Embodiment 1

[0032] Example 1: Patient A, male, aged 35 years, needs to predict the amount of plasma replacement

[0033] 1) Weigh the body weight of patient A, its body weight is 66 kilograms; Detect the initial bilirubin concentration Dhs of patient A, obtain its initial bilirubin concentration Dhs to be 25.12; Detect the hematocrit Hct of patient A, obtain its red blood cell Compaction Hct=37.7; then input the results of weighing and testing into the computer;

[0034] 2) Utilize the program stored in the computer first, according to the following formula Vol=(1-Hct)×(b+c×Weight), wherein b=1530, c=41, calculate the individual plasma volume of patient A Vol= 2639.028ml;

[0035] 3) Then use the program stored in the computer to calculate the maximum estimated value, theoretical estimated value and minimum estimated value of the plasma dosage according to the following three plasma dosage calculation formulas respectively,

[0036] maximum estimate Result ...

Embodiment 2

[0047] Example 2: Patient B, male, aged 17, needs to predict the amount of plasma replacement

[0048] 1) Weigh the weight of patient B, whose body weight is 60.5 kilograms; detect the initial bilirubin concentration Dhs of patient B, and obtain its initial bilirubin concentration Dhs to be 21.43; detect the hematocrit Hct of patient B, obtain its red blood cell Compaction Hct=44.8; then input the weighing and testing results into the computer;

[0049] 2) First utilize the program stored in the computer, according to the following formula Vol=(1-Hct)×(b+c×Weight), wherein b=1530, c=41, calculate the individual plasma volume of patient B Vol=2213.796ml;

[0050] 3) Then utilize the program stored in the computer to dig out the three plasma dosage calculation formulas of the present invention respectively, wherein the value of the expected bilirubin concentration ExpDHS is 10.00, and the value of the plasma replacement speed Velocity is 30, calculate The result is as follows:...

Embodiment 3

[0054] Example 3: Patient C, female, aged 47 years, needs to predict the amount of plasma replacement

[0055] 1) Weigh the weight of patient C, whose body weight is 63 kilograms; detect the initial bilirubin concentration Dhs of patient C, and obtain its initial bilirubin concentration Dhs to be 25.7; detect the hematocrit Hct of patient C, obtain its red blood cell Compaction Hct=38.5, then input the results of weighing and testing into the computer;

[0056] 2) Utilize the program stored in the computer, according to the following formula Vol=(1-Hct)×(b+c×Weight), wherein b=864, c=47.2, calculate the individual plasma volume Vol of patient C =2360.12ml;

[0057] 3) Then, using the program stored in the computer, respectively according to the three plasma dosage calculation formulas of the present invention, wherein the value of the expected bilirubin concentration ExpDHS is 11.30, and the value of the plasma replacement velocity Velocity is 30, the calculation is obtained ...

Abstract

The invention relates to a blood plasma replacement dosage forecasting method, for solving the problems that the existing forecast is inaccurate and the blood plasma resources are wasted. The method includes the steps of: 1) weighing a patient and detecting his initial bilirubinen concentration and Hct. of red blood cells and inputting the weighing and detection results into a computer; 2) by computer program, calculating his individual blood plasma quantity according to a formula; 3) calculating the maximum, theoretical and minimum estimated values of blood plasma dosage according to a formula based on a blood plasma replacement model.

Description

technical field [0001] The invention relates to a method for predicting the dosage of plasma replacement, which assists doctors to formulate a reasonable dosage of plasma when using the plasma replacement system clinically, saves limited resources and obtains the greatest social benefits. Background technique [0002] Plasma exchange (PE) is a commonly used clinical blood purification technology, which has developed rapidly in recent years. At present, plasma exchange is widely used in the treatment of severe liver disease, autoimmune disease and drug toxicity. The basic principle is: take the patient's blood out of the body, separate the plasma and blood cells through a special device, discard the plasma containing pathogenic factors or toxins, and replace the separated blood cells with fresh frozen plasma and other replacement fluids. Infuse back into the body to achieve the purpose of removing pathogenic factors in plasma and treating diseases. [0003] However, there a...
