When should you look for autogenous blood regression?

Contraindication for autologous blood reflux:

1. Sepsis and blood contamination. The presence or absence of gastrointestinal tract injury, especially colon injury, should be prohibited during surgery;

2. Patients with malignant tumor may have cancer cells mixed in their blood, so it is generally forbidden to return;

3. Recovery of blood beyond the specified time. Such as open trauma (more than 4 hours) and severe heart, liver, and kidney function.

Autogenous blood:

The negative pressure suction should not be too high, generally no more than 6.5kPa, to reduce the damage to red blood cells. When returning blood, changes in blood pressure, pulse, temperature and urine volume should be closely observed. Stop immediately when blood pressure changes, fever, chills, etc. Hb, HCT, RBC, PLT, MAP, HR, PT, APTT and FBG were detected in time 1 day and 1 week after transfusion. Sterility should be emphasized when returning blood to prevent contamination.

2. In order to prevent and reduce complications, 1000mL of blood was returned each time during and after the operation, and 1g of normal calcium supplement and 60-80ml of sodium bicarbonate were added. After hemoglobinuria, add 5% sodium bicarbonate. Clear urine and use 20 mg of furosemide to protect kidney function. In principle, the time from injury to autologous blood transfusion is within 24 hours. According to reports in the literature, autotransfusion has no obvious adverse reactions for 26 to 44 hours, but it should be paid attention to for more than 48 hours. It should not be used if the blood is dark red and opaque, or if there are penetrating wounds, open wounds, and those with chills.
