Effect of acute normovolemic hemodilution on distribution of blood flow and tissue oxygenation in dog skeletal muscle.
Acute normovolemic hemodilution (ANH) is efficient in reducing allogenic blood transfusion needs during elective surgery. Tissue oxygenation is maintained by increased cardiac output and oxygen extraction and, presumably, a more homogeneous tissue perfusion. The aim of this study was to investigate blood flow distribution and oxygenation of skeletal muscle. ANH from hematocrit of 36 +/- 3 to 20...
متن کاملAcute normovolemic hemodilution improves oxygenation in ischemic flap tissue.
BACKGROUND The flaps used in reconstructive surgery are prone to ischemia and hypoxia, which imply a considerable risk of wound-healing complications. During normovolemic hemodilution, the oxygenation may further deteriorate because of the lack of erythrocytes or improve because of increased microcirculatory blood flow. The aim of this study was to investigate the net effect of normovolemic hem...
متن کاملMyocardial Oxygenation during Acute Normovolemic Hemodilution: Impact of Hypocapnic Alkalosis.
BACKGROUND Increases in myocardial blood flow preserve myocardial oxygenation during moderate acute normovolemic hemodilution. Hypocapnic alkalosis (HA) is known to cause coronary vasoconstriction and increase hemoglobin-oxygen affinity. We evaluated whether these effects would compromise myocardial oxygenation during hemodilution. METHODS Eighteen anesthetized dogs were studied. Myocardial b...

15 صفحه اولEffect of hemodilution on the distribution of renal blood flow.
We evaluated the effects of hemodilution, expansion of intravascular volume, and expansion of interstitial volume on the distribution of cortical renal blood flow, utilizing the microsphere technique. Hemodilution without volume expansion (saline exchange) produced an increase in fractional blood flow in zone 1 (outermost zone) of the cortex from 34 plus or minus 1% to 43 plus or minus 2% and a...
