OBJECTIVE: To identify specific estimates and predictors of neonatal morbidity and mortality in early onset fetal growth restriction due to placental dysfunction. METHODS: Prospective multicenter study of prenataly diagnosed growth-restricted liveborn neonates of less than 33 weeks of gestational age. Relationships between perinatal variables (arterial and venous Dopplers, gestational age, birth weight, acid-base status, and Apgar scores) and major neonatal complications, neonatal death, and intact survival were analyzed by logistic regression. Predictive cutoffs were determined by receiver operating characteristic curves. RESULTS: Major morbidity occurred in 35.9% of 604 neonates: bronchopulmonary dysplasia in 23.2% (n=140), intraventricular hemorrhage in 15.2% (n=92), and necrotizing enterocolitis in 12.4% (n=75). Total mortality was 21.5 % (n=130), and 58.3% survived without complication (n=352). From 24 to 32 weeks, major morbidity declined (56.6% to 10.5%), coinciding with survival that exceeded 50% after 26 weeks. Gestational age was the most significant determinant (P<.005) of total survival until 266/7 weeks (r2=0.27), and intact survival until 292/7 weeks (r2=0.42). Beyond these gestational-age cutoffs, and above birth weight of 600 g, ductus venosus Doppler and cord artery pH predicted neonatal mortality (P<.001, r2=0.38), and ductus venosus Doppler alone predicted intact survival (P<.001, r2=0.34). CONCLUSION: This study provides neonatal outcomes specific for early-onset placenta-based fetal growth restriction quantifying the impact of gestational age, birth weight, and fetal cardiovascular parameters. Early gestational age and birth weight are the primary quantifying parameters. Beyond these thresholds, ductus venosus Doppler parameters emerge as the primary cardiovascular factor in predicting neonatal outcome. LEVEL OF EVIDENCE: II

The incidence of obstetric brachial plexus injury (OBPI) was investigated and the natural course of this disorder and the frequency of shoulder contracture described. Between 1988 and 1997 13 366 children with a gestational age of 30 weeks or more, were born at the Academic Medical Center, Amsterdam. Of these, 62 had an OBPI (4.6 per 1000). Complete neurological recovery occurred in 72.6% of cases. Half of them had a delayed recovery of more than three weeks (mean recovery time 6.2 ± 3.1 months). Shoulder contracture occurred in at least one-third of the children with delayed recovery and in at least two-thirds of the children with incomplete recovery. The incidence of OBPI in our hospital was found to be higher and to have a less favourable natural course than is usually reported in the literature. Contracture of the shoulder joint is frequently found even in infants with complete neurological recovery.
