Allergy history, latex safety and anaphylaxis on the ward: the first nursing response
- Assessment
The nurse records every allergy, keeps latex away from allergic patients and, if anaphylaxis starts, stops the trigger, calls for help and prepares epinephrine.
What it is
Anaphylaxis is a life-threatening, whole-body allergic reaction that often begins within seconds or minutes of the trigger: a medicine, a food, a sting or latex. On the ward, prevention starts with a careful allergy history, a visible record and a latex-safe environment for patients who need it. When a reaction starts, the first minutes matter: remove the trigger, call for help, assess airway, breathing and circulation, and give intramuscular epinephrine, the first-line treatment, according to the institutional protocol. Antihistamines and corticosteroids are second-line and never replace it. Because a second reaction can follow hours later, the patient keeps being observed after improving.
Reference values
- Signs of anaphylaxis: hives, itching or redness; swelling of the face, eyes or tongue; wheeze, cough or chest tightness; dizziness; nausea, vomiting or diarrhoea; slurred speech or collapse.
- Hospital items that may contain latex: some gloves, catheters and tubing, tourniquets, medicine vials, elastic bandages.
- Higher risk of latex allergy: health workers, people who have had many operations, people with spina bifida or urinary tract defects.
- Some people with latex allergy also react to foods such as banana, avocado or chestnut.
How to measure it (and why)
- On admission, ask about allergies to medicines, foods, latex and others, and what reaction happened: the reaction type shows how serious it was.
- Record the allergy in the chart and tell pharmacy and food services: they must not use the trigger or latex gloves when preparing medicines or food.
- Check the allergy record before every medicine; if the patient is allergic to it, do not prepare it and notify the prescriber.
- For latex allergy, use non-latex gloves and equipment, remove latex items from the room and place a sign as the institution allows.
- If a reaction starts during a medicine or infusion, stop it at once and call for help: removing the trigger limits the reaction.
- Assess airway, breathing, circulation, consciousness and skin; start CPR if needed.
- Prepare intramuscular epinephrine as the doctor orders or as the anaphylaxis protocol states: it is the first-line treatment.
- Lay the patient flat; sit them up if breathing is hard, on the left side if pregnant, in the recovery position if unconscious.
- Give nothing by mouth if breathing is difficult; give oxygen, help place a wide-bore IV line and monitor vital signs often, as ordered.
- Keep observing after the patient improves and record and report the event: a second reaction can follow hours later.
How to read it
- Hives or swelling together with breathing trouble, dizziness or collapse after a trigger point to a whole-body reaction, not a simple rash.
- Mild latex reactions: dry itchy skin, hives, watery eyes, runny nose, scratchy throat. Severe: trouble breathing or swallowing, fainting, signs of shock.
- Breathing in powder from latex gloves can also trigger a reaction.
- A reaction to an injected medicine can appear within minutes or even days.
Next step: when to call for help
- Breathing difficulty, throat swelling, a hoarse voice, falling blood pressure or collapse: call the emergency team at once.
- Hives or swelling after a new medicine: stop it, notify the doctor and file the incident report.
- Symptoms coming back hours after the patient improved: call the doctor at once.
- Before discharge after anaphylaxis, check that the team has planned an epinephrine auto-injector, a written action plan and an allergy referral.
Test yourself
Think of the answer, then tap the question to see it.
What is the first-line treatment for anaphylaxis, and where is it given?
Epinephrine by intramuscular injection into the outer thigh, as ordered or per the institutional protocol. Antihistamines and corticosteroids are second-line.
What does the nurse do first if a reaction starts during an infusion?
Stops the infusion to remove the trigger, calls for help and assesses airway, breathing and circulation.
Why is a patient still observed after recovering from anaphylaxis?
A second (biphasic) reaction can follow; about half occur within 6–12 hours.
Which patients have a higher risk of latex allergy?
Health workers, people who have had many operations, and people with spina bifida or urinary tract defects.
