Laboring Subjects
Subjects with a planned cesarean delivery who labor prior to their scheduled date or those who are in labor and require an unplanned but non-emergent cesarean delivery.
These subjects will be approached upon admission to the study facility by the researcher for potential enrollment to allow adequate time to consider participation, ask questions, provide consent, and prior to procedure (Myometrial Sampling).
|
A myometrial sample will be obtained at the time of cesarean delivery. Sample will be obtained from the superior edge of the existing lower uterine segment incision and will be 2 inches in length and 0.5 inches in width. The uterine incision will be repaired in a standard two-layer closure. If a classical cesarean (vertical) uterine incision is deemed necessary and is performed by the surgical team, a sample of the same size will be taken parallel to the incision at the existing edge. The classical uterine incision will be closed utilizing the standard layered technique. Placenta and gestational membrane tissue will be obtained after placental delivery. The entire placenta and attached gestational membranes will be collected if not being sent for pathologic review |
Non Laboring Subjects
Subjects with a planned cesarean delivery will be approached by the researcher during prenatal visits or at the study facilities prior to planned procedure (Myometrial Sampling)
