Cardioplegia solutions may be delivered antegrade (i.e. via the coronary arteries), retrograde (i.e. via the coronary sinus, through the venous system of the heart.), or by a combination of both, as demonstrated in Figure 7.3. Figure 7.3 Cannulation and set-up for antegrade and retrograde application of cardioplegia.

Apr 28, 2016 Addition of emulsified isoflurane into cardioplegia solution protects against myocardial ischemia reperfusion injury. This protective effect might [1–2]Induction of cardiac arrest by antegrade administration of cardioplegia combined with intermittent retrograde delivery of cardioplegic solution through the CARDIOPLEGIC SOLUTION FOR CARDIAC PERFUSION It is a "core solution" intended for use only after addition of sodium bicarbonate to adjust pH prior to Nov 10, 2013 Introduction: Custodiol cardioplegia is attractive for minimally invasive Custodiol is an intracellular crystalloid cardioplegic solution used by Repolarization however is prevented by the high potassium concentration of the cardioplegic solution. Both intracellular and extracellular cardioplegic solutions Wide Selection. One Focus. Trust your cardioplegia solutions to CAPS. Cardiac surgery is a high-risk procedure that requires a carefully orchestrated team of cardioplegia.

Table 1 shows the composition of this single dose blood cardioplegia strategy. The final solution is a 4:1 blood to crystalloid mixture. The crystalloid solution is obtained by adding 40 cc of 10% Potassium chloride (80 mEq) and 30 cc of 10% NaHCO3 (30 mEq) to a 1L Ringer´s Lactate bag conaining 930 cc of the original solution.

Inducing cardiac arrest, or cardioplegia, helps protect the myocardium while providing the surgeon with a still, bloodless operative field and a flaccid heart on which to work. Cardioplegic solutions provide myocardial protection via a combination of three overlapping mechanisms: induction of chemical cardiac arrest, myocardial hypothermia, and additional protection provided by measures such as the addition of acid–base buffers, energy substrates, or oxygenated 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. 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 tested in severely damaged hearts [ 4 ].

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.

The presence of potassium in cold solution, reduces the membrane potential of myocardial cells and the depolarization of cells occur more rapidly. This depolarization causes the calcium to pump out and cells to contract more and as a result the cells feel relaxed. Cardioplegic solutions provide myocardial protection via a combination of three overlapping mechanisms: induction of chemical cardiac arrest, myocardial hypothermia, and additional protection provided by measures such as the addition of acid–base buffers, energy substrates, or oxygenated Each solution should be uniquely titled to avoid confusion, rather than lumping all blood cardioplegic solutions together as ‘blood cardioplegia’.

Methods: Sixty patients were studied between January 2017 to December 2017. Cardioplegic solution administration into the vein graft is an established method to ensure cardioplegic distribu- tion beyond coronary artery stenoses. Aug 28, 2013 Thomas's solution or Celsior preservation solutions resulted in a significant potassium-induced depolarization and loss of endothelial-derived Jul 14, 2020 Background: The use of cardioplegia solutions as a myocardial protection technique is essential during cardiac surgery with cardiopulmonary Jan 22, 2017 Albumin and glucose have also been added to some solutions to increase osmolarity.

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.

Objectives: Describe how retrograde cardioplegia is administered; Review the indications for retrograde cardioplegia The use of cardioplegia solution represents the most important strategy to protect myocardial muscle during cardiac surgery ().Cold crystalloid cardioplegia associated with mild-to-moderate hypothermia has the advantage to decrease the oxygen consumption, offers some degree of myocardial protection during period of low flow or low perfusion pressure. ical arrest’ (now termed cardioplegia) induced a cell membrane depolarization, preventing conduction of the action potential and resulted in diastolic cardiac arrest. Reversibility of arrest was easily achieved by washout of the solution. However, this elevated potassium (hyperkalemia) citrate solution was subsequently found Objective: The del Nido cardioplegia solution provides a long period of arrest with single dose as compare to St. Thomas cardioplegia solution. In our study we compared outcomes of del Nido and St. Thomas cardioplegia in adult open cardiac surgeries. Methods: Sixty patients were studied between January 2017 to December 2017.

Commonly referred to as ‘‘del Nido solution,’’ this blood and crystalloid Del Nido cardioplegia solution offers prolonged cardiac protection with single-dose administration; this is particularly interesting for aortic root surgery. However, there is a scarcity of data supporting its safety in adults undergoing complex cardiac surgery, such as aortic root repair.
