COVID19, Preeclampsia, and Clots. Jul 14, 2020

Show notes

COVID19 can have varied clinical manifestations. In pregnancy, new data has highlighted its potential to cause a “preeclampsia like syndrome“. This, together with the increased thrombotic state of COVID-19, elevates the risk for VTE above that of pregnancy alone. Can TXA be used for PPH in these cases? In this podcast we will review these 2 high risk clinical manifestations of COVID-19 in pregnancy.

Tamoxifen for Nexplanon Bleeding? A New RCT. Jul 12, 2020

LARCS are endorsed by the ACOG due to the high efficacy. However, unpredictable bleeding can affect continuation rates. A new RCT has evaluated the use of tamoxifen to control and prevent future abnormal bleeding with etonogestrel implant use. Does this work? What is the MOA? In this session, we will summarize this new publication (published ahead of print) in Obstetrics and Gynecology.

Did you know that silver wire helped to dramatically reduce maternal mortality at cesarean section? And what does the Goodyear Rubber Company have to do with surgical techniques? In this episode we will wrap up our walk through history reviewing CS’s AMAZING History.

Cesarean’s AMAZING History (Part 1) Jul 09, 2020

Show notes

What does a pig gelder, a woman dressed as a man, and the Queen of England all have in common? The answer: ALL CONTRIBUTED TO CS’s history!

Pregnant & Prone for Resp Support Jul 05, 2020

Show notes

Prone positioning during invasive mechanical ventilation improves oxygenation, as shown in large randomized clinical trials of patients with ARDS. In an RCT that included 466 patients with moderate and severe ARDS, prone positioning for at least 16 hours per day with protective mechanical ventilation reduced 90-day mortality. Is prone positioning for respiratory support possible in pregnancy? In this session we will cover the beneficial effect of probe positioning and summarize an article (EPUB) soon to be in print in Obstetrics & Gynecology regarding prone therapy in pregnancy (Tolcher et al).

Fetal Gastroschisis. Jul 02, 2020

Gastroschisis occurs in about 1 in 1800 births in the US. Does this abdominal wall herniation usually occur to the right or left of the umbilical cord? Is this condition tied to chromosomal/genetic syndrome? What about antepartum fetal surveillance? Is a cesarean birth required? In this episode, we will review the SMFM and CDC data regarding management of gastroschisis.

What about antepartum fetal surveillance? In this session, which is Part 1, we will review the SMFM guidance regarding polyhydramnios.

Placenta Accreta Spectrum Jun 22, 2020

Show notes

Placenta accreta spectrum, formally known as morbidly adherent placenta, refers to a range of pathologic adherence of the placenta (accreta, increta, and percreta). There is significant risk of maternal morbidity and mortality including risk of blood transfusion, life-threatening hemorrhage, and hysterectomy. In this session, we will review the obstetric care consensus by the ACOG and SMFM regarding this condition (obstetric care consensus # 7).
