A nurse is caring for a patient with a known latex allergy who is scheduled for surgery. Which action by the nurse demonstrates the most appropriate safety measure?
1Schedule the patient as the first case of the day in any available operating room
2Ensure all staff members wear powder-free latex gloves during the procedure
3Create a latex-free environment by using non-latex gloves and latex-free equipment✓ 정답
4Administer prophylactic antihistamines 30 minutes before the procedure
해설
Creating a latex-free environment is the most appropriate safety measure as it prevents exposure to latex allergens. Other options, such as scheduling or using powder-free latex gloves, do not eliminate the risk of anaphylaxis.
Understanding Latex Allergy and Perioperative Safety
Latex allergy is a hypersensitivity reaction to proteins found in natural rubber latex. In susceptible individuals, exposure can trigger a spectrum of responses, ranging from contact dermatitis to life-threatening anaphylaxis. The cornerstone of safe care for a patient with a known latex allergy is complete avoidance of all latex-containing products. This principle is supported by the position paper on occupational anaphylaxis, which identifies natural rubber latex as a significant trigger for systemic allergic reactions in the workplace, including healthcare settings [3]. The goal is to prevent the initiation of an allergic cascade, which can occur not only through direct skin or mucous membrane contact but also via inhalation of latex proteins that bind to the powder inside gloves and become aerosolized.
Analysis of Answer Choices
- Option 1: Scheduling the patient as the first case of the day can reduce exposure to airborne latex particles that may have accumulated from previous procedures. However, this measure is insufficient on its own. An operating room that has not been thoroughly cleaned of latex dust or is still stocked with latex-containing equipment does not constitute a safe environment. Complete avoidance is the standard, not merely a reduction in potential aerosolized particles.
- Option 2: Ensuring staff wear powder-free latex gloves is contraindicated. While powder-free gloves release fewer aerosolized latex proteins than powdered ones, they still contain the allergenic latex proteins. A study on glove integrity highlights that even powder-free latex gloves are a source of latex exposure [1]. This action would place the patient at significant risk for a hypersensitivity reaction. The correct intervention is to use non-latex alternatives, such as nitrile or neoprene gloves.
- Option 3 (Correct Answer): Creating a latex-free environment is the definitive and most appropriate safety measure. This involves a comprehensive approach: using non-latex gloves, latex-free tourniquets, stethoscopes, blood pressure cuffs, IV tubing ports, and syringes. A practical review of surgical glove materials confirms that synthetic alternatives like nitrile and neoprene provide effective barrier protection without the allergy risk associated with latex [2]. This action directly aligns with the preventive management strategies for latex-induced anaphylaxis by eliminating the trigger entirely [3].
- Option 4: Administering prophylactic antihistamines is not a substitute for allergen avoidance. While antihistamines may blunt the early cutaneous signs of a mild allergic reaction, they are unreliable in preventing anaphylaxis, which is a multi-system, mast-cell mediated event involving more than just histamine release. Relying on premedication without establishing a latex-free environment creates a false sense of security and leaves the patient vulnerable to a severe, potentially fatal reaction.
Clinical Safety Rationale
The pathophysiology of IgE-mediated latex allergy involves sensitization and subsequent mast cell degranulation upon re-exposure. The most effective preventive strategy is complete antigen avoidance. A "latex-free" protocol is a system-based safety measure that requires meticulous attention to the entire perioperative environment, from the gloves the surgical team wears to the materials in the anesthesia circuit. The evidence clearly indicates that synthetic glove materials provide a safe and effective alternative, eliminating the risk of triggering a life-threatening allergic event [2,3].

Clinical Practice Guide: Latex Allergy in Perioperative Care
1. Preoperative Identification and Preparation
Screen all surgical patients for latex allergy using a specific allergy history questionnaire, not just a general allergy band.
If a latex allergy is confirmed or strongly suspected, flag the patient's chart, wristband, and operating room schedule prominently with a non-latex alert.
Schedule the patient as the first case of the day in a designated latex-free operating room to minimize exposure to residual airborne latex particles from previous procedures.
2. Creating a Latex-Free Environment
Remove all latex-containing products from the operating room and anesthesia cart. This includes but is not limited to gloves, tourniquets, catheters, stethoscope tubing, and medication vial stoppers.
Stock the room exclusively with synthetic alternatives such as nitrile or neoprene gloves, silicone catheters, and latex-free syringes.
Ensure a latex-free cart or kit is readily available and that its contents are verified against a checklist before the patient enters the room.
3. Intraoperative Monitoring and Emergency Response
All staff entering the room must wear non-latex gloves; powder-free latex gloves are not an acceptable substitute as they still contain allergenic proteins.
Have emergency medications, including epinephrine, immediately accessible at the bedside for treating anaphylaxis, as antihistamines alone are insufficient for prophylaxis or treatment of a systemic reaction.
Continuously monitor for signs of an allergic reaction, including unexplained hypotension, bronchospasm, or urticaria, as reactions can occur from hidden latex sources.
4. Postoperative and Documentation Considerations
Document the latex-free status of the procedure and any allergic reactions in the operative report and patient record.
Communicate the latex allergy status during handoff to post-anesthesia care unit (PACU) and floor nurses to maintain a latex-free environment throughout recovery.
Provide the patient with education on hidden sources of latex in the community and a list of alternative products for future healthcare encounters.
Latex Allergy — A hypersensitivity reaction to proteins in natural rubber latex, ranging from contact dermatitis to life-threatening anaphylaxis upon contact or inhalation.
Anaphylaxis — A severe, systemic allergic reaction that can be triggered by latex exposure, requiring complete antigen avoidance as the primary prevention strategy.
Latex-Free Environment — A clinical setting where all latex-containing products, including gloves, catheters, and tourniquets, are replaced with synthetic alternatives to prevent allergic reactions.
Aerosolized Latex Proteins — Latex allergens that bind to glove powder and become airborne, causing respiratory or systemic reactions upon inhalation by sensitized individuals.
