title: The influence of ultrasound on the frequency of amniocentesis.
abstract: To determine the effect of development of ultrasonographic guidance techniques on the frequency of amniocentesis, we compared two two-year periods before and after the use of ultrasound. Statistically significant decreases in both the number of amniocenteses ordered and the number performed were observed. We concluded that ultrasound has been judiciously used and has not prompted an increased use of amniocentesis merely because of improved ease and safety. A slight decrease in the perinatal mortality rate mitigates against any compromise in the standard of antenatal care.
