Since 1982, oxygenated crystalloid cardioplegia solution has become a popular method of myocardial preservation during cardiac surgery. The preferred method of oxygenated cardioplegia delivery has been the use of a recirculating delivery circuit that bubbles or films oxygen into the solution. Our present method allows us to pre-oxygenate the cardioplegia solution bags up to two weeks before using the oxygenated solution. The pO2 remains between 650-850 mmHg, and the oxygen content remains at 3.0-4.0 vol. %. The oxygenated cardioplegia maintains its sterility for as long as two weeks. The cost of oxygenating the cardioplegia is less than $1 per bag. Our delivery circuit requires no recirculating pump or sophisticated circuitry.
Key words: crystalloid cardioplegia / oxygen partial pressure / gas bubble / non-recirculating delivery system
