Active Comparator
Experimental
A: Hydratation according LVEDP + NaHCO3
B: Standard hydratation
C: Hydratation with sodium bicarbonate
Hydration with bolus of NaCl 0.9 to reach a LVEDP of 18 mmHg or more. This procedure is done while the patient is in the laboratory, with a catheter in the left ventricle. At the same time, an infusion of a sodium bicarbonate solution (150 mEq/L) is started at a rate of 1 ml/kg/h (max 110 ml/h) for 7 hours.
hydratation with normal saline (1 cc/kg/h; max 110 cc/h) starting at 8PM the day before the test and ending at 8PM the day of the test (24 hours total).
hydratation with sodium bicarbonate (150 mEq/L) at 3 cc/kg/h (max 330 cc/h) for 1 hour before the test and then, to be continued at 1 cc/kg/h (max 110 cc/h) for 6 hours (total of 7 hours of hydratation).
