Natriuresis-guided Depletion After Cardiac Surgery

"Furosemide IV, 20 mg starting dose, titrated every 6 hours based on urinary sodium measured by the LAQUAtwin NA-11 device.~Urine output will be measured and recorded every 4 hours to ensure accurate diuresis tracking.~If natriuresis is \< 70 mmol/L, the furosemide dose will be doubled, with a maximum limit of 200 mg per bolus.~If natriuresis is ≥ 70 mmol/L, the current dose will be maintained.~Blood electrolyte panels and renal function assessments will be performed twice daily throughout the protocol.~In the event of hemodynamic instability, a complete echocardiographic assessment will be performed for all patients to detect potential surgical complications, along with a hemodynamic evaluation to guide appropriate management."

"Furosemide IV, 20 mg starting dose, titrated every 6 hours clinical evaluation.~Urine output will be measured and recorded every 4 hours to ensure accurate diuresis tracking.~The furosemide dosage will be adjusted based on urine output with a maximum bolus dose of 200 mg. Dose adjustments will be reassessed every 6 hours throughout the study period.~Blood electrolyte panels and renal function assessments will be performed twice daily throughout the protocol.~In the event of hemodynamic instability, a complete echocardiographic assessment will be performed for all patients to detect potential surgical complications, along with a hemodynamic evaluation to guide appropriate management."
