Advances in science and medicine have the potential to bring great progress to society
but not without raising new ethical questions along the way. Progress in the technology of
neonatal resuscitation and intensive care has been no exception. Over the past several decades,
saving infants of lower and lower gestational ages has been made possible as the medically
accepted limit of viability has been pushed back (Bhatia, 2006; Donohue, Boss, Shepard,
Graham, & Allen, 2009; Doroshow et al., 2000; Kuschel & Kent, 2011; Krug, 2006; Seaton,
King, Manktelow, Draper, & Field, 2013; Singh et al., 2007; Stephens, Tucker & Vohr, 2010;
Sudia-Robinson, 2011). Technology can only go so far, and this has created a “gray zone” when
defining a truly viable infant. When an infant is born into this category, decisions must be made
about the best course of action. There is no sharp limit that can distinguish a late term
miscarriage from a viable preterm infant (Zayek et al., 2011). A libertarian ethical approach to
this issue would need to consider the extent of the personal rights of those involved in making
these decisions: the physician, the parents, and the infant. By applying the concepts of selfliberty and noninterference of rights, an ethical solution can be proposed to resolve the issue of
whether or not an infant at the edge of viability should be resuscitated or allowed to die and who
gets to make this decision.
Viability can be defined in basic terms as “the ability to work, function, or develop
adequately” (Zayek et al., 2011, p. 130). Current medical professionals expand on this definition
to explain that the limit of viability is the fetal age associated with a 50% chance of long-term
survival outside of the womb (Zayek et al., 2011). The boundaries of this limit are not clear, and
a “gray zone” exists within which a drastic differing of opinions and projected prognoses occurs.
This gray zone of viability is generally described between 23 and 24 weeks gestation or 400-500

grams birth weight (Bhatia, 2006; Kuschel & Kent, 2011; Ramsay & Santella, 2011; Seaton et
al., 2013; Sexson, Cruze, Escobedo, & Brann, 2011; Singh et al., 2007; Stephens et al., 2010;
Sudia-Robinson, 2011; Zayek et al., 2011).
Resuscitation of an infant born at the edge of viability can be a massive moral dilemma
for the parties involved. There is no governmental mandate that states an infant must be
resuscitated in all situations (Sexson et al., 2011). Neonatal Resuscitation Program (NRP)
guidelines state that it is acceptable to withhold resuscitation in some cases on the grounds of
futility (Sexson et al., 2011). This statement is vague in practice as futility cannot be certain in
many cases. The absence of true guidelines means that it is up to those involved in each specific
situation to determine whether resuscitation will take place. Unfortunately this decision is
usually made in a time of crisis where little thought has been placed on the issue up to the point
of extremely preterm labor. The main parties involved in the situation usually include the
physician, the parents of the infant, and the infant itself. All three represent different viewpoints
and are governed by their own rights and moral frameworks.
The principle of beneficence in medical practice implies that a physician should act out of
the best interest of his or her patient (Doroshow et al., 2000). Beneficence is typically the driving
force behind resuscitation due to the fact that best interest and remaining alive are often thought
of as interchangeable. A physician may also fear that if they do not resuscitate but the infant does
not die, he or she has potentially been exposed to a prolonged period of hypoxia (Krug, 2006).
This idea of nonmaleficence or “to do no harm” combined with beneficence compels most
physicians to believe that it is their job to resuscitate an infant born in the gray zone of viability
(Doroshow et al., 2000; Krug, 2006; Sudia-Robinson, 2011). However, this sense of duty felt by
physicians does not always consider the rights of the parents and of the infant. In fact, Singh et
NEONATAL RESUSCITATION IN THE GRAY ZONE OF VIABILITY

al. (2007) found that only one third of neonatologists stated that the parents’ wishes would
influence their choice whether or not to resuscitate. This discrepancy has led to various lawsuits
such as Miller v. HCA where a hospital policy to resuscitate was initiated despite the parents’
clear wishes against resuscitation and refusal to sign a resuscitation consent form. The Miller’s
baby girl was resuscitated and lived, but with profound physical and mental handicaps (Hurst,
2005; Krug, 2006). Libertarians would disagree with government involvement in this issue
claiming that government mandates infringe upon the rights of the parents to choose what is best
for their child.
Physicians may argue that parents are not able to determine what is best for the infant as
their judgment is likely clouded by anger, guilt, grief and other negative emotions (Catlin, 2005;
Doroshow et al., 2000). Most physicians claim to base the decision to resuscitate and estimation
of prognosis on the appearance of the infant at birth despite these methods proving to be largely
unreliable (Bhatia, 2006; Kuschel & Kent, 2011; Singh et al., 2007). Bhatia (2006) states that the
evaluation of the infant in the delivery room is “speculation at best” (p.525). In reality, the right
of the parents to make an informed decision could be protected if physicians would provide prenatal education on the limits of viability, prognoses of extremely premature infants, and
treatment options in these situations. There is no mention of including viability education to
parents in prenatal education guidelines (Catlin, 2005; MacDonald, 2002; Sudia-Robinson,
2011). If parents were educated on this matter, they could begin to think about what their
decision would be if faced with the situation of an infant born between 23-24 weeks. Ideally,
they could make decisions in advance and some ethicists have suggested forming some sort of
advance directive for neonates (Doroshow et al., 2000; Kuschel & Kent, 2011; Sudia-Robinson,
2011). The libertarian perspective would encourage viability education for parents so that they
NEONATAL RESUSCITATION IN THE GRAY ZONE OF VIABILITY

are better equipped to use their right to make decisions for their own child. The physician’s role
is to educate parents and perhaps guide them in making choices for the infant based on clinical
expertise and experience. In the end though, it is not the right of the physician to make decisions
for someone else’s family.
Parents can be assumed to have the best interest of their child in mind, and in the absence
of the baby’s ability to make decisions, parents are the natural surrogates (Doroshow et al., 2000;
Singh et al., 2007). Parents have a right to be adequately informed to give or refuse consent to
treatment when the outcome is questionable. This is again where prenatal education comes in to
play. Unfortunately, the only mention of preterm birth that many parents receive is through
media. This can cause parents to have a skewed perception of reality because the only stories that
make it in to the news are the stories of “little miracles” and survival against all odds (Catlin,
2005; Kuschel & Kent, 2011). Parents need to know the actual statistics of survival and survival
without impairment when considering options for their child. Catlin (2005) discusses the
American College of Obstetrics and Gynecology’s view that “presents women’s autonomy as the
overriding principle of decision making” (p. 172). Catlin further describes other feminist ethical
views on neonatal resuscitation, and libertarians would likely agree with these interpretations.
Catlin quotes a conclusion drawn after a review of ethical principles stating that “despite
beneficence owed to the fetus, the principle of maternal autonomy must be upheld and that a
woman’s wishes about fetal or newborn treatment must be respected” (p. 172). Parents have
many factors to consider when deciding on treatment for their newborn such as the financial
burden of neonatal intensive care, the possibility of lifetime care, as well as the stress and
emotional cost to their family. It is not the place of the physician, hospital policy, or government
mandates to make such important decisions for the family of these extremely premature infants.

When considering the issue of whether or not to resuscitate an infant born at the edge of
viability, the libertarian ethicist would not forget to consider the rights of the infant as well. The
Born Alive Infants Protection Act of 2002 states that any infant born breathing, with a beating
heart, pulsation of the umbilical cord or movement of voluntary muscles is a person entitled to
protection of the law (Hurst, 2005). This act does not cover infants who are born not breathing or
without a beating heart though, and the NRP guidelines have not been altered as a result of this
act. Instead, it is suggested that the infants who are not resuscitated be treated with comfort care
measures (Hurst, 2005). Infants who receive treatment in neonatal intensive care units (NICUs)
are often subjected to pain and suffering (Doroshow et al., 2000; Krug, 2006; Singh et al., 2007).
Oftentimes, resuscitation and intensive care of an infant of questionable viability is not saving
the infant’s life but instead prolonging death and extending periods of suffering (Bhatia, 2006;
Donohue et al., 2009; Sudia-Robinson, 2011). A busy NICU does not seem the ideal place to die.
When choosing comfort care over resuscitation, an infant is allowed to die warm and
comfortable in his or her mother’s arms. Just because the choice has been made not to resuscitate
does not mean that there is not any care provided for the infant. “Care” is not discontinued, only
technical interventions and advanced life support. The dying infant should still be treated with
compassion, dignity, and have their needs met (MacDonald, 2002; Sexson et al., 2011).
Quality of life is another issue that needs to be addressed when assessing whether or not
to resuscitate an infant (Bhatia, 2006; Doroshow et al., 2000; Kuschel & Kent, 2011;
Stephens et al., 2010). The majority of infants who are born between 23 and 24 weeks and
survive are faced with severe disabilities and diseases including chronic lung disease, central
nervous system damage, retinopathy/blindness, and other special health care needs (Stephens et
al., 2010). Many of these children will require a lifetime of care, and it is the family who must
NEONATAL RESUSCITATION IN THE GRAY ZONE OF VIABILITY

deal with paying for and/or performing this care. In many cases the child will need a surrogate
for their entire life, so parents as natural surrogates should not be denied decision making
privileges in the beginning of life. Libertarians would recognize the right of an infant to receive
comfort care and be free from pain and suffering, but ultimately the rights of the parents would
prevail as the main authority in decision making.
By considering the extent of rights allotted to all of the parties involved, a libertarian
solution can be proposed to resolve the issue of determining resuscitation measures of an infant
born on the border of viability. This solution to the problem would vary by case; as each case
would present with different individuals of varying circumstances being treated by different
physicians. That being said, it is not the place of the government to impose paternalistic laws and
guidelines to make these decisions and take away the right of the parents to choose what is best
for their child and for their family. While some may argue that is not moral to choose anything
but whatever means necessary to give an infant a chance at life, it is not the place of the
government to impose moral legislation. Infants have the right to be free from undue suffering
and to have someone who loves them and cares about their family as a unit make the best
decision for them. Donohue et al (2009) suggests a “gold standard” for decision making in these
cases that is “a collaborative one that balances physician, parent, and fetal/infant concerns”
(p.906). The physician’s role is to inform the parents of facts that may influence their decision
including survivability statistics, possibility of co-morbidities, and personal experiences relating
to outcomes in the specific area of practice. Ideally, this information will be presented to parents
prenatally so that they may begin to think about the issue and their beliefs before a time of crisis.
The parents should discuss their thoughts with the physician so that everyone is clear in advance
on the course of action. Of course the circumstance will be assessed at the time of birth as well.

Both the parents and physician should remember the rights of the infant as a person to be free
from unwarranted pain and suffering and to be treated with dignity and compassion regardless of
the chosen course of action. When the parents are educated and have had time to consider their
feelings towards resuscitation in advance, they will be prepared to give or refuse informed
consent. It is the right of the parents to choose what is best for their infant and for their family,
and healthcare staff as well as the law need to dutifully respect that right.
