Pregnant female with hypertension + proteinuria + edema + malar rash & positive ANA titer(to differentiate preeclampsia from SLE) = is suspicious of SLE which frequently causes glomerulonephritis which lead to :
Proteinuria
Hematuria
RbCs cast
MgSo4 toxicity :
- Pregnant female + was treated by MgSo4 for severe preeclampsia & eclampsia after hours of treatment she developed : 1- Depressed tendon reflexes (earliest sign).
2- Respiratory depression (second sign).
The most appropriate next step is: Stop MgSo4 & give calcium gluconate.
Hypertension before 20 weeks without protienuria, either :
1- Chronic hypertension occurred before pregnancy (U/S reveals normal gestaional sac) 2- Hydatiform mole U/S reveals "snow storm appearance".
Hypernatremia + Hypokalemia Hyperaldosterenism.
Follow up for protenuira & higher BP if occurred it's : chronic HTN with superimposed pre-eclampsia.
Hypertension is most serious risk factor of : Placental abruption / IUGR / Oligohydraminos/Preterm labour. Risk Factors :
-
Uncontrolled DM
Placenta previa
Uterine atony
Posterm pregnancy
Macrosomia
Prior C.S.
-Multiparity.
Multiple gestation.
Maternal age is old.
- Post-partum hemorrhage - Uterine distention: Multiple gestation , polyhydraminos.
Repeated post-term pregnancies increase risk.
Hellp syndrome
- Triad of :
Thrombocytopenia (low platelet count) .
Microangiopathic hemolytic anemia (↑ indirect bilirubin & RBCs fragments on blood smear)
Increased liver enzymes in a patient with preeclampsia (mild hypertension & mild proteinuria) is defined as HELLP syndrome.
The most appropriate next step in management in :
Induce labor immediately :
In women beyond 34-weeks (fetal lungs are mature).
OR presence of signs of fetal or maternal deterioration.
If below 34 weeks depends on the state of the mother & the fetus: a- Any deterioration : requires Stabilization + Delivery.
b- BUT if fetal well-being is ascertained + mother is stabilized Dexamethasone & delivery :
After 34 weeks or
When fetal lungs become mature.
Mild coagulopathy correct spontaneously after delivery.
Platelets transfusion is needed only when there is advanced coagulopathy.
Hemolytic uremic syndrome : |
|
Acute fatty liver of pregnancy (AFLP) : |
Causes : Acute hepatic failure, in the third trimester or early post-partum period. (Prolonged PT , PTT + moderate elevation transaminases level.) |

Gestational diabetes
Screening test 1h 50-g Oral Glucose Challenge Test (OGCT)
Screening should be performed between 24 to 28 weeks.
Screening is advised at the first prenatal visit in pregnant women with risk factors.
Without regard to time of day or time of last meal (no fasting state is needed):
Plasma glucose level is measured 1 hour after a 50-g glucose load
Normal Value : < 140 mg/dl
Abnormal Value: >= 140 mg/dL identifies 80 % of all women with gestational diabetes.
- An abnormal screening GCT is followed with a diagnostic : 3-hour 100-g oral glucose tolerance test.
Diagnostic test 3h 100-g oral glucose tolerance test (OGTT)
After an overnight fast , a fasting blood sugar (FBS) is drawn :
If FBS > 125 mg/dl , indicates overt diabetes mellitus No further testing is performed
If FBS < 126 mg/dl Administer a 100-g glucose load, and check glucose levels hourly for 3 hours.

If two or more abnormal values : Patient is diagnosed with GDM
If only one value is abnormal :Impaired glucose tolerance
Treatment :
First treated by: trial of diet control. aim of fasting glucose is : 75 – 90 mg/dl.
If not responding (fasting > 90 mg/dl): most appropriate step is : Insulin therapy (not continuing the diet control)
The baby at risk to be born with :
3)
Hyperviscosity ( due to polycythemia)
Hypoglycemia ( due to high baseline insulin in fetus) 2) Hypocalcemia ( due to PTH suppression)
4) hyperbilirubenemia ( due to breakdown of RBCs)
Hyperemesis Gravidarum :
is a severe form of vomiting usually begins between 4 and 10 weeks (if they begin after week 10 or do not resolve by week 20, then another etiology should be suspected.)
While it can be managed successfully with supportive therapy (fluids and nutrition) and generally resolves on its own by mid-pregnancy Other causes of severe vomiting during pregnancy must be ruled out :
Gestation Trophoplastic Disease (hydatidiform mole & choriocarcinoma) is one disease to consider in such cases.
The classical clinical triad for hydatidiform mole :
Enlarged uterus,
Hyper emesis
Markedly elevated beta HCG ( >100,000).
The most appropriate initial next step in evaluation of severe vomiting during pregnancy is :
measuring quantitative B-hCG levels.
If it is markedly elevated Ultrasound should then be performed (to exclude molar disease !)
Remember that :
Some degree of nausea & vomiting affect 50 – 90% in pregnant females BUT In hyper emesis gravidarum women have :
Persistence of vomiting
loss of >= 5% of Pre-pregnancy weight 3) Presence of ketonuria.
Mild increase in ALT, AST/bilirubin/amylase , lipase (from salivary gland due to vomiting) The differential dx includes:
1- Pyelonephritis / 2- GTD / 3-Gastroenteritis / 4- Hepatobiliary disease.
-
Viral Hepatitis
- Presents with: fever+ Rt upper quadrant pain . - More dramatic increase in AST , ALT.
DKA
anion gap metabolic acidosis
This patient instead presents with: HCO3 , suggesting alkalosis from vomiting.
Presence of urine ketones is due to starvation rather than insulin deficiency.
Molar pregnancy
- Presents with: abnormal high level of B-hCG + abnormal U/S
Hyperthyriodism
- Can present with hyperemesis BUT with : tachycardia + tremors + diarrhea.
Prolonged labor :
Women with prolonged labor ?!
1) Check for adequate uterine contractions 2-3 min. lasts 45-60 second.
- If no adequate contractions : give IV Oxytocin.
2)
Assess cervical dilatation (in first
stage):
- Arrest of cervical dilatation : >= 2 hours for primi & multi TTT due to cephalopelvic disproportion ( maternal
3) Assess fetal descent (in 2 nd stage) : pelvis abnormality as: prominent ischial spines):
Arrest of descent : < 2h for primi / < 1h for multi Low transverse C.S
(+ 1h if epidural anesthesia)
Pre-term labor :
Uterine contractions >= 4 per 20 min. + cervical changes / after 20 weeks and before 37 weeks.
Treatment : Depends on Date of gestation + Morbidities to mother to fetus :
1) If normal labor Gestational age between 24 & 34 weeks give tocolysis to maintain pregnancy for at least 48 h. to allow administration of systemic corticosteroids decrease risk of RDS.
In acute pre-term labor , bed rest and tocolysis are continued as long as possible with a long term goal of reaching 34-36 weeks GA.
2) If the fetus is distressed with repetitive late deceleration indication of : Ceasrean section.
Because he is not likely to withstand the stress of vaginal labor.
Should allow spontaneous labor IF preterm labor & by U/S there is severe congenital anomaly incompatible with life as : Bilateral Renal Agenesis decrease AF Lung hypoplasia (can't live outside uterus).
Preterm Premature Rupture of Membranes (PPRM) : diagnosed clinically as gush or leakage of fluid.
The most important complication : pulmonary hypoplasia.
-
If pregnancy < 34 weeks GA + L/D ratio is < 2.0 most important next step is : betamethasone.
-
If pregnancy >34 weeks GA Delivery is usually recommended.
No tocolysis is needed if there is not uterine contractions.
AF index is normally ( >5 & <25 ) amnioinfusion is sometimes used in oligohydraminos.
As long as Non-stress CTG is normal NO C.S is indicated.
Normal AF pH is : 7.0 – 7.5
Normal vaginal pH: 3.8 – 4.5
More neutral pH of the fluid described in this patient indicates it's of amniotic origin.
The
most appropriate next step in management is : Penicillin
prophylaxis.
Chorioamnionitis :
should be suspected in mothers presenting with prolonged or premature rupture of the membranes + fever + any of the following findings:
Maternal tachycardia ( > 100/min),
F etal tachycardia ( > 160/min) is a sign of maternal infection NOT fetal distress ! 3- Maternal leukocytosis (> 15,000/mm3),
Uterine tenderness
foul smelling amniotic fluid.
Treatment :
1- First intervention is to tx the mother with broad spectrum antibiotics since it is : polymicrobial infection :
- Clindamycin IV & - Gentamicin IV.
2- Concomitantly with immediate delivery of the fetus :
A) If in question is having regular uterine contractions oxytocin administration & vaginal delivery. B) If in question there fetal distress C.S
Prolonged (postterm) pregnancy :
is defined as any pregnancy at or beyond 42 weeks gestational age measured from the last menstrual period.
Management with either : 1) Induction of labor in favorable cervix.
2) Expectantly in unfavorable cervix.
Twice weekly monitoring with ultrasound is required to evaluate for oligohydramnios in postterm pregnancies because amniotic fluid can become reduced within 24 to 48 hours.
Oligohydramnios in these cases is defined as :
No vertical pocket of amniotic fluid greater than 2cm or - an AFI of 5cm or less.
Intrauterine Fetal Demise (iufd) :
Fetal death after 20 weeks and before onset of labour (( SUSPECTED BY ABSENCE OF FETAL MOVEMENTS )) - Next most appropriate test used to confirm diagnosis is : Real-time U/S is more reliable tool which shows: absence of fetal movement & cardiac activity.
If confirmed , Next step Coagulation profile to detect DIC ( due to release of thromboplastin from placenta to maternal blood) - Diagnosis :
Fibrnogen value in low normal level ( e.g 160 with N.level: 150 – 450 mg/dl ) + Platelets in low normal value (<150,000) are early sign of DIC induction of labor , is most appropriate next step.
Especially if associated with : Platelet count + PT , PTT + Fibrin splits products.
Management :
1) If any coagulopathy is suspected The most appropriate step is : Induction of labour.(without delay)
-
Fresh Frozen Plasma
If :
1- Coagulation profile is profoundly abnormal (fibrinogen < 100 mg/dl) 2- If DIC or hemorrhage is evident.
Platelet transfusion & plasminogen replacement
If :
1- Coagulation profile is profoundly abnormal (fibrinogen < 100 mg/dl)
C.S
Vaginal Delivery is sufficient to decrease risk of DIC C.S will increase risk of surgery complications
Expectant Treatment
Not suitable if low normal level of fibrinogen and platelets will develop DIC.
2) If Coagulation profile is normal
Discuss need for delivery & review options for vaginal versus C.S.
Watchful expectancy labor occurs spontaneously in 80% of cases within 2-3 weeks of IUFD.
Induction of labor, either vaginal versus C.S.
-
Should have immediate induction of labor
It's not necessary as ifcoagulation profile if normal as patient is not in immediate danger
Recommend C.S as soon as possible
- It's not necessary as births of term infants are routinely done in women following C.S - The delivery of 30 week IUFD vaginally may possible ( if her cervix is favorable is the question) and would avoid risks of operation.
Autopsy of the fetus & placenta |
should be performed after 1st episode of IUFD , in order to prevent , if possible , a recurrence of the same issue in subsequent pregnancies.
There is 1 – 8% risk of recurrent still birth in mothers who have previously experienced IUFD.
Serial B-hCG monitoring is indicated if there suspected molar pregnancy.
Serial fibrinogen testing is indicated to detect DIC if IUFD is managed expectantly
Fetal Growth Restriction (FGR):
Smoking cessation : is the single most prevalent preventable cause of IUGR in the united states which have 3 – 4 fold increase risk of having a growth restricted infant.
FGR is suspected when there is at least 3 cm less than the actual gestation age in weeks ( e.g. GA: 30 weeks and fundal height is: 26 cm )
-
Symmetrical
Asymmetrical
Insult to the fetus occurs
Growth of both head & body is defici
< 28 weeks .
ent
Insult to the fetus occurs
Normal head size & reduced circumference.
> 28 weeks .
Abdominal
- Typically the result of fetal defects su anomalies genetic anomalies or early infections (TORCH).
ch as genetic
congenital
Results from fetal redistribution of blood flow to vital organs ( such as the brain, heart, placenta) as the expense of less vital organs (abdominal viscera)
Maternal factors such as HTN, hypoxemia, smoking, vascular disease and toxic esposures.
Asymmetric has better prognosis than Symmetric
Abdominal circumference is the most reliable index for estimation of fetal size because: it is affected in both symmetric and asymmetric fetal growth restriction.
Biparietal diameter will be :
Normal or close to normal in asymmetric FGR as blood is preferentially shunted to supply the fetal brain Decreased, in symmetric FGR.
Femoral length : Used to estimate fetal size BUT as not accurate as AC.
E arly pregnancy bleeding :
Maintenance of airway , breathing , circulation is always first priority in any patient came to ER with antepartum hemorrhage Most appropriate next step is: obtain venous access with 2 large bore cannulas (Hemodynamic resuscitation) in any patient hemodynamically unstable " Hypotension / tachycardia / cold exteremities
Ectopic Pregnancy : ( presents with unilateral adenxal tenderness + normal vital signs"non-ruptured" )
Patient present with +ve pregnancy test 3 differential diagnosis :
-
Early viable intrauterine pregnancy
Ectopic pregnancy
Non-Viable intrauterine pregnancy (complete abortion)
Initial test is U/S if undetermined : next step is serial B-hCG measurements :
Doubling every 48 hour
Increase at slower rate
Transabdominal U/S detect gestational sac at 6 weeks when B-hCG > 6,500 IU/ml.
Transvaginal U/S detect gestational sac when at 5 weeks when B-hCG 1,500 – 2,000 IU/ml.
If the B-hCG < 1.000 IU/ml both B-hCG & transvaginal U/S should be repeated in 2-3 days (providing the patient is
hemodynamically stable)
Once B-hCG between 1,500 – 6,500 IU/ml next appropriate step is to do : Transvaginal U/S , with 3 possibilities : 1) If revealed intrauterine sac : Normal pregnancy.
If revealed adenxal sac : Ectopic pregnancy
If neither are revealed , next step is serial B-HCG measurements ( repeat B-hCG in 48 hours) :
If doubling every 48 h. suggest : normal pregnancy
Slower rise in B-hCG suggest : abnormal pregnancy.
-
Laparoscopy
- Despite being the gold standard for diagnosis of ectopic B-hCG & transvaginal U/S are enough for diagnosis.
Methotrexate
is used for medical management of non-ruptured ectopic pregnancy providing : 1- Sac < 3.5 cm
B-hCG < 6.000 UI/ml
Non-viable fetus
No history of folic supplementation
Given at 4 – 7 days if no decrease in B-hCG > 15% repeat another course at 11-14 days if no decrease in B-hCG > 15% : Surgry (Salpingectomy / or Salpingestomy).
D & C
- It's indicated when:
1- Pregnancy has been confirmed to be non-viable via serial B-hCG AND 2- Location of pregnancy cannot be determined by : U/S.
Abortion:
Threatened abortion Any hemorrhage occurring before 20th weeks of gestation with : Live fetus + closed cervix. - The most appropriate next step in management is : Reassurance & outpatient follow up.
Inevitable abortion Vaginal bleeding, Colicky lower abdominal (suprapubic ) pain that radiate to back + - Dilated cervix & products of conception can be seen through it.
U/S shows: ruptured sac with absence of fetal cardiac motion.
Most appropriate next step in management is: IV fluids + suction curettage + RhoGAM administration if Rh-ve
Suction curettage is the treatment of choice in inevitable abortion because the pregnancy can't be maintained need to be evacuated , So any choices as conservative treatment is not enough.
Incomplete abortion Vaginal bleeding, lower abdominal cramps that radiate to back +
Dilated cervix + Evacuation of some fetal tissue - U/S shows: retained some products of conception . Complete abortion
Colicky suprapubic pain(uterine contractions) + dilated cervix & passage of whole fetal tissue along vagina with moderate bleeding( No retained products of conception) followed by ceasing of pain & closing of cervix.
P hysical examination shows: Closed cervix + blood pooled in vaginal vault. - U/S shows: empty uterus
Missed abortion :
Spontaneous abortion < 20 weeks GA & fetal weight < 500 gm.
Fetal demise + retained products of conception + closed cervix
Loss of pregnancy symptoms ( nausea & vomiting , breast tenderness )+ brown vaginal discharge.
The most appropriate next step in diagnosis of spontaneous abortion is transvaginal U/S to : 1) Document presence of uterine contents.
2) Visualize heart motion.
Most appropriate next step in management is removal of contents of conception with either: 1) Surgical: Dilatation & Curettage.
Medical : Misoprostol
Expectantly , with serial imaging to ensure complete expulsion of the contents.
Septic abortion :
Female came to emergency department with 2 days history of: fever + shaking chills + lower abdominal pain WITH a history of abortion 3 days ago.
Physical examination :
Lower abdominal tenderness
Enlarged , tender uterus with a dilated cervix = with purulent , offensive discharge coming from it.
Treatment:
The most appropriate sequence in management is :
Cervical & blood culture , antibiotics , gentle suction curettage (in sequence)
First obtain blood and cervical/endometrial cultures, then give IV broad spectrum antibiotics Immediate surgical evacuation by gentle suction curettage ( vigoruous curettage may cause uterine perforation) of the uterine contents is then required in order to remove the infectious nidus.
Physicians can refuse to perform elective abortions for personal or professional reasons. If you refuse to perform any procedure then you should: refer the patient to another physician who can and will.

Diethylstillbestrol (DES):
The most important risk factor for squamous cell carcinoma of cervix & vagina : HPV. |
3- hydatiform mole :
The increased in BP that appears before 20 weeks gestation is either : chronic HTN or hydatiform mole.
Gestational hypertension (formerly known as pregnancy-induced hypertension) is idiopathic hypertension without significant proteinuria (< 300 mg/L) that begins in the second half of pregnancy, during labor, or within 48 hours of delivery.
Some patients may go on to develop preeclampsia.
Retrospective diagnosis is made 1–12 weeks after delivery.
A ntepartum hemorrhage :
Maintenance of airway , breathing , circulation is always first priority in any patient came to ER with antepartum hemorrhage Most appropriate next step is: obtain venous access with 2 large bore cannulas (Hemodynamic resuscitation) in any patient hemodynamically unstable " Hypotension / tachycardia / cold exteremities
Placental abruption (antepartum hemorrhage) :
Premature placental separation initiated by hemorrhage in the decidua basalis.
High index of suspicion in patients presenting with Painful 3rd trimester bleeding "dark-red" (maternal in origin) , (bleeding can be concealed in 20% of cases) with normal U/S , with :
Uterine tenderness
Uterine hyperactivity
Uterine tone is increased
N.B: absence of blood of pelvic exam doesn't rule out this condition
U/S detects as few as 25% of all placental abruptions role of U/S in ante-partum hemorrhage is primarily to rule out placenta previa and NOT to diagnose placental abruption.
Treatment :
If patient is unstable (hypotensive, tachycardia) + continued bleeding + FHR is alarming :
Obstetrical indications OR Unfavorable cervix (early stage) Emergency (immediate NOW!) C.S .
If labor is at advancing stage Vaginal delivery with induction of labor (vaginal) may be tried.
If mother is stable , fetus is at term & doing well , labor has already started & progress Vaginal delivery with augmentaion of labor, if necessary.
Stable mother + away from term : Conservative treatment (rarely needed).
Uterine rupture
(Clinical presentation is highly variable and need high index of suspicion)
TTT: delivery by emergency C.S |
-- Intense abdominal pain + mild or massive vaginal bleeding -- after rupture occurs , slight relieve followed by return of pain may occur -- Vitally : patient usually present with signs of hypovolmic shock ! -- Presenting part may retract (Loss of fetus station!!) and no longer palpated on pelvix exam / where fetal limbs may easily palpated by abdominal examination. - It's : 1- mostly problem during active labor NOT during antepartum.

|
||||||||||||||||||||||||||||||||||||||
Vasa previa |
Rare condition in which the fetal blood vessels traverse the fetal membranes across the lower segment of the uterus between the baby and internal cervical os (velamentous cord insertion).
Presents with : - Painless anterpartum (3rd trimester) /intrapartum hemorrhage (after natural or artificial rupture of membranes "amniotomy" + associated with rapid deterioration of FHR from tachycardia to bradychardia to a sinusoidal pattern (maternal vital signs are normal) : immediately after rupture of membranes, the baseline FHR increases to 160 beats/min. and then drop to 70 beats/min. with repeatitve late deceleration. The most likely cause of the current condition is : ruptured fetal umbilical vessels.
