Blood removal before major liver surgery cuts transfusions in half, clinical trial shows

Removing 10% of a patient's blood before major liver surgery and giving it back afterwards reduced transfusions by half, according to a large clinical trial. Known as hypovolemic phlebotomy, this practice could save one in every 11 patients having this surgery from needing a transfusion.
"Blood loss is a major concern in liver surgery. Taking out half a liter of blood right before major liver surgery is the best thing we've found so far for reducing blood loss and transfusions," said Dr. Guillaume Martel.
"It works by lowering the blood pressure in the liver. It's safe, simple, inexpensive, and should be considered for any liver surgery with a high risk of bleeding."
In the largest trial of its kind, 446 people having major liver surgery were recruited at four Canadian hospitals between 2018 and 2023.
Once under anesthetic, patients were randomly assigned to receive either hypovolemic phlebotomy or usual care. Only the anesthesiologist knew which patients were in which group.
For patients in the hypovolemic phlebotomy group, the anesthesiologist removed the equivalent of one blood donation (about 450 mL) into a blood bag before surgery. If the patient needed blood during surgery, their blood was used first. Otherwise, it was re-infused before they woke up.
According to hospital blood bank data and patient medical records, 7.6% of those who received hypovolemic phlebotomy (17 of 223) had blood transfusions in the 30 days after surgery compared to 16.1% (36 of 223) of those who received usual care. Hypovolemic phlebotomy caused no more complications than usual care.
Surgeons also said hypovolemic phlebotomy made the surgery easier to do, because there was less blood obscuring the places they needed to cut. Median estimated blood loss was 670 mL with hypovolemic phlebotomy compared to 800 mL with usual care.

Thank you very much and God bless you.
I would much prefer to get my own blood back, than to get someone else’s.
For voluntary surgeries, this could be something we could request; however, this was only for liver surgery.
