OB test 13 Flashcards
Hypertonic uterine dysfunction
contractions Q 1-1/2 minutes, duration 90 sec, baseline 10mmhg.
Dilation and effacement does not progress.
Hypotonic uterine dysfunction
contractions Q 7 minutes, 50 sec duration, intensity increases 25mmhg.
Initially good labor, uterus tires at 4 cm dilation.
Precipitous labor
rapid, less than 3 hours.
Problem- trauma to mom or baby.
prolonged labor
exceeds normal time >20 hrs.
Arrested labor
progress stops, fetal descent stops.
Cause- CPD, fetal malproportion
CPD
cepelopelvic disportion- baby head cannot fit
Shoulder dystocia
baby descends and should gets stuck behind symphysis pubis.
Tx- suprapubic pressure, mcroberts manuter (keens to chest), woodys screw manuver- turn baby.
Velamentous intersion
cord divides before connecting to the placenta.
Risk- hemorrhage, increase risk compression.
Abnormal cord length
long- inc nuchal cord/knots
short- conpression, abrupt placenta
Prolapsed cord
ROM before presenting part is snug in pelvis.
Risk- cord rushes out with water
tx- get presenting part off cord, rish C/S
Succenturiate placenta
accessory lobe. Continues to bleed after delivered placenta (fundus will be firm)
Risk- can detach=hemorrhage
Circumvallate placenta
double fold of anmion and chorion. Sec surface are for blood vessels to perfuse.
risk fetal dealth, SGA, premature
Battledorf placenta
cord insterts at margin= poor circulation
Placental infarcts/calcification
Ca deposits= old placenta
Placenta previa
implants lower uterine segment. WILL LEAK BLOOD.
Mom anemic, hemorrage during preg.
DR MUST CHECK, not a RN
Abruptio placenta
premature separation of normally implanted placenta after 20 wks
S&S- pain btw contraction, late decals.
Amniotic fluid embolism
amniotic fluid enter materal blood. S&S- resp distress, brain, dyspnea, hypotension
Sedative (ambien, phenergan, benadryl)
used during false/early labor. FETUS greatly effected.
Admin at peak of contraction- fetus will be less effected
Pudendal- regional anesthesia
nerve, either side of perineum. relief perineal stretching. No used often.
General anasthesia
Emergeny C/S, crosses placenta. prepare for fetal resussitation.
Spinal anasthesia
subarachnoid space, mom can’t move legs.
SE- spinal HA
