2. 1. Presence of microemboli during haemodialysis and methods to reduce the exposure to microbubbles

   Author : Forsberg Ulf; Bernd Stegmayr; Per Jonsson; Ingela Fehrman Ekholm; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; in vivo; microemboli; microbubbles; dialyzer; air trap; venous chamber;

   Abstract : Despite chronic dialysis treatment, patients with end stage renal disease undergoing maintenance haemodialysis (HD) remain at a substantially increased risk of morbidity. Previous reports using Doppler ultrasound (DU) during HD have revealed microembolic signals (ME) in the venous circulation. READ MORE

4. 2. Safety and biological aspects of present techniques of haemodialysis

   Author : Per Jonsson; Hans Dietrich Polaschegg; Umeå universitet; []
   Keywords : haemodialysis; safety; leakage current; central dialysis catheter; microbubbles; microemboli; air contamination; transfusion medicine; transfusionsmedicin;

   Abstract : Introduction: Haemodialysis (HD) is a treatment in which blood from the patient is lead through a tubing system into a dialysis device in a extracorporeal circuit. This circuit contains semipermeable membranes (dialyzer). Blood with uraemic toxins flows on one side, and a salt solution flows on the other side. READ MORE

5. 3. Aspects of retransfusion of shed blood in cardiac surgery

   Author : Björn Brondén; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CABG; cardiotomy suction; lipid microemboli; porcine study; clinical study; cystatin C; creatinine; iohexol clearance; outcome; retransfusion; transfusion; blood.;

   Abstract : The use of cardiotomy suction during open heart surgery with cardiopulmonary bypass (CPB) has a long tradition and often regarded as mandatory. Recently, studies have described potentially negative effects of cardiotomy suction with activation of the complement system, enhanced inflammatory response, hemolysis and coagulopathy. READ MORE

6. 4. Fat contamination of pericardial suction blood in cardiac surgery : clinical and experimental studies in perspectives of transfusion logistics

   Author : Micael Appelblad; Gunnar Engström; Krister Lindmark; Anders Jeppsson; Umeå universitet; []
   Keywords : Surgery; blood transfusion; cardiopulmonary bypass; pericardial suction blood; fat contamination; lipid microemboli; density separation; surface adsorption; Kirurgi; Surgery; kirurgi;

   Abstract : Introduction: During cardiac surgery aided by cardiopulmonary bypass (CPB) the autotransfusion of pericardial suction blood (PSB) is regarded mandatory to limit allogeneic blood exposure. PSB is however proposed as a source of lipid microemboli and to contribute to brain damage. READ MORE

7. 5. New Intraoperative Techniques to Improve Advanced Aortic Root Surgery

   Author : Faleh Alrashidi; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Modified Ross Operation; Aortic Root surgery; Microemboli signals MES ; Transcranial Doppler TCD ; Acute plateletphersis APP ; Transesophageal echocardiography TEE ; de-airing;

   Abstract : Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation.
