What is the recommended on-field treatment for SCT?

• A. Hydration and continue playing
• B. Continue activity with oxygen only if symptoms worsen
• C. Immediate withdrawal from activity; high-flow O2 at 15 L/min with a non-rebreather mask; monitor vitals and activate EAP; be prepared to treat explosive rhabdomyolysis
• D. Apply cold packs

Answer: (C)

Exertional sickle cell trait can cause red blood cells to sickle under strenuous exercise, dehydration, or heat, leading to muscle injury, impaired blood flow, and even rapid rhabdomyolysis. The on-field plan is to remove the athlete from activity immediately and begin aggressive supportive care to prevent progression. Immediate withdrawal from play stops the triggering stress and prevents further hypoxia in the muscles. Delivering high-flow oxygen, about 15 L/min, through a non-rebreather mask raises the fraction of inspired oxygen, helping keep blood and tissues fully oxygenated and reducing the tendency for sickling. Monitoring vital signs enables early detection of deterioration and guides urgent decisions, while activating the Emergency Action Plan ensures rapid access to advanced care and transport. Being prepared to treat explosive rhabdomyolysis means recognizing that muscle breakdown can occur quickly in SCT under exertion, releasing toxins that can damage the kidneys and disrupt electrolytes. Early recognition and treatment mitigate these risks. Hydration alone and continuing activity don’t address the underlying risk of hypoxia and sickling, and cold packs don’t address the primary threat.
