What is meant by the "at risk" pregnancy?

Monitoring to detect the "at risk" foetus has advanced dramatically in the last decade; clinical as well as more sophisticated methods have been discussed. Some of these are well within the scope of the general practitioner who has undergone further training in obstetrics. If all practitioners are aware of these advances, ready consultation for the continued monitoring of the foetus at risk will decrease the avoidable perinatal loss and quality of the neonate, which at the present time is showing virtually no improvement.
