The dialysate was utilized with 4 patients for periods ranging from 4 months to 1 year according to a short-term recirculated dialysis schedule in closed circuit (20-40L) (2-2 1/2 hrs) on alternate days. Preliminary results are reported here with respect to the tollerance of the dialytic run and correction of the acid-base balance equilibrium. The clinical tollerance is excellent despite high dehydration rates even in patients particularly sensitive to ultrafiltration. The acidosis correction would seem to be much better with bicarbonate than with traditional dialysis. The difference is even higher if we consider the brevity of the dialysis. During the bicarbonate dialysis we do not observe any fall of the PCO2 or significant difference in PO2 in the patient's blood. The correction of acidosis probably causes the normalization of pre-dialytic potassiemia in spite the \"net\" removal of K with short dialysis is considerably less.</p>","PeriodicalId":75998,"journal":{"name":"Journal of dialysis","volume":"3 2-3","pages":"119-34"},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/08860227909063934","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11264157","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}
