How to measure quantitative blood loss

Weigh all blood-soaked materials and clots. Calculate the weight and convert to milliliters. At the end of the surgery, add the volume of quantified blood calculated by weight with the volume of quantified blood in the suction canister to determine total quantification of blood loss.

What is the best way to ascertain blood loss?

A more precise measurement of blood loss is haemoglobin concentration (Hb) in venous blood sampling and spectrophotometry. With the dye dilution technique, a known quantity of dye is injected into the vein and its plasmatic concentration is monitored after the uterus stops bleeding.

Why is QBL better than EBL?

QBL also outperformed EBL for predicting transfusion after vaginal delivery (AUC 0.93 vs 0.81, P=0.03). QBL is a more sensitive test for detecting clinically significant blood loss, which could lead to earlier recognition of hemorrhage and interventions.

What is quantitative blood?

A quantitative human chorionic gonadotropin (HCG) test measures the specific level of HCG in the blood. HCG is a hormone produced in the body during pregnancy. Other HCG tests include: HCG urine test. HCG blood test -- qualitative.
