A very rare case of a sustained fetal ventricular arrythmia in the form of bigeminy, trigeminy, and quadrigeminy during labor is described. The rhythm disturbance failed to respond to sedatives and narcotics but was successfully reverted to sinus rhythm following the administration of intravenous propranolol to the mother. The significance and possible mechanism of the arrhythmia is discussed.

The hazards of amniocentesis for intrauterine diagnosis have yet to be established. We are particularly concerned by the high incidence (7.5 per cent) of postamniocentesis abortions and amniotic fluid leaks in our series. A larger experience is certainly needed before these concerns can be disregarded. Until then, it is important that indications for this procedure be strictly adhered to.

This case report describes the antenatal diagnosis of a fetal pulmonary anomaly. Early detection afforded detailed parental counseling and prompt neonatal diagnosis and treatment.

At a time when the intrauterine diagnosis of hydrocephalus is common and pioneering efforts of antenatal therapy are evolving, an assessment of intrauterine treatment of this disorder becomes pertinent. Consequently, the current status of the intrauterine treatment of fetal hydrocephalus is presented. The new data from the International Fetal Surgery Registry at the University of Manitoba in Winnipeg are discussed. The technical problems of antenatal shunting, the clinical trials, and experimental treatment are assessed. The prognostication and possible new approaches in intrauterine treatment of hydrocephalus are presented as well as the new diagnostic and surgical techniques. The outcome of the antenatal diagnosis and treatment of fetal hydrocephalus is evaluated.
