PUSHING IN SECOND STAGE LABOR 2
Abstract
Second stage labor management is highly modifiable and greatly influenced by nursing care.
Research of the care of laboring women is a highly controversial topic. Explanation of the
second stage labor process is broken down into phases. The fetal and maternal effects of
coached versus uncoached pushing efforts will be reviewed and evaluated through journal
evidence. Implementation of evidence-based practice by healthcare providers is essential to
ensure a positive outcome.
PUSHING IN SECOND STAGE LABOR 3
Coached Versus Spontaneous Pushing In Second Stage Labor
The birth of a baby is an exciting and emotional event in a woman’s life. “Patients give
nurses permission to enter their lives and share their most intimate life experiences” (American
Nurse Association (ANA), 2004, p. 17). Supportive care of a woman in labor allows her to be an
active participant in deliver, rather than have it managed. Guidance of nursing interventions
through use of evidence-based practice will contribute to successful management of second stage
labor. “Nursing is a dynamic profession, blending evidence-based practice with intuition, caring,
and compassion to provide quality care” (ANA, 2004, p. 17).
The obstetrical outcomes, associated with coached versus uncoached pushing during the
second stage of labor are a practice that is under study (Bloom, et al., 2006). Management of the
patient in second stage labor has been a controversial topic among the various medical
disciplines. “The second stage of labor is a profound experience for expectant mothers and a
period of intense, continuous care by a nurse or other qualified person” (Roberts, 2003, p. 794).
Care providers goals are to provide the mother and infant with the best outcomes, as well as a
pleasant birth experience. Differing opinions between medical and midwifery models of care
will guide this practice paper.
The avoidance of invasive surgical interventions, such as cesearean sections or use of
forceps, is a major goal of birth attendants who favor spontaneous births. An inter-relational
aspect of childbirth, including support and communication, is necessary to promote a
spontaneous birth. Women have given birth at home for centuries, being allowed to let their
bodies guide the process of birth. The evolution of medical technology has forced the
interruption of what is natural by providing interventions that medical personnel have deemed
necessary.
PUSHING IN SECOND STAGE LABOR 4
In the first 9 editions of Williams Obstetrics textbooks, which encompasses the first half
of the 20th century, there was no mention of coaching maternal expulsive efforts during the
second stage of labor. Coaching is not routinely indicated, and the normal reflexive urge to bear
down results from the fetal presenting part to distend the pelvic floor. By the 10th edition (1950),
Eastman stated, “In most cases, bearing-down efforts are reflex and spontaneous in the second
stage of labor, but occasionally the patient does not employ her expulsive forces to good
advantage and coaching is desirable” (Bloom, et al., 2006, p. 10). The William’s Obstetrics
textbook (Cunningham et al., 1997) advises providers to instruct women to “take a deep breath
as soon as the next uterine contraction begins, and with her breath held, to exert downward
pressure” (Sampselle, C., Miller, J., Luecha, Y., Fischer, K., & Rosten, L., 2005, p. 696).
In the role of Clinical Coordinator of the Birth Center at Covenant Healthcare in
Saginaw, Michigan, the unique opportunity to observe many deliveries by a wide variety of
nurses, midwives, residents, and attending physicians. It is totally amazing despite the research
done for evidence-based practice how many healthcare providers are resistant to change. The
Clinical Nurse Specialist in the department is very thorough in her investigation into the most
current research and practices. There are extensive educational offerings to familiarize all
aspects of the healthcare team as to the current recommended practice. Eventually the practices
are adopted, but with great resistance by members of the healthcare team.
Phases of Second Stage Labor
The traditional definition of second stage is the time from the diagnosis or detection of
complete cervical dilatation to the birth and is seen as the explosive phase, that is, the
portion of labor when the woman experiences an urge to bear down and to push.
However, an involuntary urge to push may precede the complete dilatation of the cervix
PUSHING IN SECOND STAGE LABOR 5
or may occur sometime after the recognition of complete cervical dilatation. This
variation in the time of the initial urge to push is due to other obstetric factors that must
be favorable for further fetal descent and birth. (Roberts, 2003, p.795)
The physical and behavioral characteristics of second stage need to be understood to
appropriately provide the interventions necessary. “Second stage care practices can have an
adverse impact on fetal oxygenation, pelvic floor dysfunction, urinary or fecal incontinence, and
sexual dysfunction, as well as cesearean birth rates” (Roberts & Hanson, 2007, p. 238). The
possible adverse effect of coached versus spontaneous pushing efforts will be examined.
Directing a woman in second stage labor to push when it is determined that the cervix is fully
dilated has been traditionally performed. There are several “rules” that have been followed
which may cause adverse clinical complications. “One rule is “not to push prior to complete
cervical dilation;” another is “to push when the cervix is complete” (Roberts, 2002, p. 3).
“Despite evidence that raises concerns about directed pushing, more than 75% of 3,000 labor and
delivery nursing staff members encourage prolonged Valsalva-type pushing during the second
stage of labor” (Sampselle, et al., 2005, p. 696).
Providers insist that involuntary urges to push be suppressed and label pushing as not
appropriate until a designated authority certifies full dilation of the cervix, while
apologetic women valiantly strive to hold back their body’s urge to push. Similarly,
provider direction of the process of pushing during the expulsive phase of labor discounts
the birthing woman’s innate rhythmic imperative pushing. (Sampselle, et al., 2005, p.
696)
PUSHING IN SECOND STAGE LABOR 6
Pelvic Phase
The pelvic phase is the first phase of second stage of labor. The fetal head is negotiating
the pelvis, rotation and descent occurs. By lengthening this phase, the active pushing is
shortened by ensuring the obstetrical conditions are truly optimal, which will decrease the
amount of perineal muscle and nerve damage that may occur with a lengthy pushing phase. This
is accomplished by not encouraging the patient to push until she has a strong urge to do so. This
represents that the head rotation and descent is well advanced (Roberts, 2003, p. 796).
Perineal Phase
In the perineal phase, the fetal head is lower in the pelvis and is distending the perineum.
The perineal phase may be marked with a significant decrease in fetal pH, strong maternal
bearing down efforts (BDE) and breath holding (Roberts, 2003, p. 796).
Pressperiode Phase
The pressperiode phase is the final stage, or active pushing phase of second stage labor.
Reinforcement of effective BDEs, instruction on effective pushing focus, or assistance in finding
a more efficient pushing position may be necessary in some women. “Directions should be
reserved for those who need assistance. For many women, only positive reinforcement,
encouragement, and comfort measures are needed to achieve progress and a timely birth”
(Roberts, 2003, p. 796).
Coached Versus Uncoached Pushing
Coached Pushing
“Care provider directions to laboring women to bear down with each contraction
immediately upon complete dilatation of the cervix continue to be common during the
management of second stage labor” (Roberts & Hanson, 2007, p. 238). The closed glottis and
PUSHING IN SECOND STAGE LABOR 7
strenuous bearing down associated with the Valsalva maneuver, brings about physiologic
changes that impact both the mother and baby during second stage of labor. The ritual mantra of
“push, Push, PUSH,” that is mostly used by the provider intending to be supportive, is
interpreted as that of drill sergeant or a demanding parent (Sampselle, et al., 2005)
Maternal adverse effects. There is an increase in thoracic cavity pressure causing a
decrease in venous return and a resulting decrease in oxygenated blood to perfuse the uterus,
placenta, and fetus (Roberts, 2002, p. 4). Use of sustained Valsalva bearing down efforts results
in maternal fatigue, more perineal tears, decreased urogynecologic function, including decreased
bladder capacity and an increase in stress incontinence postpartum (Roberts & Hanson, 2007, p.
238). Roberts, (2002, p. 4), states that in a comparative study by Beynon,
The reported need for forceps assistance and the incidence of perineal trauma (episiotomy
or laceration) were greater for women who were directed to push upon complete
dilatation than for 100 women for whom directions were delayed until they had an
involuntary urge to bear down (p.4).
Fetal adverse effects. The use of Valsalva maneuver has been reported to result in fetal
acidemia and de-oxygenation. There is the possibility of the fetal head not being situated in the
pelvis that is conducive to descent and progression may not occur. In the active maternal bearing
down phase, a study showed that the fetal acid base status did not change in the first phase, but
the higher levels of lactic acid and pCO2 and lower pH did occur in the final part of second
stage. “The fetus is more adversely affected by a longer phase of forceful pushing than by the
period of time between complete dilatation and active pushing” (Roberts, 2002, p. 6).
PUSHING IN SECOND STAGE LABOR 8
Spontaneous Non-Coached Pushing
Spontaneous pushing allows the woman in labor to listen to her own body cues. A non-
coached, non-directed, self-paced pushing pattern, with multiple short pushes and no sustained
breath holding is encouraged and observed by these women (Albers, 2007).
When women push spontaneously, they begin to push from their resting respiratory
volume, and they push multiple times per contraction (3-5) for 3-5 seconds per effort,
followed by about 2 seconds of breaths and the release of air. There is synchrony
between the woman’s respiratory and uterine function that may allow spontaneous
bearing-down efforts to take advantage of the force generated by abdominal muscle
action (Hanson, 2009, p. 32).
A woman’s involuntary urge to bear down is evoked when a contraction pushes the fetal
head stretching the muscles of the pelvic floor and evokes Ferguson’s reflex, which happens with
a release of oxytocin. The release of oxytocin augments to quality of uterine contractions and
the expulsive efforts of the mother are initiated (Roberts, 2003, p. 797). Providers that support
spontaneous pushing provide feedback about how the woman is doing and encouraging her in the
birth (Sampselle, et al., 2005).
There was a strong positive association between the percentage of provider
communication phrases categorized as supportive of spontaneous pushing and the
percentage of maternal pushing behavior that was, in fact, spontaneous (Pearson’s r
= .80, p ≤ .001, n = 20). Likewise, there was a strong positive association between the
percentage of provider communication phrases categorized as directed and the percentage
of maternal pushing behavior that was directed (Pearson’s r = .89, p ≤ .001, n = 20).
(Sampselle, et al., 2005)
PUSHING IN SECOND STAGE LABOR 9
Maternal advantages of spontaneous uncoached pushing when this “urge” occurs are a
feeling of autonomy, an increase in self-esteem, and a positive perception of their birth
experience. The positive communication provided by healthcare providers in the birth
experience also facilitates a woman’s sense of accomplishment and can increase the mother
infant bonding. In the birth center, patients with an epidural are allowed and encouraged to labor
down (delay pushing) until the urge to push is felt. This is the practice of the majority of our
providers, with the exception being if the provider is nearing the end of their call and want to be
present for the delivery. It is very difficult sometimes to get the providers to think about what is
best for the patients, even some of the nurses observed have avoided checking a patient’s station
to not have a change of shift delivery. The focus should be what is best for the patient, not what
is best for the healthcare provider.
Barriers to the facilitation of spontaneous uncoached pushing efforts usually are the result
of lack of knowledge of healthcare providers. Most providers urge the prolonged bearing down
efforts in the belief of “the way we have always done it” or an impatience with the time involved
at the bedside. The experiences of the patient, family members, and healthcare providers can
strongly influence the behaviors in second stage labor management. The media has always
portrayed the “bear down and push” visual of the delivery process. A lack of knowledge may
contribute to this image being the only way the patient may know how to push without proper
guidance from her healthcare team.
Due to the intensive fetal heart monitoring systems, the length of the second stage is not
the only criteria to decide of interventions or operative termination of labor is necessary.
The guidelines recommend operative delivery be “considered” when 3 hours have
elapsed for a nullipara with regional anesthetic or 2 hours for one without, and when 2
PUSHING IN SECOND STAGE LABOR 10
hours have elapsed for a parous parturient with a regional anesthetic or 1 hour without.
An analysis of 4,745 births from the hospital records of nine midwifery services by
Albers et al. has identified the limits of labor (mean plus 2 standard deviations that
represents 95% of a population) in a population of U.S. women of mixed ethnicity…
Investigators have emphasized the importance of continued progress in fetal descent and
reassuring fetal heart tones to justify second stages that exceed the statistical “norms” for
that population. (Roberts, 2002, p. 5)
Studies for improved perineal floor outcomes have shown that women who had used the
Valsalva pushing had less favorable urodynamic indices, indicating pelvic floor dysfunction
from the forceful pushing effort (Albers, 2004).
Observations of the laboring patients of the Birth Center have shown the decreased time
of active directed pushing before the head has descended to a favorable station causes much less
swelling of the perineal tissue and subsequent trauma to the tissue. The providers who use their
fingers to help the patient “find the right spot” for pushing when they are not feeling the urge has
also been observed to result in increased perineal trauma. One of the Birth Center physicians,
along with many of the midwives, use the practice of warm compresses to the perineum when
the fetal head starts to cause visible bulging pressure. This practice has shown in our department
to decrease the incidence of perineal trauma. Most of the Birth Center physicians are not
supportive of this decrease in directed pushing with manual manipulation of the perineum. The
nurse’s whom support this practice will spend much time at the bedside facilitating the optimal
outcome and involving the physician only as necessary to avoid unnecessary interventions.
The nurses, midwives and other female healthcare providers are more accepting of the
natural process of the birth. There are some of our male physicians, who will support this
PUSHING IN SECOND STAGE LABOR 11
process, as well as, some female physicians who do not. This is most evident in those who
support Jean Watson’s Theory of Human Caring philosophy. The Theory of Human Caring
encompasses the “special kind of relationship involving a high regard for the whole person and
his or her being-in-the-world” (Kearney-Nunnery, 2008). Development of an inter-relationship
between care provider and patient enables the communication necessary to accomplish a
common goal. The process of birth, even though not an illness, involves the clinical caritas
process is applicable in bringing the patient and healthcare provider together to reach a common
goal. Applying this theory to practice is very essential in the makeup of a good obstetrical nurse.
At a time in a woman’s life when she is very vulnerable, a nurse is able to assist the woman to
maintain dignity, autonomy, and self-esteem.
Conclusion
The benefits to both the mother and newborn with spontaneous uncoached pushing
efforts are apparent through the evidence in this paper. Mothers have fewer incidences of
operative delivery, perineal trauma, and bladder trauma when allowed to push spontaneously.
Newborns suffer less acidemia and de-oxygenation when a mother can push uncoached. “Even
in the face of clinical challenges, evidence-based nursing care can help achieve the improved
outcomes that have been documented from a women’s spontaneous bearing-down efforts during
the second stage” (Hanson, 2009). Due to the limitations of many studies, further research needs
to be conducted involving variables such as; primiparous and multiparous women, and women
with or without epidurals, and larger sample populations (Simpson & James, 2005).
Recommendations for studies comparing cord blood gases collected at the time of delivery.
Nurses must strive to make goais to promote evidence-based practices with even the most
resistant of healthcare
