What is preoperative anemia?






We all know what anemia is, so do you know what preoperative anemia is?

In this article, let us take a detailed look at the concept of preoperative anemia.


Preoperative assessment and treatment of anemia is a data that must be considered in perioperative risk stratification.

However, at present, it is still very difficult to apply preoperative anemia treatment to clinical practice. Moreover, there is little evidence that the treatment of preoperative anemia can actually improve patient outcomes.


Data show that 20% to 40% of adult patients undergoing cardiac surgery have preoperative anemia.

Common intraoperative risk factors in patients with preoperative anemia include:

Advanced age, cardiovascular disease, renal insufficiency, diabetes, low BMI, etc.


Our last article explained the relationship between preoperative anemia and perioperative prognosis, which can be viewed if necessary.



Here we introduce a new approach, "Patient Blood Management (PBM)."

PBM is a method based on evidence-based medicine and a combination of multiple disciplines. 

By preventing and treating anemia, improving coagulation function, and minimizing intraoperative blood loss, thereby reducing or avoiding allogeneic blood transfusion, patients have better clinical outcomes.



The current findings suggest that preoperative anemia leads to more severe postoperative anemia. This requires us to pay attention to the assessment and prevention of preoperative anemia. 

During the perioperative period, it is recommended to always pay attention to the vital signs of the patient's body. Blood oxygen, blood pressure, and body temperature are all extremely important factors. It is recommended to use a medical temperature probe to monitor the patient's body temperature in real time, and it is recommended to use a blood oxygen probe to pay attention to the patient's blood oxygen level in real time, so as to make the perioperative period better.
