Electrical and crush injuries share many similarities. In
both iitjuries, there is massive destruction of large muscle
groups with resultant release of both potassium and myoglobin
(see the Musculoskeletal Trauma chapter). The release of mus-
cle potassium causes a significant increase in the serum level,
which can result in cardiac dysrhythmias. Elevated potassium
levels can make administration of the depolarizing muscle
relaxant succinylcholine prohibitively dangerous.18 If chemical
paralysis of the patient is required, such as for rapid sequence
intubation, nondepolarizing agents such as vecuronium or
rocuronium may be used. Myoglobin is a molecule found in
the muscle that assists the muscle tissue in transportation of
oxygen. When released into the bloodstream in considerable
amounts, the myoglobin is toxic to the kidneys and can cause
kidney failure. This condition, myoglobinuria, is evidenced by
tea- or cola-colored urine (Figure 15-21).

Prehospital care providers are commonly called upon to pro-
vide interhospital transfers of patients after electrical iitjuries.

the resultant serum levels. Symptoms can range from mild head-

tration as it is a more efficient delivery modality and avoids
exposure of healthcare providers to amyl nitrate fumes. The
nitrate medications change some of the patient's hemoglobin
into a form called methemoglobin, which attracts the cya-
nide away from the site of toxic action in the mitochondria
of the cell. Once the cyanide binds with the methemoglobin,
the mitochondria can once again begin to produce energy for
the cell. Unfortunately, methemoglobin is toxic because it does
not carry oxygen to cells as well as hemoglobin does. This
decrease in oxygen delivery can exacerbate the tissue hypoxia
associated with increased carbon monoxide levels that the
victim may also have as a result of smoke inhalation.26•27

The third medication in the kit is sodium thiosulfate, which
is given IV after the nitrate. The thiosulfate and cyanide from the
methemoglobin are metabolized to thiocyanate, which is safely
excreted in the patient's urine.

Because of the toxicity of methemoglobin and the time
needed to administer the full Lilly kit, hydroxocobalamin has
become the preferred antidote for the treatment of cyanide
poisoning.

such as ammonia, hydrogen chloride, and sulfur dioxide form
corrosive acids and alkalis when they are inhaled and react
with water.32 These poisons cause necrosis of the cells lining
the trachea and bronchioles. Normally, these cells have tiny
hairlike structures called cilia. On these cilia is a blanket of
mucus that captures and transports normally inhaled debris
to the oropharynx, where the debris is swallowed into the GI
tract. Several days after an inhalation injury, these cells die.
The debris from these necrotic cells and the debris these cells
typically capture accumulate instead of being removed. The
result is an increase in secretions, plugging of the airways with
mucus and cellular debris, and an increased rate of life-threat-
ening pneumonia.

Prehospital Management

The initial and most important element of caring for a patient
with smoke exposure is determining the need for orotra-
cheal intubation. Continuous re-evaluation of airway patency
is required in order to recognize developing signs of airway
obstruction. Change in the character of the voice, difficulty han-
dling secretions, or drooling are signs ofimpending airway occlu-
sion. Whenever patency of the patient's airway is in doubt, the
prehospital care provider can proceed with securing the airway
using orotracheal intubation.33.:w In some cases, rapid sequence
intubation may be necessary, if allowed, to manage the airway.
In the event of long transport times, rendezvous with an agency
capable of providing definitive airway management should be
considered.

Patients with smoke inhalation should be transported to
bum centers even in the absence of surface burns. Bum centers
treat a greater volume of patients with smoke inhalation and
offer unique modes of mechanical ventilation.

Contact Burns

Contact burns are the second most common mechanism of burn
injury in children, whether accidental or intentional. All body
smfaces have some degree of curvature. When an accidental
contact burn occurs, the burning agent makes contact with the
curved body smface area. The burning instrument is deflected
off the curved smface, or the victim withdraws from the hot
object. The resultant injury has an irregular burn edge and depth.
When a child receives an intentional contact burn, the inflicting
implement is pressed onto the child's skin. The resultant injury
has sharp lines of demarcation between burned and unburned
tissue and uniform depth.39 Common objects involved in contact
burns include curling irons, steam irons, radiators, and hot pots
and pans.

The absorption capacity of the radiation is more damaging
than the actual dose of radiation. Equivalent doses of different
forms of radiation will have dramatically different effects on
an individual.

The typical exposure to radiation occurs in the setting ofan
industrial or occupational incident. However, with the increasing
threat of global terrorism, the detonation of a "dirty bomb" or
radiation dispersal device (conventional explosive with radioac-
tive material added) or a small, improvised nuclear device (i.e.,
"dirty nuke") is a possibility. (See the Explosions and Weapons of
Mass Destruction chapter for more detail.)

The detonation of a dirty bomb is designed to spread radio-
active material over a large area. While the explosion itselfwould
likely injure or kill individuals in close proximity to the blast, the
risk from the radioactive material is, in reality, relatively small.
There is little likelihood ofabsorbing a large enough dose ofradi-
ation to produce clinical illness.

The detonation of a nuclear weapon in a metropolitan area,
on the other hand, would injure and kill many people by three
mechanisms: thermal burns from the initial firestorm, super-
sonic destructive blast causing blunt and penetrating trauma,
and production of radiation. Mortality from a combination of
thermal and radiation burns is greater than that from either ther-
mal or radiation burns alone of equal magnitude. The combina-
tion of thermal and radiation burns has a synergistic effect on
mortality.41

Chemical agents are classified as acid, base, organic, or inor-
ganic. Acids are chemicals with a pH between 7 (neutral) and 0
(strong acid). Bases are agents with a pH between 7 and 14 (strong
base) (Figure 15-29). Acids damage tissue by a process called
coagulative necrosis; the damaged tissue coagulates and trans-
forms into a barrierthatprevents deeperpenetration ofthe acid. In
contrast, alkali bums destroy the tissue by liquefaction necrosis;
the base liquefies the tissue, allowing the chemical to penetrate
more deeply and cause increasingly deeper tissue damage.

any remaining reagent The key to lavage is to use large amounts of
the water. A common error is to rinse 1 or 2 liters of water across
the patient, then stop the lavage process once the water starts to
pool and accumulate on the floor. When lavaged with only small
amounts offluid, the offending agent is spread across the patient's
body surface area and not flushed away.44,45

fluid may cause ir\jury to previously unexposed and unir\jured
areas of the patient's body as the contaminated lavage accumu-
lates beneath the patient. One simple way ofpromoting runoff in
a prehospital setting is to place the patient on a backboard and
then tilt it with cribbing or other means to elevate the head. At
the lower end of the board, tuck a large plastic garbage bag to
capture the contaminated runoff.

Neutralizing agents for chemical burns are typically avoided.
Often in the neutralizing process the neutralizing agents give
off heat in an exothermic reaction. Therefore, a well-meaning
prehospital care provider may create a thermal bum in addition
to the chemical bum. Most commercially available decontami-
nation solutions are made for the purpose of decontaminating
equipment, not people.

• Burn injuries are not isolated to the skin; these are systemic injuries of unparalleled magnitude. Patients

with major burn injury will experience dysfunction of the cardiovascular, pulmonary, gastrointestinal, renal,
and immune systems.
• Failure to provide appropriate fluid resuscitation will lead to refractory shock, multiorgan dysfunction, and
even deepening of the burns. The role of the prehospital care provider is, therefore, crucial in optimizing
survival after a burn injury.
• Although complicated and dangerous, burns are rarely rapidly fatal. A patient with severe smoke inhalation
and large thermal burns may take several hours or days to die. Patients with burns also are likely to have
other mechanical trauma.
• Dramatic burns may focus the prehospital care provider's attention away from other, potentially life-
threatening injuries. Performing primary and secondary assessments will reduce the likelihood of missing
these injuries (e.g., pneumothorax, pericardia! tamponade, splenic rupture).
• Constant vigilance is required to avoid becoming a victim. Often the injuring agent still poses a risk for
injuring the prehospital care providers.
• Even small burns in areas of high function (hands, face, joints, perineum) may result in long-term impair-
ment from scar formation.
• Familiarity with burn center transport criteria will help ensure that all patients can achieve maximal func-
tion recovery after burn injury.
• The leading cause of death in patients with burns is complications from smoke inhalation: asphyxiation,
thermal injury, and delayed toxic-induced lung injury. Frequently, patients do not develop symptoms of
respiratory failure for 48 hours or longer. Even without burns to the skin, victims ofsmoke inhalation should
be transported to burn centers.
• Victims of burn injury from hazardous materials, such as chemicals or radioactive agents, should undergo
decontamination to avoid inadvertent spread of the material to prehospital and health care providers.

You are called to a residential structure fire. When your unit arrives, you witness a two-story house that is fully involved with fire and
thick, black smoke pouring out of the roof and windows. You are directed to a victim who is being cared for by EMRs. They tell you
that the patient re-entered the burning building in an attempt to rescue his dog, and he was carried out unconscious by fi re fighters.

Your patient is a man who appears to be in his thirties. The majority of his clothes have been burned off. He has obvious burns to
his face, and his hair has been singed. He is unconscious; he is breathing spontaneously, but with snoring respirations. The EMRs have
placed the patient on high-flow oxygen with a nonrebreather mask. On physical examination, his airway is patent with manual assistance
Gaw thrust); he ventilates easily. The sleeves of his shirt have been burned off. His arms have circumferential burns, but his radial pulse is
easily palpable. His heart rate is 118 beats/minute, blood pressure is 148/94 mm Hg, ventilatory rate is 22 breaths/minute, and oxygen
saturation (Spo2), taken by pulse oximeter, is 92%. On physical examination, you determine that the patient is burned on his entire head
and has blistering of the anterior chest and abdomen, along with full-thickness burns of his entire right and left arm and hand.

• What is the extent of burns for this patient?
• What are the initial steps for managing this patient?
• How does the prehospital care provider recognize an inhalation injury?

CHAPTER 15 Burn Injuries 427

The patient has sustained critical injuries. Given that the patient was found collapsed in a burned building with burns to the face and
labored respirations, you must be concerned that the patient has inhaled a large amount of smoke.

Evaluate and re-evaluate for airway edema and an inhalation injury. Airway patency needs to be a concern; however, the patient
currently is managing his own airway. Keeping in mind that often the best person to manage an airway is the patient, you need to
balance the time required to transport the patient with the difficulties of airway management in a patient with an edematous airway.
If transport will be prolonged or delayed, secure the airway by tracheal intubation. The patient clearly needs 100% oxygen given the
exposure to smoke and concerns about asphyxiants. If you elect to intubate this patient, be careful to secure the ET tube. Anchor t he
tube securely. A portable carbon monoxide monitor placed on the patient reports a carboxyhemoglobin level of 16%, which is already
being treated since the patient is on 100% oxygen. You consult the local protocol regarding management of smoke inhalation with
potential cyanide poisoning.

Both upper extremities have deep, full-thickness burns. You are not able to identify any veins to establish an IV line. Neither leg is
burned, nor is there evidence of any fractures. An 10 line is started in the left tibia, and an infusion of lactated Ringer's is begun.

The patient is burned on the entire head, both upper extremities, and the anterior trunk. Each limb is approximately 9% of TBSA,
the anterior trunk is 18%, and the head is approximately 9%. Therefore, the estimated TBSA burned is approximately 45%. The patient
weighs approximately 175 pounds, or 80 kg. Estimate the patient's fluid needs using the Parkland formula, as follows:

45% TBSA burned x 80 kg x 4 ml/kg/TBSA burned = 14,400 ml to be administered in first 24 hours

Half this fluid total is administered in the first 8 hours after injury. Therefore, the hourly rate for the first 8 hours is:

14,400 ml/2 = 7,200 ml to be administered in first 8 hours

Calculate the hourly fluid rate:

7,200 ml/8 = 900 ml per hour for hours 0 to 8

You are called to t he scene of a motor vehicle crash on a heavily traveled highway. Two vehicles have been involved in a fronta l offset
collision. One of the vehicle's occupants is a child improperly restrained in a child booster seat. No weather-related factors are involved
on this spring afternoon.

On arrival at the scene, you see that the police have secured and blocked traffic from the area around the crash. As your partner
and the other arriving crew are assessing the other patients, you approach the child. You see a young boy, approximately 2 years of age,
sitting in the booster seat, which is slightly turned at an angle; there is blood on the back of the headrest of the seat in front of him.
Despite numerous abrasions and minor bleeding from the head, face, and neck, the child appears very calm.

Your primary and secondary assessments reveal a 2-year-old boy who weakly repeats "ma-ma, ma-ma." His pulse rate is 180 beats/
minute, with the radial pulses weaker than the carotid; his blood pressure is 50 millimeters of mercury (mm Hg) by palpation. His ven-
tilatory rate is 18 breaths/minute, slightly irregular, but w ithout abnormal sounds. As you continue to assess him, you note that he has
stopped saying "ma-ma" and seems to just stare into space. You also not e t hat his pupils are slightly dilated, and his skin is pale and
sweaty. A woman who identifies herself as the family's nanny tells you that the mother is en route and that you should wait for her.

support extremely challenging and technically difficult. Effective
pediatric trauma resuscitation mandates the availability ofappro-
priately sized airways, laryngoscope blades, endotracheal (ET)
tubes, nasogastric tubes, blood pressure cuffs, oxygen masks,
bag-mask devices, and associated equipment. Attempting to
place an overly large intravenous (IV) catheter or an inappropri-
ately sized airway can do more harm than good, not only because
of the potential physical damage to the patient, but also because
it may delay transport to the appropriate facility. Color-coded,
length-based resuscitation guides (discussed later in the chapter)
provide practical medication and equipment references.17

the sniffing position (Figure 16-5). In the presence of trauma,
however, the neutral position best protects the cervical spine
by keeping it immobilized to prevent the fl.exion at the fifth
and sixth cervical vertebrae (C5 to C6) and the extension at Cl
to C2 that occurs with the sniffing position. In this position, a
jaw-thrust maneuver can be used to facilitate airway opening
if needed.

Manual stabilization of the cervical spine is done during air-
way management and maintained until the child is immobilized
with an appropriate cervical immobilization device, whether it is
commercially purchased or a simple solution such as towel rolls.
Additionally, placing a pad or blanket of 2 to 3 centimeters (cm;
about 1 inch) in thickness under an infant's torso can lessen the
acute fl.exion of the neck and help keep the airway patent.

Bag-mask ventilation with high-fl.ow (at least 15 liters
per minute) 100% oxygen probably represents the best choice
when the injured child requires assisted ventilation.11 If the
child is unconscious, an oropharyngeal airway may be consid-
ered, but due t o risk of vomiting, it should not be used in the
child with an intact gag reflex. This is also true of the laryngeal
mask and King LT airways, both of which are supraglottic air-
ways; when sized appropriately, these devices can be consid-
ered for airway management in pediatric trauma patients who
cannot be ventilated by simple bag-mask device. In very young
children, especially those weighing less than 20 kg, these
devices can cause iatrogenic upper airway obstruction by
causing the relatively larger pediatric epiglottis to fold into the

CHAPTER 16 Pediatric Trauma 4 5 3

• The primary assessment and management of the pediatric patient in the prehospital setting require applica-
tion ofstandard trauma life support principles modified to account for the unique characteristics ofpediatric
patients.

• Traumatic brain injury is the leading cause of death from trauma, as well as the most common injury for
which pediatric patients require airway management.

• Children have the ability to compensate for volume loss longer than adults, but when they decompensate,
they deteriorate suddenly and severely.

• Significant underlying organ and vascular injury can occur with few or no obvious signs of external injury.
• Pediatric patients with the following signs are unstable and should be transported without delay to an appro-

priate facility, ideally a pediatric trauma center:
• Respiratory compromise
• Signs of shock or circulatory instability
• Any period of postinjury unconsciousness
• Significant blunt trauma to the head, thorax, or abdomen
• Fractured ribs
• Pelvic fracture
• Always consider the possibility of abuse or nonaccidental trauma when the history of the injury does not
match the presentation of the patient.

You are called to the scene of a motor vehicle crash on a heavily traveled highway. Two vehicles have been involved in a frontal offset
collision. One of the vehicle's occupants is a child improperly restrained in a child booster seat. No weather-related factors are involved
on this spring afternoon.

On arrival at t he scene, you see that the police have secured and blocked traffic from the area around the crash. As your partner
and the other arriving crew are assessing the other patients, you approach the child. You see a young boy, approximately 2 years of age,
sitti ng in the booster seat, wh ich is slightly turned at an angle; there is blood on the back of the headrest of the seat in front of him.
Despite numerous abrasions and minor bleeding from the head, face, and neck, the child appears very calm.

Your primary and secondary assessments reveal a 2-year-old boy who weakly repeats "ma-ma, ma-ma." His pulse rate is 180 beats/
minute, w ith the radial pulses weaker than the carotid; his blood pressure is 50 mm Hg by palpation. His ventilatory rate is 18 breaths/
minute, slightly irregular, but without abnormal sounds. As you continue to assess him, you note that he has stopped saying "ma-ma"
and seems to just stare into space. You also note that his pupils are slightly dilated, and his skin is pale and sweaty. A woman who iden-
tifies herself as the family's nanny tells you that the mother is en route and that you should wait for her.

• What are the management priorities for this patient?
• What are the most likely injuries in this child?
• W here is the most appropriate destination for th is ch ild?

454 PREHOSPITAL TRAUMA LIFE SUPPORT, EIGHTH EDITION

You correctly identify this child as a victim of multisystem trauma who is in shock and critically injured. Because of the probable traumatic @
brain injury combined with the change in mentation, you have to determine the greatest threat to his survival-the brain injury and
other injuries not yet identified. You correctly identify hypotension and tachycardia, w hich you assume are related to hypovolemic shock,
probably the result of an unrecognized intra-abdominal injury.

Initially, the patient's breathing is supported with high-concentration oxygen through a nonrebreathing mask. You realize t hat his
ventilatory rate is low for a child of his age and are prepared to provide more aggressive airway control with a bag-mask if his condition
deteriorates. As you consider options for airway management, you ask your partner to hold manual stabilization of the head and neck.

Because of the nature of the ch ild's injuries, you consult with online medical control, who agrees t hat helicopter transport to the
closest pediatric trauma center is more appropriate than ground tra nsport to a nearby community hospital that has no pediat ric criti-
cal care, neurosurgical, or orthopedic resources. Brief efforts at peripheral venous access are successful. You begin crystalloid infusion
through the IV line. The ped iatric patient's mother arrives just as you are transferring care to the helicopter crew.

Your unit is dispatched to the home of a 78-year-old woman who has fallen down a flight of stairs. Her daughter states that they had
spoken on the telephone just 15 minutes earlier and that she w as coming to her mother's house to do some shopping. When she got
to the house, she found her mother on the floor and called for an ambulance.

Upon initial contact, you find the patient lying at the bottom of a flight of stairs. You note that the patient is an elderly w oma n

can cause an increased tolerance to pain, which may result in a
patient's failure to identify areas of injury. In evaluating patients,
especially those who usually "hurt all over" or who appear to have
a high tolerance to pain, areas in which the pain has increased
or in which the painful area has enlarged should be located. It
is also important to note whether the pain's characteristics or
exacerbating factors have changed since the trauma occurred.

Renal System

Changes common with aging include reduced levels of filtration
by the kidneys and a reduced excretory capacity. These changes
should be considered when administering drugs normally
cleared by the kidneys. Chronic renal inhibition typically affects
elderly persons and contributes to a reduction in a patient's over-
all health status and ability to withstand trauma. For example,
renal dysfunction may be one cause of chronic anemia, which
would lower a patient's physiologic reserve.
