Intrapatum Terms Flashcards
opening or enlargement of the external cervical os
dilation
cervix effaces (thins) to allow the presenting fetal part to descend into the vagina
effacement
relationship of the presenting part to the level of the maternal pelvic ishial spines
station
detects the fetal pulse by sensing and analyzing tissue movements via doppler ultrasound
electronic fetal monitoring
transitory abrupt increases in the FHR above the baseline that less than 30 seconds from onset to peak
acceleration (FHR- fetal heart rate)
transient fall in FHR caused by stimulation of the parasympathetic nervous system
deceleration (FHR)
fluctuations in baseline FHR
variability (FHR)
FHR between 110-160
baseline (FHR)
laboring woman with a slower than normal rate of cervical dilation, slow progress
cephalopelvic disproportion (CPD)
method for determining the presentation, position, and lie of the fetus
1: fetal part is located at fundus
2: which maternal side is fetal back located
3: presenting part
4: fetal head flexed and engaged in the pelvis
Leopold maneuvers
temporary, recurrent changes made in response to a stimulus such as a contraction
periodic changes (FHR)
occurs when the fetal presenting part begins to descend into the true pelvis
lightening
how often contractions occur and is measured from beginning of contraction to the beginning of the next contraction
frequency (contractions)
how long a contraction lasts and is measured from beginning and end of the same contraction
duration (contractions)
APGAR
pelvis first
breech
surgical birth of fetus through an incision in the abdomen and uterine wall
cesarean
trial of labor after cesarean or vaginal birth after at least 1 cesarean
TOLAC or VBAC
green fluid, baby pooped
meconium
woman servant or caregiver, offers emotional and practical support to a mother or couple before, during, and after childbirth
doula
process by which the cervix softens via the breakdown of collagen leading to its elasticity and distensibility preceding cervical dilation
cervical ripening
signifies the entrance of the largest diameter of the fetal presenting part into the smallest diameter of the maternal pelvis
engagement
where intensity of the contraction is determined
IUPC (intrauterine pressure catheter)
placement of a spiral electrode into the fetal presenting part to assess FHR and pressure transducer placed internally within the uterus to record uterine contractions
FSE (fetal scalp electrode)
synthetic oxytocin to induce or augment labor by stimulating uterine contractions
pitocin
change shape of the fetal skull at birth as a result of overlapping of the cranial bones
molding
part that is presented in labor
presenting part
seeing or palpating the cord outside or within the vagina in addition to abnormal FHR patterns
prolapsed cord
blood collecting beneath the scalp
cephalohematoma
fluid collecting in the scalp, edema of the scalp at the presenting part
caput succedaneum
