Throat Conditions (cont’d) • Contusions and fractures (cont’d) • Management: • Calm individual; help individual focus on their breathing rate • Significant trauma • Activate emergency plan, including summoning EMS • Assess vitals and treat as necessary
Thoracic Conditions • Sudden deceleration and impact → compression and deformation of rib cage • “Red Flags” • Shortness of breath or difficulty in breathing • Deviated trachea or trachea that moves during breathing • Anxiety, fear, confusion, or restlessness
Thoracic Conditions (cont’d) • “Red Flags” (cont’d) • Distended neck veins • Bulging or bloodshot eyes • Suspected rib or sternal fracture • Severe chest pain aggravated by deep inspiration
Thoracic Conditions (cont’d) • “Red Flags” (cont’d) • Abnormal chest movement on affected side • Coughing up bright red or frothy blood • Abnormal or absent breath sounds • Rapid, weak pulse • Low blood pressure • Cyanosis
Thoracic Conditions (cont’d) • “Stitch in the Side” • Sharp pain or spasm in chest wall (lower) during exertion • Etiology: varies
Thoracic Conditions (cont’d) • “Stitch in the Side” (cont’d) • Management: Most individuals can run through the sharp pain by: • Forcibly exhaling through pursed lips • Breathing deeply and regularly • Leaning away from the affected side • Stretching the arm on the affected side over the head as high as possible
Thoracic Conditions (cont’d) • Breast conditions • Contusions • Can produce fat necrosis or hematoma formation → ↑ pain • Management: standard acute and external support
Thoracic Conditions (cont’d) • Breast conditions (cont’d) • Nipple irritation • Runner’s nipples • Friction → abrasions, blisters, or bleeding • Management: advise individual to cleanse and cover the wound; if infection is a concern, physician referral • Prevention: petroleum-based product
Thoracic Conditions (cont’d) • Breast conditions (cont’d) • Cyclist’s nipples • Perspiration + wind chill → ↑ pain • Management: warm the area after the event to prevent irritation • Prevention: wind-proof jacket
Thoracic Conditions (cont’d) • Strain of pectoralis major • MOI: active contraction; overburdened by excessive load or extrinsic force
Thoracic Conditions (cont’d) • Strain of pectoralis major (cont’d) • S&S • Sound: pop or tearing • Immediate pain and weakness; aching or fatigue-like rather than sharp pain • Deformity – muscle retracts • Swelling and ecchymosis • Limited shoulder motion due to pain
Thoracic Conditions (cont’d) • Strain of pectoralis major • Management: • Grade 1 – standard acute; if the condition does not resolve in 2-3 days, physician approval prior to return to activity • Grade 2 or 3 – physician referral
Thoracic Conditions (cont’d) • Costochondral sprain • Etiology: • Collision force • Severe twisting of thorax • Result: separates cartilage at attachment to rib or sternum Undisplaced costochondral separation
Thoracic Conditions (cont’d) • Costochondral sprain (cont’d) • S&S • Hear or feel a “pop” • Localized sharp pain; changes to intermittent stabbing pain • Visible deformity • Severe: pain with deep inhalation • Management: standard acute; physician referral
Thoracic Conditions (cont’d) • Sternal fracture • Rare; requires high impact • S&S • Immediate loss of breath • Pain, especially with deep inspiration • Suspected fracture – assess for underlying injury
Thoracic Conditions (cont’d) • Sternal fracture (cont’d) • Management: • Activate emergency plan, including summoning EMS • Assess vitals and treat as necessary
Thoracic Conditions (cont’d) • Rib fracture • Stress fracture – indirect force (muscle contraction) • Acute • Direct blow or compression • Ribs 5-9 • Most minor – undisplaced; if displaced, suspect internal injury
Thoracic Conditions (cont’d) • Rib fracture (cont’d) • S&S • Pain at site with deep inspiration or coughing • Individual will take shallow breaths and lean toward fracture site • Localized swelling, discoloration, crepitus
Thoracic Conditions (cont’d) • Rib fracture (cont’d) • S&S (cont’d) • Check for: • Coughing up of blood • Abnormal breath sounds • Rate and depth of respiration
Thoracic Conditions (cont’d) • Rib fracture (cont’d) • Management: • Standard acute; immobilize chest • Severe: immediate referral to emergency care facility • Internal injury suspected: activate emergency plan, including summoning of EMS
Internal Complications • Hyperventilation • Etiology: pain, stress, trauma • Rapid, deep inhalation – more O2long exhalation – excessive CO2 loss
Internal Complications (cont’d) • Hyperventilation (cont’d) • S&S • Inability to catch breath • Numbness in lips and hands • Spasm of hands • Chest pain • Dry mouth • Dizziness
Internal Complications (cont’d) • Hyperventilation (cont’d) • Management: • Calm individual • Slowly inhale through nose and exhale through mouth
Internal Complications (cont’d) • Pneumothorax • Air trapped in pleural space, causing portion of lung to collapse; lung can’t fully expand • Etiology • Traumatic – penetrating wound • Spontaneous – unexpectedly without underlying disease
Internal Complications (cont’d) Internal complication to the lungs. A. Pneumothorax
Internal Complications (cont’d) • Hemothorax • Loss of blood into pleural cavity • Etiology: fracture of rib could tear lung tissue or blood vessels in chest
Internal Complications (cont’d) Internal complications to the lungs. B. Hemothorax
Internal Complications (cont’d) • Tension pneumothorax • Air accumulates in pleural space during inspiration and cannot escape on exhalation; expansion compresses heart and lung
Internal Complications (cont’d) Internal complications to the lungs. C. Tension pneumothorax
Internal Complications (cont’d) • Pneumothorax, hemothorax, tension pneumothorax (cont’d) • S&S • Severe pain during breathing • Hypoxia • Cyanosis • Signs of shock • Hemothorax – coughing up frothy blood may also be seen
Internal Complications (cont’d) • Pneumothorax, hemothorax, tension pneumothorax (cont’d) • Management: • Activate emergency plan, including summoning EMS • Assess vitals and treat as necessary
Internal Complications (cont’d) • Heart injuries • Blunt cardiac injury • Leads to localized damage and necrosis of heart tissue • Concern: decreased cardiac output secondary to arrhythmias
Internal Complications (cont’d) • Heart injuries (cont’d) • Blunt cardiac injury (cont’d) • Cardiac tamponade • Ruptures myocardium or lacerates coronary artery; ↑ fluid in pericardium; compresses venous return to heart
Internal Complications (cont’d) • Heart injuries (cont’d) • Blunt cardiac injury (cont’d) • S&S • Jugular venous distention • Collapse within seconds and respiratory arrest
Internal Complications (cont’d) • Heart injuries (cont’d) • Blunt cardiac injury (cont’d) • Management • activate emergency plan, including summoning EMS • Initiate breathing and chest compressions
Internal Complications (cont’d) • Sudden Death in Athletes • Sudden death – an event that is non-traumatic, unexpected, and occurs instantaneously or within minutes of an abrupt change in an individual’s previous clinical state • Causes: hypertrophic cardiomyopathy; abnormalities in the coronary arteries; aortic rupture associated with Marfan’s syndrome; and mitral valve prolapse
