High-risk pregnancy. Identification and monitoring to improve outcome.

High-risk pregnancy is a problem that directly affects both the patient and the physician. Technological advances have provided improved methods of monitoring the fetus, especially through ultrasonography and electronic fetal heart rate monitoring. However, it is still up to the physician to identify the pregnancy at risk and to properly interpret the information obtained by monitoring. To date, expert clinical management still offers the best hope for a good obstetric outcome.
