Cardiac stabilization during “off-pump” coronary revascularization (OPCAB) has been implicated in causing intraoperative hemodynamic disturbances. Stroke volume and cardiac output reductions may alter the ventilation/perfusion ratio in the lungs and compromise the gas exchange. This study was conducted to determine the impact of heart’s stabilization on arterial blood-gas profile in patients undergoing OPCAB surgery.

This study was undertaken to examine the impact of the variations of cardiac mechanical work in heart’s respiratory quotient (RQ) and venoarterial carbon dioxide difference (ΔPCO2). In twenty-seven patients undergoing coronary artery bypass grafting under extracorporeal circulation, a coronary sinus line was instituted and it’s correct position was verified by the waveform displayed in the monitor. Immediately after cannulae placement, a haemodynamic profile was obtained and simultaneous arterial and coronary sinus (a & cs) sampling for blood gas analysis was done in an ABL 720 (Radiometer Copenhagen) analyzer.
