View clinical trials related to Placenta Previa.
Filter by:Antepartum hemorrhage is defined as bleeding from or within the female genital tract, occurring from 24+0 weeks of pregnancy and till delivery of the fetus. Antepartum hemorrhage occurs in 3-5% of pregnancies and is an important cause of perinatal and maternal morbidity and mortality worldwide. Placenta previa is a placenta inserted wholly or in part into the lower segment of the uterus. It is classified by ultrasound to Placenta previa major degree when the lower edge of the placenta lies within 2 cm from the internal cervical os and Placenta previa minor degree if the lower edge of the placenta at lower uterine segment but more than 2 cm from internal os. Placenta previa is responsible for 0.03% of maternal mortality and 8.1% of perinatal mortality of 8.1% in the developed world and much more in developing countries. Many studies in literature proved the positive correlation between the Placenta previa and preterm uterine contractility and also reported that large proportion of women who have Placenta previa associated with vaginal bleeding will have subclinical uterine contractions before the onset of evident vaginal bleeding. There are many tocolytic agents may have a role in conservative management of Placenta previa such as magnesium sulfate and β-sympathomimetics .Progesterone is essential for continuation of pregnancy and helps in maintenance of pregnancy . Delaying delivery may reduce the fetal morbidity by helping maturity of vital organs. In 2003 Meis et al. in a large randomized placebo-controlled trial found a significant reduction in recurrent preterm birth before 37 weeks for women who received 17αHP-C versus a control group receiving placebo (36.3% versus 54.9%).
Pfannenstiel incision of skin and opening of the anterior abdominal wall in layers. - The loose peritoneum of the lower uterine segment is dissected downwards to mobilize the urinary bladder and expose the lower uterine segment. - Uterine artery ligation was performed by grasping the broad ligament with thumb anterior and the index finger lifting the base below the site uterine incision; the uterine artery was singly ligated with No. 1 vicryl suture. Myometrium was included so that uterine vessels are not damaged. - Cresenteric lower uterine segment incision was performed as usual. Higher incisions were performed in cases where the traditional incision was expected to be directly through the placenta Delivery of the baby and placenta. - Closure of the uterine incision in 2 layers with N0. 1 vicryl suture. - Closure of the anterior abdominal wall in layers
Tranexamic Acid Use in Elective Cesarean Section for Women With Placenta Previa
Placenta previa and accreta both could potentially cause serious postpartum hemorrhage and even maternal death. Interventional radiological techniques have been developed to limit massive hemorrhage during caesarean section. This study investigated the efficacy of prophylactic internal iliac artery balloon catheterization in management for placenta previa and accreta.
Bleeding is the most significant cause of maternal death worldwide with more than half of those occurring within the first day of delivery. About 10.5% (some estimate as high at 12-17%) of live births world-wide, or about 14 million births, are complicated by postpartum hemorrhage; a woman dies every 4 minutes from postpartum hemorrhage. Uterine atony and placenta accreta are the two leading causes of postpartum hysterectomies with up to 64% of Cesarean hysterectomies done for abnormally adherent placentation
The purpose of this pilot study is to determine if intravenous tranexamic acid (TXA) is effective for reducing blood loss during high risk surgical procedures related to placenta previa and placenta accreta. TXA is currently used in other types of surgery for patients who are expected to have a large blood loss, such as orthopedic or open heart surgery.
The purpose of this study is to assess the efficacy of random placenta margin incision for hemorrhage control during cesarean section of complete placenta previa pregnancies.
The Bakri intrauterine balloon can achieve haemostasis in cases of postpartum haemorrhage, including haemorrhage associated with placenta previa by compressing the lower uterine segment.
This study evaluate role of tranexamic acid in reducing blood loss among pregnant women undergoing cesarean section because of placenta previa .Half of participants will receive tranexamia acid drug While the other half will receive placebo.
Placenta previa percreta is a dangerous complication during surgery. Due to the high risk of hemorrhage, most parturients with placenta previa have to accept cesarean section. In this study investigators compare the effect of different anesthetic techniques on these patients.
