secondary erythropoiesis, such as polycythemia, iron deficiency, coagulopathy, and hyperuricemia, are undesirable and should be prevented as much as possible.
