How do you ReVerse cardioplegia?

How do you ReVerse cardioplegia?

The ReVerse cardioplegia circuit system is a description of a two-pump cardioplegia circuit which is adaptable to either blood or crystalloid cardioplegia. The change from one mode to another requires a manoeuvre of two clamps, allowing the blood solution to travel through shunt tubing into the apposite pumphead.

What is the purpose of cardioplegia?

Cardioplegia is an essential component of cardiopulmonary bypass and with the primary goal to reduce myocardial oxygen demand by creating electrical quiescence and cooling the heart to reduce the ischemic effects of being on bypass.

How do you give cardioplegia?

Anterograde cardioplegia is administered into a small cannula placed in the ascending aorta or directly into the coronary ostia. Retrograde cardioplegia is delivered through a catheter placed through the right atrium into the coronary sinus. Cardioplegia is then delivered into the venous system of the heart.

Can triple bypass surgery be minimally invasive?

Heart bypass surgery creates a new route, called a bypass, for blood and oxygen to reach your heart. Minimally invasive coronary (heart) artery bypass can be done without stopping the heart. Therefore, you do not need to be put on a heart-lung machine for this procedure.

What are the types of cardioplegia?

type of cardioplegia – blood cardioplegia (BL) vs. crystalloid cardioplegia (CR = St. Thomas cardioplegia + Fresenius cardioplegia) = “Cardiopl_double”; or blood cardioplegia vs. St.

Why potassium is used in cardioplegia?

Chemically, the high potassium concentration present in most cardioplegic solutions decreases the membrane resting potential of cardiac cells. The normal resting potential of ventricular myocytes is about -90 mV.

What cardioplegia contains?

Each 100 mL of solution contains Calcium Chloride Dihydrate USP 17.6 mg, Magnesium Chloride, Hexahydrate USP 325.3 mg, Potassium Chloride USP 119.3 mg and Sodium Chloride USP 643 mg in Water for Injection, USP. May contain HCl and/or NaOH for pH adjustment.

Can they do bypass surgery without opening chest?

Surgeons perform the procedure using long instruments. Minimally invasive heart surgery involves making small incisions in the right side of the chest to reach the heart between the ribs, rather than cutting through the breastbone, as is done in open-heart surgery.

What is cardioplegia made of?

The word cardioplegia combines the Greek cardio meaning the “heart”, and plegia “paralysis”. Technically, this means arresting or stopping the heart so that surgical procedures can be done in a still and bloodless field.

What is retrograde cardioplegia?

Retrograde cannulae are designed to deliver cardioplegia solution to the heart via the coronary sinus in the reverse direction of normal blood flow (retrograde perfusion). These cannulae are offered in either auto inflating or manual inflating cuff models.

What are cardioplegic drugs?

Cardioplegic Description. Baxter Cardioplegic Solution is a sterile, nonpyrogenic, essentially isotonic, formulation of electrolytes in Water for Injection, USP. It is a “core solution” intended for use only after addition of sodium bicarbonate to adjust pH prior to administration.
