Labor and Delivery Care: The Four Stages: Fatemeh Ahadi Yulghunlu
Abstract
In labor and delivery care, we need to have a single and broad view of the total
process of labor, delivery, and neonate birth. Key considerations during labor include
the four “P’s”: power, pass, passenger, and psyche. These elements are vital for
assessing the effectiveness of contractions, the passage through the birth canal, and
the condition of the fetus, respectively. Continuous monitoring of the fetal heart rate
is also crucial to ensuring the well-being of the unborn child throughout the labor
process. Also, in delivery care, recognizing the time of completion of the second stage
and preparing the mother for pushing and paying attention to the descent of the fetus
and the need to perform an episiotomy and finally the birth of the neonate. All these
steps require a systematic approach, and it is predetermined that we know the normal
process to recognize the abnormal cases and take the correct action.
Keywords: midwifery care, labor care, delivery care, progress of labor, fetal monitoring
1. Introduction
1
Labor and Delivery from a Public Health Perspective
Labor is defined by intense and painful uterine contractions that facilitate cervi-
cal dilation and enable the descent of the fetus through the birth canal. However,
significant preparatory processes occur in both the uterus and cervix well in advance
of this stage. Throughout the initial 36–38 weeks of a typical gestation period, the
myometrium remains in a preparatory state, characterized by unresponsiveness.
Simultaneously, the cervix initiates an early remodeling phase while preserving its
structural integrity. Following this period of uterine quiescence, a transitional phase
commences, during which the myometrium’s unresponsiveness is temporarily lifted
and the cervix undergoes processes of ripening, effacement, and a reduction in
structural cohesion [5].
The first stage of childbirth includes two phases:
2.1 E
arly labor
Early labor, also known as the latent phase, is the initial part of the first stage.
During this phase, the relaxation of the uterus is disrupted, the cervix becomes soft,
and the receptors in the myometrium wall of the uterus respond to uterotonics. Then
contractions begin to occur at regular intervals, although they are usually mild and
may not be very painful. The cervix starts to soften, thin out (efface), and dilate up
to 6 centimeters. This phase can last for several hours to days, especially for first-time
mothers [6].
During early labor, it is common for women to experience a range of symptoms,
including:
• A clear or slightly bloody discharge from the vagina, known as the mucus plug.
To manage discomfort during early labor, women are encouraged to stay active,
practice relaxation techniques, and stay hydrated. Many women spend this phase at
home until contractions become more intense and frequent [7].
The following strategies may be effective in managing labor pains and associated
discomfort:

• Maintain adequate hydration: Ensure that you are consuming sufficient fluids
and consult with your healthcare provider regarding the appropriateness of light
eating or the necessity of fasting during this period [8].
2.2 A
ctive labor
Active labor is the second phase of the first stage and is marked by more intense
and frequent contractions. During this phase, the cervix dilates from 6 to 10 centime-
ters. Contractions become stronger, closer together, and more regular. This phase is
typically shorter than early labor but can still last several hours [10].
As active labor progresses, women may experience:

idwifery care
This section documents the woman’s name along with essential information neces-
sary for assessing her baseline characteristics and risk status upon admission for labor.
Additionally, pertinent demographic and labor-related factors, including the woman’s
age, gestational age, serological results, hemoglobin levels, blood type and Rh factor,
referral status and rationale, and symphysis-fundal height, should be incorporated
into the woman’s medical record [3].
Table 1 shows how to assess the variables discussed in this section, as well as the
appropriate manner for documenting the acquired information [3].

onmedical methods
3. Water therapy: Taking a warm bath or shower can relax muscles and reduce pain.
Hydrotherapy has been found to decrease pain intensity and improve satisfaction
with the childbirth experience [13].
4. Massage and counter pressure: Having a partner or doula apply pressure to your
lower back or massage tense areas can provide significant relief. Evidence sug-
gests that massage can reduce labor pain and anxiety [14].
2.4.1.2 M
edical methods
1. Epidural analgesia: This is a common and effective method for pain relief during
labor. It involves injecting anesthetic near the spinal cord to block pain. Studies
show that epidurals provide significant pain relief and are safe for both mother
and baby [15].
2. Nitrous oxide: Also known as laughing gas, this can be inhaled during contrac-
tions to reduce pain and anxiety. Research supports its effectiveness and safety
for pain management during labor [16].

hecking the progress of labor
Monitoring the progress of labor is essential to ensuring the health and safety
of both the mother and the baby. Here are some key methods used to check labor
progress:
2.4.2.1 C
ervical dilation and effacement
• Effacement: This refers to the thinning of the cervix, measured in percentages from
0–100%. Complete effacement (100%) means the cervix is fully thinned out [1].
2.4.2.2 C
ontraction monitoring frequency and duration
2.4.2.3 F
etal descent station
This measures the position of the baby’s head about the mother’s pelvis, ranging
from −3 (high in the pelvis) to +3 (crowning). A positive station indicates the baby is
moving down the birth canal [22].

se of partogram
Graphical tool: A partogram is a chart used to plot the progress of labor, including
cervical dilation, fetal heart rate, and contraction patterns. It helps in identifying any
deviations from the normal labor progression [24].
Imaging techniques: Ultrasound can be used to assess fetal position, amniotic fluid
levels, and other factors that might affect labor progress. It provides a noninvasive
way to monitor labor [25].
2.4.2.7 M
aternal vital signs
Monitoring health: Checking the mother’s blood pressure, pulse, and tempera-
ture helps ensure her well-being during labor. Abnormal vital signs can indicate
complications [1].
In general, the four Ps are important in checking the progress of labor, which
include four Ps (power, passenger, passage, and psyche).
Labor progress is determined by assessing the four following components, also
known as the four Ps:
1. Power: The term “power” pertains to the intensity of uterine contractions and
the maternal efforts to expel the fetus during the second stage of labor. This
aspect is evaluated through abdominal palpation. Contractions that contribute
to normal labor progression should exhibit regularity, frequency, a duration
exceeding 60 seconds, and facilitate cervical effacement.
2. Passenger: This pertains to the evaluation of the fetus, specifically regarding its
size, position, and attitude, which refers to the spatial relationship among the

3. Passage: The anatomy of the bony pelvis must be evaluated in conjunction with
soft tissue elements, including the existence of a distended bladder or rectum,
any occupying masses, or the presence of vaginal septa. The assessment of pelvic
adequacy can only be conducted during the process of labor.
4. Psyche: This analysis acknowledges the significance of the mother’s emotional state
during labor, which can influence the overall progression of the labor process. Key
factors to evaluate include the levels of stress and underlying anxiety experienced
by the mother, the presence of sufficient support from a birthing partner, and the
establishment of a welcoming and supportive environment for the woman [24].

Monitoring the fetal heart rate (FHR) during labor is crucial for assessing the
baby’s well-being and ensuring a safe delivery. Here are the key methods and their
importance [27].

• External monitoring: Involves placing two belts around the mother’s abdomen.
One belt uses Doppler ultrasound to detect the fetal heart rate, while the other
measures contractions.

other’s emotional needs
Addressing the emotional needs of mothers during labor is crucial for a positive
childbirth experience. Here are some key aspects to consider:
1. Emotional support
• Respectful care: Ensuring that the mother is treated with respect and dignity
throughout labor is essential. This includes maintaining her privacy, obtaining
informed consent, and respecting her birth plan [32].
• Clear communication: Keeping the mother informed about the progress of labor
and any procedures being performed helps reduce fear and uncertainty [33].
4. Physical comfort
• Mobility and positioning: Allowing the mother to move around and choose
comfortable positions during labor can help reduce discomfort and improve
labor progress.
5. Psychological support
Meeting the emotional needs of mothers during labor is essential for a positive and
empowering childbirth experience. Providing continuous support, respectful care,
effective pain management, clear communication, physical comfort, and psychologi-
cal support can significantly enhance the overall experience for both the mother and
the baby.
The second stage of labor begins when the cervix is fully dilated to 10 centimeters
and ends with the birth of the baby. This stage is crucial as it involves the actual
delivery of the baby through the birth canal [35].
1. Transition to birth: This stage marks the transition from labor to the birth of the
baby. It is characterized by strong and regular contractions that help push the
baby down the birth canal [36].
2. Maternal and neonatal outcomes: Proper management of this stage is vital for
minimizing maternal and neonatal morbidity and mortality. A prolonged second
stage can increase the risk of complications such as fetal distress and maternal
exhaustion [37].
1. Monitoring: Continuous monitoring of the fetal heart rate and maternal vital
signs is crucial to ensuring the well-being of both mother and baby. This helps in
early detection of any signs of distress [39].
2. Support and guidance: Providing emotional and physical support to the mother
is essential. Encouraging words, helping with breathing techniques, and offering
comfort measures such as changing positions can make a significant difference [40].

Labor and Delivery from a Public Health Perspective
3. Pushing techniques: Guiding the mother with effective pushing techniques can
help shorten the duration of the second stage and reduce the risk of complica-
tions. It is important to follow the mother’s cues and allow her to push when she
feels the urge [41].
1. Prolonged labor: This occurs when the second stage of labor lasts longer than
expected. Prolonged labor can increase the risk of maternal and fetal complica-
tions, including infection, postpartum hemorrhage, and the need for assisted
delivery or cesarean section [43].
2. Fetal distress: This is a condition where the fetus does not receive adequate
oxygen during labor, leading to abnormal heart rate patterns. Fetal distress can
necessitate immediate interventions such as an emergency cesarean section [44].
3. Shoulder dystocia: This is a rare but serious complication where the baby’s shoul-
der gets stuck behind the mother’s pelvic bone after the head has been delivered.
It requires prompt and skilled management to prevent injury to both the mother
and baby [45].
4. Perineal trauma: Tears or lacerations to the perineum (the area between the va-
gina and the anus) are common during the second stage of labor. Severe tears can
lead to significant pain, bleeding, and long-term complications such as inconti-
nence [42].
6. Maternal exhaustion: Prolonged pushing and labor can lead to significant physi-
cal and emotional exhaustion for the mother, impacting her ability to effectively
participate in the delivery process [47].
In summary, the second stage of labor is a critical phase that requires careful man-
agement and support to ensure a safe and positive birth experience for both mother
and baby. Midwifery support is crucial during the second stage of labor, as it can
significantly impact the mother’s experience and the outcome of the birth. Midwives
provide both physical and emotional support, helping to ensure a safe and positive
birthing experience [18].

The third stage of labor begins immediately after the birth of the baby and ends
with the delivery of the placenta. This stage is crucial for ensuring the health and
safety of both the mother and the newborn [1].
1. Placental separation and delivery: The primary event in this stage is the separa-
tion and expulsion of the placenta from the uterine wall. Proper management
is essential to prevent complications such as retained placenta and excessive
bleeding [48].
3. Uterine contraction: After the placenta is delivered, the uterus must contract to
close off blood vessels and prevent hemorrhage. Ensuring strong uterine con-
tractions is vital for minimizing blood loss [48].
1. Active management: Active management of the third stage of labor (AMTSL) in-
volves administering a uterotonic drug (usually oxytocin) immediately after the
birth of the baby to stimulate uterine contractions and reduce the risk of PPH.
This approach has been shown to decrease the incidence of severe hemorrhage
and the need for blood transfusions [50].
The important causes of postpartum bleeding can be summarized as four (T) [1]:
• Tonicity (uterine atony after childbirth due to various causes such as long
induction of labor, maternal obesity, and multiparity)
3. Cord clamping: Delayed cord clamping (waiting 1–3 minutes after birth) is rec-
ommended to improve neonatal outcomes, including increased iron stores and
reduced risk of anemia in the infant [1].
11
Labor and Delivery from a Public Health Perspective
In summary, the third stage of labor is a critical period that requires careful
management to ensure the health and safety of both the mother and the newborn.
Active management, continuous monitoring, and providing emotional support are
key components of care during this stage.
5. F
our stages of labor
The fourth stage of labor, also known as the recovery stage, begins immediately
after the delivery of the placenta and lasts for about two hours. This stage is crucial
for monitoring the mother and ensuring that both she and the newborn are stable and
healthy.
1. Monitoring for complications: This stage is critical for identifying and manag-
ing any immediate postpartum complications, such as postpartum hemorrhage,
uterine atony, or retained placental fragments [54].
3. Maternal and neonatal bonding: The fourth stage provides an opportunity for
skin-to-skin contact between the mother and the newborn, which promotes
bonding, stabilizes the baby’s temperature, and encourages breastfeeding [55].

are during the fourth stage of labor
5. Perineal care: If the mother experiences any perineal tears or had an episiotomy,
proper care and assessment of the perineal area are necessary to prevent infec-
tion and promote healing [58].
In summary, the fourth stage of labor is a critical period that requires careful
monitoring and support to ensure the health and well-being of both the mother and
the newborn. Effective management during this stage can help prevent complications
and promote a positive postpartum experience.
6. Conclusion
The process of labor is divided into four distinct stages, each with its signifi-
cance and required care to ensure the health and safety of both the mother and the
newborn.
• First stage of labor: This stage involves the onset of labor and the dilation of the
cervix. Proper monitoring and support during this stage are crucial for managing
pain and ensuring the progress of labor.
• Second stage of labor: This stage begins with full cervical dilation and ends with
the birth of the baby. Effective pushing techniques, continuous monitoring,
and emotional support are essential to facilitate a safe delivery and minimize
complications.
• Third stage of labor: This stage involves the delivery of the placenta. Active
management, including the administration of uterotonic drugs, is important
to prevent postpartum hemorrhage and ensure the complete expulsion of the
placenta.
• Fourth stage of labor: Also known as the recovery stage, this period focuses on
monitoring the mother and newborn for any immediate postpartum complica-
tions. Providing emotional support, pain management, and assistance with
breastfeeding are key components of care during this stage.
Each stage of labor requires specific care and attention to ensure a positive and
safe birthing experience. Continuous monitoring, effective pain management, and
emotional support are critical throughout the entire process. By understanding
and addressing the unique needs of each stage, healthcare providers can help mothers
navigate labor with confidence and achieve the best possible outcomes for themselves
and their babies.
