Three cases of uraemic haemorrhagic pericarditis observed during haemodialysis treatment are described. The condition is explained with uraemic toxicosis, cyclic heparinaemia resulting from dialysis, deficient thrombocyte function, and decreased capillary resistance. The clinical appearance of haemorrhagic pericarditis was not typical in any of the cases. Two patients died, while in one patient partial pericardiectomy was performed with success.
The efficiency of peritoneal dialysis by the use of hyperosmolar dialyzing fluid (680 mOsm/1) was studied in 7 patients with chronic renal failure. The results were referred to the control values obtained in the first and in the terminal periods. In the course of treatment by means of the solution of high osmolarity the clearance of small- and medium-molecular substances increased. A significant increase in ultrafiltration was demonstrable. Protein loss and elevation of the blood glucose levels were noted as side-effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
