Compared with multidose cardioplegia, there were advantages in adopting single-dose cardioplegia only in the form of DN solution. Indeed, DN was able to reduce operative times, reperfusion fibrillation, and peak of cardiac enzymes. These effects were not replicated by HTK, which on the contrary increased CPB time and reperfusion fibrillation.

Custodial-HTK solution is an intracellular cardioplegic solution containing histidine, tryptophan and ketoglutarate. Aim: we compared the myocardial protective effects of 3 types of cardioplegia solution: The histidine–tryptophan– ketoglutarate (HTK) solution, blood and St.Thomas cardioplegia in pediatric cardiac surgery.

Cardioplegia Solution ‘A’ is an isotonic crystalloid solution based on extracellular fluid ionic concentrations. Approximate osmolality is 275 mOsm/kg and approximate pH is 3.7. Cardioplegia Solution ‘A’ requires the aseptic addition of 10 mL Sodium Bicarbonate 8.4% w/v Injection B.P. prior to use to adjust the pH to 7.4-7.8.

Cardioplegia is used on CPB to induce an arrest of the heart. Components of cardioplegia solution are varied in different institutions but include potassium to achieve diastolic arrest. A cross-clamp is applied to the ascending aorta, and the cardioplegia is administered into the aortic root in an antegrade fashion via the coronary ostia. Current techniques of myocardial protection during global ischemia include hypothermia, cardioplegic arrest and controlled reperfusion. To compare different types of cardioplegia and reperfusion 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. Crystalloid solutions were the first cardioplegia solutions to be widely adopted and both “intracellular” and “extracellular” solutions are associated with excellent results.

The solution used in antegrade Cardioplegia may be blood or crystalloid solution. The pressure required for the injection of solution is 60 to 100 mm Hg. The arresting time in antegrade Cardioplegia is fast and may be ranging between 30 to 60 sec. if there is any delay in cardiac arrest then following reasons could be behind it; Problem in delivery system and AR is unrecognized. The histidine-tryptophan-ketoglutarate (HTK) solution was first introduced in the 1970s as a cardioplegic solution in open heart surgery. 49 The HTK solution is increasingly being used by some centers as a preservation solution for kidneys. Some cardioplegias, such as del Nido or Histidine-Tryptophan-Ketoglutamate solutions, offer an advantage over blood and other crystalloid cardioplegia as they only require one administration during short cardiac surgeries, compared to multiple hits required by blood and other crystalloid. Alternatives to cardioplegia The patients were randomized in three groups according to the characteristics of cardioplegia and reperfusion: cold blood cardioplegia with unmodified blood reperfusion (control group, 11 patients), crystalloid cardioplegia and reperfusion (Hôpital Lariboisière protocol, 11 patients) and crystalloid cardioplegia with allopurinol enriched blood reperfusion (Hôpital Broussais protocol, 11 patients).

(CPB) priming volume and cardioplegia types of cardioplegia solution. In 1990, Dr. del Nido and researchers at the University of Pittsburg developed a cardioplegia solution, a mixture of long-acting blood and crystalloids, especially for pediatric patients. Changes have been made in the original solution, and is currently known Crystalloid solution has traditionally been used as a vehicle for cardioplegia solution; however, laboratory and clinical studies have demonstrated favorable effects of blood-based cardioplegia solution.

In the 1970s, however, Buckberg introduced the concept of “blood cardioplegia.”. Blood v/s Crystalloid cardioplegia Crystalloid cardioplegia: these solutions contain minimal amounts (0.6 mL/100 mL at a PO2 of 100 mm Hg at a temperature of 10° C) of dissolved oxygen, whereas the myocardium consumes 0.33 mL of oxygen per 100 g at 15° C. Because even a short period of ischemia results in the gradual accumulation of oxygen debt, moderate to severe myocardial hypothermia is Sterile Concentrate for Cardioplegia Infusion is used during heart surgery to induce cardioplegia.

Blood supply to the heart arises from the aortic root through coronary arteries. Cardioplegia in diastole ensures that the heart does not use up the valuable energy stores (adenosine triphosphate). Blood is commonly added to this solution in varying amounts from 0 to 100%. Objectives: The del Nido cardioplegia solution has been used extensively in congenital heart surgery for more than 20 years and more recently for adults. This randomized controlled trial examined whether expanding this technique to adult cardiac surgery confers benefits in surgical workflow and clinical outcome compared with blood-based cardioplegia. To compare different types of cardioplegia and reperfusion techniques we measured the levels of adenine nucleotides and malondialdehyde (MDA, as free radical activity) in 33 patients undergoing 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-. Na+. B The results suggest that high molecular colloidal cardioplegia with HES-solution is associated with higher hemodilution during and after cardiopulmonary bypass and significantly increases the consumption of donor blood products.
