Assessment & Care of the Laboring Woman
Lisa Van Gerpen, CNM, MSN
Initial Rapid Assessment
Presenting complaint (what brings you here)?
Gestational age?Any leaking, bleeding, or unusual discharge?
Time, color, amt?Any problems during your pregnancy?How many babies have you had?Assess labor progress if appears to be in
active labor.
Maternal Admission Assessment Medical History - chronic diseases(ie.
asthma,HTN), surgeries, allergies Obstetrical History (GTPAL) - type of delivery, complications
Gravida (G) - # of times a woman has been pregnant, regardless of the pregnancy outcome T - # pregnancies resulting in term delivery P - # pregnancies resulting in preterm delivery A - # pregnancies resulting in miscarriage or elective termination L - # living children
Parity
Para/Parity: # of pregnancies that reached 20 wks (# pregnancies, NOT # fetuses)
Example: G1 delivers triplets at 32 weeks. Still G1 P1. More helpful if recorded using
GTPAL method: G1 P0103 (0 term pregnancies, 1 preterm pregnancy, 0 aborted pregnancies, 3 living)
What’s their GTPAL?
1. Woman expecting 2nd baby. First baby born at 38.4 weeks, 2 ½ years old,
living.2. Woman expecting 3rd baby. 1st baby
born at 32 wks/living, 2nd baby born at 37.4 wks/died of SIDS.
3. 3rd pregnancy. 1st pregnancy term, 2nd pregnancy 35.6 wks, twins – all living.
Definition of “term”
Term is a pregnancy between 37-42 weeks.Further clarifications recommended byACOG and AWHONN:
Early term: 37 0/7 weeks through 38 6/7 weeks Full term: 39 0/7 weeks through 40 6/7 weeks Late term: 41 0/7 weeks through 41 6/7 weeks Postterm: 42 0/7 weeks and beyond
Maternal Admission Assessment
Current Pregnancy – review/obtain prenatal
record and birth plan
At a minimum, prenatal records should be sent to delivering facility at 36 weeks. This practice still leaves a gap for any visits occurring after this time.
Important to review: GBS status, problems such as substance abuse, gestational diabetes, gestational hypertension, etc.
Maternal Admission Assessment Vital signs (compare to PNR) Systems assessment (apical pulse, lung sounds, extremities- reflexes, clonus, Homan’s, edema, varicosities) Vaginal exam as appropriate – cervical assessment (dilatation, effacement, station), fetal position (lie, presentation, attitude, position), discharge and leaking
Fetal Admission Assessment Gestational age – LNMP,U/S Leopold’s maneuver (fetal position
and presentation) Fetal heart tones Fetal activity Fetal testing/treatments (US’s,NST’s,
genetic screening,etc)-results and reason for testing
Leopold’s Maneuver
Palpate fetal back/position Estimate fetal weight Palpate fetal movement Palpate uterine tone/tenderness
Leopold’s Maneuvers
Fundal Height
Fundal Heights
Fetal Lie
Long axis of fetus relative to mother Vertex (head) Breech Transverse Determine by Leopold’s and vaginal
exam If unable to tell for sure HAVE SOMEONE DOUBLE CHECK!!!
Fetal Lie
Fetal Presentation
Part of fetus entering pelvic inlet first
Fetal Attitude
Relationship of fetal head, shoulder, and legs to one another (flexion or extension) Flexion (normal vertex presentation) Extension (face presentation) Military (brow presentation)
Fetal Position
Note position of fetal denominator occiput sacrum mentum scapula
To maternal pelvis front (anterior) back (posterior) side (transverse)
Fetal Landmarks/denominators
Vertex(Occiput)
Face(Mentum)
Fetal Landmarks/denominators
Breech Shoulder (Sacrum) (Scapula)
Fetal Skull Landmarks
Determining Fetal Position
Molding of Fetal Head
Cervical Assessment
Expose perineum: look for amount of bloody show, wet/glistening perineum, malodorous discharge, ulcerations If blisters or raised vesicles noted, stop
exam and notify provider (may be herpes lesions)
Cervical Assessment
Hold hand sideways and insert fingers gently into vagina
Apply gentle downward pressure as you insert fingers to avoid pressure on anterior vaginal wall or urethra
Move fingers full length of vagina (do not allow 4th & 5th fingers to touch rectal area
Cervical Assessment
Assess dilatationAssess effacementAssess stationAssess if bulging membranes noted
Fetal StationDetermine relationship of the biparietal
diameter of the fetal head to the ischial spines(estimated in cm above or below)
Press in at sidewall of vagina at 3 & 9 o’clock 0 is at ischial spinesBallotable – head is above ischial spines and not
engagedUsually –1 to +1 during labor; if not, can be a warning sign that baby needs to change position to be able to drop into pelvis
Fetal Station
-3 to +3 -5 to +5
Tests to Confirm ROM
Pooling – visualize fluid w/speculum examNitrazine – pH paperFerning – microscopic examAmnisure- important to obtain prior to SVE if
possible rupture. False positives can occur if significant bleeding. Not been tested with KY jelly, anti-fungal creams. Intercourse should not affect.
Other testing being developed
Amniotic Fluid Testing With Nitrazene Paper
Collected with sterile swab via sterile speculum exam
Amniotic fluid is neutral (pH 7.0) or slightly alkaline (pH 7.25)
Changes the color of the yellow NitrazineNot a definitive test
Amnicators®
Nitrazine Test
Color pH Interpretation
Yellow 5.0
Olive 5.5 Probably not ruptured Olive-green 6.0 Blue-green 6.5 Probably are ruptured Deep blue 7.5 May be caused by
blood or cervical mucus
Fern Test
Obtain fluid sample on 2 swabs with sterile speculum exam (no lubricant) 1st slide from fluid pooled in spec blade, 2nd slide
from back of vagina below the cervixSpread onto clean slide by rotating top tip of
swab onto slide (hold swab vertical, not horizontal)
Allow to dry 5 to 7 minutesView under microscope on low power
Ferning
Positive ferning Negative ferning
Stages of Labor
First stage – 0 to 10 cmSecond stage – 10 cm to deliveryThird stage – delivery to placenta
First Stage (1st phase)
Latent or preparatory phase (0-3 cm)
Extends from onset of regular UCs to the beginning of the active phase when dilation occurs more rapidly
May be several hours, nearly flat line on graph
At end of latent phase, cervix is soft, well effaced, and dilated approximately 3 cm.
First Stage (2nd phase)
Active (dilatational) phase (4-7 cm) Sharp upswing in curve as rate of
dilation increases rapidly Effective labor begins w/this phase Phase of maximum slope – most
dilation occurs at this time 1.2 cm/hour average primips 1.5 cm/hour average multips
First Stage (3rd phase)
Transition, also called “Deceleration Phase” (7-10 cm)
Rate of cervical dilation slowsOccurs just before complete dilation;
phase may be short or not present at all
Active phase ends at complete dilation
Stages of Labor
Second stage (10 cm to birth) Normal up to 2 hours- primip, 1 hour
multip, add an hour if they have an epidural
Pushing stage Remember these are general guidelines;
pay attention to all influencing factors Third stage (placental delivery)
Normal up to 30 minutes
Friedman Curve (Can print from OBix)
First stage new research
“Recent data from the Consortium on Safe Labor have been used to revise the definition of contemporary normal labor progress.”
0.5 cm/h to 0.7 cm/h for nulliparous 0.5 cm/h to 1.3 cm/h for multiparous (the ranges reflect that at more
advanced dilation, labor proceeded more quickly)
First Stage New Research
“Recent data from the Consortium on Safe Labor have been used to revise the definition of contemporary normal labor progress.”
0.5 cm/h to 0.7 cm/h for nulliparous 0.5 cm/h to 1.3 cm/h for multiparous (the ranges reflect that at more
advanced dilation, labor proceeded more quickly)
First Stage New Research
“From 4–6 cm, nulliparous and multiparous women dilated at essentially the same rate, and more slowly than historically described. Beyond 6 cm, multiparous women dilated more rapidly.”
“Second, the maximal slope in the rate of change of cervical dilation over time (ie, the active phase) often did not start until at least 6 cm.”

Essential Forces of Labor
Original Model (3 P’s) Identified 3 things that were thought
to affect length of labor/type of delivery: Powers – contractions, abdominal
pressure from pushing Passageway – size, shape of pelvis,
ability of cervix to dilate and stretch Passenger – fetus (size, position of
head, presentation, gestation)
Expanded Model (1978 – 1996)
Added 2 additional P’s:Psyche (maternal)
Previous experiences, emotional readiness
Cultural/ethnic heritage Support systems
Positioning – will discuss later
13 Essential Forces of Labor(13 P’s that affect a woman’s L&D)
Internal physical forces – originate from within the woman:
Powers – UCs, a major internal forcePassageway – pelvisPassenger – babyPhysiology (other sensations)
Physiologic responses to intensity of labor (large muscle shaking, vomiting, etc.)
Internal Forces (cognitive/emotional)
Psychology of mother – ability of mother to influence her birth; “I knew I’d have a c/s”
Preparation by mother – prenatal classes, choosing provider, preparing home for new baby, birth plans, visualizing how they wanted the birth to be
Position of delivery – changing positions to help baby turn, help labor progress normally
External Forces
External forces – originating from outside the mother
Professional provider – some perceived to be “agents of control”; ability to advocate/support the patient
Place of birth – can affect labor by imposing external requirements; environment
Procedures – contribute to the feeling of control or lack of control over labor (enemas if not needed, continuous EFM, having to use bedpan). May make women feel powerless or humiliated
External ForcesPeople – women reported their labors being
affected by other people (office staff, friends, relatives, educators). Often provided support, distraction; some helpful, some non-helpful
Politics – societal influences that were external to woman but affected her labor experience; affects her self-esteem and confidence (interchanges between provider & nurse, etc.)
Pressure interface – decision-making; when involved in decision making, women were pleased with their birth experience. When not involved, felt things were “done to them”
Supporting the WomanIn Labor
Nursing Presence
Numerous studies show a sustaining human presence decreases the anxiety, pain, and fear a woman may experience during labor ↑ catecholamines from pain & anxiety reduce
uterine and placental blood flow, slow dilation rates
Nursing Support: Effect on Labor
Women with continuous labor support areless likely to: have regional analgesia have any analgesia/anesthesia give birth with vacuum extraction or forceps give birth by cesarean have a baby with a low 5-minute Apgar score report dissatisfaction or a negative rating of
their experience
Positioning in Labor
Nonphysiologic Positioning
Lying supine - reduction in cardiac output and UC intensity
Recumbent Position
A Western tradition for the convenience of the provider, began when women were hospitalized for childbirth pelvis tilted and fetus directed toward coccyx weight on coccyx/sacrum, restricts posterior
movement & ↓ pelvic outlet dimensions tightens perineum & narrows vaginal opening active phase 33% longer
Physiologic Positioning- Upright Positioning
Gravity adds 10-35 mmHg to UC pressureContractions less painful, more productiveFetus well aligned with angle of pelvisMay speed up labor if woman has been
recumbentMay increase urge to push Relieves back pain, good for backrubCan use any type of fetal monitoring
Physiologic Positioning
Standing/Leaning Restful, good for backrubs Curving or leaning forward creates a
C-shaped sacral curve instead of S-shaped curve, easier for fetus to negotiate
Can embrace partner, feeling of well-being & being cared for
Ambulating, Lunge Ambulating
Movement changes pelvic joints, enc. rotation
May provide distraction May ↑ woman’s sense of personal control
Lunge – “lunge” to one side Widens pelvis Encourages rotation of OP fetus Do for ~ 5 sec. at a time
Dangle - same effect
Can put foot up on chair, or just “lunge” to side and stand for short time
Lunge
Dangle Raise bed, remove
foot sectionPartner sits on bed,
woman’s weight supported on partner’s legs
During UC, woman relaxes & dangles
Lack of weight-bearing allows pelvis to shift/move to accommodate fetus
Pelvic Rocking
Movement should be small, try to keep back flat/straight & not curved towards floor
Encourages fetal descent & rotation, relieves pain
Sitting Position
UC’s more frequent, greater duration and intensity
Good resting positionSome gravity advantageFetal descent improves when upright 30
degrees or more (shorter 2nd stage)May assist with bearing down effortsVaginal exams possible, can use EFM or
auscultation
Sitting vs Recumbent
Primips: 1st stage 23% shorter, 2nd stage 48% shorter; less likely to have forceps
Multips: Active phase 42% shorter, 2nd stage no difference
Sitting Alternatives
Sitting, leaning forward
Relieves backache, good position for back rub
Opens pelvisRelaxes perineum
Birth Ball
Allows for pelvic rocking, bouncing
Semi-squat widens pelvis
Movement & distraction reduces pain – gives mom something to do during painful UC
Sitting: toilet/commode, birth stool
May relax perineum for effective bearing down
May feel more natural to push/bear down
Semi-squat position widens pelvis, shortens 2nd stage
Hands and Knees
Relieves back pain, pressure off sacrumAssists rotation of baby in OPAllows for pelvic rockingVaginal exams possiblePressure off of hemorrhoidsMay be used to correct FHR decelerationsRecommend H&K for 15 min., rest; repeat
The Occiput Posterior Baby (OP)
Back of baby’s head towards mother’s back
Linked with longer labors, delays dilatation and descent
Causes considerable back pain
OP Position & Back Pain
Change position q. 20-30 minutes to facilitate baby’s turning; take advantage of gravity & movement
Stand or walk to help align fetus in pelvis and ease rotation
Pelvic rockingCounter pressure, massageHeat/cold packsShowers with spray on painful areaHands & Knees (H&K)
H&K - Physiology
When mom flips, occiput no longer crowding the sacrum
Increases diameter of pelvisBack is heaviest part of the baby (like a
wooden boat) and as the uterus falls forward the angle between the uterus and spine increases
Gravity and buoyancy turn the fetal back, head will rotate & follow
Intact membranes helps rotation as more bouyancy
Study on H&K
100 healthy primips not in labor @ 38 wks with fetuses in OP position. Randomly divided into 5 groups of 20 per group:1 – H&K position2 – H&K with pelvic rocking3 – H&K w/mother stroking baby downward4 – H&K w/pelvic rocking & stroking5 – control group, no H&K
Results
Successful rotation to OA occurred in 12-18 of the 20 women in each of the 1st 4 groups No significant differences found between
the 4 methods (H&K only or w/some other action)
However, none of the fetuses in the control group rotated.
Study on H&KAnother study showed decreased back
pain along with trends toward a benefit for several other outcomes, including operative delivery, fetal head position at delivery, 1-minute Apgar scores, and time to delivery
Eleven women (16%) allocated to use hands-and-knees positioning had fetal heads in occipitoanterior position following the study period compared with 5 (7%) in the control group
Knee Chest
Modification of H&K, but tush is higher than shouldersBegin by getting into H&K and then
slowly lower head to comfortable resting position
Many same benefits as H&K, but less tiring on arms/wrists
Good resting position, good for counter-pressure or massage
Modified Knee-ChestHands & Knees
Side Lying
Good resting positionConvenient for many interventionsHelps lower blood pressureGreater UC intensity than when supineSafe if pain medications usedMay promote progress of labor when
alternated with walkingGravity neutralCan slow a very rapid second stage Easier to relax between pushing effortsAllows posterior sacral movement in 2nd
stage
Squatting
Tilts pelvis & uterus forwardHelps align fetus for enhanced rotation and
descent↑ strength of UCs (squat instead of pitocin!)Works with gravity for smooth descent of
babyEncourages dilation of cervixRelieves back pressureSupports abdominal muscles by placing
thighs pressure against abdomenShortens birth canal
Squatting
Relaxes & evenly stretches pelvic floor muscles
Reduces need for episiotomyDecreases need for forcepsShortens 2nd stageWidens pelvic outlet (0.5-2 cms) –
pelvic outlet 28% greater in squat position compared to side-lying
Allows freedom to shift weightRequires less bearing down effort and ↑urgePrevents supine hypotension
Comfort Techniques For Labor Support
Counter Pressure
Localized pressure to reduce back pain Steady strong force applied to a spot on
the low back during UCs using the fist, heel of hand, or a firm object
Other hand placed in front over hip bone to offset the pressure on her back
Mom should designate where the pressure feels best and amount of pressure to use
May gentle rotate/massage fist into area
Bilateral (Double) Hip Squeeze
Type of pressure massage that can relieve back pain, help open pelvic outlet
During labor, baby’s head stretches the pelvis; the hip squeeze helps to relax the
stretched musclesWoman in position where her hip
joints are flexed (hands/knees, standing and leaning forward, etc.)
Begin by placing hands on hip bones, then slide hands back
Double Hip Squeeze
Keep one hand on each bone and your thumbs pointed toward the spine forming a "W". Push the hipbones "in and up" towards the mothers body, and at the same time towards the mothers shoulders as if you needed to press on the bones and slide them up her back.
Steady pressure with the whole palms of hands (not heels of hands), directed diagonally toward the center of pelvis
Double Knee Press
Localized pressure to reduce back painWoman sits upright in chair with support
behind lower back, knees a few inches apart, feet flat
Partner kneels in front, cupping knees with both hands (heel of hand on top of tibia)
Steadily press knees straight back toward woman’s hip joints by leaning towards her duing UC
Can also be done with woman side-lying
Measures to Inhibit/Compete with Pain Awareness
Superficial Heat
Soothing, pain-relieving effects↑ uterine activity (local application of heat
to abdominal wall over upper uterine segment)
Hot compresses to groin, perineum Caution with heat of hot pack!
Warm blankets
Superficial Cold
Slows transmission of impulses over sensory neurons leading to decreased sensation/pain
Useful for musculoskeletal and joint pain (so back labor usually responds well to cold)
Ice packs on low back, anus, perineumTo perineum after birth to reduce swelling
Superficial Cold - Cautions
Protective layer should be placed between woman’s skin and source of cold
Don’t use if woman already chilled or shivering
Be aware of cultural variations, may have strong avoidance of cold
Hydrotherapy
Bath/shower ancient treatment for many ailments
Relaxing, stress reducingRelief of pain, enhanced blood flow to
exposed area, less use analgesiaMay accelerate labor, improved UCs
In 1 study, half as many in the bath required augmentation of labor
Decrease in BPHigh patient satisfaction
Physiologic Effects
Weight of water (hydrostatic pressure) moves tissue fluid into intravascular space ↑ plasma volume, cardiac output, urinary output In early labor, could slow labor (dilutes circulating
oxytocin)Causes vasodilation of peripheral blood
vessels, decreases BPBuoyancy reduces pressure on abdominal
muscles and decreases pain of UCs
Nursing Considerations
Water temp should be 96 – 98 degrees to prevent maternal hyperthermia and fetal tachycardia
Can remain in tub as long as desired unless clinical reason exists to leave tub (fetal distress, bleeding, advanced labor) Monitor fetus w/fetoscope or water-resistant
doppler or U/S toco (Note – toco NOT water-proof!)
Monitor maternal temperatureOkay w/ROM if fetal head engaged
Touch
Pat of reassurance, stroking – all signs of caring/comfortTouch or massage stimulates
different sensory receptors that can compete with pain receptors
Be sure to use “caring touch” in addition to “clinical touch”
Study: Clinical vs Caring Touch
Looked at work activities of OB nurses in a large teaching hospital
Detected only 2 instances of caring touch in 616 observations of work activities
Less than 10% of their activities were categorized as supportive; most were giving instructions or information to mom; touch for clinical work (take pulse, help with positioning, check cervix, apply/re-adjust EFM, etc.)
Massage
Firm or light stroking, vibration, kneading, deep circular pressure, continual steady pressure, joint manipulation
Stimulates variety of receptors in skin & deeper tissues
Hand massage easy to do, almost always accepted by laboring woman
Very soothing to women who grip their hands during labor
Nursing Presence & Teaching Education on what is happening & what to
expect – knowledge is power! Information on options Information on discomfort/sensation – what
to expect and what they can do about itWomen supported in labor have shorter
labors, require less pain meds, and more likely to have a vaginal birth
Positive affirmations You can do this, you’re doing great That’s one less contraction you’ll never see again
Continuous Intrapartum Support
Less likely to have intrapartum analgesiaLess operative birthLess likely to report dissatisfaction with
their childbirth experienceFewer perinatal complicationsFewer NBs with 5 min. apgar score < 7Fewer NBs admitted to NICUShorter labors
Distraction
Conscious mind-diverting activities can reduce pain Patterned breathing Visualization Concentration on a visual (focal point),
auditory, or tactile item
TENS (Transcutaneous Electrical Nerve Stimulator)
Non-invasiveLow voltage electric current
transmitted to skin with electrodes; buzzing or tingling sensation Don’t place electrodes on abdomen –
possible effects of TENS on fetal heart function; less concern on back
Can vary intensity, pulse frequency, & patterns of stimulation
Can ↑ intensity during UC, ↓ after UC
Intradermal Water Injections
For back pain in labor Equipment – sterile H20, TB syringe,
25 gauge needleTakes ~ 20-30 seconds to administer,
relief within 2-5 minutes, lasts 1-4 hours Can be repeated in 1-2 hours if needed
RN injects 0.1 ml sterile H20 intradermally at 4 sites
Mark injection sites. Find posterior iliac spines, palpated by
feeling the bony prominences just lateral to the sacrum and below the iliac crest; then measure 2-3 cm below and 1-2 cm medical from the spines
Swab sites with alcohol, inject 0.1 ml sterile H20 into each site, forming small bleb
Patient feels intense stinging, followed by relief of back labor
Birth Ball
During pregnancy, stimulates postural reflexes and keeps supportive muscles of spine in good working order.
Facilitates physiologic positions for laborEnhances labor through optimal fetal
positioning in relation to woman’s pelvis Encourages pelvic motion which aids
rotation of posterior babyPromotes squatting without knee strain
Allows mother to shift weight and support pelvic region for greater comfort during labor
Facilitate fetal descent when labor may not be progressing
Allows gravity to help with birthCan support a woman if she wants to try
different positionsAllows woman to move with supportProvides easy access to mother’s back for massage
Relieves nervous tension- provides comfort and relaxation for woman
Easy to useEasy to cleanVersatile- Can be used in bed,
shower, on floor, against wall or for partner support
Comfortable for postpartum use Babies enjoy bouncing and rocking
motion provided by Mom on birth ball
Birth Ball PositionsSitting
May gently rock side to side or back and forth
May gently bounce
Access to back for partner massage
Kneeling Kneel on pillow and lean over ball Sit on ball and lean over bed Place ball on bed, kneel in bed and
lean over ball
Leaning Position ball behind mothers back
against wall and mother leans back onto ball
Position ball on bed behind mothers back and mother leans into ball
Provides “piston” action
Peanut ball Position ball between legs (often used
with epidural) Frequent repositioning required Recent study showed 2 hour reduction
in length of labor, as well as decreased vacuum and forceps use
Mom should be barefoot or wearing non-slip socks when on ball
A spotter should always be near when Mom attempts to sit on the ball
When sitting down on the ball Mom should hold the ball with her hand as
she sits downFeet should be flat on the floor and
approx 2 feet apart to help stabilize her
Other considerations when using the Birth Ball:
Carrying strap should be removed when in use by Mom
Cover the ball when in use with towel, blanket, Chux pad for Mom’s comfort and for absorption
Birth ball covers are available and have a handle built in for ease in carrying. (I’m not sure how you clean these?)
Types of Birth BallsRound balls:

Peanut Balls Help provide positioning for bedrest
women May be usedto improve comfort and helpopen pelvis
The 3 “R’s” for Labor Pain Management
Relaxation
Rhythm breathing
Rituals
Relaxation
Psychological benefits Helps you to remain emotionally calm during labor You have more control and can communicate more
effectively with those around youPhysical benefits
Relaxed muscles use less oxygen, more O2 for you & baby
Uterus can contract more effectively Decreases fatigue Increases pain threshold Diverts focus to a positive action
Rhythmic Breathing
Benefits Helps laboring woman relax, especially if
she has learned/practiced the techniques (provide practice time in early labor)
Calming effect Provides measure of control for woman Can be used when other comfort measures
not available (i.e., unable to get up to shower or whirlpool, use birth ball, etc.)
Benefits of Breathing Patterns
May enhance oxygen to mom, uterus, baby
Provides distraction Brings purpose to contractions,
makes them more productive
Strategies to Use With Breathing
Count breathsUse light massage such as effleurageCount to 4 or 5 as you inhale and exhaleUse music via headphonesVisualize - close your eyes and "see" an
image, or place, that you find relaxingGet on all fours and rockWalk, rocking chair, birth ballHave a focal point (internal or external)
Strategies to Use w/Breathing
Sing a tune in your headUse repetitive phrase: "I am safe...I am
sound," "Breath in oxygen, breathe out tension.“
Stand and rock your pelvis from side to sideBath, shower, or whirlpoolChange the way you inhale/exhale Inhale/exhale through your nose Inhale/exhale through your mouth.
Other Strategies
Focal point – picture, partner’s face, tile on ceiling, etc. – helps to distract from UCs
Cleansing or relaxing breath – big sigh Helps you to signal your body to relax and
prepare for coming contraction Releasing breath at end helps get rid of
any lingering tension
Remember…
Even if they have been to Childbirth classes, they look to you to assist, coach, lead them
Be present for your patients and be an active participant in their labor and birth
Types of Breathing Patterns
The following are taught in prenatal classes: Slow paced breathing Slow modified paced breathing Modified paced breathing Patterned paced
Slow Paced Breathing
Start with relaxing breathSlow easy breaths in & out, ~ ½ normal
rate (in nose, out mouth; whatever most comfortable)
End with relaxing breathReview next breathing pattern with mom
prior to this pattern no longer working (i.e., prepare her for what is next)
Use until it is no longer working for mom
Slow Modified Paced
Start with relaxing breath Begin with slow paced breathing When the slow breathing doesn’t work,
speed up the breaths during the harder part of the UC
Slow to slow paced breathing when able End with relaxing breath
Modified Paced Breathing
Can use prior to Slow-Modified Paced (previous pattern) if works better for pt.
Start & end with relaxing breath Quick, shorter breaths throughout UC (~ 2x normal
breathing rate) In through nose, out through mouth may help prevent
hyperventilating
Modified Paced Breathing
Can use any combination of breathing patterns that work, various rhythms Breathing in & out with each word:
“HA-HA-HA-WHOOOO” “HE-HE-HE-WHOOOO”
Patterned Paced (Pant/Blow)
Relaxing breath pre & post UC Pant blow
Gentle Pushing
Relaxing breath pre & post UC Gentle bearing down with urge,
breathe as desired
Basic Patient Care Considerations
HydrationIV therapyChange soiled/damp linen promptlyFrequent mouth carePerineal careGood ventilation/fansControl the labor environment
Second Stage LaborManagement
2nd Stage Labor – 3 phases
Latent phase – time following full dilation until urge to push is established
Active phase – ↑ urge to bear down Fergeson’s reflex – presenting part
stretches pelvic floor muscles, causes release of endogenous oxytocin
Supports theory that urge to push is more dependent on station than dilation
Transition stage – begins when baby’s head bulges the perineum, crowns, and baby is born
Length of 2nd Stage
Efforts to limit length of 2nd stage have been documented since 1861
Rationale was to ↓ risk of hypoxia to fetus
Led to practices such as directed pushing; strong, sustained pushing; and pushing before urge to push
No research has been documented to support these practices
“Traditional” 2nd Stage
Breath holding Duration of labor not significantly different May lower pH and apgar scores
Valsalva maneuver ↑ intrathoracic pressure & intracranial pressure Impairs blood return from lower extremities,
results in ↓ in uteroplacental flow Can cause FHR decelerations Tightens pelvic floor muscles, may ↑ perineal
damage
Traditional Birthing
Lithotomy position, lying on back with legs up in stirrups – decreases maternal PaO2. Not found to occur if pushed in upright
positionIf women are in lithotomy & also hold their
breath when they push, risk of maternal & fetal PaO2 reduction increases When not instructed how to push, average
pushing effort lasted 5 seconds w/an average of 4.29 pushing efforts per contraction
“Count to Ten” Pushing
May create fetal hypoxemiaAlternate technique is to moan, create the
sound of “oh” or a deep humming sound with pushing May decrease interventions, improve fetal
status, decrease maternal fatigue, improve neonatal status
Rest prior to pushing if no urge (primips up to 2 hours, multips up to 1 hr) Fewer variable decels, less maternal fatigue,
decrease in pushing time, and trend towards higher apgar scores
2 Studies
Cohen (1977) found no significant ↑ in frequency of perinatal mortality or neonatal mortality when 2nd stage lasted longer ↑ in PP hemorrhage noted related to obstetric
interventions used to limit length 2nd stage
Study replicated in 1995, retrospective study over 5 years of 6,041 primips – no adverse outcomes found in closely monitored pts, even when 2nd stage exceeded 5 hrs in 2.7% of patients (Menticoglou, Manning, Harman, & Morrison)
Physiologic Second Stage “Laboring Down”
Urge to push may be at, before or after 10 cm
Don’t have patient push if no urge – can cause asynclitic presentation
Duration of labor not significantly different; directed pushing does cause negative changes in mother and fetus (apgars, lacerations, BP’s, etc.)
Upright Positioning
Benefits in 2nd stage similar to 1st stage – improves uterine contractility, reduced muscle hypoxia, reduced pain
Less perineal trauma, fewer episiotomiesHigher fetal oxygenation saturation
during labor; higher pH & pO2 and lower pCO2 levels at birth for newborns
Squatting
Best position for 2nd stage laborUterus elevates, directing fetus
towards pelvic outlet, fetal descent enhanced
Golay, Vedam, Sorger (1993) – mean length of 2nd stage shortened by 23 min. for primips and 13 min. for multips who pushed while squatting compared to women who pushed in semi-recumbent position
Pharmacologic Pain Control in Labor
Medications - various oral, IM, or IV meds depending on stage of labor and desired effect
EpiduralIntrathecal Narcotics
Sedatives/ Tranquilizers
Decrease anxiety, inhibit contractions, allow rest or sleep
Use only in early labor due to possible negative maternal/neonatal effects
Does not help for painCan be given with opioids or narcoticsSeconal, NembutalPhenergan, Vistaril, Largon

FHR variability may decrease IV/IM or combination IV onset 5-10 minutes, IM onset 20-40
minutesDuration 2-4 hoursGive all IV meds at beginning of UC when
blood vessels of uterus & placenta are constricted; minimizes drug transfer to fetus
