Background: Central venous-arterial carbon dioxide (CVA-CO2) tension gradient was related to low cardiac output after coronary surgery. The objective of this study was to assess the correlation between CVA-CO2 tension gradient and oxygen delivery (DO2) changes following fluid therapy in coronary surgery.
Methods: A prospective interventional study was conducted in a cardiac surgery intensive care unit. Forty consecutive sedated and mechanically ventilated adult patients, with a cardiac index < 2.3 L/min/m² and a pulmonary artery occlusion pressure ≤ 12 mmHg following coronary surgery, were included. All patients received a 500 ml bolus of an isotonic crystalloid solution over 20 min. Concomitant hemodynamic parameters, arterial and central venous blood gases were measured before (T0) and after (T1) volume loading. Means were compare.. View More»
