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). 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 cardiac arrest through an hyperpolarization of the myocyte plasma membrane. 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.

To compare different types of cardioplegia and reperfusion In general, blood-based or crystalloid-based solutions are used as potassium-containing transport medium. Blood cardioplegia is mixed in a ratio of 1 : 4 (1 part of crystalloid solution and 4 parts of blood); crystalloid solutions may be of intracellular type (Custadiol) or extracellular type (Plegisol). Specific details are given in Table 1. Crystalloid cardioplegia with an extracellular fluid for- mulation is widely used for donor heart protection. A survey of 109 transplant programs yielded 62 replies with 42% of respondents using variations of extracellular solution and 45% using the dextrose and mannitol-based Stanford solution.

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. 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.
When solution is introduced into the aortic root (with an aortic cross-clamp on the distal aorta to limit systemic circulation), this is called antegrade cardioplegia. When introduced into the coronary sinus, it is called retrograde cardioplegia. When the cardioplegic solution is entered into the circulation via main aortic root which is proximal to aortic x-root then this is known as antegrade Cardioplegia. 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.

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. Caedioplegua Delivery System Market can be segmented by Crystalloid Solution Delivery System, Blood Cardioplegia Delivery System, Microplegia Delivery System and other product types which is used by Hospitals, Cardiac Centers, Ambulatory Surgical Centers. Kotani and colleagues collected data from 56 members of the Congenital Heart Surgeons’ Society in North America and found marked variation in the type of cardioplegia used. 8 Whilst blood-based cardioplegia was preferred by 86% of respondents, with del Nido solution (38%) the most popular, the next most frequent was ‘other’ (34%), custom-mixed solutions unique to an individual centre.
