The adrenal gland in extracorporeal circulation
<p>Due to the large volume and often conflicting results reported on postoperative endocrinological changes, the practicing surgeon has difficulty in finding applicable principles. A knowledge of these principles is however necessary for an understanding of the mechanisms responsible for survival …

Extracorporeal Circulation: Effect of Long-Term (24-Hour) Circulation on Blood Components
Extracorporeal circulation damages blood and causes harmful side effects such as stroke and/or systemic inflammatory response in patients. Reactions of blood components to extracorporeal circulation include complement and inflammatory reactions, coagulation and thrombogenesis, frank hemolysis, and …

History and Technique of Operation of the Mark G.K. Gibbon Type Pump-Oxygenator
… lesions previously considered inoperable. Only extracorporeal circulation affords the development of techniques of cardiac surgery for the repair of certain congenital and acquired anomalies.

Closed mitral valvotomy in pregnancy
… the foetus and the mother. For most procedures extracorporeal circulation and heparinization are necessary and adds to the · adverse effects of the operation. Closed mitral valvotomy, however, is an excellent low risk operative procedure in patients with tight mitral stenosis without causing …

Evaluierung der Troponin-I-Freisetzung in der kardialen Lymphe bei herzchirurgischen Eingriffen unter Einsatz des extrakorporalen Kreislaufes
Extracorporeal circulation (ECC) induces a systemic inflammatory response and a perioperative myocardial damage (PMD) leading to postoperative myocardial dysfunction. The cardiac lymphatic system is because of its origin in the interstitial space of the heart, more sensitive than arterial and …

Biokompatibilitätsuntersuchungen an Originaldialysatoren in einem In-vitro-Dialyse-Rezirkulationsmodell unter besonderer Berücksichtigung von Faktor XIIa-C1-Inhibitor, einem Marker für die Aktivierung des Kontaktphasensystems
In a novel full-scale in-vitro recirculation dialysis model the influence of dialysis membranes (Cuprophan® and Polysulfone) on biocompatibility parameters was investigated. Thrombin-antithrombin complex (TAT), platelet loss, platelet factor 4 and C5a were measured to detect activation of the …

Der Einfluss von laminaren Strömungen und Sekundärströmungen im Taylor-Couette-System auf die Thrombozyten
… changes in blood vessel or tube size e.g. in extracorporeal circulation generate such vortices. So far platelet activation mechanism in these regions are merely investigated. Therefore a Taylor-Couette flow model was developed to generate defined blood flow either with laminar or vortical flow …

Bio-artificial liver support system : an evaluation of models used in demonstrating or improving metabolic and clinical efficacy
… (BALSS). This technology is composed of an extracorporeal circulation system incorporating a bioreactor that contains parenchymal liver cells (hepatocytes) to perform the detoxifying, transforming and synthetic properties of a liver. However, the development of a BALSS holds particular …

Biotransformation of blood long-chain fatty acids and oxylipins in peripheral tissue during hemodialysis
… altered in dialysis patients and influenced by extracorporeal circulation. In order to pro-vide novel insights into biotransformation and/or bioaccumulation of these metabolites in peripheral tissue, we conducted a targeted lipidomic study and tested the hypothesis that arterio–venous (A–V) …

Tierexperimentelle Untersuchungen zu Praktikabilität und Hämokompatibilität einer miniaturisierten extrakorporalen Membranoxygenierung
… lung damage and increases mortality. With extracorporeal membrane oxygenation using capillary membrane oxygenators specialized centers have the possibility to provide sufficient gas exchange in severe ARDS with life-threatening hypoxemia despite optimal conservative treatment. The standard …

Totale antioxidative Kapazität bei am Herzen operierten Kindern
… anesthesia with pure oxygen ventilation and not extracorporeal circulation with ischemia - reperfusion is related to a significant decrease of the total anti - oxidant capacity of children undergoing cardiac surgery. 2. The decrease of the total anti - oxidant capacity after the oxygenation is …

Expression des 'Vascular endothelial growth factor' bei Kindern mit angeborenem Herzfehler : Einfluss der präoperativen Hypoxämie und der Herzoperation
… 27 patients, who underwent heart surgery with extracorporeal circulation (ECC), were divided into 2 groups: the C-CHD group (n = 15) and the A-CHD group (n = 12). Median age of the whole study population was 4,5 months (Range 0,3 - 19,5 months). Median age was 5,0 (0,3 - 19,5) months in the …

Factores de riesgo para convulsiones tras cirugía cardiaca con acido tranexamico: estudio de casos y controles, FCI
La cirugía cardiaca con circulación extracorpórea tiene riesgo de lesión del sistema nervioso central que impacta negativamente el desenlace postoperatorio. Su espectro es variable siendo lo más frecuente la lesión isquémica. Sin embargo esta no es la única complicación neurológica, las …

Zur Frage der Stofftransporteigenschaften von Oxygenatorhohlfasermembranen bezüglich der Durchlässigkeit für Fluide und Narkosegase
… for cardiopulmonary bypasses (CPB) and extracorporeal life support (ECLS). Membrane oxygenators with silicone plates may also be used. During long-term use of PP membrane oxygenators, plasma leakage is possible due to a variety of factors. The PMP membrane oxygenators developed to avoid …
