Abstract:
:A total of 679 fetal monitoring records were carefully reviewed in order to determine the incidence of occurrence of late and variable deceleration patterns with respect to advancing gestational age. No statistically significant increase in occurrence of these patterns could be detected in gestations that progressed beyond 42 weeks. The previously held concept that routine prophylactic intervention in gestations of 42 weeks or more must be challenged.
