A randomized controlled trial of third-trimester routine ultrasound in a non-selected population.

Objective: To compare detection rates of small-for-gestational-age fetuses, large-for-gestational-age fetuses, congenital anomalies and adverse perinatal outcomes in pregnancies randomized to third-trimester routine ultrasound or ultrasound on clinical indication.

Design: Randomized controlled trial.

Setting: National Center for Fetal Medicine in Norway between 1989 and 1992.

Obstetric brachial plexus palsy: a birth injury not explained by the known risk factors.

Objective: To determine the incidence and prognosis of obstetric brachial plexus injuries and analyze associated risk factors.

Design: Analysis of prospectively collected information comprising all births from 1991 to 2000, with complete follow-up of affected children. Setting.

First day of life pulse oximetry screening to detect congenital heart defects.

Objective: To evaluate the efficacy of first day of life pulse oximetry screening to detect congenital heart defects (CHDs).

Study Design: We performed a population-based prospective multicenter study of postductal (foot) arterial oxygen saturation (SpO(2)) in apparently healthy newborns after transfer from the delivery suite to the nursery. SpO(2) < 95% led to further diagnostic evaluations.

Induction of labor or serial antenatal fetal monitoring in postterm pregnancy: a randomized controlled trial.

Objective: To compare induction of labor at gestational age 41 weeks with expectant management in regard to neonatal morbidity. Secondary aims were to assess the effect of these managements on mode of delivery and maternal complications.

Methods: Between September 2002 and July 2004, postterm women with singleton cephalic presentation and no prelabor rupture of membranes were randomly assigned to induction of labor at 289 days or antenatal fetal surveillance every third day until spontaneous labor.

[Vertical transmission of hepatitis C virus in Sor-Trondelag].

Background: The aim of this study was to investigate the vertical transmission rate of hepatitis C virus (HCV) in a Norwegian county and describe the clinical outcome of the infected infants.

Material And Methods: Over the 1991-2000 period, 29,433 pregnant women gave birth to 37,893 children. Women born in high endemic areas and those with a history of drug abuse were offered anti-HCV testing.
