| Popis: | We tested the hypotheses that fetal heart rate decelerations are present during the third trimester in most low risk pregnant women, the prevalence of decelerations is a function of the length of time fetal heart rate monitoring occurs and their presence is not associated with an adverse prognosis. We performed a retrospective chart review of 114 self-referred low-risk pregnant patients who presented to the labor and delivery triage area of a tertiary care hospital at 26-41 weeks gestation. None required admission to the hospital. The control group consisted of patients who delivered immediately before and after the delivery of the study patient. Normal long-term variability and fetal baseline heart rate were found in all electronic fetal monitoring tracings. Accelerations were present in 91% and decelerations in 65% of patients. There was no correlation between length of time of monitoring and the incidence of decelerations. At delivery, there were no differences in birthweight, gestational age, 5-min Apgar scores or cord pH between the control and study patients. Variable decelerations were a common finding in the third trimester of low-risk pregnant patients who self referred to labor and delivery triage. They were not prognostic of an adverse perinatal outcome. |
