The Thorax and Abdomen Flashcards
Thoracic Cavity
Commonly known as the chest, which lies between the base of the neck and the diaphragm. It consist of the thoracic vertabrae, the 12 pairs of ribs with their associated costal cartilages, and the sternum.
Its main functions are to protect the vital respiratory and circulatory organs and to assist the lings in inspiration and expiration during breathing.
Ribs
Upper 7 = Sternal/True ribs because each rib is joined to the sternum by a separate costal cartilage.
8-10 = False ribs have a common cartilage that joins the 7th rib before attaching to the sternum.
11th and 12th = Floating ribs that are unattached to the sternum (they do have muscle attachments).
External Intercostal Muscles
Elevate the diaphragm during inspiration.
Internal Intercostal Muscles
Depress the rib cage to assist with expiration.
Rib Contusion
Blow to the rib cage.
Sx's: Painful breathing (particularly if muscles are involved). Point tenderness.
Management:
RICE and NSAID’s
Rest and decrease in activity.
Rib Fractures
Direct blow or result of violent muscular contraction.
Can be caused by violent coughing and sneezing
Signs and Sx’s:
History is critically important.
Pain with inspiration, point tenderness and possible deformity with palpation.
Management:
refer for x-rays
Support and rest/brace.
A big concern with a rib fracture is a rib that can puncture an organ.
Flail Chest
3+ consecutive ribs are fractures.
Costochondral Separation
Direct blow to the anterolateral aspect of the rib cage.
Sign’s and Sx’s:
Localized pain at the costochondral junction.
Pain with movement; difficulty breathing
Point tenderness and possible deformity.
Management:
Rest and immobilization
Healing may take 1-2 months (a very slow healing process).
Sternum Fractures
Caused by a high impact blow to the chest. Underlying cardiac muscles may also by contused.
Sign’s and Sx’s:
Point tenderness over the sternum.
Pain with deep inspiration and forceful expiration.
Signs of shock, or weak rapid pulse may indicate more severe injuries.
Management:
Refer for x-ray.
Monitor athlete for signs of trauma to the heart.
Muscle Injuries
Direct blows or sudden torsion of the trunk
Sign’s and Sx’s
Pain with active motions
Pain with inspiration and expiration, coughing, sneezing or laughing.
Management:
Immediate pressure.
Application of cold.
Immobilize the injury for athlete comfort.
Lung Injuries
Pneumothorax
Tension Pneumothorax
Hemothorax.
Traumatic Asphyxia
Management:
Medical emergencies that require immediate attention.
Transport Immediately
Hyperventilation
Anxiety, stress or asthma induced.
Develop a decreased amount of carbon dioxide relative to oxygen.
Sign’s and Sx’s
Difficulty inhaling and struggling to breath
In a panic state
Gasping and wheezing.
Management: Decrease rate of carbon dioxide loss Slow down respiration rate Breath into a bag Normal respiration should return within 1-2 minutes Initial cause must be determined.
Sudden Cardiac Death Syndrome
Look at slides.
Commotio Cordis
A syndrome resulting in cardiac arrest due to traumatic blunt impact to the chest. It is an unfortunate timing relative to re-polarization phase of the cardiac cycle. Younger athletes are at risk.
Signs and Sx’s
Ventricular fibrillation.
Management:
Resuscitation of victim is seldom successful.
Early de-fibrillation with AED and resuscitation is critical.
Heart Contusion
Compression between sternum and spine - could cause an aortic rupture.
Sign’s and Sx’s:
Severe shock and heart pain
Heart may exhibit arrhythmias causing a decrease in cardiac output, followed by death if medical attention is not administered.
Management:
Immediate referral to an emergency room
Prepare to administer CPR and treat for shock.
