Chest Injuries Flashcards
Chest injuries
Any injury to the chest can impair breathing and cause hypoxia.
If left untreated chest injuries can cause one or both lungs to collapse, putting pressure on the heart and ultimately leading to cardiac arrest.
If lung collapses, now have a space between the two pleura. Things can then fill this space (e.g air or blood). The more air that gets into the cavity, the more the pressure increases inside the cavity. This squeezes other organs over.
Two main categories of chest injuries…
Closed and open chest injuries
Closed v open chest injuries
Closed: skin is not broken, but there may be damage to internal organs.
E.g. can happen in a RTC.
Air does not have access through the chest wall (so no hole on the outside)
Open:
Foreign objects can penetrate the chest wall from outside the body
Broken ribs can penetrate the chest wall from inside the body
Air can enter the chest cavity
What are the mechanisms for chest injuries
Blunt trauma:
a blow to the chest can fracture ribs
Damage to underlying organs can occur with or without fractured ribs.
Penetrating trauma:
Bullets, knives, pieces of metal, wood or glass can penetrate the wall.
Compression
Is a rapid action
Rapid compression of the chest can occur during a RTC.
Impaled objects
Do not remove (could be acting as a plug, stemming the blood)
Handle carefully
Secure the object with a dressing
If pulsating, do not completely immobilise the object, allow it to pulsate.
dont let patient remove it
Signs and symptoms of a fracture
Bruising Swelling Loss of motor function Irregularities Pain Deformity Unnatural movement Crepitus Tenderness
All these things can be personal and may not show straight away
Fractured rib
Exhibit usual sign of a fracture
Identify Mechanism that caused injury and what are likely results of this/ potential injuries.
Pain usually made worse by deep inspiration and coughing
Be aware that the end of a broken rib could pierce and puncture a lung, causing a pneumothorax.
Multiple rib fractures interfere with mechanism of breathing and can create life threatening situations.
What is a flail segment
Two or more rib fractures in two or more places.
So we end up with a section that isn’t attached to the rib cage anymore. This is going to get sucked in when we breathe in as diaphragm moves up and out.
Don’t immobilise segment
Efforts to maintain ventilation are important (12-20BPM). Probably breathing faster than normal, so need oxygen as respiration not effective.
Traditionally, the patient has been turned onto the effected side for transport. (If you put on their good side the chest on the good side can’t expand properly)
Consider analgesia
Time critical transport
What is a pneumothorax
Air in the potential space between the two pleura. The pocket of air puts pressure on the lung, causing it to collapse.
Tension pneumothorax - more air than space so increase in pressure.
Spontaneous pneumothorax
Build up of air in pleural cavity
Small spontaneous rupture in the lung
More common on young men
No trauma that caused this, just spontaneous.
Open pneumothorax
Sucking chest wound
To be class as this it needs to have an open wound associated with it.
Draws air into a lung during inspiration and draws air into pleural cavity. So air coming in through two holes.
Forces air out a lung during expiration and pleural cavity. But not all air will be able to come back out the wound.
How to help open pneumothorax
Russel chest seal. Cover penetrating chest wound allowing air to escape from pleural cavity without being drawn back in.
Nightingale dressing - para only application for chest injury
What is a tension pneumothorax
Life threatening and time critical
Any pneumothorax can lead to a tension pneumothorax
It occurs when air gets into the pleural cavity but cannot escape.
How to fix a tension pneumothorax
Needle thoracocentesis (chest decompression paramedic only skill)
Don’t really expect it to work
Signs and symptoms of a tension pneumothorax
Hyperinflation on the one side (looks bigger than the other)
Reduced or no movement on that side
Pale
Clammy skin
This might not be an injury in isolation
Struggling to breathe/ respiratory distress
Tachycardia and tachypnoea.
Reducing SPO2.
Hyper resonance on affected side (higher sound) and reduced air sounds.
Distended neck veins
Tracheal deviation (air pressure is now so great it is pushing everything over)t
