6 PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
Lightening
Weight Loss
Increase Energy/ Activity Level
Braxton Hicks
Ripening of the Cervix
Rupture of Membranes
PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
Settling or descent of the fetal head into the
pelvic inlet, experience of “dropping” of the
baby (it happens 2 weeks before EDC)
Lightening
PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
why do they loss 1-3 pounds; 1-2 days; prior to labor onset
because of the decrease of
progesterone, may decrease in fluid
retention
PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
1-2 days prior to labor onset
why there is an increase in energy and activity level
; because of the increase of adrenaline
for the work ahead
PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
- irregular painless “practice” contractions
- -during at night
- usually confine at abdomen only
Braxton-Hicks
PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
from Goodell sign to butter soft
Ripening of Cervix
PRODROMAL/PRELIMINARY SIGNS PRIOR TO TRUE LABOR
labor is inevitable (labor should occur within next the 24 hours and delivery should occur within 24 hours to avoid infection)
* sa ER, ask the client to lie down, check the fetal heart rate, tell the patient to avoid, to ambulate
Rupture of Membranes
4 SIGNS OF TRUE LABOR
- Uterine contractions
- Cervical Dilation and Effacement
- Pain in the back that radiates around to the abdomen
- Bloody Show/Show
SIGNS OF TRUE LABOR
- surest signs of labor onset
- it occurring during regular intervals and
increases in duration and intensity, the
intensity usually occurs in walking
Uterine Contractions
SIGNS OF TRUE LABOR
enlargement of external cervical
os up to 10 cm as a result of uterine
contractions and because of pressure of both presenting part and bag of water
Dilation
SIGNS OF TRUE LABOR
- shortening and thinning of the
cervical canal from 1 to 2 cm to one in which
no canal as Distinct from the uterus exist - express in percentage
- in a primipara, the cervix will first efface then, dilate; in a multipara, effacement and
dilation occur simultaneously.
Effacement
SIGNS OF TRUE LABOR
expulsion of mucus plug, labor begins 2 to 3
days after bloody show or bloody show may be observed at the onset of labor
* pressure of the descending part of the fetus causes rupture of capillaries in the mucus
membrane of cervix
- blood mixes with operculum in released
result: pinkish vaginal discharge
*if bright red, it means active ang
bleeding
Bloody Show/Show
Phases of Uterine Contractions
s the first
phase during which the intensity of
contraction Increases
Increment (Crescendo)
Phases of Uterine Contractions
the hike of the uterine
contractions
Acme (Apex)
Phases of Uterine Contractions
the last phase during which intensity contraction decrease
Decrement (Decrescendo)
2 Distinct Portions of Uterus
becomes thick and active in order to expel the fetus
- The only part that contracts
Upper Uterine Segment
2 Distinct Portions of Uterus
becomes a thin wall, supple and passive, that the fetus pushes out easily
Lower Uterine Segment
formed at the boundary of the upper and lower uterine segment
Physiological Retraction Ring
when the Fetus is larger than the birth canal the round ligament of the uterus becomes tense during expulsion, this tense will result
in the formation of abdominal indentation
Danger sign of labor
Pathological Retraction Ring (Bandal’s
Ring)
MECHANISM OF LABOR
the Fetus has reached the pelvic inlet
Engagement
MECHANISM OF LABOR
From AP to transverse, then AP to AP, fetal head rotates to
accommodate itself to changing diameter of the pelvis
Internal Rotation
MECHANISM OF LABOR
as descent occurs, pressure from
the pelvic floor causes the fetal chin to bend towards the chest
Flexion
MECHANISM OF LABOR
fetus goes down the birth canal
Descent
MECHANISM OF LABOR
as head comes out, the back of
the neck beneath the pubic arch l, the head
extends and the forehead, nose, mouth the chin
appear
Extension
