Good prognosis for psychomotor development in survivors with nonimmune hydrops fetalis.

We examined the psychomotor development of 33 of 61 surviving children, from a series of 107 consecutive live-born cases with nonimmune hydrops fetalis. The majority had a normal outcome. Three had a (simultaneous) serious underlying disease (e.g. fetal herpes infection) and had either severe psychomotor retardation or blindness. Two showed clumsiness and were considered to have minor neurological dysfunction. We conclude that survivors, especially those with transient benign intrauterine conditions, such as lymphatic aetiology have no additional risk to their psychomotor development.
