OB/GYN pregnancy loss

Clinical Perspective vs. Basic Science: The discussion focuses purely on clinical application rather than theoretical basic science.
Patient Counseling and Authority: - Providers must acknowledge the influence of external information sources on patients, including YouTube, AI, TikTok, and well-meaning or ill-meaning relatives. - Relatives often render opinions on how a loss could have been prevented, which can instill guilt in the patient. - Clinicians hold a significant level of authority (especially those with professional credentials). - It is critical to explicitly state to the patient what did NOT cause the loss to alleviate guilt. Statements should include: "It is not the cheeseburger," "It is not the scary movie," "It is not the fight you had with your best friend," and "It is not the heavy suitcase you picked up." - The medical reality is often simply that "it happened because it happened." - The information provided by the clinician will be weighted more heavily by the patient than the opinions of older relatives or social media.

Legislative Awareness: Clinicians must keep up-to-date with state laws regarding abortion restrictions and bans.
Purposes of Legal Knowledge: 1. To protect the patient. 2. To protect the provider from legal repercussions, including severe penalties such as the death penalty in some current contexts.
Terminology and Language: - Abortion: Primarily a medical term referring to the loss of pregnancy or termination before $20$ months. Note: The speaker likely meant $20$ weeks, but the transcript states months. - Miscarriage: A term frequently used by patients. The speaker dislikes the term because it implies the patient "did something wrong" or failed to "carry it the right way" (akin to a "miscarriage of justice"). - Preferred Term: "Pregnancy loss" is preferred to avoid the negative connotations of "miscarried."

Viability in Obstetrics: Used in two ways: 1. A pregnancy that is currently continuing and growing. 2. A pregnancy that has reached a gestational age where it could survive outside the womb.
Non-Viable Intrauterine Pregnancy: Defined as a pregnancy within the first $13$ weeks (first trimester) where: - There is a gestational sac but no embryo. - There is a gestational sac with an embryo but no cardiac activity.
Epidemiology and Risk Factors: - Advanced Maternal Age (AMA): Defined as an individual who is $35$ or older or will be by their due date. Risk increases significantly at ages $45$ to $48$ . - Advanced Paternal Age: Generally considered between $40$ and $50$ , though not as strictly defined as maternal age. - Prior Pregnancy Loss: Increases the risk of subsequent loss. - Chemical Pregnancy: A very early loss where a pregnancy test is positive but the pregnancy fails almost immediately. - Chromosomal Anomalies: Account for approximately $50\%$ of all losses. Trisomies are the most common anomaly. - Environment Factors: Alcohol use, smoking, caffeine consumption, and exposure to toxins/pollutants.

Pregnancy loss can be viewed as a continuum where a patient may progress through several stages:

Incidence: Affects approximately $25\%$ of people in the first trimester.
Symptoms: Vaginal bleeding (can range from spotting to moderate) and mild lower quadrant tenderness.
Physical Exam: Positive urine pregnancy test, blood in the vaginal vault, but the internal os is closed.
Uterus: Size matches the expected gestational age.
Workup: - Urine pregnancy test (if negative, no further workup for loss is needed). - Transvaginal Ultrasound: Looking for the gestational sac or cardiac activity. - Quantitative hCG: If hCG is $1,500\,mIU/mL$ , a sac should be visible; at $8,000\,mIU/mL$ , a more developed embryo or cardiac activity is expected.
Management: Reassurance, but not a guarantee of safety, as these pregnancies have a higher risk of loss.

Definition: Occurs before $20$ weeks; involves rupture of the amniotic sac and a dilated cervix.
Clinical Reality: Once membranes rupture and the os is dilated, the pregnancy cannot be saved.

Definition: Partial passage of products of conception (POC), usually placental tissue, before $20$ weeks.
Symptoms: - Heavier vaginal bleeding (increases with gestational age). - Severe pain/cramps. - History of passing tissue.
Clinical Signs of Severe Hemorrhage: Patient may be syncopal, have palpitations, dizziness, or headache.
The "Salsa Rule": If a patient is soaking more than two pads an hour for more than two hours, or if they "bleed into their shoes," it is time to call the blood bank and prepare for transfusion.
Physical Exam: Internal os is open. POC may be seen at the os.
Workup: CBC, blood typing, cross-matching, and ultrasound.

Definition: All products of conception have passed.
Symptoms: History of heavy bleeding and pain that has since subsided.
Physical Exam: Internal os is closed. Minimal tenderness. High possibility of blood in the vault but no active hemorrhage.
Management: Follow hCG levels until they reach zero ( $0$ ); this can take several weeks.

Definition: Death of the embryo without symptoms (no bleeding or pain yet).
Diagnosis: Uterus may feel smaller than expected; hCG levels plateau or drop; ultrasound shows no cardiac activity.

Approximately $10\%$ of the population is Rh negative; $90\%$ is Rh positive.
Rh-negative patients must receive Rho(D) immune globulin (RhoGAM) if they experience a loss to prevent the formation of antibodies against fetal RBCs.
Current protocol: Administered to all Rh-negative patients experiencing a loss at or after $12$ weeks of gestation.

Expectant Management: "Wait and see." About $80\%$ resolve on their own, but the timeline is unpredictable.
Medical Management: Used if the gestational sac diameter is less than $2\,cm$ . - Misoprostol: $800\,\mu g$ orally or vaginally to cause uterine contractions. Works within $3$ to $4$ hours. - Mifepristone: A selective progesterone receptor inhibitor that blocks progesterone, ending the pregnancy and helping empty the uterus. - Pain Management: Ketorolac (Toradol) is often effective; morphine may be required if Toradol fails.
Surgical Management: Indicated if the sac is greater than $2\,cm$ or if the patient is hemorrhaging. - Manual Vacuum Aspiration (MVA): Can be done in an ER or treatment room; less painful than suction curettage. - Suction Curettage: Performed in the Operating Room. Involves a cannula and vacuum. - Risks: Oschmann syndrome (Asherman's syndrome) — scar tissue in the uterine cavity from surgical trauma. - Hospital Dynamics: Hospitals often prefer OR procedures for billing purposes ( $15$ -minute blocks). - Post-Op: Doxycycline is often given to prevent infection; follow-up on pathology is mandatory.

Definition: Infection of the uterine cavity and its contents.
Pathophysiology: Enhanced by pregnancy physiology (high cardiac output, increased uterine perfusion, altered immune system).
Causative Organisms: Clostridium species (distinctive smell), Group A Strep, St
