Acute bleeding[edit | edit source]

  • there is "oligemia" (reduction in blood volume) - a sudden loss of approx. 1/3 of the blood volume (i.e. approx. 1.5-2 l in an adult) leads to circulatory failure,
  • Clinically, blood loss is manifested by tachycardia, a decrease in blood pressure, a threadlike pulse, cold extremities and shortness of breath (due to insufficient transport capacity for oxygen). After replenishing the intravascular volume, typical signs of anemia (fatigue, shortness of breath, pallor, tachycardia) may appear.
  • In the blood count, the bleeding becomes apparent only after a few hours, when the missing intravascular fluid volume is moved from the interstitium. Anemia then has a normochromic normocytic picture. Over time, there will be an increase in the number of reticulocytes.
  • Therapy: stop the bleeding, the missing blood volume is replenished depending on the amount of blood loss with blood plasma substitutes (colloid solutions), plasma or whole blood.
