fetal heart rate monitoring
Continuous assessment of fetal cardiac activity during surgery to detect compromise and guide intervention.
Full Definition
Fetal heart rate monitoring involves continuous electronic surveillance of fetal cardiac activity throughout surgical procedures to detect signs of fetal compromise, hypoxia, or distress. In fetal surgery, monitoring may be accomplished via external Doppler, fetal ECG electrodes, or pulse oximetry depending on surgical access and fetal positioning. Specific patterns such as bradycardia, tachycardia, or loss of variability trigger immediate evaluation and potential intervention. The technology and interpretation differ significantly from routine obstetric monitoring due to anesthetic effects and surgical manipulation.
Usage
Usage note: Specify monitoring method and any technical limitations in operative reports.
In Context
- "Continuous fetal heart rate monitoring showed reassuring patterns throughout the 90-minute procedure." — Intraoperative record
- "Loss of fetal heart rate monitoring signal necessitated conversion to direct fetal ECG placement." — Technical complication note
