Laboring Under Pressure Episode 2: Postpartum Hemorrhage with Dr. Kiersten Williams
Emergency Medical Minute
Trans-Examic Acid and Uterine Artery Embolization
A discussion on the use of trans-examic acid (TXA) to prevent clot breakdown and stop bleeding, as well as the option of uterine artery embolization (UAE) for controlling uterine bleeding.
Contributor: Kiersten Williams MD, Travis Barlock MD, Jeffrey Olson MS2
Summary:
In this episode, Dr. Travis Barlock and Jeffrey Olson meet in the studio to discuss a clip from Dr. Williams' talk at the "Laboring Under Pressure, Managing Obstetric Emergencies in a Global Setting" event from May 2023. This event was hosted at the University of Denver and was organized with the help of Joe Parker as a fundraiser for the organization Health Outreach Latin America (HOLA).
Dr. Kiersten Williams completed her OBGYN residency at Bay State Medical Center and practices as an Obstetric Hospitalist at Presbyterian/St. Luke's Medical Center in Denver, Colorado.
During her talk, Dr. Williams walks the audience through the common causes and treatments for post-partum hemorrhage (PPH).
Some important take-away points from this talk are:
-
The most common causes of PPH can be remembered by the 4 T's. Tone (atony), Trauma, Tissue (retained placenta), and Thrombin (coagulopathies).
-
AV malformations of the uterus are probably underdiagnosed.
-
Quantitative blood loss is much more accurate than estimated blood loss (EBL).
-
The ideal fibrinogen for an obstetric patient about to deliver is above 400 mg/dl - under 200 is certain to cause bleeding.
-
Do not deliver oxytocin via IV push dose, it can cause significant hypotension.
-
Tranexamic Acid is available in both IV and PO and can be administered in the field. The dose is 1 gram and can be run over 10 minutes if administered via IV. It is best if used within 3 hours of delivery.
-
When performing a uterine massage, place one hand inside the vagina and one hand on the lower abdomen. Then rub the lower abdomen like mad.
-
A new option for treating PPH is called the JADA System which is slimmer than a Bakri Balloon and uses vacuum suction to help the uterus clamp down.*
-
Another option for a small uterus is to insert a 60 cc Foley catheter.
-
In an operating room, a B-Lynch suture can be put in place, uterine artery ligation can be performed, and as a last resort, a hysterectomy can be done.
*EMM is not sponsored by JADA system or the Bakri balloon.
