OBGYN Nagy Questions Flashcards
Definition of Preeclampsia and Eclampsia
After 20th week of gestation
Preeclampsia - BP > 140/90
proteinuria >300mg/24hr
Eclampsia - tonic-clonic seizures
Gestational Diabetes
Done in all pregnancies - screen between 24-28 weeks
Healthy = Fasting glucose < 5.6 mmol/L
FG 5.6 - 7.0 mmol/L - Do OGTT
FG > 7.0 mmol/L on 2 separate occasions - GDM
Oral Glucose Tolerance Test
OGTT - consume 25g of glucose after fasting
minute 0 <7.0 mmol/L
If <7.8 - 11.1 mmol/L - Impaired Glucose Tolerance (IGT)
If > 11.1 mmol/L - DM
Indications of C- section
Maternal-Fetus perspective
- cephalopelvic disproportion
- failed induction of labor
Maternal Perspective
- eclampsia
- cerival cancer
- fibroids, tumor
- herpes
Fetal
- “non-reassuring” fetal HR - bradycardia
- cord prolapse
- Malpresentation
- Multiple gestations
Fetal abnormalities
- hydrocephalus
Placenta
- previa
- abruptio
When is US in pregnancy done
week 6-7 - confirm pregnancy
- gestational sac, HR
Location: intra/extrauterine
week 11-13
- congenital malformations
- nuchal translucency (Down’s)
- Neural Tube defects
- Biometrics
week 18-20
- congenital malformations
week 30-31
- IUGR
- late congenital malformations
week 36-38
- fetal presentation
- fetal weight
- information for prep of delivery
Approach to Placental abruptio
and Placental previa
use hands to palpate the uterus
abruptio - painful, hard uterus –> C-section
previa - painless, CTG is normal
Post-partum hemorrahge
tissue - retain placenta
trauma - vaginal lacerations
thrombin - coagulopathy (DIC)
Tone - uterine atony (need to exclude other causes)
Stages of Birth
- onset of labor - longest stage
- latent (3cm)
- active (3-10 cm) - baby: 30-90 mins
- propulsive phase - full dilation, descend to pelvic floor
- expulsion phase - ends with delivery of baby - placenta: 5-30 mins, separation
- expulsion of placenta
- expulsion of membranes - Recovery: 2 hours, after expulsion of placenta
- inc. risk of bleeding
- repair lacerations
- RhoGAM - a medicine that stops your blood from making antibodies that attack Rh-positive blood cells
Techniques of C-section
Abdominal Wall
- transverse, pfannenstiel
- vertical, midline
Uterus
- lower segment incision - transverse
- classical - vertical
Pearl Index
number of pregnancies in 100 females/year with chosen contraceptive
- OCP: 0.1-2.5
- Plan B: 0.5 - 2.5
- IUD 0.5-5
- Condom 3-28
- Sterilization 0.3-6
Routine Examiations
colposcopy
cytology
bimanual exam
breast exam
Long term OCP use
GOOD:
- dec ovarian/endometrial cancer
- dec bone loss
- dec dysmenorrhea
- dec acne
- dec risk of trisomies with inc in maternal age
- regulates cycle
BAD:
- inc DVT/stroke
- inc BP
- inc weight
Endometriosis
endometrial like tissue outside the uterine cavity
DX - Gold standard - Laparscopic visualization
TX - surgery
- pseudopregnancy
- pseudomenopause - GnRH analogue
Urinary incontinence
irritative:
- urinalysis – cystitis/tumor/foreign body
stress:
- loss of bladder support – cough – urge
- hypertonic – inc detrusor
TX - anticholinergics
overflow/neurogenic:
- hypotonic w/ dribbles
TX - cholinergics
bypass/fistula
Main Vaginal infections
bacterial vaginosis
trichomonas
mycosis (Candida)
Condyloma
Spontaneous abortion
pain and bleeding
DX: cervix, US, hCG
Contraindications to Tocolysis
Obstetric:
- severe abruption
- ruptured membranes
- chorioamnionitis
Fetal:
- lethal anomaly
- fetus has died
- fetal jeopardy
Maternal
- eclampsia
- advanced dilation
Leopold maneuvers
- Fundal grip
- Umbilical grip
- Pelvic Grip (first)
- Pawlick grip (2nd pelvic grip)
Leopold maneuver - 1. Fundal grip
- Fundal grip - palpate upper abdomen with both hands
Leopold maneuver - 2. Umbilical grip
- Umbilical grip - palpate to localize fetal back. One palm fixed, while the other explores one side then change
Leopold Maneuver - 3. Pelvic Grip (first pelvic grip)
- Pelvic Grip (first) - determine what fetal part is lying above the inlet. grasp the lower portion of the abdomen just above the pubic symphysis with thumb and fingers of the right hand
Leopold Maneuver - 4. Pawlick grip (2nd pelvic grip)
- Pawlick grip (2nd pelvic grip) - face woman’s feet, attempt to locate fetus’ brow. Fingers of both hands move gently down the sides of the uterus to pubis. The side where there is resistance to the descent of the fingers is greatest where the brow is located.
How to stop uterine bleeding
Old - D&C
Young - progesterone – preserve fertility
What is Mayer-Rokitansky-Kuster-Hauser Syndrome
i.e. Mullerian agenesis
congenital malformation where the mullerian duct fails to develop
has missing uterus, cervix, vagina
there is a variable degree of upper vaginal hypoplasia (shortened)
causes 15% of primary amenorrhea
ovarias are still intact so ovulation occurs - will enter puberty and have secondary sex characteristics
