Tyler Steele
Background scenario
It is 4:30 pm on a warm spring day in northwestern Washington State. You are a
community health nurse watching your teenage son play baseball. One of the coaches
approaches you with his arm around the shortstop, a 16 -year-old boy named Tyler
Steele. He says that Tyler is not feeling well. You lay Tyler down on the bench. Tyler's
friend Greg runs up to join you and the coach.
Interview
Tyler:
"I feel so weird. I'm scared."
"My skin is really itchy. It's getting worse really fast."
"It feels like my throat is swelling up."
"I'm having a hard time seeing. I can only see in the very middle."
"I'm having trouble breathing. I feel like I have asthma. I had it as a kid, but it went
away."
"I took a bunch of ibuprofen earlier so I could play."
Coach:
"He's never been sick during baseball. None of our players have been ill."
"He was fine during practice."
"He has had a strained Achilles tendon. We have been watching him quite a bit."
"I have his mom's phone number. I'll give her a call."
"Let me pull out his registration form. Here it is. It says he isn't allergic to anything."
Greg:
"Tyler! Did you get stung by one of those bees in the outfield?"
1
"Are you allergic to bee stings? My brother is and he gets itchy."
"Tyler took a couple of pills my dad gave me. I think it's called cats-flam or something
like that. It's just strong ibuprofen."
Examination
Vital signs:
Respiration: 21
Pulse: 120
Observation:
Client appears restless and seems to be getting "spacey".
He is itching and rubbing his arms and appears apprehensive.
Skin appears to have acquired a generalized edema.
There are small hives appearing on his neck area.
Occasionally, client places his hands on his upper chest.
He appears to be having some difficulty breathing.
Client is lying down and does not wish to lift his head.
He says he is dizzy. He is slow to answer questions, lethargic and appears to be losing
consciousness.
As time passes
You call 911 as Tyler loses consciousness. You monitor his airway, breathing, and
pulse until the paramedics arrive, about 3 minutes later. The paramedics record his
blood pressure as 76/40. They immediately administer Epinephrine 0.005 mg/kg
1:1000, and started an IV with normal saline. They administer Benadryl 50 mg IV and
transport Tyler to the hospital. The physician diagnoses Tyler as having a severe
allergic reaction to the Cataflam, an NSAID taken in addition to the ibuprofen he had
taken earlier.
Background education
Cataflam is a pain medication that contains the potassium salt of diclofenac. Diclofenac
is a nonsteroidal anti-inflammatory drug (NSAID) that belongs to the phenylacetic acid
group. Cataflam has strong analgesic, anti-inflammatory, and antipyretic properties. It
is an inflammatory degenerative and used for other painful conditions. Its mechanism of
action is the inhibition of the body's ability to synthesize prostaglandins, a family of
hormone-like chemicals created in response to cell injury. It also decreases
lipooxygenase products by enhancing the uptake of arachidonic acid into triglycerides.
Approximately 65% of the dose is excreted in the urine, and approximately 35% in the
bile. The common unwanted side effects are gastritis, peptic ulceration, and depression
of renal function. Anaphylaxis to diclofenac is an idiosyncratic reaction and is a very
2
rare event, but can occur in patients without prior exposure to diclofenac. Safety data
from clinical trials in the United States have shown that diclofenac has lower rates of
adverse reactions comparative NSAIDs.
In pain studies, the efficacy of Cataflam in 50-mg dose and 100-mg dosages is
comparable to aspirin 650 mg for immediate pain relief, but tended to provide a longer
duration of pain relief than aspirin. Cataflam 50 mg t.i.d. (three times a day) was
comparable in efficacy to ibuprofen 800 mg t.i.d. The dose of Cataflam in children over
14 years of age is up to 75 mg daily in divided doses. Cataflam is not recommended for
use in children 14 years of age or younger.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are very commonly used for pain relief.
Commonly known over the counter (OTC) NSAIDs include ibuprofen (Advil), aspirin
(Bayer), and naproxen (Naprosyn/Aleve). Prescription strength NSAIDs include
celecoxib (Celebrex), diclofenac sodium (Voltaren), indomethacin (Indocin) and
diclofenac potassium (Cataflam). NSAIDs allergic-type reactions occur in approximately
0.3% of the population.
Patients reacting to NSAIDs have anaphylactoid reactions which are believed not to be
immunologically mediated but due to direct suppression of prostaglandin synthesis.
The term anaphylaxis is commonly used for hypersensitivity reactions typically mediated
by immunoglobulin E (IgE). Anaphylactoid reactions are similar, but not related to
immune response hypersensitivity. These reactions are acute and include one or more
of the following: hypotension, bronchospasm, diffuse skin erythema, hives, itching,
laryngeal edema, or cardiac dysrrhythmia.
There is evidence that cross reactive to NSAIDs can occur in some aspirin sensitive
patients. Diclofenac is not recommended for asthmatic patients who experience rhinitis
with or without nasal polyps, or who exhibit bronchospasm after taking aspirin or other
nonsteroidal anti-inflammatory drugs. Fatal reactions have been reported in such
patients. It is not true, however, that an individual allergic to one NSAID is allergic to all
NSAIDs. Some individuals, who are allergic to one, can tolerate another type with no
adverse effects.
A severe anaphylactic reaction will cause rapid acute respiratory and circulatory
collapse, and can be fatal within minutes. Symptoms can be wide ranging. Often the
earliest symptoms are itching and warmth all over the body, accompanied by a feeling
of anxiety or panic. Other symptoms often seen in anaphylactic reaction include: hives,
flushing, wheezing, shortness of breath, bronchoconstriction, abdominal pain, nausea,
difficulty swallowing, vomiting, diarrhea, hypotension, dizziness or lightheadedness,
weakness, shock, pulmonary edema, angioedema, swelling of the face, eyes, or
tongue, unconsciousness seizures, coma, and death.
Treatment begins with the basics. Immediately stop the exposure or administration of
any substances that might be causing the reaction. Establish airway, breathing, and
circulation. Administer oxygen by face mask at 6 to 8 L/minute, administer epinephrine
3
subcutaneously, start an IV, intubate if needed, administer a rapidly acting steroid IV,
administer an antihistamine IV, and monitor the client.
Epinephrine is a key treatment to reverse the symptoms of aphylactic reactions. As an
alpha-receptor agonist, it reverses peripheral vasodilatation and swelling. It opens the
airways, and increases the force of myocardial contraction.
Individuals who have experienced allergic reactions to a food or medication need to be
vigilant to avoid a repeat experience. Community health nurses can help them identify
what caused the reaction and work with employers, teachers, or family members to help
the individual avoid another exposure. This includes informing others of the allergy.
Individuals may wear a medic-alert bracelet or necklace or carry a medic-alert card in
purse or wallet.
In addition, the physician may prescribe emergency Epinephrine for the individual to
keep at hand in case another reaction occurs. Epinephrine is available in auto-injectors,
commonly known as EpiPens. These are disposable drug systems with spring
activation of a concealed needle for a rapid, convenient dose of Epinephrine in an
emergency situation. The EpiPen is pushed firmly into the thigh, and held for 10
seconds. It is then removed and discarded. The expiration date on the EpiPen must be
checked, and the device replaced when it is outdated.
