Nevertheless the discussion concerning the importance of co- or counterpulsation isn't yet finished. Using a theoretical model of the cardiovascular system, the influence of a LVAD triggered to co- and counterpulsation will be discussed. The theoretically obtained results are compared to a series of six experiments in calves, where the influence of LVAD-pumping in co- and counterpulsation pumping mode was investigated. Additional benefits were seen compared to the copulsation pump method: there was more reduction of the cardiac stroke work, afterload and an increase of the diastolic pressure, which is important for the coronary blood flow. In order to verify the benefits of the additional reduction of pressure work a small series of animal experiments was performed.</p>","PeriodicalId":77869,"journal":{"name":"Life support systems : the journal of the European Society for Artificial Organs","volume":"5 4","pages":"307-15"},"PeriodicalIF":0.0,"publicationDate":"1987-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14556372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observed the incidence and analysed side effects (SE) occurring during TPE considering the technology of plasma removal. Full data were available for 63 patients. Seven hundred and eighteen TPE were performed. Centrifugation was used in 594 PE (82.7 per cent) with intermittent flow centrifugation (IFC) 320 times (44.5 per cent) and continuous flow centrifugation (CFC) 274 times (38.2 per cent). Filtration (F) was used in 124 sessions (17.3 per cent). Replacement fluid was 4 per cent albumin in 650 TPE and fresh frozen plasma (FFP) in 89 TPE. A total of two hundred and eleven SE were reported in 53 patients (84.1 per cent) during 173 TPE (24.1 per cent). Forty-six TPE were temporarily stopped because of SE (6.4 per cent). The mean volumes of removed plasma (ml/kg/TPE) were: 60.7 +/- 8.7 ml/kg when CFC was used 54.5 +/- 20 ml/kg with F and 52.5 +/- 9.6 ml/kg with IFC (n.s.) Main SE were: technical difficulties in 80 TPE, moderate or severe hypotension in 47, allergy to replacement fluid in 39. Hepatitis B antigen appeared in one patient.
