0358: Diuretic treatment versus fluid expansion in acute normotensive pulmonary embolism - 12/02/16
Résumé |
Background |
In submassive pulmonary embolism (PE), when a right ventricular (RV) dysfunction (RVD) is present, the benefit of fluid expansion (FE) is questionable. The Franck-Starling law suggests that the reduction of the RV overload may enhances the RV systolic function.
Purpose |
The aim of our study was to compare the effects of a diuretic treatment (DT) versus FE in patients hospitalized for normotensive PE with RVD.
Methods |
We performed a prospective study. Consecutive patients hospitalized for normotensive PE were treated with diuretic (40mg IV furosemide at admission) or FE (500cc of sodium chloride infusion during four hours at admission). The primary endpoint was the timing for normalization of BNP and troponin Ic values. The secondary endpoints were variations of clinical and RV echographic parameters.
Results |
Forty five patients were included. Timing for Troponin and BNP normalization was 60,7±28 hours in the DT versus 93,2±42 hours in the FE group (figure 1, p=0.02). Normalization of RV dilatation took 91,7±14,2 hours in the DT group versus 108,4±17,5 hours in the FE group (p=0.01). Normalization of the RVD took 81,2±18 hours in the DT group versus 94,9±13,1 hours in the FE group (p=0.03).
Conclusion |
In the early management of normotensive PE with RVD, DT may be superior to FE in order to improve the time to normalization of biological and echocardiographic markers.
