[2 cases from the practice of intensive treatment].
Two cases from the intensive treatment practice are presented: Case I--a 43-year-old woman drawn out from a state of clinical death during chronic dialysis for chronic renal failure with importunate ultrafiltration to combat the severe pulmonary edema, which led to hypoxia and cardiac arrest with functionally affected hemodynamic parameters (central venous pressure), because of centrally placed a/v fistula. Case II--a 46-year-old woman with severe drug disease and extremely critical hypotonic hyperhydration and anasarca, treated also with ultrafiltration, enhanced sodium influx and intensive application of diuretics; for 24 hours a negative fluid balance was achieved (71191 ml) until finally a relative fluid-electrolyte equilibrium was reached.
