Abstract P-257

Aims & Objectives: Hydric overload is associated with worse outcomes in Pediatric Intensive Care Unit (PICU). Among the alternatives for the hydric balance to be optimized, the establishment of the prone position is found as such. To verify if the prone position in pediatric patients submitted to mechanical ventilation increases diuresis with optimization in the outcomes. Methods Retrospective cohort through review of medical records. It was selected patients who were submitted to ventilation for pulmonary causes and aged from 1 month old to 12 years old. The prone group (PG) was the one in which the patients were submitted to the prone position at some point of the study The control group (CG) was the one in which the patients met the inclusion criteria but were not undergone prone position. Results 77 patients were included (PG=37 and CG=40). There was no significant improvement of diuresis, hydric balance, mechanical ventilation and hospitalization duration in the PICU. Regarding the use of diuretics, there was greater use of furosemide (P<0.001) and spironolactone (P=0.04) in the PG. When performed a longitudinal analysis of repeated measures of D1 to D4, it was shown that both PG and CG had improved diuresis and hydric balance, with a more significant improvement from D1 to D2 in the PG (P=0.034). Conclusions There was improvement of both diuresis and hydric balance of patients in both groups, without showing, however, superiority of the prone group in relation to the control group.
