RESUMO
Continuous arteriovenous hemofiltration(CAVH) is used to treat hemodynamically unstable patients with renal failure, refractory ascites and edema, sepsis, or ARDS patients. Patients received CAVH during a 3-year-period from March 1994 to February 1997. Their clinical findings were analyzed retrospectively, and the results were as follows; They were 6 men and 3 women from 28 to 62 years. 3 patients had ARDS, 2 patients had CHF. The remainder had SLE, liver cirrhosis, septic shock with cholangitis, diabetic ketoacidosis with pulmonary edema. The duration of treatment ranged from 30 to 50 hours, with a mean of 41.6+/-6.9 hours. The total fluid repalcement was 22.4+/-1.7L and the mean fluid loss was 3.9+/-2.6L. Changes in serum BUN, creatinine, sodium, potasium before and after treatment were not significantly diffrent. The complication of CAVH is clotting of hemofilter, hypotension, bleeding, and mild thrombocytopenia. 2 of 3 ARDS patients expired during CAVH, liver cirrhosis patient expired later due to hepatic encephalopathy, and, finally 6 patients discharged with improved conditions. In conclusion, CAVH, a safe and effective therapy in hemodynamically unstable patients with renal failure, refractory ascites and edema, sepsis, or ARDS patients.
