Study Notes
OB/Gyn Emergencies Overview
- GYN emergencies can lead to significant adverse events with potential mortality and morbidity.
- Adverse events can be categorized into major and minor impacts on patient health.
Risk Assessment for Contraceptive Users
- Combined Oral Contraceptive (COC) users face increased risks for venous thromboembolism (VTE).
- Specific risks associated with COC containing levonorgestrel or norethisterone show a threefold increase in VTE risk.
- During pregnancy, the relative risk of VTE escalates significantly to twelvefold.
Management of GYN Issues
- Non-pregnancy-related GYN problems in nonpregnant patients are typically handled in Emergency Departments (ED).
- Hospitals usually operate a separate obstetric Emergency Department or OB triage area for pregnant patients.
- Access to the OB ED/Triage is generally restricted to patients beyond 12-24 weeks of gestation; earlier in pregnancy, these patients are directed to the general ED.

Cardiovascular and Related Conditions
- Heart disease and vascular disease are significant contributors to maternal mortality.
- Pregnancy increases coagulability, raising the risk of thrombotic events.
- Cardiomyopathy is the leading cause of maternal death occurring more than 42 days postpartum.
- Pre-eclampsia can cause severe organ damage and is associated with heightened maternal mortality.
- Chronic hypertension raises the risk of developing pre-eclampsia and exacerbates preexisting vascular damage during pregnancy.
- Deep vein thrombosis (DVT) and pulmonary embolism (PE) risk increases 12 times during the postpartum period, with a recovery time of 4-6 weeks.
- Any chronic medical condition may deteriorate during pregnancy, impacting overall maternal health.
Mental Health Conditions
- Mental health disorders significantly influence maternal death rates, with suicide and homicide being key factors.
- Postpartum depression is prevalent and can lead to suicidal thoughts or actions, increasing risk of maternal mortality.
- Postpartum psychosis occurs less frequently but poses serious risks to maternal and infant health.
- Untreated mental health conditions can result in risky behaviors or a lack of engagement in beneficial health practices.
Maternal Mortality in the United States
- The U.S. maternal mortality rate is currently at 23.8 deaths per 100,000 live births, substantially higher than other industrialized nations.
- Rates have risen each year: 17.4 in 2018, 20.1 in 2019, and 23.8 in 2020, indicating a disturbing trend.
- Despite many maternal mortality causes being treatable, a lack of timely diagnosis and treatment contributes to preventable deaths.
Causes of Maternal Mortality
- Other cardiovascular conditions (15.3%)
- Other noncardiovascular conditions (13.3%)
- Severe bleeding (11.1%)
- Heart muscle disease (11.1%)
- Blood clots (9.2%)
- High blood pressure (7.8%)
- Stroke (7.2%)
- Increased focus on hospital care may overlook community-based approaches and existing health disparities.
Historical Context and Trends
- Maternal mortality rates had been on a steady decline due to improved living conditions and health services until stagnating in the late 1990s.
- Rates plateaued at around 14 deaths per 100,000 from 2008 to 2019 but have recently begun to increase again.
- This increase raises concerns about the adequacy of maternity care systems and associated health equity issues.
Racial and Ethnic Disparities
- Black women face a maternal mortality risk three times higher than white women.
- Current ratios: Black mothers 55; Hispanic mothers 18; White mothers 19 per 100,000 live births.
- Disparities are long-standing; in 1915, Black mothers had a maternal mortality ratio of 1,065 compared to 601 for white mothers.
Factors Contributing to Disparities
- Pregnancy-related mortality is 3.2 times higher for Black women and 2.3 times higher for American Indian/Alaska Native women compared to white women.
- Higher education does not shield Black mothers from elevated risks; maternal deaths occur more frequently among educated Black mothers than less-educated white mothers.
- Structural racism and bias within healthcare systems exacerbate these disparities.
Insurance and Healthcare Access
- Women relying on Medicaid face significant challenges compared to those with private insurance, including less postpartum support and more negative treatment experiences.
- Common issues reported by Medicaid recipients include lack of postpartum visits, inadequate emotional support, and treatment inequities based on insurance status.
Key Takeaways
- Over half of maternal deaths are preventable; emphasis should be on comprehensive postpartum care.
- Maternal health does not end at delivery; ongoing care is critical.
- Importance of listening to patients, validating their concerns, and addressing biases within healthcare systems.
Emergencies in Pregnancy by Trimester
-
1st Trimester
- Common complaints: Bleeding (spontaneous abortion), pain (ectopic pregnancy), infection (septic abortion), nausea/vomiting (hyperemesis gravidarum).
-
2nd Trimester
- Issues include bleeding (spontaneous abortion, placenta previa), pain (round ligament pain, GERD), hypertensive urgency/emergency, cerebrovascular accident (CVA), and hyperemesis gravidarum.
-
3rd Trimester
- Adds concerns: decreased fetal movement, hyperglycemia/DKA, pre-eclampsia/eclampsia (hypertension and fluid shifts), HELLP syndrome, bleeding (placenta previa, placental abruption), leaking (possible rupture of membranes), and pain (UTI, preterm labor).
Anytime Emergencies
- Pregnancy-related emergencies: pulmonary embolism, deep vein thrombosis (DVT), cardiac events.
- Other issues: STIs, viral infections (cold/flu/COVID), interpersonal violence, trauma, gallstones/cholecystitis, appendicitis, pancreatitis.
Hyperemesis Gravidarum (HEG)
- Severe nausea and vomiting in pregnancy leading to persistent vomiting, significant weight loss (over 5%), dehydration, and electrolyte imbalances.
- Caused by human chorionic gonadotropin (HCG); levels peak around 10-12 weeks before declining.
- Treatment: IV hydration and electrolyte replacement, antiemetics (Phenergan, Zofran), and possible hospitalization if conservative measures fail.
First Trimester Bleeding
- Affects 20-25% of pregnancies; 50-75% continue despite bleeding.
- Increased risk of loss with heavy bleeding and cramping; decreased risk if intrauterine gestation with fetal cardiac activity is detected.
- Important protocols: order blood type and Rh factor, administer RhoGAM if Rh negative to prevent immunological complications.
Types of Abortions
- Threatened Abortion: Bleeding present with an intrauterine pregnancy.
- Inevitable Abortion: Visualized pregnancy with cervical dilation, persistent bleeding.
- Incomplete Abortion: Ongoing miscarriage; cervical dilation with retained products needing procedure for completion.
- Anembryonic Gestation (Blighted Ovum): Gestational sac present but no fetal development, often resolving in spontaneous abortion.
Complications of Abortion
- Septic Abortion: Complication due to infection; can be life-threatening and requires broad-spectrum antibiotics and possible surgical intervention.
- Heavy bleeding indicates need for type/Rh crossmatch and IV access.
Ectopic Pregnancy
- A non-intrauterine gestation, posing life-threatening risks due to potential rupture.
- Incidence: 1.5% - 2% of pregnancies, rising due to factors like assisted reproductive technology, tubal surgeries, and increasing incidence of STDs causing tubal scarring.
- Most commonly occurs in fallopian tube (over 93%), with a few cases in uterine cornu.
Normal vs. Ectopic Implantation
- Normal implantation occurs in the uterus 4-6 days post-fertilization in the fallopian tube.
- Ectopic implantation arises from issues like tubal dysmotility or scarring, preventing travel to the uterus, leading to potential rupture and hemorrhage.
Common GYN Concerns in the ER
-
Rash:
- STI causes include HSV, warts, syphilis, HIV/AIDS; ingrown hairs and boils are rarely emergent.
-
Discharge:
- STIs and pelvic inflammatory disease (PID) due to GC/chlamydia are significant; PID may require admission.
-
Post-elective procedures (D&E, D&C):
- Risk of hemorrhage warrants urgent attention.
-
Fistula (post-partum):
- Rarely emergent condition.
-
Pelvic floor dysfunction:
- Organ prolapse considered urgent but not emergent.
-
Pain:
- Dysmenorrhea and ruptured ovarian cysts are rarely emergent; ovarian torsion is a surgical emergency.
- PID with tubo-ovarian abscess (TOA) requires immediate attention.
-
Bleeding:
- Acute bleeding generally managed by outpatient OB/GYN, may be emergent if severe.
- Conditions like anemia from chronic blood loss (uterine fibroids) and complications from OCPs should also be considered.
Ovarian Torsion
-
Definition:
- Rotation of the ovary causes blood flow occlusion, leading to necrosis; critical to act fast.
-
Risk Factors:
- Enlarged ovaries due to weight; pregnancy and history of tubal ligation increase mobility.
-
Age group:
- Predominantly affects reproductive-aged women; rare pre-puberty and post-menopause.
-
Symptoms:
- Acute, severe unilateral abdominal pain, possible nausea/vomiting, elevated WBC, and low-grade fever; may start with intermittent pain.
-
Diagnosis:
- Transvaginal ultrasound with Doppler reveals lack of blood flow and possibly a "whirlpool" sign.
Tubo-Ovarian Abscess (TOA)
-
Description:
- A severe PID infection leading to an inflammatory mass involving the fallopian tube and ovary.
-
Causes:
- Primarily arises from STIs, can become advanced with minimal symptoms.
-
At-risk groups:
- Individuals with STIs or previous history of PID.
-
Symptoms:
- Fever, abdominal/adnexal pain, vaginal discharge, palpable adnexal mass; severe cases may show signs of sepsis.
-
Complications:
- Potential for tubal occlusion, infertility, ectopic pregnancy, and chronic pelvic pain.
Distinctions: Ovarian Torsion vs PID w/TOA
- Similar presentation includes severe unilateral adnexal pain, fever, nausea/vomiting, and elevated WBC.
- Both conditions are GYN emergencies overlapping with symptoms of other surgical emergencies like appendicitis.
Management Protocols
-
Pre-operative preparation:
- Keep patient NPO and establish IV access; start IV fluids and perform preliminary labs including HCG.
-
Consultations:
- Involve GYN and consider general surgery consultation as necessary.
-
Diagnostic Testing:
- Vaginal ultrasound is critical for assessment.
Labor, Delivery, and Postpartum Considerations
-
Postpartum Depression (PPD):
- Affects 1 in 7 mothers; significant risk for maternal morbidity/mortality.
- High recidivism in future pregnancies; rising incidence correlated with increased depression in teenage girls.
-
Postpartum Hemorrhage (PPH):
- Most significant morbidity risk; defined as excessive bleeding within 24 hours of delivery (primary) or later (secondary).
Causes of PPH
-
Uterine Atony:
- Main cause; risk factors include large uterus, prolonged labor, and certain medications.
-
Retained Placenta:
- Failure to confirm completeness of placental delivery can lead to continued bleeding and infection.
-
Trauma:
- Common in rapid or instrumented deliveries; thorough inspection is essential.
Preeclampsia and Related Conditions
-
Pathophysiology:
- Unclear cause leading to hypertension and vascular issues affecting multiple organs.
-
Timeframe:
- Occurs between 20 weeks gestation and 6 weeks postpartum, impacting both maternal and fetal health.
-
Affected organs:
- Include systemic vasculature, placenta, brain, kidneys, and liver; complications may arise if untreated.
