OB Flashcards
what is preeclampsia
-HTN
-protein in urine
-edema
what is HELLP
-hemolysis
-elevated liver enzymes
-low platelets
what preterm tocolytics should you use
-Mag sulfate
-terbutaline
what are tocolytics
medications used to slow/stop the contractions of a woman’s uterus during pregnancy
what are the 3 types of breech delivery
-frank- butt present
-complete- both feet present
-footling- 1 foot is present
what is post partum hemorrhage defined as
greater than 500 cc blood loss after delivery
How do we control post delivery hemorrhage
-fundal massage
-oxytocin or ergometrine
-bimanual compression
-may need to give blood ( 1PRBC to 1 FPC)
how do you determine Mag toxicity in a pregnant woman
loss of deep tendon reflexes
who do we treat first when mom and baby are having health issues.
-treat mom 1st
-what’s good for mom is good for the baby
who consumes for O2; adults or infants
infants consume 2x the amount of O2 as adults
when do the fontanels close on a baby
-Anterior close at 12-18 months
-posterior close at/by 2 months
what is the treatment of Mag toxicity
calcium chloride (CaCl) 1g/10ml IVSP
sinusoidal rhythm instead of accelerations on fetal heart monitor
usually indicates anemia and fetal distress.
Late decelerations on fetal heart monitor
do not begin until peak of contractions.
Most worrisome
fetal hypoxia
Early decelerations on fetal heart monitor
seen when the baby’s head is compressed. often happens during late stages of labor
not harmful
Accelerations on fetal heart monitor
Important sign of well being during labor
What is variability on the fetal heart monitor
When the heart rate bounces around on the fetal heart rate monitor.
predictor of fetal well being
what is station
fetal head in relation to the mothers pubic bone.
expressed as a - or + as measured in cm
if still in the pelvic girdle it is a -
if it is outside the pelvic girdle it is a +
Stages of Labor
1st- cervical dilation and effacement
2nd- starts with crowning and ends with birth of baby
3rd- delivery of placenta
How to determine bradycardia in a fetus
HR below 120 bpm for 5-10 consecutive minutes
How to determine tachycardia in a fetus
HR above 160 bpm for 10 consecutive minutes
Normal HR for a new born
120-160 bpm
Dilation
refers to the size of the cervix opening
0-10
effacement
refers to the thickness of the cervix and is expressed in %
normal thickness is 2 cm
