Fetal position - Three letter designation
1) Side of pregnant patient that the baby’s body part is leaning toward - L or R
2) Baby’s body part entering the pelvis -Occiput, Sacrum, Scapula, Mentum

Good contractions are every __________ minutes and last __________ seconds.
Good contractions are every 2-3 minutes and last 60-90 seconds.
How can you check the frequency/duration/intensity of contractions?
Palpate the fundus
IUPCD- intrauterine pressure catheter
No cervical change (from previous dilation/effacement)
CTX do not intensify and may space out
Can walk/talk through CTX, walking does not make them stronger
Pain medication may stop contractions (Braxton Hicks)
False labor
Cervical change
CTX get longer, stronger, closer together, & demand attention
Walking may make them stronger
Pain med may slow or speed up labor, never stop
5-1-1
True labor
What is 5-1-1?
Occurring every 5 minutes
Lasting 1 minute
Happening for 1 hour
Signs of impending labor
lightening- baby dropped, irregular contractions (braxton hicks), energy spurt (nesting), increased urinary frequency, bloody show/vaginal discharge, loss of mucus plug, pelvic pressure (mom feels the urge to poo)
Maternal response to labor
Cardiovascular system- increased BP
Respiratory system- hyperventilation, O2 consumption increased during 2nd stage of labor; use mask (not nasal cannula)
GI system- digestion slows/stops during labor; no eating during labor
PMI
Point of Maximum Intensity
Use Leopold’s maneuvers to determine fetal presentation and find PMI. This is where you place the
fetal monitor
Vaginal exam determines
dilation, effacement, fetal station/decent, and amniotic membrane/fluid status
Diameter across opening
cervical dilation
0-10cm
Percentage of ‘shortening’
cervical effacement
0-100%
Document anything 50% or greater
Descent of the fetal presenting part in the pelvis in relation to ischial spines
Pelvic/fetal station
-5 to +5
Cervical exam example:
3/90/-1
3cm dilated
90% effaced
@ -1 station
COCA
color- pale, straw colored; flecks of lanugo or vernix
odor- no odor
consistency- watery
amount- 1,000 mL around 32-36 weeks; starts to drop at 37 weeks to 700-800 mL
If there is an odor when assessing amniotic fluid, indicative of an
infection
SROM
Spontaneous rupture of the membranes
AROM
Artificial rupture of the membranes

-Three phases- latent, active, transition
1st stage
Three phases of true labor (1st stage)
latent (early), active, and transition

latent (early)
4-7cm w/ moderate to strong contractions is what phase of true labor?
active
8-10cm w/ strong contractions is what phase of true labor?
transition
SVE
Sterile vaginal exam

Avoid infection
Nursing assessments/interventions during 1st stage of labor
-continuously monitor pain
-palpate contractions every 30 minutes (every 15 minutes during transition phase)
-EFM monitoring (intermittent if low risk/reactive, continuous if high risk/abnormal)
-SVE
-amniotic fluid @ROM (COCA, check FHR)
-assist w/ breathing
-encourage support
-prevent early pushing
-notify provider of any deviations/once 1st stage is complete
-administer medications
-document!
What stage of labor?

-“Pushing” stage
-End with delivery of baby
-duration may vary between primiparas and multiparas
2nd stage of labor
Nursing assessments/interventions during 2nd stage of labor
-maternal & fetal assessment

-remove foley if pt has an epidural
-promote effective pushing/positioning
-assist w/ delivery
-document!
Body preparation for birth during 2nd stage of labor
-bulging of perineum and rectum
-flattening and thinning of the perineum
-increased bloody show
-labia begins to separate
-burning sensation (Ring of Fire)
-intense pressure in rectum
-crowning
Types of lacerations
perineal, vaginal & urethral, cervical, and episiotomy
Episiotomy lacerations
-Median “midline”
-Mediolateral
Perineal laceration - 1st degree
First degree: Skin and structures superficial to muscles
Perineal laceration - 2nd degree
Second degree: Through muscles of perineal body
Perineal laceration - 3rd degree
Third degree: Through anal sphincter muscle
Perineal laceration - 4th degree
Fourth degree: Anterior through rectal wall
Rooter to the tooter
What stage of labor?
-Begins with birth of baby
-Ends with delivery of placenta
-Duration may last up to 30 minutes
Longer may lead to D&C due to retained placenta
-Signs that placenta is ready to deliver:
Lengthening of the cord, Gush of dark red blood (which appears after separation), Globular shape of abdomen, Patient feels “like I have to push again”
3rd stage of labor
Preparation during 3rd stage of labor
-APGAR on infant @1min, 5min, & 10min (if low score)
-watch for signs of placental separation (should occur within 30 min)
-vital signs
-baby to chest/warmer to prevent heat loss
-get lidocaine/sutures if episiotomy/laceration is present
-admin pitocin to prevent hemorrhage
-document after placenta delivers!
What stage of labor?
-May last up to 4 hours or more
-Physiologic readjustment begins
-Critical assessments by RN are done
-Fundal assessment is crucial!
Recovery stage
Three Sources of Labor Pain
-Emotional: fear, tension, and pain
-Functional: dilation and contractions
-Physiologic: maternal and fetal position
PAIN
Purposeful
Anticipated
Intermittent
Normal
Pain is serving a useful purpose, is a normal process. (not from illness or injury). Can be anticipated and prepared for with clear ending point.
Pain management in Labor
Nursing Goal
Continually assess fetus and client to ensure a safe delivery, facilitate a positive birth experience, assist in the management of pain, advocate for patient needs (patient needs may change throughout labor).
Types of non-pharmacologic pain relief
Hydrotherapy, birthing ball, peanut ball, cub, paced breathing & relaxation, music, guided meditation, guided imagery, aromatherapy, acupressure/counterpressure/massage, yoga, application of heat & cold
Warm water promotes comfort & relaxation
Showering or soaking in a tub or whirlpool bath
Helps decrease muscle tension
Buoyancy in tub can help with relief, increases oxytocin and endorphins
Hydrotherapy
Diminishes stress, anxiety, and tension (all which can increase sensation of pain)
When tension is reduced, patient breathes more deeply which improves oxygenation
Paced breathing & relaxation
Picture a place that is special or focus on a place where client likes to be
Nurse or labor support person can verbalize sights and sounds of the place to distract the client
Guided imagery
Use of essential oils
Rose, lavender, frankincense, and bergamot oils
Promote comfort and relaxation, decrease pain
May add to bath, to lotions, or use aromatherapy delivery device
aromatherapy
Can warm washcloths be applied to the perineum to help relieve discomfort from stretching and may help prevent tearing?
yes
Benefits of Non-Pharmacologic Pain Relief
No limitations to mobility during labor and after delivery
Fastest recovery (for both patient and baby)
Facilitates partner participation
Minimal intervention
A form of massage involving a circular stroking movement made with the palm of the hand.
Gentle strokes
Effleurage
Injection route IV or IM
Parenteral Analgesia
Analgesia
pain relief
True or False
Assessment should be completed prior to medication administration
True
Check maternal BP, fetal HR, and labor stage.
The safest and most effective form of pharmacological pain relief depends on
Stage of labor, progress of labor, medical status of client and fetus, and patient preference
Can non- pharmacological interventions for pain control be used in addition to pharmacological agents as labor progresses?
Yes, can promote relaxation and potentiate effects of meds
True or False
Opioids must be administered either more than 4 hours before delivery or less than 1 hour before delivery.
True
Advantages of Parenteral Analgesia
-Ease of administration
Dose can be titrated, Pain relief begins in minutes, No loss of consciousness, Increased relaxation, Decreased pain
-RN can administer
No waiting for anesthesia!
Antiemetics are used for
nausea/vomiting
Ex: Zofran, Phenergan-Opioid Catalyst
Opiate antagonist are used to
reverse opioid
Ex: Naloxone (Narcan)
Opioid agonists/Opioid agonist-antagonists provide
Intermittent Relief: reduce the awareness of pain
Ex: Butorphanol (Stadol) IV/IM
Meperidine hydrochloride (Demerol) IV/IM
Hydromorphone hydrochloride (Dilaudid) IV/IM
Nalbuphine (Nubain) IV/IM
Disadvantages of Parenteral Analgesia
Maternal response- may not relieve pain, cause N/V & drowsiness, confined to bed, continuous EFM
Fetal response- CNS depression (decreased FHR variability), respiration depression, decreased refluxes (sucking), can impair early breastfeeding, decreased ability to regulate temperature
-Colorless, odorless gas that is mixed 50/50 Nitrous oxide/oxygen for laboring moms
-Valuable alternative to epidural anesthesia
-When breathed in, it reduces anxiety and increases feelings of relaxation and well-being
-Inhaled though a mask or mouthpiece
-Can utilize at any stage of labor/delivery
Nitrous oxide
Advantages & disadvantages of nitrous oxide
Advantages: Does not impair patient mobility, No additional monitoring required, Self-administration provides patient with control, Medication effects stopped as soon as the mask or mouthpiece is removed
Disadvantages: Nausea and vomiting, Dizziness, Drowsiness
Safety concerns when using nitrous oxide
Risk of respiratory depression when combined with opioids
Rapidly crosses the placenta
Three types of anesthesia
Local, regional, and general
What type of anesthesia is used for episiotomy/laceration & repair?
local
Ex: lidocaine
Given immediately before birth for episiotomy or after birth for repair of lacerations
Types of regional anesthesia
-Epidural (Bupivicaine/Fentanyl on PCA Pump)
The epidural space is located between the dura mater and the ligamentum flavum.
-Spinal Intrathecal opioids (Duramorph)
Spinal anesthetic agent is administered into the CSF in the subarachnoid space.
When is general anesthesia used?
stat Cesarean (C-Section), other emergencies
Most commonly used method of pain control during labor (nearly 2/3 of women in US)
Epidural
