Cardiac Output and affect on renal function
by Cynthia, Sep 26, 2000 12:00AM
My father has endstage cardiac failure,minimal triscupid valve reguritation and wide-open mitral regurg.(4+) His ejection fraction by heart cath was 20%. He also has TVD. He was evaluated at a local hospital and was found not to be a surgical candidate. Two weeks ago my dad was considered to be too dry by his lab work. His BUN was 80 and his CREATINE was 2.5. His other lab work was worrisome since his CLORIDE was 70 and blood CO2 was 34. How can a person be "too dry" and not have dark concentrated urine. My father's intake would be 1500cc and his output would be double. The color would be light yellow. At the present time my dad has been off diuretics and his labwork has improved somewhat, but now I am worried since he has no protection of any lasix or vasotec. Thankyou for your time.

The urine does not always look concentrated when someone is "dry." It is reasonable to withhold the Lasix until his kidney tests are better - as long as he is not accumulating fluid this should not be a problem. His heart failure is going to continually predispose him to kidney failure, so his kidney function will need to be closely monitored.
