Physiologic and Biochemical Effects of Ritodrine Therapy on the Mother and Perinate
ABSTRACT
The materno-fetal and neonatal effects of ritodrine were studied in 37 women treated for premature labor with intravenous (i.v.) ritodrine. Marked cardiovascular, respiratory, and biochemical side effects of therapy were seen in the mothers and tachycardia was noted in the fetuses. The neonates of 18 women in whom ritodrine successfully postponed delivery were delivered with good Apgar scores and their admission vital signs and nursery courses were benign. Ritodrine failed to delay delivery more than a week in 19 mothers. There were no differences between their newborns and 20 control neonates in admission vital signs, blood gases, blood chemistries, complete blood counts, platelet counts, peak bilirubin, or duration of oxygen therapy. This study revealed no deleterious effects on neonates delivered after maternal ritodrine therapy despite significant maternal and fetal effects

Intrauterine Positional Deformations Masquerading as Multiple Congenital Malformations
• A 1,340-g male neonate was delivered by emergency cesarean section at 28 weeks' gestation following failed therapy with isoxsuprine hydrochloride and fetal distress. Transverse-lie presentation with the posterior side of the thorax wedged into the maternal pelvis and the head flexed firmly against the anterior side of the thorax led to a severe deformation sequence initially interpreted as multiple congenital malformations. This case illustrates the difficulty in distinguishing between pure deformations and malformations with and without subsequent deformations. It also emphasizes the clinician's need for a definitive diagnosis to guide the management of suspected malformations that are potentially lethal or portend a poor neurodevelopmental outcome.(AJDC 1984;138:642-644

Etiologic heterogeneity in the oculoauriculovertebral syndrome
Platelet dysfunction and coagulopathy in intraventricular hemorrhage in the premature infant
We investigated platelet count, bleeding time, platelet aggregation, prothrombin time, activated partial thromboplastin time, and fibrinogen level in 58 very low-birth-weight infants during the first postnatal day to determine the relationship between hemostatic disorders and intraventricular hemorrhage. Thirty-two of the 58 infants (55%) were found to have periventricular-intraventricular hemorrhage by computerized tomography or autopsy. Nine patients (16%) had subarachnoid hemorrhage only and 17 (29%) had no evidence of intracranial hemorrhage. Infants with IVH had a significantly lower mean platelet count than did infants with no SAH/IVH. However, only five patients with IVH had initial thrombocytopenia. The IVH group had a mean bleeding time which was significantly prolonged compared to that of the group without SAH/IVH. Similarly, patients with IVH had a mean platelet aggregation response which was significantly diminished in comparison to that of patients with no SAH/IVH. Infants with IVH had a significantly longer mean PT than did infants with no SAH/IVH. In addition, babies with IVH had a significantly longer mean APTT compared to that of babies without SAH/IVH. The groups did not differ significantly with respect to fibrinogen levels. Three infants with IVH had disseminated-intravascular coagulation in the early neonatal period. These data suggest that disorders of platelet-capillary interaction and defects in the intrinsic and extrinsic coagulation pathways may play important roles in intraventricular hemorrhage in the premature infant
