Woman's Health Flashcards
What is a Bishop score? What is it used for?
Scoring of the cervix during/before labor. This helps us determine whether or not the patient is in labor, what phase of labor they’re in and how the labor is progressing. Predictor of whether or not IOL is necessary
Bishop score >8?
Vag delivery likely, the cervix will probably do just fine.
Bishop <6?
Probably need some kind of induction method
5 Components of a Bishop Score
“Call PEDS Fast”
Cervical Position (it kind of retracts for labor Effacement (thinning) Dilation Softness (consistency) Fetal Station
Stage I of labor
Onset of labor until complete dilation of cervix. Consists of active phase and latent phase
How long does stage 1 take if nullip? Mulltip?
Null: 10-12 hrs
Mull: 6-8 hrs
What defines the latent phase of labor?
Onset of labor until the cervix is dilated 3-4 cm. Not considered active until 3-4 cm.
When does active phase start? When does it end? How long does this take (null vs mull)
Starts at 3-4cm, ends at 9cm.
Null: 1cm/hr
Mull 1.2cm/hr
What are the 3 P’s
Power of contractions
Passenger- size and position of the kid
Pelvis/Passage- size/shape of pelvis
What defines stage 2 labor? Length of time null vs mull
9cm until the delivery of the infant
Null- >2 hours is considered prolonged. >3 if epidural
Mull- >1 hr is prolonged. >2 if epidural
Repetitive early & variable decels in stage 2 labor?
Totally normal! Have to do with contractions. Being repetitive is good
Late decels, bradycardia or loss of variability?
NOT OKAY! This is when we consider an urgent cesarean
What defines stage III delivery
Delivery of the infant until the delivery of the placenta. Takes 5-30 min
3 signs of placental separation
Cord lengthening
Sudden blood gush
Uterine fundal rebound as placenta detaches
First degree tear
Vaginal mucosa
Second degree tear
Perineal tear. Taint
3rd degree tear
Anal sphincter involvement
4th degree tear
Tears into the rectum
RF for molar pregnancy
Extremes in age. Hx of GTD. Nullip. OCP use
Pathognomonic for molar pregnancy
PEC, hyperemesis and hyperthyroidism happening <20 weeks. It’s like pregnancy gone rogue. ALSO HEAVY VAGINAL BLEEDING
PE on molar preg
PEC, hyperthyroid, NO FETAL HEART TONES, uterus is MASSIVE for GA, grape like goop coming out of the cervix, theca lutein cysts
Molar pregnancy on US
Molar tissue looks like “diffuse mixed echogenc pattern”. Not a fetus, it’s a weird clump of tissue made from chorionic villi and intrauterine blood clots.
Management of a molar pregnancy
Immediate removal to prevent persistant/malignant GTD.
Also tx the symptoms
PEC? Anti HTN
HCG induced hyperthyroid? BB to prevent thyroid storm
Done with childbearing? Cut that uterus out
Which type of mole is more likely to lead to persistent GTD
Complete
Why do we recommend patients to not have another pregnancy for 6-12 months after a mole pregnancy
We do serial HCG levels for months afterwards to watch the levels drop and make sure there’s no persistent disease going on. If the patient is pregnant so soon afterwards there’s A) a chance the mole could happen again and B) HCG levels will be high from that so we won’t know if there’s also something scary going on
What freaky kind of malignant GTD can happen from a complete mole
Choriocarcionma
Gestational HTN definition
HTN w/o proteinuria that happens after 20 wks. Previously normal BP too.
Lil bitch HTN, >140/90
PEC definition
HTN + Proteinuria after 20 weeks.
Proteinuria definition for PEC
> 0.3g in a 24hr urine. Remember there should be no proteins
Severe PEC definition
> 160/110, and protein >5g in a 24 hr or >3g in a spot, symptomatic HTN. This is pre HELLP and it’s very bad
Superimposed PEC
Newonset proteinuria or worsening BP in a woman with prexisting CHTN.
Or if they get HTN symptoms, like HA/scotoma/epigastric pain
Eclampsia definition
PEC + Seizures
Management for PEC
Delivery! IOL is GS for term moms, unstable moms or any pregnancy that shows lung development
Management for PEC with a stable preterm
Bedrest & betamethasone until we can induce
IOL with PEC, let’s talk mag
Give Mg (4g loading, 3g/hr maintenance) during labor, & 12-24 hrs PP
Signs of severe PEC
BP >160/110 >5g 24hr or >3g in a spot Oliguria Scotoma Pulm edema/cyanosis Epigastric/RUQ pain LFT fuckups Thrombocytopenia Fetal growth restriction
This is HELLP waiting to happen
Momma with signs of renal/liver failure/pulmedema/HELLP/DIC?
C SECTION TIME
Eclampsia managment
Seizure management, BP control, seizure ppx.
They get Mg from the time of diagnosis until 12-24hr pp. This is when it’s okay to load the fetus with Mg
Can we section a seizing mom because baby is having decels?
No fucking way. Decels are to be expected. Fix the seizures, fix the decels
What does HELLP stand for
Hemolytic anemia
Elevated Liver enzymes
Low Platelets
Signs of hemolytic anemia
Elevated LDH
Elevated Bili
Schistocytes on smear
Signs of elevated liver enzymes
Elevated AST/ALT
Signs of low platelets
thrombocytopenia
What week is the fundus at the umbilicus
24 weeks
Nageles rule
Subtract 3 months from the LMP and add 7 days
Don’t know the LMP but you want to calculate the EDD?
Via US, measure the crown-rump length. If done in the first trimester, this will give you a fairly accurate estimate. Within 3-5 days.
