A Case Of Prolonged Deep Hypothermia During Cardiopulmonary Bypass

Observations made during and after prolonged deep hypothermia (7 hours between 6-20°C) are reported in a case operated for a rhinopharyngeal haemangioma with severe blood loss during cardiopulmonary bypass. Near normal numerical values of the acid-base parameters when corrected to the current temperature were aimed at. No organic damages could with certainty be described to the hypothermia itself or to the prolonged perfusion.
