Filter by:Post-partum haemorrhage due to placenta previa is usually from the placental bed at the lower uterine segment and it occurs after the placenta separation. Although, nowadays the obstetrician can diagnose placenta previa before delivery, it is still one of the important causes of maternal mortality . Hysterectomy can be the only effective action to take, although it carries many morbidities for the women especially those with low parity. Uterine packing considers as a line of treatment before performing surgical procedures in postpartum hemorrhage resulting from placental site bleeding. It can save life, avoid laparotomy and save uterus. Nowadays, the use of intrauterine balloons have been developed and become effective for the control of placental site bleeding not responding to medical treatment. The 2-way Foley's Cather has many advantages over the gauze packing; First, it allows drainage of blood so no occult bleeding could be accumulated inside the uterus as in uterine gauze, second the removal of the Foley's Cather balloon is easy and not a painful, third, the removal of 2-way Foley's Cather could be gradually as a test of its effectiveness before complete removal .
This is a prospective observational study of transperineal ultrasound between 24-42 weeks gestation and a prospective longitudinal observational study in all term (37-42 weeks) labouring women.
Objective: To assess the efficacy of lower uterine compression sutures (involved bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch) as a conservative treatment for the treatment of postpartum hemorrhage in women with placenta previa complete centralis. Method: This prospective study of 50 women with postpartum hemorrhage following removal of placenta previa complete centralis during elective cesarean section. All 50 patients will have lower uterine compression sutures (involving bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch). All patients will be followed postpartum for evaluation of uterine cavity and menstrual cycles
This trial will address the effect of uterine artery ligation during Cesarean section in cases with placenta previa to decrease blood loss.
In many low-income countries, the use of ultrasound by medical officers and non-physician health care staff (e.g., midwives) for antenatal identification of high risk pregnancies is a new intervention requiring authoritative investigation. The primary hypothesis to be assessed in this study is that antenatal ultrasound screenings performed by medical officers and non-physician health care staff will significantly reduce a composite outcome consisting of maternal mortality and maternal near miss, stillbirth and neonatal mortality in low-resource settings. Underpinning this hypothesis are two assumptions. The first assumption is that antenatal detection of complicated pregnancies will lead to appropriate referral at the right time for complicated pregnancies to comprehensive emergency obstetric and neonatal care (EmONC) facilities. The second assumption is that ultrasound's introduction will increase antenatal attendance leading to greater rates of institutional delivery. To assess these underlying assumptions beyond the composite end point, this study will investigate the health system impact of compact ultrasound. Secondary outcomes include antenatal attendance rates, institutional delivery rates at basic EmONC facilities, referral rates to comprehensive EmONC facilities, cesarean section rates (both planned and emergent) and an assessment of medical officers and non-physician health care provider ultrasound competence and training quality.
Cesarean section (C/S) is an operation most commonly performed in Obstetrics and Gynecology Clinics. Complications related with incomplete healing of Kerr uterine incision after C/S (adhesions, separation (dehiscence), endometritis, endometriosis, anomalous placentation in subsequent pregnancies, incomplete or complete uterine rupture in subsequent pregnancies, ...) are very important issues. Classically Kerr incision is repaired with continuous locked suturing. Purse string suturing of Kerr incision may reduce the size of the incision and in turn may reduce short and long term complications. For this reason, the investigators aimed to compare two closure techniques.
The objective of our study is to determine the clinical utility related to the maintenance oral nifedipine therapy in patients with symptomatic placenta previa. This study is a prospective, randomized controlled trial with the inclusion, after 24 weeks gestation, of hospitalized patients with symptomatic placenta praevia. All patients may initially receive oral nifedipine therapy with steroid prophylaxis for 48 hours. After then, patients are randomly assigned to receive either oral nifedipine (20 mg every 8 hours) or placebo (one every 8 hours) until 37 weeks of gestation. The primary outcome for the trial is the length of pregnancy in days after the enrollment. A sample size calculation is designed to detect at least a 14 -day difference in time gained in patients with maintenance oral nifedipine therapy. A sample size of about 52 patients per group would have a 80 % chance of detecting this difference at the 5 % level of significance.
