Study summary

In double-blind clinical trial, determine renal recovery with two different furosemide strategies in patients with type 1 cardiorenal syndrome.

Read the detailed description

In a patient with type 1 cardiorenal syndrome, we tried to compare two Furosemide strategies: both with a morning bolus, and randomized in two groups:

Group A: Furosemide 80 mg every 24 hrs (morning) intravenously every 24 hrs for 4 consecutive days, additionally:

  • Day 1 furosemide 100mg / day infused with 100cc of Hartmann solution
  • Day 2 Furosemide 200mg / day infused with 100cc of Hartmann solution
  • Day 3 Furosemide 300mg / day infused with 100cc of Hartmann solution
  • Day 4 Furosemide 400mg / day infused with 100cc of Hartmann solution

Group B: Furosemide 80 mg every 24 hrs (morning) intravenously every 24 hrs for 4 consecutive days, additionally:

  • Day 1 furosemide 100mg / day infused with 100cc of Hartmann solution + Chlortalidone 50mg VO every 24 hours + Spironolactone 50mg VO every 24 hrs.
  • Day 2 furosemide 100mg / day infused with 100cc of Hartmann solution + Chlortalidone 50mg VO every 24 hours + Spironolactone 50mg VO every 24 hrs.
  • Day 3 furosemide 100mg / day infused with 100cc of Hartmann solution + Chlortalidone 50mg VO every 24 hours + Spironolactone 50mg VO every 24 hrs.
  • Day 4 furosemide 100mg / day infused with 100cc of Hartmann solution + Chlortalidone 50mg VO every 24 hours + Spironolactone 50mg VO every 24 hrs.

ution + Chlortalidone 50mg VO every 24 hours + Spironolactone 25mg VO every 24 hrs.

With the primary objective of improving renal function measured by serum creatinine, as secondary objectives the efficacy in vascular decongestion and electrolyte alterations.
