Multimodal Uterotonics at the Time of Cesarean Section in Laboring Patients
A Randomized Controlled Trial to Assess the Effectiveness of Multimodal Prophylactic Uterotonics in Patients Undergoing Non-Elective Cesarean Sections After a Trial of Labor
Postpartum hemorrhage remains a leading cause of maternal morbidity and mortality worldwide, even in high income countries. Uterine atony is estimated to cause 70-80% of postpartum hemorrhage. Prolonged labor and augmented labor are known risk factors for postpartum hemorrhage. In attempts to reduce the incidence of postpartum hemorrhage, particularly in patients with known risks factors, it is essential to optimize preventative practices in order to reduce the rates postpartum hemorrhage.
Although oxytocin is considered the first line therapy for preventing and treating uterine atony, early consideration of additional prophylactic uterotonic agents may be indicated in women with prior oxytocin exposure given oxytocin receptor desensitization and down regulation.
As such, investigators sought to examine whether multimodal prophylactic uterotonics (standard oxytocin + methylergonovine), in patients who are increased risk of developing postpartum hemorrhage (specifically laboring patients who ultimately require a cesarean section) would benefit from the addition of prophylactic uterotonics. The clinical rational for administration of multimodal prophylactic uterotonics at the time of cesarean delivery in laboring patients is three-fold: to decrease the incidence of uterine atony, to decrease the incidence of postpartum hemorrhage, decrease the number of uterotonics required at the time of cesarean section.
The primary outcome will be to evaluate the need for additional uterotonic agents (Methylergonovine, Carboprost, Misoprostol) at the time of delivery.
Secondary outcomes will include the incidence of postpartum hemorrhage (quantitative blood loss >1 liter), surgical assessment of uterine tone four minutes following delivery of the placenta, preoperative and postoperative hemoglobin, the need for a blood transfusion, intensive care unit admission, uterine infection (endometritis).

Detailed Description
All patients who meet eligibility for the study will be consented during their clinic visit or upon arrival to labor and delivery. If patients elect to participate in the study, enrollment in the study will be noted in their sticky note in EPIC (electronic medical record) which will be ready available to all members of the health care team. If patients during the labor process require a cesarean section, the anesthesiologist will pick up a sealed envelope (which will contain the allocation sequence and group assignment). A randomization block design with mixed block sizes will be used to generate the allocation sequence by using the nQuery Advisor computer software.
The sealed envelopes will be readily available to the anesthesiologist and kept in the anesthesia workroom. Following delivery of the infant, the patient will receive the standard oxytocin infusion. Following administration of the oxytocin infusion, the patient will be given either methylergonovine 0.2 mg IM (intramuscular) or placebo (1 ml of normal saline, intramuscular). This will be drawn up and administered by the anesthesiologist. The obstetrician (delivering provider performing the cesarean section) will be blinded to the group assignment. Documentation of the drug will be recorded in epic in the medication administration record.
The delivering provider will be responsible for determining and relaying to the anesthesiologist whether additional uterotonics are needed throughout the procedure. Additional uterotonics will be given in accordance to the current guidelines outlined by the American Congress of Obstetricians and Gynecologists (ACOG). The delivery provider will assess uterine tone at 4 minutes (satisfactory versus unsatisfactory). The registered nurse will be responsible for setting up a timer to let the OB provider know when 4 minutes have passed. Nursing will call out once the 4 minutes have passed and the OB provider will state whether adequate tone was noted. The anesthesiologist will be responsible for documenting whether a placebo/study drug was given and uterine tone after 4 minutes. This documentation will be placed back into the sealed envelope by the anesthesiologist and placed in the anesthesia workroom. Nicole Masse (primary investigator) will be responsible for storing folders in a secured, locked file cabinet within the Maternal Fetal Medicine offices.
As routinely done at the time of cesarean delivery, the registered nurse will be responsible for measuring and documenting the quantitative blood loss. As routinely performed on all are patients who undergo a vaginal or cesarean delivery, preoperative hemoglobin and postoperative day one hemoglobin levels will be collected.
In the event a postpartum hemorrhage was to occur, the obstetrician will then be un-blinded as management of a postpartum hemorrhage will be driven by whether normal saline or methergine was given as part of the study.
The primary outcome, the need for additional uterotonics, will be assessed in the operating room. Other outcome which will be assessed in the operating room include uterine tone and quantitative blood loss. Outcomes which will be assessed in the immediate postpartum period include: postpartum hemoglobin values, need for a blood transfusion, admission to the intensive care unit, endometritis).
No long-term follow will be needed.

Quantitative Blood Loss
Time Frame: Quantitative Blood Loss is measured at the completion of the cesarean delivery, an average of 2 hours
|
As per protocol, nurses will measure the quantitative blood loss by measuring the blood in the canisters used during the cesarean section and by weighing the sponges used in the surgery.

|
As per standard protocol, preoperative and postoperative day one hemoglobin levels will be evaluated.
