INTRAPARTAL CARE ASSESSMENT Flashcards
e series of events by which uterine contractions and abdominal pressures expel the fetus and placenta from the woman’s body
LABOR
Uterine muscle stretching which results in prostaglandin release
Pressure on the cervix, which stimulates the release of oxytocin
Oxytocin stimulation which works together with prostaglandin
Change in the ratio of estrogen to progesterone
Placental age
Rising fetal cortisol level
Fetal membrane production of prostaglandin
Seasonal and time influences
Factors that influence labor onset
-Lightening
-Increase level of activity
-Braxton Hicks contraction
-Ripening of the cervix
Preliminary Signs of Labor
- Uterine contraction
- Show – blood and mucus
- Rupture of the Membranes
Signs of True Labor:
initiation of effective, productive, involuntary uterine contractions
Uterine contraction
- Increment/ Crescendo – intensity of contraction increases
- Acme/ Apex – contraction reaches its height or peak
- Decrement/Decrescendo – intensity of contraction decreases
Uterine contraction Phases
Duration
Intervals
Frequency
Intensity
Observation of Contraction
from the beginning of one contraction to the end of same contraction.
Duration
Duration during EARLY STAGE OF LABOR
20 to 30 seconds
Duration during LATE STAGE OF LABOR
60 to 70 seconds
from the end of one contraction to the beginning of the next
Intervals
Interval during EARLY STAGE OF LABOR
40-45 minutes
Interval during LATE STAGE OF LABOR
2-3 minutes
from the beginning of one contraction to the beginning of the next contraction
Frequency
– the strength of the contraction
– mild, moderate, strong
Intensity
- Intrauterine infection
- Prolapse of the umbilical cord
Two risks associate with Rupture of Membranes (ROM)
- Passage – uterus, cervix, vagina, external perineum
- Passenger - fetus
- Power – uterine factors
- Psyche
- Placenta
Components of Labor (5 Ps)
Are systemic method of observation and palpation to determine fetal presentation and position
Leopold’s Maneuver
Determine what fetal part is at uterine fundus
First Maneuver (Fundal Grip)
buttocks should feel irregular shape and firm
fetus is in the vertex position (head first)
head should feel hard, round and movable
fetus is in breech position
- Identifies and describes the fetal parts contained on each side of the uterus.
- Locates for the position of the fetal back and auscultate for the fetal heart beat
Second Maneuver (Umbilical Grip)
smooth, hard surface on one side
fetal back
Identifies the presenting part to determine the presentation and it’s mobility to determine engagement.
Third Maneuver (Pawlick’s Grip)
If the fetus is in the vertex and has descended
you’ll feel a less distinct mass
If the fetus is in the breech position
you’ll also feel a less distinct mass, which could be the feet or knees
- Determines the fetal attitude.
- Can determine flexion or extension of the fetal head and neck
Fourth Maneuver (Pelvic Grip)
- the position of the fetal presenting part and its descent into the pelvis — - how far has the fetus descended
- the ischial spines of the maternal pelvis are used to describe station 0.
Fetal station
described by the relationship of the long axis of the fetus to the long axis of the mother
Fetal Lie
the most common fetal lie
vertical lie
a problem with a term baby and labor approaching
Transverse lie
a problem in a term pregnancy
Oblique Lie
Denotes the body part that will first contact the cervix or deliver first
Fetal Presentation
- Cephalic
- Breech Presentation
- Shoulder (Transverse)
Types of Fetal Presentation
a) Vertex
b) Brow
c) Face
d) Mentum
Types of CEPHALIC PRESENTATION
parietal bone (full flexion)
VERTEX PRESENTATION (CEPHALIC)
head is moderately flexed (military)
BROW PRESENTATION (CEPHALIC)
extension of head, face
FACE PRESENTATION (CEPHALIC)
hyperextension of the head (chin)
MENTUM PRESENTATION (CEPHALIC)
head is the presenting part
CEPHALIC PRESENTATION
buttocks of the baby are presenting first at the bottom of the uterus
BREECH PRESENTATION
- Frank Breech
- Complete Breech
- Incomplete Breech
Types of BREECH PRESENTATION
legs are flexed at the hips and extended at the knees so the feet are up by the head.
Frank Breech
one or both of the legs are flexed.
Complete breech
one or both hips are not flexed and the feet and knees are
often below the buttocks
Incomplete Breech
– fetus is lying horizontally in the pelvis.
- Presenting part can be the shoulder, iliac crest, hand, or elbow
SHOULDER (TRANSVERSE) PRESENTATION
Relaxed abdominal walls from grand multiparity
Pelvic contraction in which horizontal space is greater than the vertical space
Placenta previa (placenta located low in the uterus)
CAUSES OF SHOULDER (TRANSVERSE) PRESENTATION
the relationship of the presenting part to a specific quadrant of the woman’s pelvis
Fetal Position
- Right Anterior
- Left Anterior
- Right Posterior
- Left Posterior
FOUR QUADRANTS
- Occiput
- Breech – Sacrum
- Face – Chin (Mentum)
- Shoulder – Scapula or acromion process
FOUR LANDMARKS
whether the landmark is pointing to the mother’s right or left
FIRST LETTER
denotes the fetal landmark:
O- occiput
Sa – sacrum,
M – mentum
A- acronium
MIDDLE LETTER
whether the landmark points anteriorly (A), posteriorly (P), transverse (T) (w/ regards to mother’s ante and poste)
LAST LETTER
Combined abdominal inspection and palpation
Vaginal Examination
Auscultation of FHT
Sonography
FOUR METHODS USED TO DETERMINE FETAL POSITION, PRESENTATION, AND LIE
