Perioperative assessment of fetal heart rate and uterine activity.

Improvements in surgical techniques and anesthesia allow women the option to schedule needed surgery during pregnancy. However, perioperative monitoring of the fetus and uterine activity remains a matter of controversy. Monitoring may allow rapid improvement of the fetal status or uterine activity when early compromise or contractions are detected. The reassurance and decreased medicolegal risks provided by perioperative monitoring may offset the cost of a perinatal nurse and use of monitoring equipment even though the drug and anesthetic effect on the fetal heart limit the benefits of monitoring. Simply providing adequate maternal respiratory support during surgery may improve the fetal pattern but will not eliminate external surgical effects. The need for additional research is described, and the role of the perinatal nurse is detailed in a suggested protocol.
