Alpha-fetoprotein: causes for increased maternal serum AFP during pregnancy

"Increased Maternal Serum Alpha Feto Protein":

Intestinal obstruction
Multiple gestation/ Miscalculation of gestational age/ Myeloschisis
Spina bifida cystica
Anencephaly/ Abdominal wall defect
Fetal death
Placental abruption

Alpha-fetoprotein: some major causes for increased maternal serum AFP during pregnancy

TOLD:

Testicular tumours
Obituary (fetal death)
Liver: hepatomas
Defects (neural tube defects)
Dysfunctional uterine bleeding (DUB): 3 major causes

DUB:

Don't ovulate (anovulation: 90% of cases)
Unusual corpus leuteum activity (prolonged or insufficient)
Birth control pills (since increases progesterone-estrogen ratio)

IUGR: causes

IUGR:
Inherited: chromosomal and genetic disorders
Uterus: placental insufficency
General: maternal malnutrition, smoking
Rubella and other congenital infecton
Early cord clamping: indications
RAPID CS:
Rh incompatibility
Asphyxia
Premature delivery
Infections
Diabetic mother
CS (caesarian section) previously, so the funda is RAPID CS
IUD: side effects

Period that is late
Abdominal cramps
Increase in body temperature
Noticeable vaginal discharge
Spotting



Oral contraceptives: side effects

CONTRACEPTIVES:

Cholestatic jaundice
Oedema (corneal)

Thromboembolism
Intracranial hypertension
Vomiting (progesterone only)
Erythema nodosum/ Extrapyramidal effects
Sensitivity to light
FORCEPS/VACUUM DELIVERY

A - Anaesthesia/Assistance( anaesthetist, colleague,paediatrician) Think and prepare for shoulder dystocia
B- Bladder empty
C- Cervix fully dilated
D- determine position
E- Explain to the patient/ exit plan if it fails, ready for cesarean section
F - Fontanelle ( to check position )
G - Gentle traction
H- Handle elevated for forceps
Halt for vacuum ( no descent with 3 pulls, 3 times pop off )
I - Incision/Episiotomy
J- remove forceps when jaw visible

Forceps: indications for delivery

FORCEPS:

Foetus alive
Os dilated
Ruptured membrane
Cervix taken up
Engagement of head
Presentation suitable
Sagittal suture in AP diameter of inlet


Delivery: instrumental delivery prerequisites

AABBCCDDEE:

Analgesia
Antisepsis
Bowel empty
Bladder empty
Cephalic presentation
Consent
Dilated cervix
Disproportion (no CPD)
Engaged
Episiotomy


Indications of cesearian section

MICE CAME
M- Malpresentation
I- Induction failure
C- Cephalopelvic disproportion,contracted pelvis
E - Eclampsia
C- Cervical cancer
A- antepartum hemorrhge(Abruptio, placenta previa)
M- medical illness complicating pregnancy
E- Elderly primi
APGAR score components

SHIRT:
Skin color: blue or pink
Heart rate: below 100 or over 100
Irritability (response to stimulation): none, grimace or cry
Respirations: irregular or good
Tone (muscle): some flexion or active

Postpartum collapse: causes

HEPARINS:
Hemorrhage
Eclampsia
Pulmonary embolism
Amniotic fluid embolism
Regional anaethetic complications
Infarction (MI)
Neurogenic shock
Septic shock



Multiple pregnancy complications

HI, PAPA:
Hydramnios (Poly)
IUGR
Preterm labour
Antepartum haemorrhage
Pre-eclampsia
Abortion


Omental caking: likeliest cause

Omental CAking = Ovarian CA
---"Omental caking" is term for ascities, plus a fixed upper abdominal and pelvic mass. Almost always signifies ovarian cancer.


Polycystic Ovarian Syndrome (PCOS): first line treatment
Treat PCOS with OCP's (oral contraceptive pills).


DYSTOCIA

CAUSES:Remeber 4 Ps.
Passenger (large baby)
Passage (Abnormal Pelvis)
Propulsion (uterine contraction)
Proprotion (disproportion Cephalo-pelvic)


Labour: factors which determine rate and outcome of labour

3 P's:
Power: stength of uterine contractions
Passage: size of the pelvic inlet and outlet
Passenger: the fetus--is it big, small, have anomalies, alive or dead



Labour: preterm labor causes

DISEASE:
Dehydration
Infection
Sex
Exercise (strenuous)
Activities
Stress
Environmental factor (job, etc)

Antepartum hemorrhage (APH): major differential

APH:
Abruptio placentae
Placenta previa
Hemorrhage from the GU tract


Miscarriage: recurrent miscarriage causes

RIBCAGE:
Radiation
Immune reaction
Bugs (infection)
Cervical incompetence
Anatomical anomaly (uterine septum etc.)
Genetic (aneuploidy, balanced translocation etc.)
Endocrine


Shoulder dystocia: management

HELPER:
Call for Help
Episiotomy
Legs up [McRoberts position]
Pressure subrapubically [not on fundus]
Enter vagina for shoulder rotation
Reach for posterior shoulder and deliver posterior shoulder/ Return head into vagina [Zavanelli maneuver] for C-section/ Rupture clavicle or pubic symphisis


Cardiotocogram (CTG) interpretation

Dr. C. BraVADO
Define Risk
Contractions (in 10 mins)
Baseline Rate (should be 110-160)
Variability (should be greater than 5)
Accelerations
Decelerations
Overall (normal or not)



Diagonistic tests

CAT
C=CHORIONI VILOOUS SAMPLING=10-12wks. OF GEST. DONE
