Fourrier analysis demonstrate EEG slowing after circulatory arrest at 20 degrees C.

The electroencephalographic (EEG) monitoring in infants and children submitted to cardiac surgery under circulatory arrest (CA) and deep hypothermia (20 degrees C) (DH) is usually performed by display or record without analysis. These data disclose the reappearance of EEG activity but give no qualitative analysis of EEG recovery after CA. The electrical activity of the brain was monitored in these conditions by spectral analysis (fast Fourrier transformation with on-line processing).

Haemodynamic effects of midazolam in the anaesthetized patient with coronary artery disease.

The haemodynamic effects of midazolam 0.25 mg/kg administered intravenously were studied in eight anaesthetized patients suffering from coronary artery disease. Heart rate, systemic and pulmonary pressures, right atrial pressure, capillary pressure and cardiac output were measured 2, 5, 8 and 12 min after injection of midazolam and were compared with reference values collected before the commencement of the haemodynamic test.
