Treating PPH: A novel vacuum-induced hemorrhage control device
A new FDA-cleared device is an option for PPH management, but further studies are needed to evaluate its effectiveness compared with other devices for PPH. These experts, with experience in its use, explain how it works and discuss treatment success rates reported in a prospective study.
CASE continued Patient’s history reveals risk factors
You review with Ms. B. that she had several risk factors present during labor. She had a large baby and a protracted labor. Knowing her history in this pregnancy will allow the clinical team to be prepared for a potential recurrent hemorrhage and to respond proactively to bleeding.
Consider the management options
The initial treatment for PPH includes bimanual massage, oxytocin, and other uterotonics (methylergonovine, 15-methyl prostaglandin F2α, and misoprostol). While various algorithms are available on the order of treatment, a single agent has not been shown superior to others.12 The antifibrinolytic medication tranexamic acid also was shown to reduce the risk of death from obstetric hemorrhage in the international WOMAN trial.13
While these agents often are used simultaneously to achieve hemostasis, their systemic effects are associated with contraindications. Specifically, F2α prostaglandins cannot be used in patients with asthma or active hepatic, pulmonary, or cardiac disease. Ergot derivatives cannot be used in patients with hypertension, pre-eclampsia, or cardiovascular disease. Given the rising rate of medical comorbidities during pregnancy, such contraindications limit the treatment options for many patients.
In cases in which medical management is not sufficient or is contraindicated for controlling hemorrhage, second-line treatment includes the use of tamponade techniques, such as intrauterine packing or balloons. The tamponade applies pressure directly to the placental implantation site for 12 to 24 hours, which allows time for the uterus to contract and return to normal tone. While this method may seem counterintuitive to achieving uterine tone, studies suggest a success rate between 75% and 86% with balloon tamponade.12
Third-line treatment options are increasingly invasive but should be used to prevent further maternal morbidity and mortality. These include uterine artery embolization and surgery. Uterine artery embolization is an option for a stable patient at a center with available interventional radiology services. If embolization is either not successful or not available, an exploratory laparotomy should be performed. Uterine compression sutures can be placed along with vascular ligation sutures of the uterine arteries (O’Leary sutures) and the hypogastric arteries. If all other methods have failed, a hysterectomy is the definitive treatment for hemorrhage.
CASE continued Patient desires an alternative to tamponade if needed
Following your visit, Ms. B. has an ultrasound scan that shows a dichorionic diamniotic twin pregnancy. She also has a microcytic anemia. After you discuss iron supplementation with the patient, she asks if there are any other options should medical management fail in the event of a recurrent hemorrhage. While intrauterine tamponade balloon did treat her hemorrhage, she was not happy with the length of time it had to remain in place, the discomfort while it was used, and the disruption to her planned recovery. You inform her of a new treatment option available for PPH, a vacuum-induced hemorrhage control device that was recently FDA cleared.
