Foreword
Neurocritical care is one of the newest and most exciting specialties in
medicine today. As recently as the late 1980s, neurocritical care in the
modern sense did not exist. Neurosurgical intensive care units (ICUs)
had been established in larger teaching hospitals, but the patient’s
ticket into the unit was via the operating room. Neurosurgeons under-
stood that close clinical monitoring during the postoperative period
was essential for attaining good outcomes; it would be tragic if all of
their hard work and surgical skill would go for naught because a post-
operative complication was not picked up and managed in a timely
fashion. In those days, neurosurgeons directed the care of their pa-
tients, the units were open, and consultants were abundant. Apart from
specially trained neuro-nurses, intracranial pressure monitors, and the
novel use of a pulmonary artery catheter to apply hypertensive hyper-
volemic therapy for vasospasm, there was little to differentiate the
neurologic ICU from any medical or surgical ICU.
Things could not be more different today. Neurocritical care is now
recognized as a bona fide subspecialty of medicine. The Neurocritical
Care Society was incorporated in 2002, the journal Neurocritical Care
began publication in 2004, and the first U.S. Neurocritical Care Board
Examination was given in 2007. The past 20 years have witnessed an
explosion of therapies for conditions that were long considered un-
treatable, including reperfusion therapies for acute ischemic stroke, hy-
pothermia for cardiac arrest, and hemostatic and local thrombolytic
therapy for intracerebral hemorrhage. Proof of effectiveness varies for
these treatments, but clearly the rules have changed, and new battle
lines have been drawn. Even more exciting are the transformational in-
sights into the comatose human brain that have come from the appli-
cation of newer sophisticated neuromonitoring modalities. It is now
feasible to continuously monitor brain tissue oxygenation and blood
flow, neurochemistry, and electrical function in real time. The chal-
lenge that confronts us today is how to make optimal use of this infor-
mation in ways that can improve clinical outcomes.

viii Foreword
Perhaps nothing reflects the spirit of neurocritical care more, how-
ever, than the forward-looking attitudes that neurointensivists have
regarding prognosis. Our patients are the sickest of the sick. A devas-
tating injury to the brain—unlike any other organ—threatens a person’s
“being” like nothing else can. The diseases that we now consider to be
our greatest challenges are exactly those that were typically consid-
ered untreatable just 10 or 20 years ago. We have discarded the ther-
apeutic nihilism of older days and replaced it with hope and a
newfound respect for the resilience of the human brain. We still have
a long, long way to go, but as we continue to challenge, probe, explore,
and test new approaches to treating severe brain injury, we have every
reason to be optimistic.
Dr. Frontera’s Decision Making in Neurocritical Careis a succinct
and highly utilitarian introduction to the basics of managing patients
in the neurologic ICU. The emphasis is on rapid, focused clinical evalu-
ation and evidence-based management strategies. Medication dosages
and management protocols are spelled out in a clear and direct fash-
ion. When there is a lot of variability and controversy regarding how a
disease state or condition should best be treated, this is highlighted and
the therapeutic options are spelled out. Whether you are a nurse, med-
ical student, resident, fellow, or attending physician, it is the perfect
quick reference for managing critically ill neurologic patients.

Preface
The aim of this book is to provide a basic overview of the new and rap-
idly developing subspecialty of neurocritical care in a format that is
easily accessible. As neurocritical care develops and becomes more spe-
cialized with new diagnostic, monitoring and therapeutic modalities,
neurologists, neurosurgeons, and critical care medicine physicians will
find themselves managing patients with unique physiologic needs. In
addition, with the trend toward an increased number of beds in inten-
sive care units, more physicians will be treating more patients with a
critical illness.
This book is structured to deal with adult neurocritical care diag-
nosis, evaluation, and therapeutic decision-making as it would arise for
the typical provider. The focus on flowchart algorithms and decision
trees allows for a streamlined overview of each topic. The book con-
tains all of the important evidence-based elements essential to man-
agement in a format that is portable and allows for easy reference. Each
chapter begins with a case example and provides bulleted essentials of
diagnosis, including epidemiologic data and a differential diagnosis, ex-
amination features and suggestions for laboratory, imaging, and spe-
cial diagnostic studies. Evaluation and treatment options are discussed
and each chapter ends with “Pearls and Pitfalls” in evaluation and man-
agement.
Decision Making in Neurocritical Care will also prove to be a useful
study guide, as it covers specific topics that appear on the United
Council of Neurological Subspecialties Neurocritical Care Board
Examination.
