## 문제

A nurse is caring for a patient with a known latex allergy who is scheduled for surgery. Which intervention should the nurse implement first to ensure patient safety?

## 보기

1. Create a latex-free environment in the operating room before the patient's arrival **✔ 정답**
2. Administer prophylactic antihistamines 30 minutes before surgery
3. Place an allergy alert bracelet on the patient's wrist
4. Ensure emergency medications are readily available in the operating room

**정답: 1**

## 해설

Creating a latex-free environment before patient arrival is the primary prevention strategy to avoid exposure. Other options are secondary or reactive measures.

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].References (research sources)

Clinical Practice Guide: Latex Allergy in the Perioperative Setting

1. Preoperative Assessment and Identification

Screen all patients for latex allergy risk factors, including multiple surgeries (especially in childhood), spina bifida, healthcare worker status, and known allergies to bananas, avocados, or kiwis. Document the allergy prominently in the chart and confirm with the patient directly.

2. Environmental Preparation (Primary Prevention)

Schedule the patient as the first case of the day when possible to minimize airborne latex particles. Coordinate with the operating room team to remove all latex-containing items, including gloves, catheters, tourniquets, stethoscope tubing, and medication vial stoppers. Stock the room exclusively with latex-free alternatives from a designated supply cart.

3. Communication and Safety Checks

Apply a red allergy alert bracelet immediately upon admission. Place a "Latex Allergy" sign on the patient's bed and the operating room door. Conduct a surgical time-out that includes verbal confirmation of the latex allergy and verification that a latex-free cart is available.

4. Pharmacological and Emergency Preparedness

Have emergency medications (epinephrine, antihistamines, corticosteroids) drawn up and immediately accessible in the operating room. Note that prophylactic premedication with antihistamines or steroids does not prevent anaphylaxis and should never replace strict allergen avoidance.

5. Postoperative Monitoring

Continue latex precautions into the post-anesthesia care unit. Monitor for delayed hypersensitivity reactions, which can occur hours after exposure. Ensure all hand-off reports include the patient's latex allergy status.

## 핵심 개념

- **Latex Allergy** — A hypersensitivity reaction to proteins found in natural rubber latex, which can range from contact dermatitis to life-threatening anaphylaxis.
- **Primary Prevention** — Interventions designed to prevent the initial occurrence of a disease or injury by removing the causative agent, such as creating a latex-free environment.
- **Anaphylaxis** — A severe, systemic, and potentially fatal allergic reaction that occurs rapidly upon exposure to an allergen, requiring immediate intervention.
- **Hypersensitivity Cascade** — The series of immunological events triggered by allergen exposure, leading to mast cell degranulation and release of inflammatory mediators like histamine.
