Complication of Intrapartum
Labor is a natural process,
but one faced with many
• Definition:Dystocia, or difficult
labor, abnormal 5P in labor.
1. Power; uterine contraction
2. Pathway; pelvis, cervix, birth canal
3. Passenger; fetus, placenta
4. Psychology; maternal fear and anxiety
5. Position; maternal birthing position
1. Power ; Contraction
1. Contractions that are not strong enough or frequent enough to
produce a normal labor pattern will not result in dilatation and
effacement within a normal time frame.
2. Problems with the force of labor will result in ineffective
contractions or ineffective bearing down (pushing) during the
second stage of labor.
3. Etiology of abnormalities in the force of labor include:
a. Early or excessive use of analgesia
b. Overdistention of the uterus
c. Excessive cervical rigidity
d. Grand multiparity
e. Mild pelvic contraction
f. Postmature and large infants
2. Passageway abnormalities
1. Problems in the pelvis or soft tissues of the reproductive tract.
2. Most often problems with the passageway are a result of pelvic abnormalities
that interfere with the engagement, descent, and expulsion of the fetus.
a. The size and shape of the pelvis is important.
b. Obstruction may result from problems of the soft tissue such as a uterine or
3. Contractions of the inlet are noted when the anteroposterior diameter is less
than 10 cm
4. Midpelvic contractions occur when the distance between the ischial spines is
less than 9 cm.
5. A contracted pelvic outlet is diagnosed when the distance between the ischial
spines is less then 8 cm.
When the pelvis is contracted and the fetus cannot fit through the
pelvis, CPD(cephalo-pelvic disproportion) exists.
3. Passenger; Fetal abnormalities
1. Normal fetal passage
a. Normally the fetus enters the pelvic inlet transversely and
then rotates to an occiput anterior position, allowing for the
smallest diameter of the fetal head to pass through the pelvis.
b. When the fetal head enters the pelvis posteriorly, it must
rotate to the anterior position.
3. If the fetus does not turn, then it remains in the posterior
position and may slow down the progress of descent.
a. If the pelvis is large enough, the baby can be born in the
b. If the pelvis is borderline and the contractions ineffective, a
Cesarean section may be necessary.
3.Passenger; Fetal Abnormalities
4. Breech presentations occur in approximately 3% of all
a. This presentation is more common in multiple
gestations, increased parity, hydramnios, placenta
previa, and preterm infants.
b. Usually the method of choice for delivery is a
5. Shoulder presentation occurs when the infant lies
crosswise in the uterus. The infant is delivered by
6. A large infant may not fit through the pelvis and CPD
4. Maternal psychology
• Maternal fear, anxiety influenced cervical
dilatation and adequate tissue perfusion.
• Fear anxiety catecholamine hormone
release vasocontraction ineffective
perfusion to fetus fetal distress
• Fear anxiety catecholamine hormone
release ineffective cervical dilatation and
maternal exhausted prolonged labor
5. Maternal Position
• Up right position; using gravity
• Lie down position; supine hypotensive
1. Inadequate progress of cervical effacement, dilatation, or
descent of the presenting part as determined by vaginal
2. Evaluation of labor progress by recording and assessing serial
vaginal examinations using Freidman's curve
a. Using Freidman's curve, a prolonged latent phase in the
primigravida is greater than 20 hours and in the multigravida it
is greater than 14 hours.
b. During the active phase, the cervix of a primigravida will
normally dilate at least 1.2 cm/h, and the multigravida 1.5 cm.
c. The fetus should be descending through the birth canal. In
the primigravida the rate of descent is 1 cm/h and 2 cm/h for
1. Treatment for contraction abnormalities involves
stimulation of labor through the use of oxytocin. An
intrauterine pressure catheter may be used.
2. Management for maternal passageway or fetal
passage problems(CPD) involves delivery in the
safest manner for the mother and fetus.
a. If the problem is related to the inlet or
midpelvis, a cesarean delivery is indicated.
• b. If the size of the outlet is the problem, a
forceps/vacuum/C-section delivery is usually

• Hydramnios (polyhydramnios) is caused by
an excessive amount of amniotic fluid.
• Normal amnionic fluid; 500-1200cc
• Hydramnios (polyhydramnios) 2000cc over
• Oligohydroamnios less then 300cc
• The amount of amniotic fluid present is
controlled in part by fetal
urination, swallowing, and breathing.

1. Depends on the severity of the condition and the
cause; hospitalization is indicated for maternal distress
or for intervention regarding fetal prognosis.
2. If impairment of maternal respiratory status
occurs, amniocentesis for removal of fluid may be
a. The amniocentesis is performed under ultrasound for
location of the placenta and fetal parts.

Preterm Premature Rupture of
Premature Rupture of
• Preterm(premature) rupture of membranes
(PROM) is defined as rupture of the
membranes before the onset of
• Normally spontaneous membranes
rupture(break) end of 1st stage or
beginning of second stage.
Preterm Premature Rupture of Membranes:
When the water bag breaks before 37
weeks of pregnancy AND labor has not
Premature Rupture of Membranes:
When the water bag breaks before the
start of labor.
1. The exact etiology of PROM is not clearly understood.
2. In preterm PROM, risk factors include:
b. Previous history of PROM
d. Incompetent cervix
e. Multiple gestation
f. Abruptio placentae
3. PROM is manifested by a large gush of amniotic fluid or
leaking of fluid per vagina, which usually persists.

presence of amniotic fluid taken from the
Amniotic fluid; alkali
1. Once PROM is confirmed, the woman is admitted to the
hospital and usually remains there until delivery.
2. The woman is evaluated to rule out labor, fetal
distress, and infection and to establish gestational age. If
all factors are ruled out, the woman is managed
3. For PROM, tocolytics, corticosteroids (to decrease the
severity of respiratory distress syndrome in the
premature neonate) and prophylactic antibiotics are
used, but remain controversial.
4. Management of PROM at 36 weeks' gestation or greater
focuses on delivery.
5. Vaginal examinations are kept to a minimum to prevent

them every 1 to 2 hours as indicated.
2. Monitor the amount and type of amniotic fluid
that is leaking and observe for purulent, foulsmelling discharge.
3. Evaluate daily CBC
4. Evaluate fetal status every 4 hours or as
indicated, noting fetal activity and heart rate.

2. Do not perform vaginal examinations without consulting the
primary health care provider.
3. Place patient on disposable pads to collect leaking fluid and
change pads every 2 hours or more frequently as needed.
4. Review the need for good hand washing technique and hygiene
after urination and defecation.
5. Monitor fetal heart rate and fetal activity every 4 hours or as
6. Monitor maternal temperature, pulse respiration, blood pressure,
and uterine tenderness every 4 hours or as indicated.
PROLAPSED UMBILICAL CORD
A prolapsed umbilical cord slips in front of or
alongside the fetal presenting part.
Types of cord prolapse include:
▪ Complete—the cord can be felt on vaginal
examination and be seen in the vaginal canal.
▪ Occult—the cord cannot be felt on vaginal
examination or be seen. The cord lies between the
presenting part and the maternal pelvis. Changes
in the fetal heart rate are evident.
▪ Forelying—the cord can be felt on vaginal
examination, but cannot be seen. The cord lies in
front of the presenting part.
A fetal cord prolapse may occur when there is
adequate room between the fetal parts and the
maternal pelvis. Predisposing factors include:
1. Rupture of membranes, when the presenting part
is not engaged in the pelvis
2. More common in shoulder and foot presentations
3. Prematurity—small fetus allows more space
around presenting part
4. Hydramnios—causes greater amount of fluid to be
released with greater force when membranes

Very young or very old
• The focus of treatment is prevention of
delivery of a preterm infant.
• The method depends on the cervical
dilatation and contraction pattern.
• If contractions are detected early and
treatment is begun early, there is a higher
rate of stopping labor.
• Treatment Approaches
If preterm birth is
mother steroids( at
least 48 hours before
birth can significantly
help the baby breathe
B. Tocolytic Therapy
• If conservative therapy is not
successful, tocolytic therapy is instituted.
These drugs should be used only when the
potential benefit to the fetus outweighs the
1. Prematurity and associated neonatal
complications, such as lung immaturity
A. Anxiety related to medication and fear of
outcome of pregnancy
B. Diversional Activity Deficit related to
prolonged bed rest
A. Decreasing Anxiety
1. Provide accurate information on the status of
the fetus and labor (contraction pattern).
2. Allow the woman and her support person to
verbalize their feelings regarding the episode
of preterm labor and the treatment.
3. If a private room is not used, do not place the
woman in a room with a woman who is in
labor or who has lost an infant.
4. Encourage relationship with other patients
B. Promoting Diversional Activities
1. Determine quiet craft activities that can be
done in bed.
2. Provide radio, books, and television.
3. Encourage visits from family, especially other
children and friends. If possible encourage
them to bring in favorite foods for the woman
and to dine as a family.
4. Encourage other family activities, such as
helping with homework. This will assist on
maintaining the family unit.
1. Educate the woman about the importance of
continuing the pregnancy until term or until there is
evidence of fetal lung maturity.
2. Encourage the need for compliance with a
decreased activity level or bed rest, as indicated.
3. Teach the woman the importance of proper
nutrition and the need for adequate hydration, at
least 8 glasses of fluids a day.
