Overview
Brief Summary
The goal of this study is to determine whether the use of sequential compression devices (lower limb compression) can reduce the rate of maternal hypotension after epidural, and therefore reduce the incidence of fetal heart tracing complications during labor.
Detailed Description
Maternal hypotension during epidural anesthesia in laboring patients can cause a number of problems for both mother and fetus. Despite standard anesthesia protocols designed to minimize the occurrence of hypotension during epidural placement, approximately 30% of laboring patients will still experience clinically significant hypotension. Maternal hypotension can affect placental blood flow causing fetal bradycardia and academia, as well as maternal symptoms such as dizziness, nausea, and vomiting. Therefore, there is a need for improved management of women in labor at time of epidural placement to avoid negative consequences for mother and fetus. We plan to investigate whether the use of lower limb compression devices at the time of epidural would decrease maternal hypotension. Pregnant women who request epidural anesthesia during labor will be recruited and enrolled in this single site, randomized controlled trial. Patients will be randomized into either control or sequential compression device (SCD) groups. Following epidural, blood pressures will be measured at 1, 5, 15, 30, 45, and 60 minutes and rates of hypotension with subsequent fetal heart tracing abnormalities will be recorded.
