  4. Opportunities for preconception counseling occur ; Premarital examination and testing Contraception counseling Evaluation for sexually transmitted disease or vaginal infection After a negative pregnancy test Presents for a periodic health examination

  5. Barriers to preconception counseling Unplanned pregnancy Risk factors for adverse outcome that cannot be modified(maternal age or genetic history) Financial issues Inadequate training of health care providers and long waiting times for appointments

  6. Chief Complaint History of Present Illness Past Medical History Medications Family History Social History Physical Exam Assessment and Plan Typical Patient Visit

  7. Chief Complaint/HPI • Ask about reproductive life plan • ½ pregnancies in the US are unintended • Remember that any one who is menstruating and having sex can get pregnant. • Help patients and partners develop a plan, and help them implement it

  8. Past Medical History • Infections • Immunizations • Previous Pregnancies • Chronic Diseases

  9. Infection History • TORCHES • Toxoplasmosis: increased risk with handling raw meats, cat litter • Other: Listeria, Coxsackie virus, Parvovirus • Rubella • CMV: seroconversion highest risk for day care workers caring for 12-36 month old children • Hepatitis B,HIV, Herpes viruses • Syphilis

  10. Immunizations • TORCHES: Rubella, Hepatitis B, Varicella • Tetanus • Pertussis • Flu: If woman expects to be at least 3 months pregnant during flu season

  11. Reproductive History • Pregnancies • Outcome • Perinatal difficulties • Control of chronic diseases during pregnancy

  12. Chronic Hypertension-Maternal Morbidity • Preeclampsia: • 25% of women with chronic HTN • 40% with severe HTN • Renal failure, HELLP syndrome, Eclampsia • Peripartum cardiomyopathy • Exacerbated by increased blood volume, decreased oncotic pressure

  13. Chronic Hypertension-Neonatal Morbidity • 2/3 Preterm delivery • 1/3 Small for Gestational Age • Mortality • 2-4 times above baseline rate for population • Other complications • Placental Abruption • Cesarean Delivery • Intrauterine Growth Restriction

  14. Glycemic Changes during Pregnancy • ENHANCED insulin sensitivity- late first trimester • More hypoglycemia, especially with coexistent vomiting • Increased caloric requirements- 300kcal/day • REDUCED insulin sensitivity- throughout pregnancy • Allows for continuous glucose delivery to fetus, even at fasting state • Increased cortisol, placental growth factor, progesterone, prolactin, human placental lactogen, others

  15. Diabetes-Maternal Morbidity • Ketoacidosis • Develops more rapidly with less severe hyperglycemia than non pregnant patients • Risk factors: new onset DM, infection, poor compliance, antenatal corticosteroids and tocolytics • Preeclampsia • Up to 50% of pts with Diabetes and Nephropathy

  16. Diabetes- Maternal Morbidity • Retinopathy • PROGRESSION of retinopathy due to tight glucose control • Long term risk is not altered by pregnancy • Nephropathy • Risk Factors: baseline creatinine >1.5mg/dL, severe proteinuria

  17. Diabetes-Congenital Malformations • Risk of malformation proportional to HbA1c • Overall double the risk compared to infants born to non-diabetics • 5% risk if HbA1c is 7% • 23% risk if HbA1c is 8.6%

  18. Diabetes-Congenital Malformations • Cardiac: Transposition of great vessels, VSD, Coarctation, Patent Ductus Arteriosis, Situs Inversus • Renal: Ureteral Duplication, Agenesis • Neurologic: Anencephaly, Microcephaly, Neural tube defects • Gastrointestinal: Duodenal atresia, imperforate anus, anorectal atresia • Skeletal: Caudal Regression Syndrome

  19. Diabetes- Neonatal Morbidity • Neonatal hypoglycemia • Transient fetal hyperglycemia leads to β-cell hyperplasia and hyperinsulinemia • Macrosomia • Increased risk shoulder dystocia at delivery • Higher rates of primary cesarean delivery

  27. Others • Nicotine replacement: Patches, nasal spray, inhaler are Class D, gum is Class X • Isotretinoin(Accutane): Class X

  28. Chronic Hypertension- Treatment • No data that treatment of Mild Hypertension will improve maternal/fetal outcomes • Consider stopping/reducing RX in women who become pregnant. • Restart for women with SBP>150-160 or DBP>100-110 1 Ferrer et al. Obst Gynecol 2000

  29. Chronic Hypertension-Treatment • Safe Agents: Class C • Methyldopa • Labetalol • Nifedipine • Some Risk: Class D • Diuretics • Selective beta blockers, during second and third trimesters • Avoid: Class D • ACE-Inhibitors/ARBs

  30. Diabetes-Treatment • Good control BEFORE conception • During Pregnancy • Diet, Exercise, and Insulin therapy • Close Monitoring • Goals: • fasting glucose <95mg/dL • nighttime glucose >60mg/dL • Hemoglobin A1c <6%

  31. Diabetes-Treatment • Insulin therapy • Range from .7-1.2 U/kg/day • Oral Agents: • Glyburide: Class C, but does not cross placenta, comparable to insulin in improving control without evidence of complications • Metformin: Class B • TZDs: Not well studied, Class C

Am J of Obstetrics and Gynecology, 2008

  38. Social Stressors • Emotional abuse • Physical abuse

  41. Physical Exam • Screening for/ evaluation of Chronic diseases • Pulse, blood pressure • Thyroid disease • Hypoxemia • Weight • Oral Care

  42. Obesity • Obesity is defined as BMI of 30-35 kg/m2 • Morbid Obesity is BMI > 35 kg/m2

  43. Obesity- Maternal Morbidity • Gestational diabetes (GDM) • NYC study: women 200-300+ lbs were 4 to 5 times more likely to develop GDM • Preeclampsia • Placental abruption • Cesarean delivery • Even when controlling for macrosomia • Endometritis and wound infections Rosenberg et al. Obstet Gynecol 2003

  44. Obesity-Neonatal Morbidity • Macrosomia • Mount Sinai Study: mean birth weight 83 g (3 ounces) heavier • Increased even when controlling for GDM • Significant increase risk among morbidly obese women who gained >25 lbs during pregnancy • Increased risk NICU stay Bianco, Et al. Obstet Gynecol 1998

  45. Periodontal Disease • Perhaps related to preterm birth • Multiple studies, varying designs/quality • 3 studies: Treatment lead to significant reduction in preterm low birthweight infants, no significant difference in total preterm births • 800 women randomized to tx during pregnancy vs tx postpartum: No difference in preterm birth, low birthweight • Thought to be a marker for excessive local response to bacteria Xiong, X et al.. BJOG 2006; 113:135.

  47. Reproductive Life Plan • Encourage her to talk with partner, develop a plan for more children. • Offer contraception • Consider IUDs, contraceptive implants

  48. Infections/Immunizations • Screen for • Rubella immunity • Syphilis, HIV, Hepatitis B • Vaccinate • Routine: Pneumovax, Flu, Tetanus, Pertussis • Consider Hepatitis B, HPV if risk factors

  49. Chronic Diseases • Screen for • Anemia • Hypothyroidism • Cervical dysplasia • Treat known diseases • HTN • DM • Obesity

  50. Hypertension Treatment • Change Class D/X drugs before pregnancy, Consider Class C • Change ACE-I to labetalol, methyldopa, thiazide, calcium channel blocker • Remember that BP may drop early in pregnancy, pt may need to stop medications initially
