Neonatal intensive care practice has its moments I
would say; several actually. Sending a micropreemie home, watching a
meconium aspiration pneumonia improve on high frequency ventilation and
nitric oxide, managing to insert a life-saving central line catheter
into a fine thread like vein, cherishing the normal neurodevelopment of
a critically ill infant; all of these and more make the effort worth it.
Why then, did the neonatologist in me decide to put myself at risk of
criticism with this manuscript which could ripple some still waters?
Albeit I am no virtuoso in the field of medical research, having faced
the maelstrom of intensive care on my feet for over 10 years, I wish to
comment on a guideline that makes a difference to every day practice.
The neonatal resuscitation protocol (NRP) for the term newborn, can be
described as "daily bread" to the genus of intensivists called
neonatologists and has undergone several modifications over the last
decades. Thyself followed, with great fervour, the ‘reforms’ made to the
protocol [1]. Over the ensuing paragraphs I intend to raise my
reservations on the tipping balance in NRP, between the quest for
evidence based practices and pragmatism.
Those who work with older children and adults know
that their patients crash mainly due to cardiac reasons. Basic life
support training hence focusses on pushing hard and fast to get the
circulation going [2]. On the other hand, babies who do not seem fine at
birth are typically so because of prior hypoxemia and all the problems
that result: hence, the focus on ‘breathing’. Either stimulate him
(forgive the literal gender bias) to cry, or drive air in by positive
pressure ventilation, and most of the other problems (bradycardia, poor
tone) sort themselves out. There is a small proportion who need chest
compressions and drugs, though [3]. Experiments on animals, and results
from various clinical studies, apparently guided changes in the protocol
and aimed at improving outcomes, which is indubitably the correct way
forward.
Did we outbid practicality in this quagmire of trying
to add more and more boxes and branches to the resuscitation algorithm?
Ab initio, everything seemed undeniably robust. Certain vital
information was essential at birth (the first ‘box’ in the algorithm),
and all it took to decide if the baby was fine was that he should cry
with gusto and look all flexed and pink within minutes. But the contents
of these so-called boxes kept changing, with its members moving in and
out with every update. Even if you manage to let that pass, some of the
additions that came in later further along the algorithm does want to
make you sit up and roll your eyes. It sounded reasonable to attach a
pulse oximeter probe for those who needed more supports; after all, we
swear by primum non-nocere and oxygen does do harm [4]. But
sticking ECG leads as time ticks on? And then staring at the monitor for
precious seconds to get readings and act: now that is a tough one to
comprehend in the chaos. Specifically when the evidence is tenuous at
best; as slippery as the baby in fact [5]. Whatever happened to years of
training listening to the lub-dub through the instrument we wield as the
mark of a doctor?
Let that go by too. What seemed completely overboard
and actually made me gape incredulously was this. Suppose the little
fellow needs chest compressions too (remember someone is already
ventilating him from the head end by then); the ‘compressor’ who was on
one side of the baby needs to move to the head end and nudge the
‘ventilator’ to swap positions. The picture that comes to mind is that
of an entangled crochet of the operators’ forearms and hands. Why not
continue the two-thumb chest compression from one side, allowing the
airway person to continue his good work from the head end (especially
considering the stability of the more important airway)? Seemingly to
make way for a third person to insert the umbilical vein canula, if
required. What happened to the other side of the baby, usually the left?
Try telling me that clinical examination and procedures need to be done
from the right side of the patient (one of the first ‘rules’ drilled
into a medical student). The foundation for this custom is quite simply
convention [6]. A right hander may do a better job while examining
asymmetric organs like the liver, spleen or heart; but the umbilical
stump? Try it on a mannequin, makes no difference at all- right or not
right!
I could go on and on. Adding to the angst is the
concern that a student/ trainee is reprimanded; or worse-still, failed
in the objective structured clinical examination stations, for not
strictly adhering to the rule-book. Not to mention the ever looming
medico-legal issues that can be pursued by those who go to court for
‘errors’ during resuscitation.
At the end of the road, all we need to do most of the
time, is to reverse the hypoxemia and hypercarbia by effectively
ventilating the lung, and the heart and brain follow suit. But no, we
like to complicate everything. I am reminded of the historical Rube
Goldberg machine!
On a more serious note, if we set aside a miniscule
fortunate fraction of the population, our country’s less privileged
interiors are still grappling with bare minimum availability of
equipment and trained personnel [7,8]. With great efforts, the neonatal
mortality has dropped from 38 to 23.5 per 1000 live births [9]. But we
have miles to go. A close look at the vast differences in statistics
within the country seems to indicate the need for very specific regional
and local microplanning. In such conditions, we need to earnestly
contemplate the practical applicability of the ever evolving NRP; and
consider local, regional logistics and readiness before blanket
recommendations are made. An additional section in the NRP guidelines on
adoption of new guidelines at various levels of healthcare may be added
to address similar issues.
