fetal station

Station refers to the relationship of the presenting part of the fetus to the ischial spines of the pelvis.
-Zero station(0): presenting part is at the level of the ischial spines
-Minus station(-): presenting part is above the ischial spines
-Plus station (+): presenting part is below the ischial spines

fetal position

The health care provider will determine fetal position by first establishing the presenting part (occiput, brow, etc.).The provider then determines if the part is facing the maternal right or left side and also which direction it is facing in relation to the maternal pelvis.

4 ps: passageway

-consists of bony pelvis, soft tissues of cervix and vagina(bony pelvis)

-pelvic shape: Gynecoid (most favorable for vaginal birth), Anthropoid, android and platypelloid

-pelvic dimensions: most import is obstetric conjugate; most desired shape to facilitate an easier delivery.

-soft tissues:Cervix must completely 100% effaced and dilated for the fetus to be born. Full dilation is equal to 10 cm; known as the second stage of delivery; Vagina

-cervical effacement and dilation: before labor, early effacement, complete effacement, full dilation

4 pelvic shapes and descriptions

-gynecoid pelvis, most favorable for vaginal birth. rounded shape allows fetus room to pass

-anthropoid pelvis, elongated in it dimensions. Can prevent vaginal delivery in some women

-android pelvis, heart shaped. Large babies become stuck and must be delivered c-section although smaller baby may be able to fit

-platypelloid pelvis, flat with a narrow anterior-posterior diameter and wide transverse diameter. Baby will be delievered c-section

- 3 main presentations: head(cephalic
presentation majority of fetuses, feet or
buttocks (breech presentation),
shoulder(shoulder presentation is
uncommon)
-fetal attitude together determine the presenting part, relationship of fetal parts to one another.( Flexion, military, brow, face )]
-Fetal position: presenting part and location to the reference point,
-first letter/designation: refers to side of
maternal pelvis toward which presenting
part is face , R or L.
-second letter/designation: reference point
on presenting part, Occiput, Frontum or
brow, Mentum or chin, Sacrum, Scapula
-Third letter/designation: specifies
direction presenting part is facing,
Anterior(A) front of pelvis, Posterior(P)
back of pelvis, Transverse(T) side of pelvis
-ROA or LOA most favorable fetal positions
for vaginal birth
-fetal station: relationship of presenting part to ischial spines

4 ps: primary powers

The primary power of labor comes from involuntary uterine contractions, serves to efface and dilate the cervix

Maternal pushing efforts supply secondary powers during the second stage of labor

contraction pattern: frequency, duration and intensity

resting interval

must be periods of relaxation between contraction: allow reoxygenation to fetus, momentary relief for woman

4 ps: secondary powers

Maternal psyche is an important influence on the labor process
Current pregnancy experience
Previous birth experiences
Expectations for current birth experience
Preparation for birth
Presence and support of birth companion
Woman’s culture influence

Nursing interventions can help break the cycle of fear, tension, and pain that can interfere with labor

table 8.2 true labors

Cervical changes: progressive dilation and effacement

Membranes: may bulge or rupture spontaneously

Bloody Show: present

Contraction Pattern: Regular (may be irregular at first) pattern develops in which contractions become increasingly intense and more frequent

Pain Characteristics:Often starts in the small of the back and radiates to the lower abdomen; may begin with a cramping sensation

Effects of walking:Contractions continue and become stronger

table 8.2 false labors

Cervical Changes:no change

Membranes:remain intact

Bloody Show:Absent; may have pinkish mucus or may expel mucus plug

Contraction Pattern: Pattern tends to be irregular, although the contractions may seem to have a regular pattern for a time

Pain Characteristics:May be described as a tightening sensation; usually the discomfort is confined to the abdomen

Effects of walking:May decrease the frequency or eliminate the contractions altogether

mucus plug

Sometimes the mucus plug is expelled a week or two before labor begins. When the mucus plug passes, the woman will notice a one-time clear or pink-tinged discharge that is the consistency of jelly.

table 170; patterned breathing techniques for labor; slow paced breathing

The woman takes slow, deliberate breaths while she focuses on maintaining a relaxed stance. She may use effleurage, music, or any technique that encourages relaxation while using slow-paced breathing. The rate is approximately 6–10 breaths per minute

table 170; patterned breathing techniques for labor; Modified-paced breathing

The woman begins taking slow, deep breaths at the beginning of the contraction. She then increases the rate while decreasing the depth of respirations as she reaches the contraction peak, after which she slows the rate and increases the depth

table 170; patterned breathing techniques for labor; patterned-paced breathing or the pant-blow technique

This technique is similar to modified-paced breathing with the addition of a rhythmic pattern. The woman takes four light breaths and then blows out through her lips, as if she is blowing out a candle. The woman repeats this pattern through the peak of the contraction

know when it is appropriate to receive pain medication and when it is not (patient education)

positions of comfort during labors pg 171,172

Any position of comfort is acceptable, as long as the fetal heart rate stays within the normal range. If the woman wants to be on her back, be certain to place a pillow or a wedge under one hip to prevent supine hypotension. The woman may find a birthing ball to be helpful. The ball allows her to rock and move to a position of comfort. Women who ambulate and reposition themselves as needed during labor tend to report higher satisfaction levels with the birthing process.

factors that influence labor pain pg 168

threshold, pain threshold is the level of pain necessary of for an individual to perceive pain pain tolerance refers to the ability of an individual to withstand pain once its recognized

nonpharmacological interventions to control pain to use during labor

Encourage the use of relaxation techniques. Reinforce the use of patterned breathing. Encourage the use of effleurage for as long as it is helpful. Encourage the use of counterpressure when effleurage is no longer helpful. The use of touch, such as effleurage and pressure, can interrupt the sensation of pain. Offer complementary therapies to increase comfort, such as a birthing ball or hydrotherapy, as appropriate. Allow alternative pain treatments that are culturally relevant to the client, if not contraindicated during labor. Nonpharmacologic interventions to relieve labor pain include continuous labor support, comfort measures, various relaxation techniques, intradermal water injections, and acupressure and acupuncture.

box 10-8 pg 196

box 10-9: food and fluid intake during labor

In the United States for the past several decades, the normal practice has been to withhold food and fluids from the laboring woman. The rationale for this practice was to prevent the woman from aspirating in the event that anesthesia was needed for a cesarean delivery. However, the woman needs fluids during labor to prevent dehydration and ketosis. Practices vary at hospitals across the country. The general consensus is for the woman to avoid solid food but allow clear liquids. Many health care providers prefer to give IV fluids to every woman in active labor and allow only ice chips, whereas others allow clear liquids. The nurse should follow the birth attendant’s recommendations and facility policy regarding food and fluid intake during labor
