A 28-year-old G4P3 at 41 weeks presents to the ED via EMS. She is in active labor. On exam, a neonatal head is visible. Two minutes later, you deliver a healthy vigorous baby boy and hand him to your colleague. You notice persistent bleeding from her vaginal canal. Her tachycardia climbs to 110 bpm and her latest blood pressure is 78/48 mm Hg. We review postpartum hemorrhage (PPH) and the 4 T’s – a memory aid to help ED providers manage this life-threatening presentation.(more…)
Welcome to the Obstetrics and Gynecology (Ob/Gyn) Module! After carefully reviewing all relevant posts from the top 50 sites of the Social Media Index, the ALiEM AIR Team is proud to present the highest quality online content related to Ob/Gyn emergencies. 10 blog posts within the past 12 months (as of July 2018) met our standard of online excellence and were curated and approved for residency training by the AIR Series Board. We identified 2 AIR and 8 Honorable Mentions. We recommend programs give 4 hours (about 25 minutes per article) of III credit for this module.
Maternal cardiac arrest is a low-frequency, high-risk pregnancy complication with 2 lives at stake. Incidence is approximately 1 in 12,000 to 50,000 pregnancies with a greater than 40% mortality rate. Understanding physiologic changes of pregnancy and how to perform a perimortem cesarean section (resuscitative hysterotomy) are critical aspects of caring for maternal cardiac arrest. ALiEM Cards: Maternal Cardiac Arrest, written by Drs. Jeffrey Sakamoto, Collin Michels, Nikita Joshi, and Rebecca Bavolek, reviews the causes, management pearls, and summarizes the perimortem cesarean delivery.
Tranexamic acid (TXA) is a synthetic form of the amino acid lysine that binds to receptors on plasmin and prevents it from breaking down fibrin clots. Numerous studies have investigated its utility in preventing or treating traumatic hemorrhage, and the World Health Organization now includes TXA on its list of Essential Medicines. In addition to trauma, TXA may be effective in other clinical scenarios relevant to Emergency Medicine, including gynecological hemorrhage and epistaxis. ALiEM Cards: TXA, written by Dr. Sam Ashoo, reviews the dosing and potential indications for TXA use in the ED.
Preeclampsia is on a spectrum of pregnancy related illness that includes eclampsia and HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets – debate exists about if this is a separate entity altogether). It carries a high mortality for both mom and baby, and can lead to a number of complications including pulmonary edema, hepatic rupture, placental abruption, and seizures (eclampsia). Created by Dr. Sam Ashoo, ALiEM Cards: Preeclampsia gives you a rapid review of its presentation, criteria, and management.
Trick of the Trade: Linear Transducers for Point of Care Ultrasound in Intrauterine Pregnancy Evaluation
The volume of women presenting to the emergency department (ED) with newly diagnosed first-trimester pregnancies and suspected ectopic pregnancies sometimes seems like an infinitely growing number. As ED physicians, proper identification of an intrauterine pregnancy (IUP) in these patients is of paramount importance and the initial imaging test of choice for many has become bedside point-of-care ultrasound (POCUS).
Welcome to another ultrasound-based case, part of the “Ultrasound For The Win!” (#US4TW) Case Series. In this case series, we focus on a real clinical case where point-of-care ultrasound changed the management of a patient’s care or aided in the diagnosis. In this case, a 20-year-old woman presents with first-trimester vaginal bleeding.
