PERINATAL FOLLOW-UPS

1. PERINATAL FOLLOW-UPS

2. Goals • To reduce maternal and perinatal mortality and morbidity rates • To improve the physical and mental health of women and children

3. Importance • To ensure that the pregnant woman and her fetus are in the best possible health. • To detect early and treat properly complications • Offering education for parenthood • To prepare the woman for labor, lactation and care of her infant

4. Schedule for Antenatal Visits The first visit or initial visit should be made as early is pregnancy as possible. Return Visits: • Once every month till 7th month. • Once every 2 weeks till the 9th month • Once every week during the 9th month, till labor.

5. Pattern Of Follow Up Visits • 4 weekly appointments from 20 weeks until 32 weeks • Followed by fortnightly visits 32 weeks to 36 weeks and weekly visits. • The minimum number of ‘visits’ recommended by the Royal College of Obstetricians and Gynaecologists is 5, occurring at 12, 20, 28-32, 36 and 40-41 weeks.

6. BOOKING VISIT: FIRST VISIT

7. Booking History • Past Medical History • Past Obstetric History • Previous Gynaecological History • Family History • Social History

8. Booking Examination • Full Physical Examination: • Cardiovascular • Respiratory Systems • Abdominal • Full Pelvic Examination • Full Breast Examination

9. Examination for most healthy women : • Accurate measurement of blood pressure • Abdominal examination to record the size of the uterus • Recognition of any abdominal scars indicative of previous surgery

10. Measurement of height and weight for calculation of the BMI. Women with a low BMI are at greater risk of fetal growth restriction and obese women are at greater risk of fetal growth restriction and obese women are at significantly greater risk of most obstetric complications, including gestitational diabetes, pre-eclampsia, need for emergency caesarean section and anaesthetic difficulties.

11. Confirmation of the pregnancy • The symptom of the pregnancy • Breast tenderness • Nausea • Amenorrhea • Urinary Frequency • Positive urinary or serum pregnancy test are usually sufficient confirmation of a pregnancy. • Dating Pregnancy, confirms the pregnancy and accurately dates it.

12. Dating Pregnancy • Menstrual EDD • Ultrasonography

13. Menstrual History: A completemenstrual history is important to establish the estimated date of delivery. It includes: • Last menstrual period (LMP). • Age of menarche. • Regularity and frequency of menstrual cycle. • Contraception method. • Any previous treatment of menstrual • Expected date of delivery (EDD) is calculatedbyNaegele’srule

14. Dating by ultrasound Benefits of a dating scan: • Accurate dating women with irregular menstrual cycles or poor recollection of LMP. • Reduced incidence in induction of labor for ‘prolonged pregnancy’ • Maximizing the potential for serum screening to detect fetal abnormalities • Early detection of multiple pregnancies • Detection of otherwise asymptomatic failed intrauterine pregnancy

15. Advice, Reassurance & Education • Reassurance & explanation on pregnancy symptoms: • Nausea • Heartburn • Constipation • Shortness Of Breath • Dizziness • Swelling • Back-ache • Abdominal Discomfort • Headaches

16. Information regarding: • Smoking • Alcohol Consumption • Drugs • Nutrition & Exercise

17. Booking Investigation • Full Blood Count • Blood Group & Red Cell Antibodies • Women found to be rhesus negative will be offered prophylactic anti-D administration at 28 and 34 weeks’ gestation to prevent rhesus iso-immunization and future HDN. • Other possible iso-immunization events, such as threatened miscarriage after 12 weeks’ gestation, antepartum haemorrhage and delivery of the baby, may require additional anti-D prophylaxis in rhesus-negative women.

18. Rubella • Women who are found to be rubella non-immune should be strongly advised to avoid infectious contacts and should undergo rubella immunization after the current pregnancy to protect themselves for the future. • Hepatitis B • Vertical transmission to the fetus may occur, mostly during labour, and horizontal transmission to staff or the newborn infant can follow contact with body fluids. • A baby born to a hepatitis B carrier should be actively and passively immunized at delivery.

19. Human Immunodeficiency Virus • In known HIV-positive mothers, the use of antiretroviral agents, elective Caesarean section and avoidance of breastfeeding reduces vertical transmission rates from approximately 30% to less than 5%. • The Department of Health guidelines now recommend that all pregnant women should be offered an HIV test at booking. • Syphilis

20. 7. Urine examination: asymptomatic bacteriuria is more likely to ascend and cause pyelonephritis in pregnancy. This causes significant maternal morbidity, but also predisposes to pregnancy loss and preterm labour. All women at booking should wither have a midstream urine sent for culture or be tested with a dipstick which recognizes nitrates, the presence of which sensitivity predicts the presence of significant bacteria.

21. 8. Hemoglobin Studies • Toscreenandtreatirondeficiencyanemia • Toscreenthalassaemia and sickle cell disease are usually reserved for women who have an ethnic background and those from the Middle East.

22. 9. Gestational Diabetes • Fasting Blood Sugar • At firstvisit, if > 95 mg/dl, ask for an early oral glucosetolerance test

23. 10. Testsforhigh risk groups • Serum TSH • TORCH tests • Glucosetolerancetests • IndirectCoombs test forRhincompatiblecouples

24. Antenatal complications dealt with in High risk pregnancyunits in collaborationwithrelateddepartments

25. Endocrine(diabetes, thyroid, prolactin and other endocrinopathies) • Miscellaneous medical disorders (e.g. secondary hypertension, autoimmune disease) • Haematology (thrombophilias, bleeding disorder) • Substance Misuse • Preterm labour • Multiple gestation • Teenage pregnancy

26. Content Of Follow Up Visits • General questions regarding maternal well-being. • Enquiry regarding fetal movements (24 weeks). • Measurement of blood pressure (a screen for pregnancy-related hypertensive disorders). • Urinalysis, particularly for protein, blood and glucose: this is used to help detect infection, pre-eclampsia and gestational diabetes.

27. Oedemais common in pregnancy and is mostly an insensitive marker of pre-eclempsia. Oedemaof the hands and face is somewhat more important as a warning feature of pre-eclampsia.

28. Weightgain

30. Abdominal palpation for fundal height: If repeated symphysis–fundal height measurement are made throughout a pregnancy, the detection of fetal growth problems and abnormalities of liquor volume increased.

31. Auscultation of the fetal heart: There is no evidence that this practice is of any benefit in a woman confident in the movements of her baby; however, it provides considerable reassurance and will occasionally detect an otherwise unrecognized intrauterine fetal death.

32. INSTEAD………. • ULTRASONOGRAPHIC evaluation of fetalgrowth, anatomy, amnioticfluidvolume, placenta, cervix

33. From 36 weeks, the lie of the fetus (longitudinal, transverse or oblique), its presentation (cephalic or breech) and the degree of engagement of the presenting part should be assessed and recorded. It is often at this appointment that a decision is made regarding the mode of delivery (i.e. vaginal delivery or planned Caeserean section).

34. 36 – 40 weeks, Non-Stress Test (NST) forhigh risk pregancies (1x/week) • 40 – 42 weeks, Non-Stress Test (NST) (2x /week)

35. At 41 weeks’ gestation, a discussion regarding the merits of induction of labour for prolonged pregnancy should occur. An association between prolonged pregnancy and increased perinatal morbidity and mortality means that women are usually advised that delivery of the baby should occur by 42 completed weeks’ gestation. This will usually mean organizing a date for induction of labour at approximately 12 days past the EDD.
