Before surgery

Weeks before a bloodless procedure, physicians may prepare your child by giving them iron supplements and sometimes medications.

You and your child may be asked to see a physician a day or two before the surgery to make sure your child鈥檚 hemoglobin level is high enough to make bloodless surgery safe. If for some reason your child is anemic at that point, we may not proceed with the bloodless surgery and may move forward with a 鈥渢raditional鈥� heart surgery instead.

Blood draws during the pre-operative period are kept to a minimum. 鈥淲e draw enough to conduct the necessary tests,鈥� says Dr. Yarlagadda, 鈥渂ut we consider whether each draw is really essential. If we don鈥檛 need the blood, we leave it in the patient.鈥�

During surgery

During all open cardiothoracic surgery, a bypass machine is used to keep blood oxygenated and pumping throughout the body while the heart and lungs are temporarily taken off line. Unlike traditional bypass machines that require a lot of blood to fill the long tubes carrying the blood from body to machine and back, bloodless surgery bypass machines use much shorter and narrower-gauge 鈥渃ircuits,鈥� or tubes.

The pump may even be worn by the surgeon like an under-the-arm holster so that it remains as close to the patient as possible, minimizing the amount of blood needed to operate the machine. Minimally invasive surgical strategies and technologies also make bloodless surgery feasible for very small patients.

Inevitably, some blood will be lost during surgery. When it is, it is vacuumed up and recycled using a 鈥渃ell saver,鈥� a machine that 鈥渃leans鈥� the patient鈥檚 blood to remove any clots and then safely reintroduces it to the patient.

New medications that quickly seal up the flow of blood from incisions have helped surgeons further reduce loss.

After surgery

Dr. Yarlagadda has drastically reduced the amount of blood drawn from patients in the Pediatric Intensive Care Unit after surgery so that they can return to their normal blood levels as quickly as possible. Traditionally, 2 mm to 7 mm of a patient's blood would be drawn 24 times a day.

For a small child whose blood levels have been reduced by surgery, that is too much. If he is careful to draw only when necessary, however, Dr. Yarlagadda can reduce blood draws to three or four times a day right after surgery and then just once a day until discharge.

The advantages of bloodless surgery are significant enough鈥攁nd well enough established鈥攖hat they are quickly becoming the standard of care at the Betty Irene Moore Children鈥檚 Heart Center. 鈥淚f you can get by without using donated blood,鈥� says Dr. Yarlagadda, 鈥渨hy wouldn鈥檛 you?鈥�

Heart Center Coordination

If your child requires a complex heart surgery or interventional cardiac catheterization procedure, ask about our Heart Center Coordination Program, which can provide your family with a cardiac nurse navigator to guide you through your child鈥檚 care journey at Stanford Children鈥檚. The program is currently supporting pediatric patients with certain complex heart needs.
