Cold blood--potassium cardioplegia
L Levinsky, AB Lee Jr, KC Lee, F Tatransky, R Dockstader and G Schimert
A technique is described for providing myocardial protection utilizing
oxygenated blood that is drawn from the pump oxygenator and passed through
two disposable cardioplegic cooling coils, which are joined in series and
submerged in ice slush. A potassium-containing cardioplegic solution is run
into the oxygenated blood at the level of the cooling coils. The amount of
blood used in the blood-potassium cardioplegic mixture is controlled using
a screw clamp. This method has been used with excellent results in 150
consecutive patients undergoing aortocoronary saphenous vein bypass
grafting.
