para prevenir el alto riesgo que existe de que se produzca un parto
prematuro. Las madres presentan un riesgo aumentado de edema
pulmonar en el período postoperatorio como resultado de la agre-
sividad del tratamiento tocolítico; por tanto, se recomienda la vigi-
lancia estrecha del balance hídrico.
