Non-invasive continuous haemodynamic and PETCO2 monitoring during peroperative cardiac arrest.

摘要: We describe a cardiac arrest which occurred during general anaesthesia in the prone position for surgical correction of lumbar kyphosis patient with Marfan's syndrome. Peroperative monitoring was routine ECG, non-invasive arterial pressure, oximetry, PETCO2 and central venous plus aortic blood flow systolic time intervals via an oesophageal echo-Doppler device. Forty-five minutes after start surgery, sudden decrease followed by suggested acute failure despite continuation ECG signal. Initial CPR produced slight increase PETCO2. When turned to supine legs elevated, chest compression more efficient spontaneous circulation rapidly restored. Circulatory could be explained incompletely treated hypovolaemia, or myocardial depression (decrease lengthened pre-ejection period) combined excessive hypotension syndrome, thus compromising coronary producing ST segment depression. Continuous proved valuable early detection treatment circulatory evaluation efficiency peroperative CPR.
