Filter by:Caesarean delivery is inevitably associated with a higher amount of blood loss vis-à-vis primary postpartum haemorrhage, when compared to vaginal delivery. Oxytocin use in tropical developing countries for the reduction blood loss at caesarean section have been met with challenges of ineffectiveness due to poor transportation, inadequate storage and drug adulteration. Therefore, there is a need for an effective, temperature stable uterotonic with a lesser risk of adulteration. The study is aimed at evaluating the effectiveness and safety of adjunctive sublingual misoprostol in reducing intraoperative blood loss at caesarean section.
Postpartum hemorrhage (PPH) remains to be one of the leading causes of maternal morbidity and mortality. It has been noted that an increasing number of PPH is attributed to the increased incidence of uterine atony. Myometrial contraction is affected by the choice of anesthetic technique and medications during cesarean delivery (CD). It has been proven that exposure to oxytocin during labor results in a decrease in myometrial contractions. Dexmedetomidine is a drug which has been used in obstetric practice due to its desirable effects such as decreasing pain, reduced elevation in blood pressure and heart rate, sedation, and diminished anesthetic requirement. It has been used as an adjunct during spinal or epidural anesthesia during CD and even during general anesthesia for some obstetric surgeries. The use of dexmedetomidine has been continuously rising due to its favorable effects. Its use as an adjunct in general anesthesia for obstetrical surgeries has been shown to have promising advantages. During this pandemic, dexmedetomidine has been utilized largely as a sedative in critically ill and intubated patients. This does not exclude critically ill pregnant patients who may also need to deliver urgently. Thus, it is important to investigate its effect on uterine contractility on this particular group of patients. The investigators hypothesize that dexmedetomidine causes a dose-dependent increase in contractility of the pregnant human myometrium, both spontaneous and oxytocin-induced.
The objective of this study is to assess the effect of TA treatment on decline in Hb levels following vaginal delivery with an episiotomy, compared to a control group not receiving TA.
This will be the first, definitive, randomized control trial (N=424) to test the hypothesis that the Jada® System is effective, safe and cost-effective in treating PPH, compared to standard care.
In part 1 of the study, the investigators conducted a prospective, open-label, dose finding pharmacokinetic (PK) study in 43 pregnant 3rd trimester women scheduled for non-emergent cesarean section. The investigators administered three doses of the drug (5 mg/kg, 10 mg/kg and 15 mg/kg) in an escalating fashion by cohort with the lowest dose first. The drug was administered intravenously at the time of umbilical cord clamping for a non-emergent cesarean section. A maximum of 1 gram was administered. TXA serum levels at several time points after delivery were assayed to see if they reach the target plasma concentration of 10 microg/mL. A PK model was constructed for determining the optimal TXA dose administered at parturition. In part 2 of the study, the investigators aim to compare PKPD endpoints using prophylactic TXA via IV and IM routes administered pre-cord clamp. The investigators will administer 1000 mg TXA within 10 minutes of skin incision via intravenous infusion (up to n=15), intravenous bolus < 2 minutes (up to n=15) and intramuscular injection (up to n=15). The investigators will target women undergoing scheduled cesarean delivery greater than 34 weeks gestation, women undergoing vaginal delivery > 34 weeks of gestation and morbidly obese women (BMI>50) undergoing either a vaginal or cesarean delivery. The investigators will use advanced modeling techniques to determine time to achieve PKPD targets and duration remaining at those targets. The goal will be to determine how the optimal dose may vary if route of administration is modified. The investigators plan to enroll 45 patients in addition to the 43 that were enrolled during part 1. Our goal is to 30 participants, but the investigators will enroll 45 to account for lost to follow-up. The investigatorsalso aim to enroll 30 patients undergoing vaginal delivery and 30 morbidly obese women (BMI > 50) undergoing either a vaginal or cesarean delivery but the investigators will enroll 45 patients for each of these groups to account for loss to follow up. In addition, the investigators will enroll 30 pregnant patients receiving no medication acting as the control group, but the investigators will enroll 45 to account for loss to follow up.
This study is designed to determine the minimal effective oxytocin maintenance infusion required in labouring women undergoing cesarean delivery to achieve the best effect. Oxytocin is a drug that is routinely used to help the uterus to contract and keep it contracted after delivery. Consequently, it will help to reduce blood loss after delivery. In order to determine the minimal effective dose, the investigators will conduct a dose-finding study. The first patient will receive a set oxytocin infusion. The next patient's infusion dose of oxytocin, will either increase or decrease, depending on how the previous patient responds in terms of uterine tone. If the response is satisfactory with the infusion dose used, the next patient will either receive the same infusion dose or it will be decreased depending on a probability of 1:9. If the response is not satisfactory, then the infusion dose will increase for the next patient. The dose for each patient will be determined based on the results of the uterine contraction of the previous patient. The investigators hypothesize that the ED90 of the oxytocin infusion rate to maintain adequate uterine tone in labouring women with induced or augmented labour undergoing cesarean delivery, following an initial effective bolus dose, would be lower than 0.74 IU/min (44 IU/h), which was found as the ED90 in a previous study, without an initial bolus dose prior to the infusion.
To determine the effectiveness of using two medications simultaneously versus one medication, as is standard of care, in preventing early postpartum hemorrhage. There have been studies that looked at giving two medications and that there were reduced odds of postpartum hemorrhage. Specific Aim 1: Determine if double simultaneous uterotonic agent regimen (misoprostol and oxytocin) is superior to single agent (oxytocin only) in reducing postpartum hemorrhage. Specific Aim 2: Determine any potential side effects of a double simultaneous uterotonic agentregimen (misoprostol and oxytocin) versus a single agent (oxytocin only).
Postpartum haemorrhage is the common cause of maternal death worldwide. The primary purpose of this study is to identify the maternal outcomes after PPH. The highlighted outcome is the anesthetic management including rate of blood transfusion and incidence of patient experiencing massive blood transfusion. The secondary purposes of this study are amount of blood loss, causes of PPH and other outcomes that related to PPH such as the rate of hysterectomy and postoperative outcome eg. congestive heart failure, acute kidney injury and TRALI etc. Additionally, incidence of PPH will be studied. Data collection will be made to identify the cause of PPH, anesthetic techniques that may related to the amount of hemorrhage, medical treatment for PPH and neonatal outcomes. We also aim to obtain the rate of ICU admission and revealed the factors involving the ICU admission in PPH patients underwent cesarean delivery.
306 patients will be divided randomly in to 2 GROUPS: - control group: 153 patients will receive Oxytocin 10 IU I.V shot administered at the time of delivery of the anterior shoulder of the baby for both groups in prevention of postpartum haemorrhage,followed by active management of the third stage of labor by administration of oxytocin 5 IU units IM and waiting for signs of placental separation then controlled cord traction (CCT) to the umbilical cord while applying simultaneous counter-pressure to the uterus, through the abdomen(Brandt Andrews maneuver) - study group:156 patients received Oxytocin 10 IU I.V shot at the time of delivery of the of the anterior shoulder of the baby according to the WHO recommendation .Then oxytocin is stopped and cervical traction (Amr maneuver )is applied. In the maneuver,sustained traction downward and posteriorly was applied to anterior and posterior lips of the cervix using ovum forceps for approximately 90 seconds. The traction should be adequate to allow the cervix to reach the vaginal introitus. Meanwhile (CCT ) is avoided and watchful waiting for signs of placental separartion till 90 seconds end. Massage is not employed but the fundus is frequently palpaple to insure it doesnot become atonic and filled with blood from placenta separation. In cases whom placental separation did not occur within the 90 seconds, we removed the ovum forceps and waited for 30 min for the placental separation .
Postpartum hemorrhage, is one of the most deadly complication of pregnancy worldwide and major cause of maternal mortality especially in third world countries .1 PPH affects about 5% of all women giving birth around the world 2 .Primary PPH is defined as ≥500 mL blood loss after vaginal delivery or ≥1000 mL after CS delivery within 24 hours after birth1 . Globally, almost one quarter of all maternal deaths are linked with PPH 2. Due to the high prevalence of anemia among pregnant women in low-resource settings, the outcome of PPH is often deteriorated, resulting in damaging health consequences 3. Roughly in 70% of cases of primary pph are due to uterine atony11. Uterine atony is due to loss of contraction and retraction of myometrial muscle fibers can lead to severe hemorrhage and shock. There are several reasons behind uterine atony including maternal anemia, fatigue due to prolong labour and rapid forceful labour. Blood loss is double in caesarean section due to use of increased anesthetic agents4. According to WHO use of oxytocin (10 IU, IM /IV) is recommended for prevention of PPH for all births2. Despite its effectiveness, 10-40% of cases need additional uterotonics to ensure good uterine contraction.5 After oxytocin , Misoprostol is increasingly known as a potential treatment option for PPH 5 .Misoprostol is easily available , rapid acting , and cost effective with minimal side effects, however in caesarean section owing to the effect of anesthesia limits its use . In recent study conducted at Egypt, oxytocin plus misoprostol (study group) is compared with oxytocin alone (control group). Incident of pph was significantly lower in study group (p=0.018), as in study group (1.33%) than control group (6.67%)8. Misoprostol is an autacoid substance and act better if placed closed to target organ 9. Several routes of misoprostol, with or without oxytocin, and its result on intrapartum and postpartum hemorrhage are described in the literature. The practice of misoprostol by the intrauterine route during caesarean section is under trial.10. Aim of study is to observe the effectiveness of intrauterine misoprostol in addition to oxytocin to minimize the blood loss during caesarean section.
