Determination of red blood cell destruction site

Mature red blood cells have a life span of about 90 to 120 days after being released into the blood. About 8% of aging red blood cells per day in adults are mainly destroyed in the spleen and decomposed into iron, globin and bilirubin. People who need to be examined have people who have difficulty breathing, palpitations, shortness of breath, anemia, infection, and bleeding. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: After 8 pm on the day before the medical examination, you should start fasting for 12 hours, so as not to affect the test results. Normal value 51Cr labeled red blood cell method Liver (L) / heart (P) 0.60 ~ 1.08. Spleen (S) / heart (P) 0.80 ~ 1.35. The spleen destruction index S/P < 1.5. The liver excess index L/P<1.0; S/L is 0.9-1.8. Clinical significance Abnormal results: (1) S/P>1.5 spleen is the site of destruction of red blood cells, and is indicated for spleen resection. (2) S/P<1.5 spleen does not destroy the red blood cell site, and the spleen is a non-resection indication. (3) S/P starts to be high and constant, and there is no persistent increase in splenomegaly but no hypersplenism. (4) S/P begins to increase, and continues to increase spleen function. (5) S/P increased significantly and continued to rise, rapidly >2 hemolytic anemia. People who need to be examined have people who have difficulty breathing, palpitations, shortness of breath, anemia, infection, and bleeding. Precautions Before inspection: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. After inspection: 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process The examination process: blood is drawn, blood is taken for examination, and venous blood is generally taken, and blood is drawn by a doctor or a nurse. The amount of blood drawn is determined according to the difference of the test content and the number of items. The blood volume is usually 2-20 ml, and the maximum is not more than 50 ml. Then check by a doctor. Not suitable for the crowd Hemophilia and diffuse intravascular coagulation. Adverse reactions and risks Dizziness or fainting: When blood is drawn, due to emotional overstress, fear, reflex caused by vagus nerve excitability, blood pressure drop, etc., the blood supply to the brain is insufficient to cause fainting or dizziness.
