Managing Severe Food Allergies and School Anaphylaxis Emergency Protocols in Preschools

The most pervasive hazard in preschools is medical isolation—storing allergy information in physical medical binders locked in health rooms while kitchen staff and relief educators remain uninformed:

• Mandatory Admission Health Disclosure: Parents must document comprehensive allergy histories, familial atopy, severity grading (mild, moderate, or anaphylactic), and confirmed allergens including cow's milk, eggs, peanuts, shellfish, soy, or sesame.
• Digital Allergen Badging: Each allergic child's profile receives a persistent red high-alert badge that automatically propagates to classroom attendance rosters and central kitchen display terminals.
• Real-Time Automated Menu Cross-Checking: When the head chef prepares daily or weekly menus, the system cross-references each ingredient against enrolled children with scheduled attendance. An alert triggers immediately if an ingredient matches an allergic child's medical profile.
• Mandatory Safe Substitute Approval: The platform requires culinary staff to configure and confirm nutritionally equivalent substitute dishes (e.g., lean ground pork instead of shrimp) prior to issuing kitchen preparation orders.

Allergen cross-contact occurs when microscopic proteins inadvertently transfer from one food item to another via hands, cutting surfaces, frying oil, or shared cooking utensils:

• Dedicated Hypoallergenic Preparation Station: Institutional kitchens must allocate an isolated stainless steel prep bench dedicated exclusively to allergen-free meals, equipped with independent cookware.
• High-Visibility Red Tray & Crockery System: All allergic meals are served on distinct bright red compartmentalized trays with transparent snap-on lids labeled with child name, class, and specific excluded allergens.
• Independent Sanitization Protocols: Hypoallergenic prep tools are hand-washed with dedicated sponges and hot water, preventing contact with washing sinks containing residues of peanuts or crustacean shells.
• Direct Chain-of-Custody Classroom Handoff: Dining distribution staff deliver red trays directly into the hands of lead classroom teachers with verbal and written verification, never stacking them alongside standard meal trays.

Anaphylaxis can rapidly progress from mild cutaneous signs to fatal respiratory obstruction and circulatory collapse within minutes:

• Grade 1 (Mild Severity): Manifests solely through skin and mucosal signs such as localized urticaria, generalized pruritus, lip tingling, periorbital edema, or facial flushing.
• Grade 2 (Moderate/Severe): Involves two or more organ systems: throat tightness, stridor, mild wheezing, abdominal cramps, vomiting, diarrhea, tachycardia, or blood pressure fluctuations.
• Grade 3 (Critical/Life-Threatening): Characterized by acute laryngeal spasm, severe respiratory distress, cyanosis, hypotension or unmeasurable blood pressure, thready pulse, lethargy, or altered consciousness.
• Grade 4 (Cardiopulmonary Arrest): Sudden respiratory arrest, pulseless electrical activity, or complete cardiovascular collapse immediately following ingestion or allergen contact.

Pursuant to MOH Circular 51/2017/TT-BYT, intramuscular Adrenaline is the sole frontline life-saving therapeutic and must be administered immediately upon recognizing Grade 2 or higher anaphylaxis without hesitation:

• Readiness of Emergency Anaphylaxis Kits: Every campus health station and central office must maintain a certified anaphylaxis kit containing unexpired 1mg/1ml Adrenaline ampoules, sterile syringes, alcohol prep pads, and laminated dosage algorithms.
• Adrenaline Auto-Injectors (EpiPen Integration): Schools encourage families of high-risk children to provide prescribed auto-injectors, with school staff undergoing hands-on auto-injector deployment training.
• Pediatric Intramuscular Dosage Guidelines: Children weighing under 10kg receive 0.15ml (1/6 ampoule); children from 10 to 25kg receive 0.25 to 0.3ml (1/4 to 1/3 ampoule) injected anterolaterally into the mid-thigh. Repeat in 3 to 5 minutes if symptoms persist.
• Emergency Alarm & 115 Ambulance Activation: Concurrently with the first injection, place the child in a supine position with elevated legs (lateral recumbent if vomiting), initiate oxygen therapy, and contact 115 emergency services immediately.
• Biannual Simulation Drills: All teaching faculty and support personnel must participate in biannual simulated emergency drills using training auto-injectors to eliminate hesitation during real-world crises.
