Title: Total cardiopulmonary bypass with the Lande-Edwards membrane oxygenator
Abstract: Use of a commercially available disposable membrane oxygenator for total body perfusion and open heart surgery has been evaluated in clinical cases. Preliminary data indicate excellent oxygenation and minimal trauma to blood under conditions requiring prolonged perfusion. Two perfusion circuits are described. One has an intrinsic recirculating circuit to minimize pressure exerted on the membrane and multiple oxygenator units combined in series. The other utilizes gravity venous drainage directly into the multiple oxygenator units which are arranged in parallel to decrease resistance to gravity flow. Eighteen patients were perfused with the first method. Three have been perfused with the second. Physiologic data from both groups are presented. The technical advantages and disadvantages of each of the methods are described. Both methods are adequate for perfusion. The latter method of perfusion seems more desirable because the technicians have 1 less pump to operate and therefore can be more accurate in their control of total body perfusion.
