In adult cardiopulmonary bypass surgery, vacuum assisted venous drainage has become a popular technique to augment venous return to the bypass circuit. The application of this technique in neonatal cardiopulmonary bypass surgery could be beneficial to the further miniaturization of neonatal circuitry by coupling radical repositioning of the oxygenator and pump console with decreasing line length.
This report communicates the use of an investigational, vacuum assisted venous drainage neonatal circuit that is positioned at patient level utilizing a modified pump console with elevated double head twin roller pumps. The circuit, including the oxygenator, arterial line, venous line, raceway tubing, and a functional level in the venous reservoir has a priming volume of 107 ml. Initial bench and animal tests have demonstrated that this technique may be clinically feasible in CPB applications. With vacuum assisted venous drainage, the goal of asanguinous neonatal cardiac surgery could become a reality. Safety issues must be adequately addressed to ensure that this technique does not impose unacceptable risks.
