Their physicochemical properties differ from isoflurane, enflurane and halothane, thus requiring new technical equipment and leading to a change in anesthesiological procedures. Low-flow anesthesia with desflurane can be performed, the technical equipment is available, especially vaporizers and gas analyzers. In contrast to anesthesia with isoflurane, enflurane and halothane, the initial high-flow wash-in period with desflurane can be shorter and the vaporizer setting can remain unchanged after fresh gas flow reduction. In order to administer desflurane and sevoflurane in closed circuit technique, new technical equipment is needed. Therefore, a computer controlled anesthesia machine was modified and the feedback mechanism to maintain the end-tidal anesthetic concentration was simulated. Isoflurane, desflurane or sevoflurane needed the same time for wash-in. Wash-out was slower with isoflurane; however, the technical equipment should be adapted to increase the elimination of the new agents. The consumption of desflurane and sevoflurane is effectively reduced by low-flow and closed circuit anesthesia.","PeriodicalId":79791,"journal":{"name":"Applied cardiopulmonary pathophysiology : ACP","volume":"5 Suppl 2 ","pages":"47-57"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21022470","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}

In this institutionally approved study, thirty patients undergoing CABG were randomly assigned to three groups according to the intraoperative blood saver used during the procedure: {HAEMONETICS Cell Saver IV (n=10)--DIDECO/SHILEY STAT (n=11)--BRAT 250 (n=9)}. Anaesthesia and conduct of bypass were identical for all patients. The initial heparin dose was 300IU-kg -1 and was supplemented to maintain an activated coagulation time over 480s. The harvested blood was processed according to the procedure defined by each equipment manufacturer. The biological study was performed on the first blood sediments sampled before administering protamine to the patient. Blood cell count, residual heparinemia assessed by its anti-Xa activity using an amidolytic method {STACHROM HEPARIN--DIAGNOSTICA STAGO}, and weight of the blood sediment proteins were determined. Demographic data did not differ between groups. Despite a slight but significant difference between groups, the three devices provided virtual elimination of heparin. The total protein content was significantly higher in the BRAT 250 group. There was a highly significant positive correlation between the anti-Xa activity and total protein content. Haematologic data were within clinically acceptable ranges.","PeriodicalId":79791,"journal":{"name":"Applied cardiopulmonary pathophysiology : ACP","volume":"5 1","pages":"5-8"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21044872","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}
