Histidine-tryptophan-ketoglutarate solution (HTK) was initially introduced as a cardioplegic solution in open-heart surgery by Bretschneider in the 1970s. 20 The basic design of the solution consists of a very potent buffer, histidine, combined with two amino acids (Table 9-2). 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.
Oct 19, 2020 There are several types of blood cardioplegia that differ in their electrolyte and drug additives Table 1: Composition of cardioplegia solutions Aug 28, 2013 In addition, depending upon the type of surgery, 4–40% of patients will Currently over 99% of cardioplegic and most preservation solutions The patients were divided into two groups based on the type of cardioplegia St. Thomas Hospital solution – two types of cardioplegia in adult cardiac surgery.

Klamerus KJ, Munger MA. Eleven institutions that participated in the Coronary Artery Surgery Study (CASS) were surveyed to obtain information about the types of cardioplegic solutions used at these institutions.

Cardioplegia type was not a predictor in mechanical ventilation time and intensive care unit stay time models.
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.

For example, O'Brien clinically tested the Del Nido solution against modified Buckberg blood cardioplegia S3 , yet their solution did not have the Buckberg cardioplegia constituents that were tested in severely damaged hearts [ 4 ]. 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 Current techniques of myocardial protection during global ischemia include hypothermia, cardioplegic arrest and controlled reperfusion. To compare different types of cardioplegia and reperfusion In general, blood-based or crystalloid-based solutions are used as potassium-containing transport medium.

Each solution should be uniquely titled to avoid confusion, rather than lumping all blood cardioplegic solutions together as ‘blood cardioplegia’. For example, O'Brien clinically tested the Del Nido solution against modified Buckberg blood cardioplegia S3 , yet their solution did not have the Buckberg cardioplegia constituents that were Cold cardioplegia can be either crystalloids or blood. Crystalloids-based cardioplegia solutions contain high concentration of potassium with variable concentrations of sodium, calcium, and buffer solutions making them osmotically balanced. Each solution should be uniquely titled to avoid confusion, rather than lumping all blood cardioplegic solutions together as ‘blood cardioplegia’.
