Increase in the fluid content of blood, resulting in diminution of the concentration of formed elements.
see Triple H therapy.
Hemodilution is used to lower hematocrit.
Consider for Emergency carotid endarterectomy with acute neuro deficit.
High hemoglobin (HGB) level was associated with increased risk of postsurgical cerebral ischemia, pulmonary embolism and lower-limb DVT and poor prognosis in poor grade aneurysmal subarachnoid hemorrhage patients. Preoperative hemodilution therapy might be beneficial in reducing operative complications, reducing hospital stay and improving short-term prognosis for neurological functional recovery in aSAH patients with high hemoglobin concentration, but further detailed research is needed 1).
