FHT Baseline Change (110-160) in Labor: Danger, or Disregard?

In 2002, the National Institute of Child Health and Human Development (NICHD) proposed the 3-Tier fetal heart rate (FHR) classification system that was subsequently adopted by many organizations, categorizing tracings into three groups: Category I (normal), Category II (indeterminate), and Category III (abnormal). Recently, our podcast team received an interesting question form one of our podcast family members: “If there is a change in the fetal heart rate tracing intrapartum, but it is still in the normal range (like 120 going to 150)- and variability is normal, is that an abnormality? And what is meant by a ‘ZigZag’ FHT pattern (different than marked variability)?”. That is a fantastically complex question…and we will explain the answer in this episode.1.

Podcast Family, in our immediate past episode we tackled the discrepancy that is often found between a clinical diagnosis of intra-amniotic infection/chorioamnionitis and histological chorioamnionitis. From that episode, we received a fantastic question from one of our podcast family members: Can a patient have IAI without fever? That question is really deep and highlights a gap in the current diagnostic scheme/ criteria from the ACOG. Listen in for details!1. ACOG CO 7122. Sukumaran S, Pereira V, Mallur S, Chandraharan E.

Welcome to "Labor & Delivery Debrief," the podcast where we tackle your toughest questions about childbirth and maternal health. Today, we're diving deep into a fascinating and critical topic sent in by one of our listeners, Sarah. Sarah asks: "Is it possible for a clinical diagnosis of chorioamnionitis to not be confirmed by placental histology? And if so, how is that possible?" This is a fantastic question that touches on the complexities of intrapartum clinical diagnosis of intraamniotic infection (IAI), also commonly known as chorioamnionitis. We'll explore the nuances of clinical versus histological findings, the diagnostic criteria, and why these two assessments don't always perfectly align. Get ready for a detailed discussion that will shed light on this important aspect of obstetric care.1. ACOG CO 712; 2017 (2025)2. Romero R, Pacora P, Kusanovic JP, et al.

Depo-Provera was approved in 1992 by U.S. regulators. About 1 in 4 sexually active women in the United States have used the shot at some point, according to the U.S. Centers for Disease Control and Prevention (CDC). Meningiomas are common intracranial tumors with a female predominance. In fact, they are the most common primary brain tumor in women, with an incidence of approximately 12.76 per 100,000 in the general female population. The vast majority of these tumors are benign (World Health Organization [WHO] grade 1) while 15% to 20% of these tumors can behave atypically (WHO grade 2) and rarely, in 1% to 2% of cases, these tumors can be malignant (WHO grade 3). We covered the relationship between Depo-Provera, as a contraceptive agent, and brain meningiomas back in March 2024. With the increase in data, the ACOG released a patient centered counseling tool titled, “Counseling Patients on Birth Control Injection and Meningioma”. The most recent update on this story comes from the FDA, which has granted a medication label change to Depo-Provera (Pfizer) warning of this association. Even though association does not prove causation, the association between depo and meningiomas seems strong (with new data from the US). Does this warning extend to other progestins?

The second stage of labor, characterized by active pushing and the descent of the fetal head, can be a challenging and prolonged phase for both mother and baby. Various interventions have been explored to optimize this stage, and one such technique involves the application of vaginal lubricants. The rationale behind this approach is to reduce friction between the fetal head and the birth canal, potentially leading to smoother and faster delivery. Does this seemingly simple technique work? Does the ACOG mention this in the CPG 8 from January 2024? What does the latest research tell us about its effectiveness in assisting or speeding up the birthing process? Listen in for details.1.

It’s so interesting to see how medical evidence evolves, and changes, over time. The result of course is that clinical practice evolves and changes as well. The story of umbilical cord management at time of delivery highlights this very issue very well. The ACOG first recommended delayed cord clamping (DCC) in 2012, for preterm infants, as data showed marked improvement in neonatal outcomes in that population. In this episode, we will briefly walk through the timeline from 2012 to the latest update on DCC which came from the AAP in October 2025, just one month after the ACOG had their DCC update. This story also exemplifies how professional medical societies don’t always have the SAME recommendations, with small tweaks, in their guidance. So, Dr Chapa and I will summarize these key updates…Listen in for details!1. ACOG 2012: DCC for preterm infants only 2.

Podcast Family, we have covered PCOS on this show many times in the past; and yet- again, there is new information!

Major health organizations, including the CDC and ACOG, recommend universal Hepatitis C Virus (HCV) screening for all pregnant women during each pregnancy and at time of delivery. Ideally, pregnant women should be screened for hepatitis C virus infection at the first prenatal visit of each pregnancy. If the antibody screen result is positive, hepatitis C virus RNA polymerase chain reaction testing is done to confirm the diagnosis. The risk of perinatal transmission of HCV is up to 9%, with at least one-third of transmissions occurring antenatally. While antiviral therapy is recommended for Hepatitis B in pregnancy with a viral load greater than 200,000 international units/mL to decrease the risk of vertical transmission, the same is not the case for Hep C. According to the ACOG CPG #6 from September 2023, there are no standard treatment protocols for Hep C in pregnancy but a new publication from the PINK journal (7 Dec 2025) is calling for a change. That new publication is, “Hepatitis C Treatment During Pregnancy: Time for a Practice Change”. Listen in for details. 1. ACOG CPG #6; Sept 20262. Bhattacharya D, Aronsohn A, Price J, Lo Re V.

Welcome to the no spin podcast. In today's episode, we're tackling a subject that's gaining traction but carries significant risks: the freebirth and wildbirth movement. We'll explore the rising trends of unassisted childbirth, where individuals choose to forgo professional medical care during labor and delivery- or during the prenatal period altogether, and the potential devastating outcomes associated with these practices. Join us as we unpack the motivations behind these choices, the lack of evidence supporting their safety, and the serious harms that can arise for both parent and baby. We'll be examining medical guidelines, and real-world consequences to provide a comprehensive and nuanced understanding of this complex issue. It’s a balance between patient autonomy, advocacy, and potentially allowing an atrocity. Listen in for details. 1.
