Bloodless Heart Surgery.
A professional journey toward better surgical care.
My interest in developing bloodless heart surgery techniques bloomed early in my professional career. I have always been interested in offering my patients the best low-impact, minimally invasive heart surgery available for their heart disease. The adoption of no blood heart surgery techniques is an important aspect of my care. I started to employ these techniques in the late 90's to comply with the religious beliefs of the Jehovah's Witness congregations first in Pittsburgh and in New York City and now in my specialized referral center in Ohio.
I currently see a growing number of patients from out of state who specifically travel to my center to undergo bloodless heart surgery procedures that were not otherwise available in their town or state. First, let me spend a few words for those of you who are not familiar with the beliefs of the Jehovah's Witness community about blood transfusions. Witnesses embrace and are comfortable with all aspects of modern medicine but their refusal to receive a blood transfusion is not negotiable. Sometimes a finer distinction is made between refusing Packed Red Blood Cells and accepting some of the other blood fractions (i.e.: Fresh Frozen Plasma, Platelets, Cryoprecipitate) on an individual basis. The aversion to receive blood transfusions stems from the interpretation of a specific passage in the Bible that states "Thou shalt not eat blood" and the spiritual ramifications of the disregard of this rule. I have treated hundreds of observant Jehovah's witnesses who would rather die or suffer untoward consequences than break their religious rules. As a treating physician and a fellow human being I have learned to respect their strong faith while offering a safe treatment of their heart disease. Over the years I have developed very effective clinical strategies and routines that have made bloodless heart surgery a reality for most of my patients. Bloodless heart surgery care is an increasingly popular choice for all patients that need surgery in a growing number of medical institutions. It is interesting to note that more and more patients are becoming interested in bloodless heart surgery, regardless of their religious beliefs. It turns out that avoiding the transfusion of blood products has significant clinical benefits related to:
- A careful preparation of each patient for bloodless heart surgery
- A precise and meticulous technique during surgery
- A thourough postoperative follow-up
- The avoidance of potential side effects and complications related to blood transfusions
In the late 90's a sizeable number of patients were not choosing bloodless heart surgery for religious reasons. They were more concerned with the potential risk of HIV/AIDS, hepatitis and other still unknown blood-borne viruses. The screening methods employed routinely by all blood banks have greatly reduced this risk to negligible levels but it is still a concern for many patients.
Another concern is the fact that a transfusion has profound effects on our body and its modulation of our immune system. These effects can manifest themselves as severe allergic reactions. Whether you receive your own blood or blood from an unrelated donor, the risk of an allergic reaction is the same. An allergic reaction can in fact occur if a patient is sensitive to the additives and preservatives used when storing his own blood donated before surgery. Inflammatory responses are also seen in patients after a transfusion with accumulation of inflammatory fluids in various organs (lungs, kidneys, muscles) and soft tissues that effectively slow down the recovery period after open heart surgery. Many patients simply don't like the idea to receive blood products "from other people".

The science behind no blood heart surgery has made impressive progress over the last decade and it is now possible to offer this option routinely in most patients.
The first step is the preparation before surgery:
- We investigate any evidence of spontaneous bleeding or anemia
- All medications that can cause bleeding are discontinued (i.e.:aspirin, coumadin, plavix, fish oil, certain herbal remedies and vitamin E), if medically safe
- Medications such as Erythropoietin or Darbopoietin, Iron and Folic Acid are given to stimulate the patient's own production of more red blood cells, if indicated. Ideally each patient considered for elective surgery should be treated to ensure a healthy hemoglobin level
- We discuss which blood fractions are acceptable or not to the individual patients
- A surgical strategy is planned to minimize the risk of bleeding while accomplishing a complete, thorough treatment of the heart condition
Second step. During surgery a variety of blood sparing techniques and technologies are employed and modified to respect patient's beliefs or preferences:
- Use of minimally invasive bloodless cardiac surgery techniques whenever possible to avoid breast bone cutting and its increased chance of postoperative bleeding. The picture below shows you a surgical scar in a young Jehovah's Witness from Florida who recently underwent a minimally invasive aortic valve replacement. The incision is placed between two ribs and heals very well.He recovered rapidly and was able to leave the hospital two days after surgery with an excellent hemoglobin level (13!).

- Extra Corporeal Circulation (the heart-lung machine) with or without blood storage. The entire blood volume can be kept in circulation at all times.
- Beating Heart Surgery technique for coronary artery bypass. It avoids using the heart-lung machine and helps us maintain a better ability to coagulate and stop bleeding after surgery.
- Blood Salvage. A "cell saver" machine like the one in the picture below collects, filters and returns the patient’s blood to his own circulation. A closed circulation loop with no storage can be maintained at all times.

- Intraoperative hemodilution: some of the patient's own blood can be removed prior to surgery and replaced with fluid. After surgery, the patient’s blood, is re-circulated into the patient’s body with the advantage of fresh, intact coagulation properties (not used in Jehovah's witnesses because the blood needs to be stored out of the circulation for an hour or two)
- Careful cell saver recycling and rinsing of any blood absorbed in surgical pads and gauze during surgery. Many surgeons unfortunately do not pay much attention to what happens to those blood soaked pads. A surgical gauze pad can absorb up 300 ml of blood which could be lost with the rest of the disposables if an effort to recover it is not routinely made. A considerable amount of blood can be returned to our patients by following the simple routine outlined in the pictures below. This way we can reach the end of the operation with virtually no blood loss.

1) A surgical gauze sponge is first rinsed in a bowl with sterile saline solution

2) As you can see, a fair amount of blood is now in the saline solution

3) The scrub nurse wrings out the gauze sponge

4) The blood and saline solution are suctioned into the cell saver where the red blood cells are washed, spun and returned to the patient in real time
- Use of synthetic (not derived from blood products!!) topical hemostatic agents help control surface bleeding Hypervolemic hemodilution: the blood volume is diluted by adding saline solution during surgery and then reconcentrated at the end
- Hypotensive anesthesia: a controlled, lower blood pressure will cause less bleeding
- Intra-operative electro-cautery or argon beam blood vessel coagulation is used to minimize blood loss.
Third step. Blood loss is minimized before and after surgery and Intensive Care Protocols are implemented to manage anemia:
- Induced Hypothermia decreases the oxygen demands in anemic patients by slowing their metabolism
- Self-transfusing drainage systems allow us to immediately recover any postoperative bloody drainage
- Tiny, pediatric test tubes are used to sample a smaller volume of blood and only for absolutely necessary tests. The picture below shows you the striking difference in size between pediatric and adult test tubes. The attention to such details contributes to our results in blood sparing strategies.

- Hyperbaric Oxygen Therapy: oxygen can be administered at a pressure higher than normal atmospheric pressure to increase oxygen content in a patient with profound anemia
