Balloon Tamponade in Fatal Hemorrhage
Intrauterine balloon tamponade was performed in 20 maternal death cases out of 104 fatal critical obstetric hemorrhage incidents recorded between 2010 and 2023, Cureus reported in a nationwide registry-based study published from data collected by the Japan Association of Obstetricians and Gynecologists.
Most patients presented with hemorrhagic shock and coagulopathy at the time of placement. Massive blood loss and severe hypofibrinogenemia marked these clinical environments.
Registry data shows causes of maternal deaths
The study analyzed data from the maternal death registration system of the Japan Association of Obstetricians and Gynecologists covering reports filed from January 2010 through December 2023. Among 590 total maternal deaths reported during this timeframe, critical obstetric hemorrhage accounted for 17.6% of the fatalities, according to Cureus.
The primary underlying causes in the subset receiving intrauterine balloon tamponade included amniotic fluid embolism with severe coagulopathy in 12 patients. Placental abruption accounted for five cases, while placenta accreta spectrum occurred in two instances and atonic bleeding in one. Median cumulative blood loss reached 1,790 mL at delivery, with 88.9% of evaluated patients exceeding 1,000 mL of blood loss.
Subsequent Management Intervals
Subsequent management procedures such as maternal transfer, transcatheter arterial embolization, or hysterectomy were performed in 14 women. Among 11 evaluable patients in this group, the decision for subsequent intervention was made more than 30 minutes after balloon placement in five cases, Cureus reported.
Transfusion had been initiated prior to the decision for subsequent management in nine of the 14 patients. In six additional cases, patients remained too hemodynamically unstable for subsequent management despite receiving systemic support including endotracheal intubation, vasopressors, and blood transfusions.
Frequently Asked Questions
What criteria defined critical bleeding in the guidelines?
National guidelines recommended intervention when blood loss reached at least 1,000 mL after delivery or when the shock index exceeded 1.0, Cureus reported.
How many delivery facilities transferred patients?
All patients who delivered at obstetric clinics or obstetric hospitals were transferred to a higher-level institution, totaling 16 maternal transfers across the cohort, according to Cureus.
What were the recorded fibrinogen levels at placement?
Fibrinogen levels dropped below 110 mg/dL in all 11 patients with available results, including four values falling below the detection limit, Cureus stated.
