Oxygenation of cardioplegic solutions: A note of caution

The Annals of Thoracic Surgery, 1991
The merits of oxygenated crystalloid cardioplegic solutions have been well established in experimental animals. The positive effects of oxygenation of Plasmalyte B (Sabax Ltd) and St. Thomas Hospital solution (Plegisol) were achieved by gassing with 95% O2/5% CO2 and 100% O2, respectively.

The Optimal Potassium Concentration in Cardioplegic Solutions

The Annals of Thoracic Surgery, 1981
High-energy phosphates provide a sensitive index of myocardial preservation. This experiment was designed to use this index in order to assess the efficacy of various potassium concentrations in a crystalloid cardioplegic solution in protecting the myocardium during hypothermic ischemic arrest.

Regional Myocardial Perfusion of Cardioplegic Solutions

The Annals of Thoracic Surgery, 1987
We compared the regional myocardial perfusion of blood cardioplegic solution (BCP) and crystalloid cardioplegic solution (CCP) in 14 mongrel dogs. Cardiopulmonary bypass was established at 28 degrees C, and a hydraulic occluder was placed around the proximal left anterior descending (LAD) coronary artery. In group 1 (N = 7) collateral coronary arteries

Maximal oxygenation of dilute blood Cardioplegic solution

The Annals of Thoracic Surgery, 1987
The content of dissolved O2 (the major source of O2 for the myocardium) of dilute blood cardioplegic solution (dBCS) varied widely when oxygenated at 4 degrees C by surface flow of O2 in a Bentley BCR-3500 cardiotomy reservoir. We have modified the system to consistently deliver maximally oxygenated dBCS to the heart.

An Intracellular-like Cardioplegic Solution

Archives of Surgery, 1980
We sought to determine the relative protective effects of an intracellular-like, calcium-bearing, crystalloid solution (ICS) and a calcium-free, extracellular-like solution (ECS). Both solutions were similar in concentrations of potassium ions (25 to 26 mEq/L), in pH (7.7 to 7.8), and in osmolarity (340 to 360 mOsm/L).

Comparison of crystalloid and sanguineous cardioplegic solutions in the dog

American Journal of Veterinary Research, 1985
SUMMARY Myocardial protection provided by 2 types of cold cardioplegic solution and by cold saline solution was compared experimentally in dogs on cardiopulmonary bypass. Techniques and solutions used simulated clinical conditions. Serial biopsies of myocardium were assayed for adenosine triphosphate, adenosine diphosphate, and adenosine monophosphate.

Preparation of Oxygenated Cold Crystalloid Cardioplegic Solution

The Annals of Thoracic Surgery, 1986
The value of oxygenated, aqueous, cold cardioplegic solutions is being evaluated at several centers. The theoretical advantages of such a solution are counterbalanced in part by the complexity and expense of the preparation and delivery systems that have been used.

Pediatric myocardial protection: a cardioplegic strategy is the “solution”

Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2004
This article describes the experimental infrastructure and subsequent successful clinical application of a comprehensive cardioplegic strategy that limits intraoperative injury and improves postoperative outcomes in pediatric patients. The infant heart is at high risk of damage from poor protection as a result of preoperative hypertrophy, cyanosis, and

Myocardial Protection by Cardioplegic Solutions

1979
The aim of myocardial protection in coronary bypass surgery is to guarantee the functional and structural integrity of the whole myo­cardium which should be independent of the preoperative myocardial and coronary conditions and the number of grafted coronary arteries.
