>> Narrator: Every year in the US, patients receive

21 million blood transfusions.

What if there was a better solution, with significantly

improved outcomes?

>> So nearly every surgical procedure involves some degree

of blood loss and traditionally, we give patients blood

from the blood bank.

However, another option exists, which is called Bloodless

Medicine and Surgery, where we use alternative

to transfusion.

>> Narrator: Techniques performed before, during and after

surgery result in minimized blood loss, faster recovery,

fewer infections and quicker discharge.

Bloodless medicine eliminates the need for

a blood transfusion, thus avoiding the dangers

of allergic reaction, contamination and the possibility

of receiving the wrong blood type.

Before surgery, medication and nutritional supplements

increase hemoglobin levels, which help your body handle

blood loos during surgery.

A process called Hemodilution temporarily replaces

a portion of the patient's blood with fluids, lessening

the impact of blood loss during surgery.

Tools and techniques during surgery include anesthesia

processes to safely lower blood pressure, harmonic scalpels

clot the blood while cutting the tissue.

Cell salvage machines collect lost blood, wash it

and return it to the patient.

Hemoglobin monitors reduce the need to collect blood samples

to be sent to the lab.

After surgery, medications and techniques can minimize

bleeding and improve oxygen in the blood.

Often after surgery, blood must be drawn to run follow up

testing in the lab.

Microsampling requires 1/10th the amount of blood

traditionally drawn, reducing the amount of blood

patients lose by almost 90%.

At Johns Hopkins, our team of highly trained experts

have been providing patients alternatives and peace

of mind for years.
