Introduction

Athletic trainers must be prepared to recognize, prevent, and manage environmental cold injuries to ensure athlete safety.
Cold exposure can lead to conditions such as hypothermia, frostbite, and immersion foot, all of which require immediate and informed intervention.
The National Athletic Trainers’ Association (NATA) has established a Position Statement on Environmental Cold Injuries to guide best practices in prevention and treatment. For students preparing for the BOC exam, understanding this position statement is crucial for both passing the exam and excelling in professional practice.

This guide will break down key aspects of the NATA Position Statement, focusing on definitions, prevention strategies, treatment protocols, and real-world case applications. A study guide is also included at the end to help reinforce key concepts for the BOC exam.

Understanding Environmental Cold Injuries

Cold injuries occur when the body is unable to maintain a normal core temperature due to prolonged exposure to cold, wet, or windy conditions. These injuries fall into three primary categories:

1. Hypothermia

• Definition: A drop in core body temperature below 95°F (35°C).
• Stages:
  • Mild (95°F-98.6°F): Shivering, lethargy, amnesia.
  • Moderate (90°F-94°F): Depressed respiration, slurred speech, impaired motor function.
  • Severe (<90°F): Muscle rigidity, unconsciousness, risk of cardiac arrest.

2. Frostbite

• Definition: Freezing of tissues due to prolonged exposure to cold temperatures.
• Types:
  • Superficial Frostbite: Waxy skin, numbness, limited movement.
  • Deep Frostbite: Hard, cold skin, tissue necrosis, blistering, high risk of permanent damage.

3. Chilblain (Pernio) & Immersion (Trench) Foot

• Chilblain: Prolonged exposure to cold, wet conditions leads to red, swollen, itchy skin.
• Immersion Foot: Extended exposure to cold water causes numbness, tingling, and increased infection risk.

Key Prevention Strategies for Cold Injuries

Preventing cold-related injuries requires proactive planning. The NATA Position Statement outlines the following best practices:

1. Pre-Participation Screening

• Identify athletes at higher risk, including those with previous cold injuries, low body fat, or conditions like Raynaud’s syndrome.
• Conduct cold exposure history assessments as part of medical evaluations.

2. Environmental Risk Assessment

• Monitor wind chill temperatures and modify practices when conditions pose a risk.
• Plan for alternative training options in severe weather.
• Educate athletes and coaches about recognizing cold injury symptoms.

3. Proper Clothing and Gear

• Layering System:
  • Base layer: Moisture-wicking fabric to keep skin dry.
  • Middle layer: Insulation (fleece, wool) to retain heat.
  • Outer layer: Windproof and waterproof materials.
• Use hats, gloves, and insulated footwear to protect extremities.

4. Hydration & Nutrition

• Maintain fluid intake, as cold-induced diuresis increases dehydration risk.
• Ensure adequate caloric intake to support metabolic heat production.

5. Emergency Action Planning

• Have heated shelters or warm indoor spaces available.
• Keep dry clothing, blankets, and heat packs on hand.
• Train staff on immediate response strategies for cold injuries.

Immediate Care and Treatment Guidelines

Once an athlete exhibits signs of a cold injury, rapid intervention is necessary.

Hypothermia Treatment

1. Mild Hypothermia:
   • Move to a warm environment.
   • Provide warm, non-alcoholic, non-caffeinated beverages.
   • Apply dry clothing and blankets.
2. Moderate/Severe Hypothermia:
   • Activate Emergency Medical Services (EMS).
   • Remove wet clothing and apply external heat sources (torso only to prevent afterdrop).
   • Monitor vital signs and consciousness level.

Frostbite Treatment

• Superficial Frostbite:
  • Rewarm with skin-to-skin contact or warm water immersion (98°F-104°F).
  • Avoid rubbing the skin, as this can worsen tissue damage.
• Deep Frostbite:
  • Do not attempt rewarming if refreezing is possible.
  • Seek immediate medical attention.
  • Administer pain management as thawing can be extremely painful.

Chilblain & Immersion Foot Treatment

• Remove wet clothing and gently warm the area.
• Avoid direct heat exposure.
• Monitor for signs of infection.

Case Studies & Real-World Applications

Case Study 1: Cross-Country Runner in Freezing Temperatures

• A collegiate runner experiences numb toes and waxy skin after a long training session in subzero temperatures.
• Diagnosis: Mild frostbite.
• Management: Superficial rewarming, monitoring for blistering, and education on proper footwear and layering.

Case Study 2: Football Player with Hypothermia

• A high school football player collapses after a late-season game in sleet and wind.
• Symptoms: Confusion, shivering, weak pulse.
• Management: Moved to a heated locker room, removed wet gear, wrapped in warm blankets, and given warm fluids.

Conclusion

Cold injuries are a serious concern for athletic trainers, especially those working in outdoor sports. Understanding the NATA Position Statement on Environmental Cold Injuries is essential for preventing and managing these conditions effectively.
By implementing proactive strategies and following evidence-based treatment guidelines, athletic trainers can ensure the safety and performance of their athletes.

For BOC exam success, mastering these concepts will not only help answer test questions but also enhance real-world clinical decision-making skills.
