Maternal health Study Guide

📖 Core Concepts Maternal health – health of women during pre‑conception, pregnancy, childbirth, and postpartum. Maternal Mortality Ratio (MMR) – deaths of women from pregnancy‑related causes per 100 000 live births. Severe Maternal Morbidity (SMM) – life‑threatening complications (e.g., hemorrhage, eclampsia) requiring intensive care. Skilled birth attendance – delivery assisted by a trained doctor, nurse, or midwife able to manage normal birth and recognize complications. Antenatal care (ANC) – minimum four visits that include physical exams, labs, nutrition, education, and ultrasound. Post‑partum period – first six weeks after delivery; critical for detecting hemorrhage, infection, hypertension, and mental‑health problems. Birth spacing – interval of ≥ 18 months between a live birth and the next conception improves outcomes for mother and child. --- 📌 Must Remember Global burden (2017): 295 000 maternal deaths; 99 % occur in low‑/middle‑income countries. Leading direct causes: severe bleeding (post‑partum hemorrhage) and obstructed labour. Key indirect causes: anemia, malaria, HIV, chronic hypertension, diabetes. Risk multipliers: poverty, geographic remoteness, low education, racial/ethnic minority status. Nutrition: daily iron + folic acid prevents anemia, low birth weight, neural‑tube defects. Low‑dose aspirin (< 150 mg) before 20 weeks for women at high risk of pre‑eclampsia. Breastfeeding ≥ 6 months cuts infant infection, obesity, asthma, type 1 diabetes and improves maternal glucose, lipids, BP. Post‑partum depression prevalence: 10–15 % globally; screen at WHO follow‑up visits (day 3, day 7‑14, 6 weeks). Target SDG 3 (2030): MMR < 70/100 000 live births; no country > 2× global average. --- 🔄 Key Processes Antenatal Care Visit Checklist Weight & blood pressure → detect hypertension. Hemoglobin → screen anemia. Urine dipstick → protein, glucose. Ultrasound @ 24 weeks → fetal growth, anomalies. Education on nutrition, warning signs, birth‑plan. Management of Post‑partum Hemorrhage (PPH) Uterine massage → stimulate contraction. Oxytocin 10 IU IV/IM → first‑line uterotonic. If bleeding persists → give methylergometrine or misoprostol, consider balloon tamponade, then surgical intervention. Screening for Post‑partum Depression Administer EPDS or PHQ‑9 at day 7‑14 and 6 weeks. Score ≥ 10 → refer for counseling (nurse‑midwife or tele‑mental‑health). Family‑Planning Counseling Flow Assess desire for future pregnancies → discuss timing (≥ 18 months). Offer contraceptive options (long‑acting reversible, barrier, hormonal). Provide education on correct use & side‑effects. --- 🔍 Key Comparisons Skilled birth attendance vs. Traditional birth attendant Skilled: can manage normal delivery, detect complications, perform emergency obstetric care. Traditional: limited ability to intervene; higher maternal mortality risk. Pregestational diabetes vs. Gestational diabetes Pregestational: present before conception; higher risk of congenital anomalies, pre‑term birth. Gestational: develops during pregnancy; main risk is macrosomia & later maternal type 2 diabetes. Low‑dose aspirin vs. No prophylaxis for pre‑eclampsia Aspirin: reduces pre‑eclampsia incidence by 10‑15 % when started < 20 weeks. No prophylaxis: higher chance of severe hypertension, pre‑term delivery. Breastfeeding (HIV‑negative) vs. Formula feeding Breastfeeding: maternal metabolic benefits, lower infant infection risk. Formula: higher cost, increased infection risk, no maternal health benefit. --- ⚠️ Common Misunderstandings “All anemia in pregnancy is iron deficiency.” – Anemia can also stem from malaria, chronic disease, or vitamin B12 deficiency; treat accordingly. “If a woman takes any amount of alcohol, the baby will have FAS.” – Risk is dose‑dependent; complete abstinence is safest, but low‑level exposure carries lower risk. “Post‑partum depression is just “baby blues.” – Baby blues resolve within 2 weeks; depression persists > 2 weeks, impacts functioning, and requires treatment. “Vaccines are unsafe in pregnancy.” – Tetanus and influenza vaccines are recommended and safe; they protect mother and fetus. --- 🧠 Mental Models / Intuition “Three‑hit model of maternal death”: 1️⃣ Risk exposure (poverty, chronic disease), 2️⃣ Barrier to care (cost, distance), 3️⃣ Complication (hemorrhage, eclampsia). If any one component is removed, mortality risk drops dramatically. “Pregnancy as a stress test”: complications that appear during pregnancy (e.g., hypertension) often predict future cardiovascular disease—treat now, prevent later. --- 🚩 Exceptions & Edge Cases Low‑dose aspirin contraindicated in women with aspirin allergy or active peptic ulcer disease. HIV‑positive mothers: breastfeeding is recommended only when antiretroviral therapy is optimal and alternatives are unsafe; risk of transmission < 5 % with proper treatment. Obesity (BMI ≥ 30): weight‑gain recommendations differ (≈ 5–9 kg total gain). Rural remote areas: tele‑health can substitute for in‑person ANC for routine monitoring, but emergency obstetric care still requires physical facilities. --- 📍 When to Use Which Subsidized health‑care vs. No subsidy – Deploy subsidies in low‑income settings where out‑of‑pocket costs are the primary barrier to ANC and skilled delivery. Group prenatal care (Centering Pregnancy) vs. Standard individual visits – Use group model for populations with high pre‑term birth rates; it reduces pre‑term birth by 33 %. Digital health monitoring vs. Face‑to‑face only – Choose mobile‑app monitoring for geographically isolated pregnant women to improve appointment adherence. Buprenorphine vs. Methadone for opioid‑dependent pregnant women – Prefer buprenorphine for better neonatal outcomes and lower maternal complications. --- 👀 Patterns to Recognize “Late ANC + anemia + malaria” → high risk of low birth weight and maternal death in Sub‑Saharan Africa. “Black or Indigenous race + chronic hypertension + limited insurance” → triple increase in pregnancy‑related mortality in the U.S. “Post‑partum hemorrhage + lack of skilled attendant → most common direct cause of death in low‑income settings. “Maternal smoking + low socioeconomic status → cluster of outcomes: pre‑term birth, SIDS, childhood cancers. --- 🗂️ Exam Traps Distractor: “Maternal mortality is mainly due to indirect causes such as malaria.” – Trap: Direct causes (hemorrhage, obstructed labour) account for the majority of deaths. Distractor: “All pregnant women should gain 25 kg.” – Trap: Recommended gain (11–16 kg) applies to normal‑BMI women; obese women have lower targets. Distractor: “Breastfeeding is contraindicated in all HIV‑positive mothers.” – Trap: With effective ART, breastfeeding is permissible and reduces infant mortality. Distractor: “One antenatal visit is sufficient if the ultrasound is normal.” – Trap: Minimum four visits are required to monitor evolving risks. Distractor: “Post‑partum depression resolves without treatment after 4 weeks.” – Trap: Persistent symptoms > 2 weeks constitute clinical depression needing intervention. ---
