The most prevalent clinical manifestation of abruptio placentae (as opposed to placenta previa) is:

Epidural blocks are commonly used during labor to provide pain relief. However, they can also cause a sudden drop in blood pressure, known as epidural-induced hypotension, which can affect fetal oxygenation and fetal heart rate. Therefore, it is important to monitor maternal blood pressure frequently after an epidural block is administered.

While monitoring the maternal pulse is also important, hypotension is the most common complication of epidural anesthesia and can lead to decreased blood flow to the fetus. Therefore, monitoring maternal blood pressure is the priority.

Monitoring the fetus is also important, but it is not the most important intervention after an epidural block. Limiting parenteral fluids may be necessary in some cases to help prevent or treat hypotension, but it is not always necessary and should be done based on the individual situation.

Fetal well-being during labor is assessed by the response of the fetal heart rate (FHR) to uterine contractions (UCs). During labor, the fetal heart rate is monitored to assess the well-being of the fetus. The fetal heart rate should increase in response to fetal movement and contractions, which indicates that the fetus is receiving adequate oxygenation and blood flow. This response is called an "acceleration" in the FHR. However, accelerations alone are not enough to assess fetal well-being during labor. It is the combination of the FHR pattern with the uterine contractions pattern that provides the most information.

In addition to the FHR response to UCs, other factors that may be used to assess fetal well-being during labor include fetal scalp blood sampling, fetal pulse oximetry, and fetal ultrasound. Maternal pain control may help to decrease maternal stress and anxiety during labor, but it is not directly related to fetal well-being. An FHR above 110 beats/min is within the normal range for a fetal baseline heart rate, but it is not enough to assess fetal well-being during labor.
