INTRAPARTUM Flashcards
the series of events by which uterine contractions and abdominal pressure
expel a fetus and placenta from the uterus
Labor
Labor normally begins between _____ of pregnancy
37 and 42 weeks
softening of the cervix
ripening
In full flexion what is presented to the birth canal
suboccipitobregmatic
If the head is held in moderate flexion what is presented in the birth canal
occipitofrontal diameter
In poor flexion (the head is hyperextended) what is presented
occipitomental
overlapping of skull bones along the suture lines
Molding
describes the degree of flexion a fetus assumes during labor or the relation of the fetal parts to each other
Attitude
4 cephalic attitudes
Vertex
Sinciput
Brow
Face
usual “fetal position” advantageous for birth
vertex
less than the usual
amount of amniotic fluid present is termed
oligohydramnios
is the relationship between the long (cephalocaudal) axis of the fetal body and the
long (cephalocaudal) axis of a woman’s body
Lie
denotes the body part that will first contact the cervix
Fetal Presentation
4 cephalic presentations
Vertex
Brow
Face
Mentum
edema on fetal head from the continued pressure
caput succedaneum
the relationship of the presenting part to a specific quadrant and side of
a woman’s pelvis
Fetal position
the most
common fetal position
LOA
a fetus is born fastest from an ____ position
ROA or LOA
Labor can be considerably extended if the position is
posterior (ROP or LOP)
refers to the settling of the presenting part of a fetus far enough into the
pelvis that it rests at the level of the ischial spines
Engagement
A presenting part that is not engaged is said to be
floating
- One that is descending but has not yet reached the ischial spines
dipping
refers to the relationship of the presenting part of the fetus to the level of the
ischial spines
Station
shortening and thinning of the cervical canal
Effacement
The Stages of Labor
begins with the initiation of true labor contractions and ends when the cervix is fully dilated
from the time of full dilatation until the infant is
born
placental stage, lasting from the time the infant is born until after the
delivery of the placenta
placental stage, lasting from the time the infant is born until after the
delivery of the placenta
an algorithm for determining normal labor progress, has been utilized in labor settings
everywhere
Freidman’s curve
first stage of labor takes how many hours to complete
12 hours
1st stage of labor is divided into 3 segments:
latent, an active, and a transition phase.
phase begins at the onset of regularly perceived uterine contractions
and ends when rapid cervical dilatation begins
Latent Phase
e phase of labor, cervical dilatation occurs more rapidly
Active Phase
contractions reach their peak of intensity, occurring every 2 to 3 minutes with a duration of 60 to 70 seconds, and a maximum cervical dilatation
The Transition Phase
