Managing nonreassuring fetal heart rate patterns before cesarean delivery. Compliance with ACOG recommendations.

Objective: To determine the rate of compliance with current American College of Obstetricians and Gynecologists (ACOG) recommendations for management of parturients undergoing cesarean delivery for persistent nonreassuring fetal heart rate (FHR) tracings.

Study Design: We performed a retrospective chart review (July 1995-June 1998) of all parturients who underwent cesarean delivery for nonreassuring FHR tracings. Outcome measures included maneuvers for fetal assessment (scalp stimulation or scalp blood pH) and therapeutic interventions (tocolytic agents for reducing uterine activity or amnioinfusion).

Validation of bioimpedance estimates of cardiac output in preeclampsia.

Objective: We sought to evaluate the capacity of a new thoracic electric bioimpedance system to estimate cardiac output in patients with preeclampsia.

Study Design: We performed a prospective comparison of thoracic electric bioimpedance and echocardiographic M-mode volumetric estimates of cardiac output (in liters per minute) in preeclampsia. Subjects with preeclampsia who were chosen by means of strict criteria (either a systolic blood pressure >/=140 mm Hg or a diastolic blood pressure 90 mm Hg, or both, and proteinuria >/=300 mg in 24 hours or >/=+1 on repeat dipstick measurement 6 hours apart) were asked to participate in an institutional review board-approved study.

Intrapartum care for women with multiple pregnancy.

Intrapartum management of multiple pregnancy presents many challenges for obstetric nurses. Optimal care often is complicated by prematurity, low and very low birth weights, and the unique circumstances of the delivery of multiple neonates. Higher perinatal mortality for multiple pregnancies continues to complicate delivery outcome.

Prenatal care and multiple pregnancy.

Prenatal care of multiple pregnancy presents a variety of nursing challenges. Specialized care, beginning in early pregnancy, can have a significant impact on the outcome for mothers and neonates. Dramatically increasing roles for advanced technology in the care of multifetal pregnancies must be balanced with families' needs for education and support.

Correlation of antepartum uterine activity and cervical change in twin gestation.

Objective: To determine the correlation between quantitative measurements of antepartum uterine activity and cervical change twin gestations.

Methods: Forty women from our Twin Clinic constituted the study group. Participants had a cervical examination each week between 20 and 37 weeks gestation and a cervical score (CS) was calculated as follows: CS = cervical length (cms)-cervical dilation (cms) at the internal os.
