🛡️ Chapter 727 · Prevention of Injuries

Nelson Textbook of Pediatrics 22nd Edition | Preparticipation Sports Examination (PPE): performed 3-6 weeks before season, identifies problems in 1-8% of athletes, excludes <1%. Cardiac screening: family history of sudden death, syncope, chest pain with exercise. Conditions: hypertrophic cardiomyopathy (most common cause of sudden death), anomalous coronary arteries, long QT, Marfan syndrome. Heat illness prevention: acclimatization, hydration, avoid high heat/humidity. Concussion: remove from play, return to learn then return to play. Injury prevention: neuromuscular training (ACL prevention), ankle bracing, mouth guards (dental injuries). COVID-19 return to play: graded protocol based on severity (mild → cardiac eval if symptoms).

📋 Stepwise Approach: Preparticipation Exam & Injury Prevention

🔑 Key Principles — Nelson Chapter 727
• PPE objectives: Identify conditions limiting participation, prevent injury, detect cardiac risk (hypertrophic cardiomyopathy, long QT, Marfan). 75% of significant findings from history.
• Cardiac red flags: Syncope with exercise, chest pain, palpitations, dyspnea > peers, family history of sudden death <50 years, hypertrophic cardiomyopathy, long QT, Marfan.
• Sports classification: Contact (football, hockey, wrestling) vs non-contact. Dynamic vs static (Fig 727.2).
• Heat illness prevention: Acclimatization (8-12 days), hydration, avoid high heat index. Heat stroke: cold water immersion.
• Concussion: Remove from play, return to learn first, then graduated return to play (Table 729.2).
• COVID-19 return to play: Graded based on severity (mild → no cardiac eval; moderate/severe/MIS-C → cardiology eval).
