• Brady cardia
• Altered fetal tone
.Absent fetal respiration
Answer: Bradycardia?
Fetal Monitoring
Monitoring consists of measuring uterine contractions with a tocometer, fetal HR with a Doppler transducer, and fetal movement and tone with ultrasonography. Together, these measurements yield a good indication of fetal health. Preoperative ultrasonography can also approximate gestational age when an accurate history cannot be obtained. Gestational age plays a pivotal role in all surgical decision making for a pregnant patient.
The fetal HR is routinely measured both preoperatively and postoperatively. Though the fetal HR can be heard 14 weeks after conception, it serves as an indicator of fetal oxygenation only after week 26. Specific fetal HR abnormalities—absence of variability, late or variable decelerations, and bradycardia—are predictive of impending fetal hypoxia, physical damage, or death. In the absence of these extreme (and hence obvious) fetalHR patterns, interpretation of fetal tracings can be complex. There are no conclusive data to suggest that any single monitoring technique reflects fetal outcome.Optimization of maternal physiologic status is more important than any mode of fetal monitoring.
