Abstract

Objective:

Through researching preoperative coagulation function in the case of ABO-identical blood insufficient for emergency rescue transfusion according to recommended programs of special emergency rescue transfusion was carried out, the relationship between volume of blood products and coagulation function was analyzed.

Methods:

The surgical cases of blood transfusion more than 1 600 ml during operation were collected in our hospitals from Aug 2015 to Dec 2016（n=218）, these cases were divided into the normal coagulation group（Group A） and abnormal coagulation group（Group B）, and the patients of emergency rescue transfusion O type blood group（Group C）. The basic information of cases, the infused volume of red blood cell（RBC）, virus-inactivated frozen plasma（VIFP）, fresh frozen plasma（FFP）, cryoprecipitate（C）and platelets（P）, prothrombin time（PT）, activated partial thromboplastin time（APTT）, fibrinogen（FIB）and international normalized ratio（INR）were analyzed, the relationship between volume of blood transfusion and coagulation function were also analysed. At the same time, the efficiency and safety index were compared before and after transfusion. These indexes, such as hemoglobin（Hb）, indirect bilirubin（IBiL）, direct antiglobulin test（DAT）and irregular antibody were determined at the time-paints of 24 h, 3 d and 7 d after blood transfusion.

Results:

The differences of age and blood type between group A and B was not statistically significant（P>0.05）. Proportion of A and AB type，transfusion volume of RBC, FFP, C and Plt all were significantly higher in group C （P<0.05）. PT, APTT, FIB and INR in group B and C were significantly different（P<0.05）, which related with the transfusion volume of RBC, FFP and C（P<0.05）. DAT and irregular antibody in every group was all negative before transfusion, No any new irregular antibodies had been detected after transfusion. Hb after blood transfusion was not statistically different before and after transfusion in group C, the IBiL level also was not significantly increased after blood transfusion（P > 0.05）. All those showed that emergency rescue transfusion was safe and effective.

Conclusion:

Preoperative coagulation function is one of factors inflnencing blood products transfusion volume during operation, which also is the basis for evaluating bleeding and blood transfusion. Emergency O type blood and ABO-matched blood transfusions show the same efficiency and safety.

Blood Transfusion

Blood Transfusion

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Blood Transfusion and Agglutination

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Coagulation

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Coagulation

Coagulation

The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Emerging Adulthood

Emerging Adulthood

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...
