How do you induce cardioplegia?
[1] Cardioplegia varies by composition, delivery methods, temperature, and additives; however, all solutions must include potassium chloride (15-35 meq/L) important for inducing cardiac arrest, and other electrolytes such as Mg2+, low-dose Ca2+, Cl-.
How does Custodiol cardioplegia work?
Custodiol® solution, also called histidine-tryptophan-ketoglutarate (HTK) or Bretschneider’s solution, is a particular kind of long-acting intracellular crystalloid cardioplegia (CCP) that differs from other extracellular cardioplegic solutions because of its low sodium and potassium content that induce the diastolic …
How does cardioplegia work?
Cardioplegia lowers the metabolic rate of the heart muscle, thereby preventing cell death during the ischemic period of time.
What is del Nido cardioplegia?
The del Nido cardioplegia is delivered with 20% by volume fully oxygenated patient blood, which supports aerobic metabolism for a finite period of time and provides buffering properties to promote anaerobic glycolysis as well.
What is cardioplegia infusion?

What is cardioplegia delivery system?
Abstract. Blood cardioplegia delivery systems are employed in most pediatric open heart cases to arrest the heart and keep it preserved during aortic cross-clamping. They are also used as part of a modified ultrafiltration system at the end of cardiopulmonary bypass.
What is Custodiol solution?
Histidine-tryptophan-ketoglutarate, or Custodiol HTK solution, is a high-flow, low-potassium preservation solution used for organ transplantation. The composition of HTK is similar to that of extracellular fluid. All of the components of HTK occur naturally in the body.
What is St Thomas cardioplegia?
Thomas’ Hospital cardioplegic solution number 2. This cardioplegic solution (NaCl 110.0 mM, NaHCO3 10.0 mM, KCl 16.0 mM, MgCl2 16.0 mM, CaCl2 1.2 mM, pH 7.8) is designed for routine clinical use combining optimal protection with simplicity of formulation and administration/infusion.
When should I Redose del Nido cardioplegia?
A multitude of studies have demonstrated equivalent myocardial protec- tion compared with conventional cold blood cardioplegia in adult cardiac surgery, with the advantage of a single dosing regimen. Expert opinion suggests redosing if the ischemic time is likely to extend much beyond 90 mi- nutes.
Where is cardioplegia given?
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.
What is cardioplegia solution?
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.
What is University of Wisconsin solution?
Belzer UW® Cold Storage Solution is intended for flushing and cold storage of kidney, liver and pancreas organs at the time of their removal from the organ donor in preparation for storage, transportation and eventual transplantation into a donor recipient.
