Routine use of color Doppler in fetal heart scanning in a low-risk population.

Objectives. To investigate the detection rate of major fetal heart defects in a low-risk population implementing routine use of color Doppler. Material and Methods.

Oxygen saturation in healthy newborns; influence of birth weight and mode of delivery.

Aims: To study the normal levels of oxygen saturation (SpO(2)) in healthy newborns during the first 24 h of life and the possible relationship to birth weight and mode of delivery.

Methods: SpO(2) was measured by pulse oximetry on one occasion between 2 and 24 h after birth in 6805 asymptomatic newborns with gestational age > or =34 weeks and birth weight > or =2500 g.

Results: The average SpO(2) for all children was 98.
