| Abstract: | Blood oxygenation was studied in patients undergoing cardiopulmonary bypass using the Rygg-Kyvsgaard bubble oxygenator. Oxygenation was satisfactory in perfusions carried out at normothermia and during hypothermia. During the rewarming phase of hypothermic perfusions hypoxaemia occurred. This could be prevented by a ganglion blocking agent (trimetaphan) given during the cooling phase. |
