Abstract： Objective To summarize the clinical experiences of performing extracorporeal membrane oxygenation (ECMO) on patients with heart and respiratory failure, and compare the clinical outcomes of Medtronic system and Quadrox PLS system. Methods We retrospectively analyzed the clinical data of 121 heart and respiratory failure patients who underwent ECMO treatment in Fu Wai Hospital from December 2004 to December 2009. Based on the different systems used, 121 patients were divided into two groups. In group M, there were 65 patients including 41 males and 24 females, with an age of 26.6±25.9 years; and they accepted Medtronic ECMO system treatment. In group Q, there were 56 patients including 39 males and 17 females, with an age of 32.4±23.9 years and they underwent Quadrox PLS ECMO system treatment. The evaluation of the clinical outcomes of these two different systems was based on the comparison of transmembrane pressure drop (TMPD), anticoagulation, hemolysis, plasma leakage, organ function, complication and hospital mortality between the two groups. Results Compared with group M, ECMO with Quadrox PLS system was associated with lower TMPD (at the beginning of ECMO: 15.0±6.0 mm Hg vs.28.0±5.0 mm Hg, P=0.000; 24 hours later: 16.0±5.0 mm Hg vs. 30.0±7.0 mm Hg, P=0.000) and less thrombus formation(7.1% vs.23.1%, P=0.037), less plasma leakage (0.0% vs. 50.8%, P=0.000), less hemolysis (14.3% vs. 29.2%, P=0.047). There were no significant differences between the two groups in support duration, complication rate, and hospital mortality(P gt;0.05). Conclusion Both devices have similar effects for safe clinical application, but Quadrox PLS ECMO system has a relatively high biocompatibility with lower TMPD, less plasma leakage, and thrombus formation.
