Mesoderm: Everything else

How many trimesters of pregnancy are there?


Outline time frames

3 trimesters


Trimester 1 = 3 months


Trimester 2 = 3 months


Trimester 3 = 3.5months

What are the female anatomical adaptations to pregnancy

-Reproductive organs become engorged with blood


-Pigmentation of facial skin - known as chloasma


-Uterine enlargement


-Pelvic ligaments and pubic symphysis relax, widen and become more flexible (due to placental production of relaxin --> causes ligaments to relax)


-Weight gain


-Breasts engorge with blood and areolae darken as a result of increased estrogen and progesterone

What are the Metabolic Maternal adaptations to pregnancy

Placenta enlarges and secretes hPL (human placental lactogen) which:


- Promotes growth of the fetus


-Combined with Estrogen and Progesterone, stimulates maturation of breasts for lactation


- Exerts glucose sparing effect in mother causing maternal cells to metabolise more fatty acids and less glucose than normal


Placental also secretes hCT - increases rate of maternal metabolism

What are the maternal physiological adaptations during pregnancy

GI: Nausea until they adjust to elevated progesterone and estrogen, Heartburn, constipation (decreased GI tract motility during pregnancy)


Urog: Increased production & frequencyof urine


Resp: Increased TV and RR, decreased RV, Dyspnoea (later on)


CV: Total body water increases, increased blood volume (by 20-40% by 32nd week), increased CO, Varicose veins (due to uterus pressing on pelvic blood vessels)

Women who are >70yrs who have never had a pap smear or who request one should be screened


May stop age 70yrs for women who have had 2 normal pap smears within the last 5 years

What is the management pathway for HSIL/LSIL result from pap smear?

HSIL - refer for colposcopy


LSIL


>30 yrs and no abnormal smear - offer repeat pap in 6 months or immed. colposcopy


<30 years - repeat pap in 12 months (if normal can return to normal 2 yearly screening, if still abnormal refer for colposcopy)

Explain the process of colposcopy to a patient.

Colposcopy is a procedure done by specialist. Use a speculum to visualise the cervix. Under high magnification, Vinegar sprayed onto the cervix and any abnormal area will stain white. Then iodine solution applied - any abnormal areas will not stain dark brown.


If any abnormal areas, biopsies will be taken, You may need to have another procedures following results.


Follow up: Pap smear + colp @ 6 mnths, Pap smear + HPV test @ 12mnths, Pap smear + HPV test @ 12mnths


Risks: Infection & Bleeding

2) Spec = closed os, pain, bleeding


3) Ix = Spec and examination, Ultrasound (for fetal heart), B-hCG (positive)


4) Resuscitate if shocked, Reassurance and commonly pregnancy will continue, close monitoring (as increased risk of spontaneous miscarriage 50%)

What is an Incomplete miscarriage?


What are the examination/history findings?


What are the investigations?


What id the treatment/management?

1) Where the fetus has deceased and products of conception have only partially been expelled.


2) Spec - os may be open or closed, +/- contractions, ongoing persistent bleeding and pain, +/- shock


3)Ix: Speculum and examination, pelvic USS


4) Admit to hospital, resuscitate if hemodynamic instability, if unstable need to be taken for D&C, if stable, 3 options: 1) expectant management, 2)Misoprostol 400ug 4 hrly for 3 doses, 3) Surgery - Suction curettage/ D&C. Give anti-D if Rh- mother, psychological counselling

What is an inevitable miscarriage?


What are the examination/history findings?What are the investigations?What id the treatment/management?

1) Uterine bleeding + strong uterine contractions that cause dilatation of the cervix - a 'miscarriage in process'


2) Bleeding, severe colicky uterine pains + contractions


3) Speculum exam = os is open (part of conception sag bulging through) + pelvic US (no fetal heart)


4) Admit to hospital, group and hold, Anti-D, Psychological support (further management depends on whether progression to complete or incomplete miscarriage)

What is a complete miscarriage?


What are the examination/history findings?What are the investigations?What id the treatment/management?

1) Bleeding with Complete expulsion of all products of conception


2) Cervical os closed, bleeding and abdominal pain that decreases over 10 days


3) Ix: speculum, pelvic USS = empty uterus, endometrial thickness <15mm


4) Psychological support, Anti D if Rh- mum and after 12 weeks, follow up to see if bleeding has ceased/kept going

What is a Septic Miscarriage?

1) A miscarriage that is complicated by infection


2) Maternal fever, tachycardia, most likely organisms = strep/staph/e.coli, PINK vaginal discharge, tender abdomen and tender uterus


3) High vaginal swab/cervical swab for M/C/S, Blood cultures (if temp over 38.4), Pelvic US


4) Admit, commence broad spectrum antibiotics

What is a recurrent miscarriage?


What are the examination/history findings?What are the investigations?What id the treatment/management?

1) A woman who has had 3 or more successive miscarriages (chances of successful pregnancy are high if had a previous live born)


2) Symptoms of miscarriage


3) Refer for investigation of cause - genetic abnormalities of parents, fetal genetic abnormalities, uterine abnormalities

Placental abruption


Uterine abruption


Bloody show


Hemorrhoids/Hematuria


Cervicitis/ Vaginal infections


Trauma


Coagulation disorder

Wha is the general management of APH?

1. Asssess hemodynamic status - if unstable, resuscitate with IV fluids, Oxygen, IV access (BP needs to be over 100mmHg systolic)


2. Hx and Examination (no bimanual!!)


3. Blood group and hold


4. Clotting screen


5. Catheterise - keep over 30mL/hr


6. TV Ultraousnd - to locate placenta


7. CTG monitoring of fetus


8. Anti D in Rh- women

What is placenta praevia?


What are the risk factors?

When the placenta is implanted in the lower uterine segment and lies below the fetal presenting part/leading pole of the fetus




Risk factors: Previous placenta praevia, multiparity, previous Cesarean, smoking, advanced maternal age, multiple pregnancy, Uterine abnormalities (e.g. fibroids)

What are the grades of placenta praevia and which grades require mandatory Cesarean section?

Grade 1 - Low lying: <2cms from internal os


Grade 2 - Marginal: Reaches the internal os


Grade 3 - Partial: Partially covering os


Grade 4 - Total: Covering the os (placental praevia major)


Minor = Stage 1 & 2


Major = Stage 3 & 4


Grade 3 & 4 require cesarean section

What are the clinical features of placenta praevia?

- Unprovoked, painless vaginal bleeding (usually begins light --> heavy, bright red)


- Bleeding after sexual intercourse


- Pain 10% have coexisting abruption/uterine contractions


- Fetal heart sounds usually normally


- Can even be asymptomatic - picked up on USS


- Uterus soft, non tenders


- Fetal malpresentation

What are the maternal and fetal risks of placenta praevia?

Maternal


- APH/ PPH


-Placenta acrete


- Cesarean section


- Hysterectomy


Fetal


- Preterm birth


- IUGR


- Congenital - malformations

What are the appropriate investigations for placenta praevia?

1. Transvaginal USS preferred (Transabdominal easiest and safest though) - looks at placental position, volume of liquor, fetal anatomy, biophysical profile of placental


2. Speculum - BIMANUAL CONTRAINDICATED due to risk of rupture of placenta


3. CTG - fetal monitoring



What is the management/treatment for placenta praevia?

1. Hospital admission


2. IV access - 2 large bore IV cannulas, saline, group and hold, antibody screen


3. Localise placenta via USS


4. If severe (massive blood loss/fetal distress) - immediate delivery by cesarean section may be necessary


5. Need cesarean section for delivery - 37-38 weeks


6. Anti D - if mother Rh-


7. Give steroids if <34 weeks (accelerates fetal lung maturity)


8. If over 3cm from os, can attempt vaginal birth

What are the following conditions?


1. Placenta accreta


2. Placenta increta


3. Placenta percreta



1. When the placenta (chorionic villi) attach to the myometrium (instead of just endometrium)


2. When chorionic villi invade into the myometrium


3. When the chorionic villi invade through the myometrium

What is placental abruption?


What are the 2 types?

1. Separation of a normally situated placenta from the lining of the uterine wall


2. Concealed and Revealed


3. Risk factors: previous placental abruptuion, hypertension, pre-eclampsia, multifetal gestation, choriomanionitis, smoking, cocaine/amphetamines, external trauma, increasing age/parity


3.Features: Large PV bleeding (70-80%) leading to hypovolemic shock, constant abdominal/pelvic pain and contractions (hallmark feature is PAIN), premature onset of labour, 'woody hard' uterus (painful, tender, tense), fetal distress on CTG

What are the Ix for placental abruption?


What is the management?

- CLINICAL DIAGNOSIS


- Ultrasound is NOT a method for diagnosis (negative USS does not exclude)


Mx: -Admit to hospital, IV access, Cross match/group and hold, DIC screen - IV fluids/resuscitation


- CTG


- Anti-D (if negative mother)


- +/- emergency Cesarean section (if already in established labour - can go ahead but have low threshold for Cesarean)


- Anticipate PPH!! - have blood ready for transfusion

What is uterine rupture?


What are the risk factors?


What are the clinical features?

1) Separation of an old uterine incision with rupture of the fetal membranes resulting in communication between the uterine cavity and peritoneal cavity


2) RF: Hx of trauma, previous cesarean section, previous uterine surgery, grand multiparity, forceps/shoulder dystocia


3 ) Features: vaginal Bleeding, abdominal/pelvic pain and tenderness disappearance of uterine contractions, absence/deterioration in fetal heart rate, easily palpable fetal parts, sudden fetal distress during labour

What are the investigations for Uterine Rupture?


What is the appropriate management for uterine rupture?

1. Ultrasound


2. Mx: Emergent laparotomy +/- hysterectomy (based on extent of rupture)

What is vasa previa?
What are the investigation(s)?


What is the management?

Where the fetal vessels from the placenta cross over the entrance to the birth canal (vessels can tear during labour)


Ix: TV USS


Mx: Elective cesarean section (if detected before labour)

What are the differential dx for hypertension in pregnancy?




What is the definition of hypertension in pregnancy?

Chronic hypertension (if present <20 weeks gestation(


Pre-eclampsia


Eclampsia


Gestational Hypertension


Chronic hypertension with superimposed pre-eclampsia




Hypertension in pregnancy: Greater or equal to 140/90mmHg on at least 2 readings a few hours apart

What is chronic hypertension in pregnancy?

Hypertension that persists and is present before pregnancy or within the first 20 weeks gestation




Twice the risk of developing pre-eclampsia


High risk pregnancy

What is the management of chronic hypertension in pregnancy?

1) Antihypertensives :


- Use methyldopa or beta blocks (atenolol) or Ca channel blockers (nifedipine)


- AVOID ACE inhibitors (teratogenic!!)


- Avoid diuretics - decrease placenta volume/placental blood flow


2) Increased antenatal visits - to monitor for significant rise in BP or proteinuria --> pre-eclampsia


3) If fetus fails to grow or maternal hypertension deteriorates = DELIVER

What is gestational hypertension?

1) Hypertension that arises after 20 weeks gestation (usually 36-37weeks) and do not have any other features of pre-eclampsia (no proteinuria ect)




At risk of developing pre-eclampsia


If it occurs before 30 weeks, likely to progress to pre-eclampsia


Usually resolved by 3 months post partum

What is the management of gestational hypertension?

1) Careful surveillance


2) Ambulatory BP monitoring at home


3) If exceeds 140/90 --> commence hypertensive therapy (Methyldopa 250-1000mg bd)


4)If BP >160/110mmHg admit to hospital


5) Prophylactic aspirin therapy if 'high risk' of developing pre-eclampsia

What is the threshold for commencing anti-hypertensive therapy in pregnancy ?

BP of 140/90mmHg

What is pre-eclampsia?

Multisystem disorder in pregnancy characterised by Hypertension - greater/equal to 140/90 onset after 20 weeks plus 1 or more of the following:


Proteinuria


Oedema


Renal insufficiency/involvement


Liver dysfunction - raised transaminases, RUQ pain


Neurological problems - severe headaches ect


Hematological disturbances - Thrombocytopenia ect


Fetal growth restriction


Pulmonary oedema


Placental abruption





What is HELP Syndrome?

Complication/variant of Pre-eclampsia


Often develops in a woman with hypertension in pregnancy




H - Hemolysis


EL - Elevated liver enzymes


LP - Low platelet count

Placental abruption


Neurological deficits


Aspiration pneumonia


Pulmonary oedema


Cardio-pulmonary arrest


Acute renal failure


Maternal death



What are the clinical features of eclampsia?

Convulsions


Coma


Often preceded by disorientation stage


Can occur antepartum, intrapartum and post partum

What is the management of eclampsia?

Goals of management are to: - Control fits by relieveing vascular spasm, Reduce BP to prevent cerebral hemorrhage, Delivery of fetus


- ABC,


- Control convulsions with magnesium sulphate (4g IV infusion) - monitor RR (stop if RR<14) and plasma magnesium (stop if >3.5)


- Delivery after control - >34 weeks can have normal, <34wks give steroids and cesarean section


- Treat complications


May need HDU/ICU admittance


- Give antihypertensives - Hydralizine IV
