arrhythmia vulnerability, are affected by cardioplegia during cardiopulmonary for 45 min, with or without antegrade administration of cardioplegic solution.

solution, in chemistry, homogeneous mixture mixture, in chemistry, a physical combination of two or more pure substances (i.e., elements or compounds). A mixture is distinguished from a compound, which is formed by the chemical combination of two or more pure substances in a fixed, definite proportion.

It protects the myocardium by inducing a rapid and complete diastolic arrest, minimizing myocardial energy requirements and preventing ischemic damage during the arrest phase, and minimizing or preventing reperfusion injury once coronary blood flow is restored. Cardioplegia Solution ‘A’ is a sterile nonpyrogenic solution in a Viaflex bag. It is used to induce cardiac stasis and to protect the myocardium during open heart surgery. Cardioplegia Solution ‘A’ is an isotonic crystalloid solution based on extracellular fluid ionic concentrations. 2011-09-19 Cardioplegic solution contains about 20 mmol/L of potassium and is run at a temperature of either 6–8 °C (cold cardioplegia) or at 37 °C (warm cardioplegia). From: Surgery (Oxford) , 2015 Related terms: Solution for infusion into the coronary arteries during cardiopulmonary bypass to induce cardioplegia. 4.2 Posology and method of administration A sterile aqueous solution for dilution.

Cardioplegia solution

4.2 Posology and method of administration A sterile aqueous solution for dilution. 20 ml are diluted with 1 litre of Compound Sodium Chloride Injection BPC, immediately before use. 4.3 Contraindications The mechanisms of the metabolic and ultrastructural changes that occur as a result of myocardial ischemia during cross-clamping of the aorta and the secondary injury that can occur during reperfusi Blood cardioplegia was ameliorated over time by adding several myocardial protection substrates: K⁺, Mg²⁺, Ca²⁺, allopurinol, desferrioxamine, superoxide dismutase, mannitol, polyethylene glycol, Custodiol® HTK Solution – Cardioplegia. Custodiol ® HTK (Histidine – Tryptophan – Ketoglutarate) Solution is used by leading Cardiac Surgery Centers as a cardioplegic solution worldwide. A product approved by US FDA as a Medical Device and being a Multi – Organ solution, is also the solution of organ cleaning during cardiac surgery. DESCRIPTION.

Use of cardioplegic solutions preserves myocardial energy stores, hindering electrolyte disturbances and acidosis during periods of myocardial ischemia. We designed this study to compare the efficacy and safety of Histidine-tryptophan-ketoglutarate (HTK) solution versus blood cardioplegia in coronary artery bypass graft surgery. CUSTODIOL® HTK Solution is indicated for perfusion and flushing of donor kidneys, liver, pancreas and heart prior to removal from the donor or immediately after removal from the donor. The solution is left in the organ vasculature during hypothermic storage and transportation (not for continuous perfusion) to the recipient.

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.

the process 2019-07-11 2021-04-06 Adenocaine Adenosine-lidocaine (adenocaine) cardioplegia provides an exciting alternative to depolarizing cardioplegia. Adenosine-lidocaine cardioplegia has been shown to provide a shorter time to electromechanical arrest, greater postischemic recoveries of aortic flow, a lower coronary vascular resistance during infusion, and greater MVO2 as compared to St. Thomas’ Hospital solution, while these solutions. A novel formula for inducing cardioplegia was introduced in congenital heart surgery in 1995.5,6 Led by Pedro del Nido, MD, researchers from the University of Pittsburgh patented this formula as a single dose of a modiﬁed depolarizing solution.

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.

After buffering with sodium bicarbonate it is suitable for cardiac instillation Cardioplegia Mechanism The cold solution is used to protect heart cells from dying. The presence of potassium in cold solution, reduces the membrane potential of myocardial cells and the depolarization of cells occur more rapidly.
