Brief Summary:
This is a pilot double-blinded placebo-controlled randomized controlled trial (RCT) to evaluate the feasibility of conducting a multicenter, randomized, placebo-controlled trial to assess the efficacy of pre-transfusion furosemide in preventing transfusion-associated circulatory overload (TACO) in hemodynamically stable inpatients aged 65 years or older receiving a single unit red blood cell transfusion. Patients will be randomly allocated to receive either furosemide (20mg intravenous) or placebo (saline) within 60 minutes of starting a red blood cell (RBC) transfusion. Randomization will be stratified by centre and renal dysfunction (creatinine clearance ≥ 60 mL/min or < 60 mL/min). This is a blinded trial: patients, care-providers (physicians and nurses), data collectors, outcome adjudicators, and data analysts will not be aware of group allocation.

Drug Information available for: Furosemide

Arm Intervention/treatment
Experimental: Furosemide
Drug: Furosemide
A bolus dose of 20mg furosemide (20mg/2mL) will be given intravenously by slow intravenous push within 60 minutes prior to the start of the red blood cell transfusion; infusion via minibag is also acceptable.
Other Name: Lasix

Placebo Comparator: Placebo
Normal saline
Drug: Normal Saline
A single bolus dose of 2 mL normal saline will be given intravenously immediately within 60 minutes prior to the start of the red blood cell transfusion; infusion via minibag is also acceptable.
Other Name: 0.9% Sodium Chloride

  9. Incidence of TACO within 6 hours from completion of transfusion [ Time Frame: within 6 hours ]
  10. Severity of TACO-graded as per the Public Health Agency of Canada's Transfusion Transmitted Injuries Surveillance System [ Time Frame: within 6 hours ]
  11. Validation of TACO as per criteria adopted from the US Center for Disease Control [ Time Frame: within 6 hours ]
  12. Change in plasma brain natriuretic peptide(BNP) [ Time Frame: Baseline and Day 1 ]
  13. Net fluid balance at 24 hours from start of transfusion- all intravenously-administered fluids (including the transfused blood product and the study intervention) [ Time Frame: Within 24 hours ]
  14. Proportion of patients developing hyponatremia or hypokalemia by Day 1 [ Time Frame: By Day 1 ]
  15. Proportion of patients developing hypotension [ Time Frame: Within 24 hours ]
  16. Proportion of patients developing acute kidney injury [ Time Frame: Within 24 hours ]
  17. Need for increased supplemental oxygen is defined as any increase in oxygen flow ≥ 1 L/hr or (fraction of inspired oxygen)FiO2 ≥ 5% of 1 hour duration or longer, prompted by either patient symptoms or a fall in oxygen saturation(SpO2) ≥ 5% [ Time Frame: Within 24 hours ]
  18. Need for inotropic support is defined as the initiation of a continuous infusion of dopamine, dobutamine, epinephrine, or norepinephrine [ Time Frame: Within 24 hours ]
  19. Need for additional diuretic or vasodilatory therapy is defined by the prescription of non-study furosemide, hydrochlorothiazide, metolazone, or either transdermal or intravenous nitroglycerin [ Time Frame: Within 24 hours ]
  20. Occurrence of acute coronary syndrome or new arrhythmia [ Time Frame: within 7 days ]
  21. Mortality during hospital stay [ Time Frame: Upto 30 days ]
  22. Length of hospital stay [ Time Frame: From date of admission until the date discharge from an acute care hospital or date of death from any cause, whichever came first, assessed up to 30 days. ]
