The serotonin type 3 receptor antagonist BRL 43694 and nausea and vomiting induced by cisplatin.

ment was not successful, and possibly a longer duration of transplacental treatment would have been more appropriate. In our series the Wolff-Parkinson-White syndrome as the underlying cause of the tachycardia was found in three of the 22 infants who had a postnatal electrocardiogram. In summary p, ,hological atrial tachycardias are a potential cause of non-immune hydrops. As these rhythm disturbances may be intermittent, this diagnosis should be considered in all cases of fetal hydrops even if the tachycardia is not present at the initial examination. It is not possible to predict which of the non-hydropic fetuses will progress to become hydropic. We therefore believe that an attempt at transplacental treatment is valid in all cases. Our results show that maternal transplacental treatment is both safe and effective and may avert preterm delivery and its attendant morbidity.
