Efficacy of the RemoweLL cardiotomy reservoir for Fat and Leucocyte removal from shed mediastinal blood: a randomized controlled trial. ABSTRACT (176 words) Introduction Re-transfusion of lipid particles and activated leucocytes with shed mediastinal blood (SMB) can aggravate cardiopulmonary bypass-associated inflammation and increase the embolic load. This study evaluated the fat and leucocyte removal capacity of the RemoweLL cardiotomy reservoir. Methods Forty-five patients undergoing elective on-pump cardiac surgery were randomly allocated to filtration of SMB using the RemoweLL or the Admiral cardiotomy reservoir. The primary outcome was the drop in leucocytes and lipid particles obtained with the two filters. The effect of the filters on other blood cells and inflammatory mediators such as myeloperoxidase (MPO) was also assessed. Results The RemoweLL cardiotomy filter removed 16.5 % of the leucocytes (P < 0.001) while no significant removal of leucocytes was observed with the Admiral (P = 0.48). The percentage reductions in lipid particles were similar in the two groups (26% vs 23 %, P = 0.2). Both filters similarly affected the level of MPO (P = 0.71). Discussion The RemoweLL filter more effectively removed leucocytes from SMB than the Admiral. It offered no advantage in term of lipid particle clearance. [less ▲]

BACKGROUND: Protective lung ventilation is recommended in patients with acute respiratory distress syndrome (ARDS) to minimize additional injuries to the lung. However, hypercapnic acidosis resulting from ventilation at lower tidal volume enhances pulmonary hypertension and might induce right ventricular (RV) failure. We investigated if extracorporeal veno-venous CO2 removal therapy could have beneficial effects on pulmonary circulation and RV function. METHODS: This study was performed on an experimental model of ARDS obtained in eight anaesthetized pigs connected to a volume-cycled ventilator. A micromanometer-tipped catheter was inserted into the main pulmonary artery and an admittance micromanometer-tipped catheter was inserted into the right ventricle. RV-arterial coupling was derived from RV pressure-volume loops. ARDS was obtained by repeated bronchoalveolar lavage. Protective ventilation was then achieved, and the pigs were connected to a pump-driven extracorporeal membrane oxygenator (PALP, Maquet, Germany) in order to achieve CO2 removal. RESULTS: ARDS induced severe hypercapnic acidosis. Systolic pulmonary artery pressure significantly increased from 29.6 ± 1.8 to 43.9 ± 2.0 mmHg (P < 0.001). After the PALP was started, acidosis was corrected and normocarbia was maintained despite protective ventilation. Pulmonary artery pressure significantly decreased to 31.6 ± 3.2 mmHg (P < 0.001) and RV-arterial coupling significantly improved (RV-arterial coupling index = 1.03 ± 0.33 vs. 0.55 ± 0.41, P < 0.05). CONCLUSION: Veno-venous CO2 removal therapy enabled protective ventilation while maintaining normocarbia during ARDS. CO2 removal decreased pulmonary hypertension and improved RV function. This technique may be an effective lung- and RV-protective adjunct to mechanical ventilation. [less ▲]
