• “Stitch in the Side”

– Sharp pain or spasm in chest wall (lower) during exertion

– Etiology: varies

• “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

• Breast conditions

– Contusions

• Can produce fat necrosis or hematoma formation → ↑ pain

• Management: standard acute and external support

• 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

• 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

• Strain of pectoralis major

– MOI: active contraction; overburdened by excessive load or extrinsic force

• 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

• 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

• Costochondral sprain

– Etiology:

• Collision force

• Severe twisting of thorax

– Result: separates cartilage at attachment to rib or sternum

Undisplaced costochondral separation

• 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

• Sternal fracture

– Rare; requires high impact

– S&S

• Immediate loss of breath

• Pain, especially with deep inspiration

– Suspected fracture – assess for underlying injury

• Sternal fracture (cont’d)

– Management:

• Rib fracture

– Management:

• Standard acute; immobilize chest

• Severe: immediate referral to emergency care facility

• Internal injury suspected: activate emergency plan, including summoning of EMS

Internal ComplicationsInternal Complications

• Hyperventilation

– Etiology: pain, stress, trauma

– Rapid, deep inhalation – more O2

long exhalation – excessive CO2 loss

Internal Complications (cont’d)Internal Complications (cont’d)

• Hyperventilation (cont’d)

– S&S

• Inability to catch breath

• Chest pain

• Dry mouth

• Dizziness

• Hyperventilation (cont’d)

– Management:

• Slowly inhale through nose and exhale through mouth

• 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 complication to the lungs. A. Pneumothorax

• Hemothorax

– Loss of blood into pleural cavity

– Etiology: fracture of rib could tear lung tissue or blood vessels in chest

Internal complications to the lungs. B. Hemothorax

• Tension pneumothorax

– Air accumulates in pleural space during inspiration and cannot escape on exhalation; expansion compresses heart and lung

Internal complications to the lungs. C. Tension pneumothorax

• Pneumothorax, hemothorax, tension pneumothorax (cont’d)

– S&S

• Severe pain during breathing

• Hypoxia

• Cyanosis

• Signs of shock

• Concern: decreased cardiac output secondary to arrhythmias

• 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

• S&S

• Jugular venous distention

• Collapse within seconds and respiratory arrest

• Management

• activate emergency plan, including summoning EMS

• Initiate breathing and chest compressions

• 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

• Sudden Death in Athletes (cont’d)

• Grade 2 or 3 – physician referral

• Solar plexus contusion (“wind knocked out”)

– S&S

• Dyspnea

• Complicated by fear and anxiety

– Management:

• Flex the knees toward the chest

• Hernia

– Protrusion of abdominal viscera through weakened portion of abdominal wall

– Congenital or acquired

• Hernia (cont’d)

– S&S:

• Visible, tender swelling and an aching feeling in the groin

• If ruptures – a sharp, stinging pain or a feeling of something giving way at the site of the rupture, nausea and vomiting.

Intra-abdominal Conditions (cont’d)Intra-abdominal Conditions (cont’d)

• “Red flags” (cont’d)

– Localized tenderness and rigidity

– Cramps or muscle guarding

– Rebound pain

– Referred pain

• Trauma to abdomen (cont’d)

– Management:

• Activate emergency plan, may require summoning EMS

• Waiting for EMS

• Position individual supine with the knees flexed to relax the low back and abdominal muscles

• Splenic rupture

– Enlarged spleen: increases susceptibility

– Most frequent cause of death from abdominal blunt trauma in sport

– Ability to splint itself

– Individual with mononucleosis should be disqualified from contact & strenuous non-contact activities

– S&S

• Pain, tenderness

• Hematuria

• Pain referred posteriorly to low back region, sides of the buttocks, and anteriorly to lower abdomen

• Hypovolemic shock is possible

Coach and On-site Assessment of Throat, Thorax, and Abdominal Regions

• Assessment should focus on:

– Primary survey, history, and assessment of vital signs

– Caution:

• Trauma may appear superficial and minor, but mask internal hemorrhage

• Condition can slowly deteriorate into a life-threatening status

– Observation while approaching

• Overall presentation and attitude; willingness to move

• Body position – may indicate site, nature. and severity of injury

– Primary survey → assessment of vitals → history

– If any S&S suggest potentially life threatening condition, activate emergency plan, including summoning EMS

• Refer to Application Strategy 11.1
