These pioneers were drawn from numerous disciplines that included dialysis technicians, cardiovascular research laboratories, and allied health fields, yet were unified through a common goal: A commitment to grasp a fuller understanding of the intricacies of blood flow outside of the body. They were unencumbered by neither the temptations of finance, nor by ego, since cardiac surgery, with the use of the heart-lung machine, had yet to experience the tremendous growth that soon followed. Having joined the field since that time, I can only summize that their motivations were genuine—focused totally upon the unifying goal of improving patient care. Regardless, they ushered in a new era with the creation of the first formal publication dedicated to the field of perfusion: the Journal of ExtraCorporeal Technology.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133635058","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}

Methods: On Langendorff apparatus the hearts underwent 30 minutes of global normothermic ischemia followed by 30 minutes of reperfusion. 52 isolated hearts of 3–4 weeks old immature rabbits were divided into four groups randomly. During ischemia, three different cardioplegic solutions were administered intermittently by infusion every 15 minutes (20–25 ml every time) Group I control (n=13),; Group II: K-H solution with potassium (16 mmol/L) (n=13) ; Group III: K-H solution with potassium (16 mmol/L) and pinacidil (50 m mol/L) (n=13); Group IV: K-H solution with potassium (16 mmol/L), pinacidil(50 m mol/L) and glibenclamide (10 m mol/L) (n=13). The pre and postischemic myocardial function were assessed by the percentage recovery of left ventricular developed pressure (LVDP), left ventricular end-diastolic pressure (LVEDP), both positive and negative peak first derivative of left ventricular pressures(± dp/ptmax), coronary flow(CF), CK, LDH, AST in coronary sinus venous effluent and by myocardial ultrastructural changes. Results: Before myocardial ischemia, there were no significant difference in all above mentioned parameters in four groups. Postischemic recovery of LVDP, LVEDP, ± dp/dtmax, CF, the level of CK, LDH, AST and myocardial ultrastructural changes were better in group III than that in three other groups.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133995260","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}

It is this protein layer that interacts directly with components of the coagulation and inflammatory systems. Fibrinogen, capable of platelet binding and activation, is a particularly important protein in determining a material’s biocompatibility. Hydrophobic materials tend to have a greater affinity for fibrinogen, making them less biocompatible than hydrophilic materials. We compared the hydrophobicity of three different heparin-coated polyvinylchloride (PVC) tubing preparations with uncoated PVC tubing. We also determined if there would be a difference in the applied solution; water, an ionic solution (saline), and a protein solution (fresh frozen plasma). Hydrophobicity was quantified with five separate measurements of contact angles of water, saline, and plasma, and droplet spread diameter of water and saline. We found that Duraflo II displayed hydrophobicity similar to that of uncoated PVC tubing (initial contact angles of water were 78.0 ± 1.1 and 79.6 ± 0.6 degrees, respectively). Carmeda and 3M heparin-coated tubings displayed significantly (p < .01) less hydrophobicity (initial contact angles of water were 59.8 ± 2.1 and 39.6 ± 1.9, respectively). Three minutes after initial contact, the 3M heparin coating was the only preparation that remained significantly (p < .01) less hydrophobic than the uncoated PVC. These data suggest that 3M heparin-coated PVC is the most biocompatible of the tubings we examined, followed by Carmeda, Duraflo II, and the untreated PVC tubing.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115178541","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}

During CPB, the amount of heparin required to maintain an activated clotting time greater than 480 sec was significantly reduced following the administration of AT III concentrate (p = .000). The average increase in the ACT was 176 sec following the administration of AT III concentrate (p = .000). Thirteen of 44 patients did not require any additional heparin for the duration of CPB after AT III therapy. AT III concentrate seemed to be efficacious in the treatment of heparin resistance attributable to presumed AT III deficiency. Moreover, the reduction in heparin requirements following administration of AT III concentrate may reduce postoperative bleeding associated with heparin rebound, protamine requirements, and its associated complications and threat of intravascular coagulation during CPB.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128326045","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}
