Filter by:From patient charts we will review patients who had undergone cesarean section within the last 6 months and identify those who received a The Hayman uterine compression suture for uterine atony. We will also select patients who delivered a baby without recieving a Hayman suture to create a control group. Patietns will be grouped as Hayman Group if they recevied a Hayman suture during C/S and control group if thay had not recevied a Hayman suture. We will then check patient charts for post-cesarean outpatient clinic visit and select those who received ovarian reserve evaluation via hormones and antral follicle count during the visits. Finally, we are planning to investigate any correlation between Hayman suture and ovarian dysfunction.
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).
In this pilot study, investigators will administer calcium chloride or placebo to pregnant women undergoing Cesarean delivery who have been identified as high risk for hemorrhage due to poor uterine muscle contraction, or atony. They will assess whether a single dose of calcium given immediately after the delivery of the fetus decreases the incidence of uterine atony and bleeding for the mother. The pharmacokinetics of calcium chloride in pregnant women will also be established. Data from this pilot study of 40 patients will be used to determine sample size and appropriateness of a larger randomized clinical trial.
Study aim to evaluate the efficacy and safety of a novel technique of UTERINE COOLING during repeated cesarean section (CS) in reducing blood loss, and record any adverse effects following it.
The aim of this study is to evaluate in a randomized fashion the comparative efficacy of two second-line medications, methylergonovine and carboprost for treating atonic postpartum hemorrhage (PPH). The investigators hypothesize that administration of methylergonovine will produce superior uterine tone to carboprost in atonic PPH.
The primary objective of this study is to determine whether there are markers in the tissue of atonic uteri, and in the patients' plasma that would help identify patients likely to suffer postpartum hemorrhage due to uterine atony. We also will attempt to identify the cause(s) of uterine atony that might suggest mechanisms to prevent and manage it.
Patient's with planned cesarean sections will be randomized to receive either standard 20 mU in 1L as a bolus following delivery of the placenta or 20 mu in 1L following delivery of the placenta plus an additional 20 mU in 1L over 8 hours.
Insufficient uterine tone resulting in atony can potentiate hemorrhage and adverse outcomes for the parturient. Oxytocin is the first pharmacologic agent used, followed by methylergonovine, carboprost, and misoprostol. The American Congress of Obstetricians and Gynecologists (ACOG) recommends the sequential use of oxytocin, followed by methylergonovine, carboprost, misoprostol, then surgical intervention for cases of refractory uterine atony. Many studies have examined the effect and dosage of intravenous uterotonics, including oxytocin. Although there are anecdotal reports of using intravenous bolus or rapid infusion of methylergonovine, no randomized trial has compared efficacy and side effects of these two routes of administration. Investigators hypothesize that intravenous methylergonovine reduces the time to adequate uterine tone (the tone at which the uterus is adequately contracted to prevent atony after delivery of neonate), decreases the total dose of methylergonovine to contract the uterus, and therefore produces fewer side effects of hypertension, nausea, and vomiting. Reducing the time to achieve adequate uterine tone is likely to decrease postpartum hemorrhage.
The objective of the study is to demonstrate whether cooling the uterine smooth muscle during cesarean section (following delivery of the fetus) will promote better uterine contraction and involution resulting in lower blood loss, use of fewer uterotonic medications, and fewer hysterectomies following cesarean section for dysfunctional labor.
This study aims to compare role of a prophylactic predefined intravenous Tranexamic Acid dose versus intraoperative Uterine Cooling in reducing blood loss and incidence of postpartum hemorrhage at secondary CS.
