2017-11-25 Hemodilution induces macro- and microcirculatory responses, allowing the adaptation of the organism to the dilution-associated reduction in the oxygen content of the blood. While the cardiovascular response consists mainly of an increase in cardiac output and organ blood flow – normovolemia provided – the microcirculation responds with an increase of red blood cell velocity, more Blood volume analysis can distinguish true anemia from hemodilution in critically ill patients J Trauma. 2011 Mar;70(3):646-51. doi: 10.1097/TA.0b013e31820d5f48. Authors Philbert Y Van 1 , Gordon M Riha, S David Cho, Samantha J Underwood, Gregory J Hamilton, Ross Anderson, L Bruce Ham, Martin A Schreiber. Affiliation 1 Division of Experimental and clinical studies demonstrate that oxygen transport is maximized at hematocrit values ranging from 30% to 35%.

10)Hemodilution and Kidneys - Acute renal failure or a significant increase in postoperative serum creatinine increases as hematocrit values decreases below 21%–24% on CPB. HCT <24% on CPB is the “critical threshold” triggering significantly worsened renal outcomes. 11)Hemodilution and CNS - hemodilution.

Blood samples for evaluation of hemostasis were collected at moments M1 before hemodilution, M2 20 minutes after obtaining a hematocrit of 30%, and M3 20 minutes after obtaining a hematocrit of 20%. Before hemodilution, blood samples were collected to perform hemodilution in a test tube. Normal Laboratory Values for Examinations . LABS METRIC VALUES S.I. UNIT VALUES.

In the ﬁrst few days postinjury or postoperatively, a decrease in the hemat-ocrit level is commonly observed, which is often attributed to hemodilution rather than a loss of red cell mass. However, Mean differences between pHct and nHct in each group were 4.5% ± 3.1% (p≤0.01), 0.0% ± 1.2% (p=0.85), and -6.5% ± 4.1% (p≤0.01), respectively. pHct, when compared with nHct, diagnosed anemia (Hct <30) nearly equal within the hypovolemic and normovolemic groups. A prolonged partial thromboplastin time (PTT) indicates the need to perform specific coagulation factor assays.

MABL is the maximal blood loss that can be tolerated without any additional blood products. The variable with the smallest MABL thus limits hemodilution Hemodilution Causes Hemodilution in the thinning of blood. Which may be occur due to many factors, some of them are as follows; Hemodilution normally occurs during pregnancy, but it can also occur in non-pregnant women due to less concentration of hemoglobin. It may be occur due to chronic heart failure as poor blood output is reported. 2003-07-23 Values are slightly lower in older adults.Reference range values may vary between and hemodilution. Causes of blood loss include menstrual excess or frequency, gastrointestinal bleeding, inflammatory bowel disease, and hematuria. Decreased blood cell production can be caused Davis's Lab & Diagnostic Tests, 7th ed., F.A. Davis Company hemodilution group.

Thus during pregnancy, anemia is defined as hemoglobin (Hb) < 10 g/dL (Hct < 30%). If Hb is < 11.5 g/dL at the onset of pregnancy, women may be treated prophylactically because subsequent hemodilution usually reduces Hb to < 10 g/dL. Despite hemodilution, oxygen-carrying capacity remains normal throughout pregnancy. PTCA: HemoTec > 275 to 300 seconds, or Hemochron > 340 to 400 seconds. CABG: The accepted goal for the ACT is 400-480 seconds. Vascular catheterization, hemodialysis, or extracorporeal membrane oxygenation (ECMO): determine the heparin dose from a standard nomogram adjusted for the patient's baseline ACT.
