Nonimmunologic hydrops fetalis: a review of 11 cases.

Eleven cases of nonimmunologic hydrops fetalis occurring during a six year period were reviewed. The etiology of hydrops fetalis was established only in four cases. It included one case of endocardial fibrosis, two cases of non-immunologic hemolysis and one case of tachycardia. The pregnancies were complicated by polyhydramnios in 9 cases, preterm delivery in 10 cases, twins in 3 cases and pre-eclampsia in one case. Four of 11 fetuses died in utero, on one of them, intrauterine blood transfusion and administration of digoxin and furosemide was carried out. Five fetuses died neonatally and two survived. In one of the later cases, intravenous administration of digoxin with quinidine to the mother was without effect, nor did such treatment cause any effect on the neonate after delivery. Electric cardioversion supplemented with digoxin slowed the neonatal cardiac rhythm to normal range with later successful outcome. Earlier diagnosis by ultrasonography especially in cases of hydramnios and appropriate treatment are likely to improve this outcome.
