Blood transfusion is an important treatment method in clinical medicine, which is of great significance for rescuing critically ill patients and surgery. However, there are some risks in blood transfusion, such as excessive blood transfusion and transfusion reaction, so the calculation and evaluation before blood transfusion is very important. Let's introduce the formula table of blood transfusion formula to help you better understand and apply blood transfusion therapy.
Before blood transfusion, it is necessary to calculate the amount of blood transfusion according to the patient's hemoglobin concentration and bleeding. The following is a common formula table for calculating blood transfusion formula:
Blood loss (ml)=[ hemoglobin concentration (g/dl)× body weight (kg)× bleeding time (minutes) ]/3000.
Erythrocyte requirement U= body weight (kg)×[ 100ml/kg× bleeding volume (ml)]/ hematocrit plasma requirement (ml).
Red blood cell requirement U= body weight (kg)×[0.2× bleeding volume (ml)] platelet requirement (u).
Erythrocyte requirement U= body weight (kg)×[0.2× bleeding volume (ml)]/ 100000 cold precipitation requirement (u).
Red blood cell requirement U= weight (kg)×[0.2× blood loss (ml)]/20000.
In the above formula, the unit of bleeding time is minutes, the unit of hematocrit is%, and the unit of weight is kilograms. According to the patient's specific situation, the required blood transfusion can be obtained by selecting the appropriate blood transfusion formula for calculation.
Blood transfusion is an important treatment, but not all patients need blood transfusion. Blood transfusion indications include hemorrhagic shock, severe anemia, myocardial infarction, surgery and so on. When deciding whether to carry out blood transfusion, it is necessary to evaluate and judge according to the specific situation of the patient.
According to different treatment needs, blood transfusion can be divided into whole blood transfusion, component transfusion and autologous transfusion. Whole blood transfusion refers to inputting whole blood into patients; Component blood transfusion refers to extracting a component from blood and then inputting it into the patient; Autologous blood transfusion refers to the collection of patients' own blood, which is processed and input into patients' bodies.
Although blood transfusion is an important treatment, it also has certain risks and adverse reactions. Common adverse reactions of blood transfusion include allergic reaction, hemolytic reaction and fever reaction. In the process of blood transfusion, we should observe the patient's reaction and find and deal with the adverse reactions in time.
In order to ensure the safety and effectiveness of blood transfusion, the hospital needs to establish a perfect blood transfusion management system and process. Including screening of blood donors, storage and transportation of blood, evaluation and calculation before blood transfusion, monitoring and management during blood transfusion, etc. At the same time, it is necessary to train and manage blood transfusion related personnel to ensure the safety and effectiveness of blood transfusion.
In a word, the formula table of blood transfusion formula is an important tool in clinical medicine, which can help doctors accurately judge the amount and type of blood transfusion. At the same time, it is of great significance to know the indications, types, adverse reactions and treatment of blood transfusion for better application of blood transfusion treatment.
