Head Injury

  1. 1. Head Injuries Sarah Sharpe
  2. 2. Head Injury <ul><li>A head injury is any trauma resulting in injury to the scalp, skull or brain. </li></ul><ul><li>A head injury is particularly dangerous as, at first the injury may appear only minor however major internal injuries have occurred. </li></ul><ul><li>A victim with a suspected head injury should be monitored for a number of days after the incident </li></ul><ul><li>There are five main types of head injuries: </li></ul><ul><li>Lacerations </li></ul><ul><li>Concussion </li></ul><ul><li>Contusions </li></ul><ul><li>Haemorrhage </li></ul><ul><li>Compression </li></ul><ul><li>Skull Fracture </li></ul>
  3. 3. What are Lacerations <ul><li>A laceration is a tear in the </li></ul><ul><li>skin as a result of an injury. </li></ul><ul><li>In the case of visible bones </li></ul><ul><li>or tendons, or excessive </li></ul><ul><li>bleeding or pain, the casualty should be seen to by a doctor </li></ul>
  4. 4. Symptoms of Lacerations <ul><li>Bleeding </li></ul><ul><li>Pain </li></ul><ul><li>Numbness </li></ul><ul><li>Swelling of Injured </li></ul><ul><li>Skin </li></ul>
  5. 5. Treating Lacerations <ul><li>Conduct Primary Survey (DRABC) </li></ul><ul><li>If symptoms appear serious, an ambulance should be called immediately </li></ul><ul><li>Place a dry, sterile dressing onto wound and apply direct pressure. If skull fracture is suspected, minimise pressure. </li></ul><ul><li>If injury has resulted in an attached flap of skin </li></ul><ul><li>(avulsion), using clean water gently flush the </li></ul><ul><li>area, fold flap back over laceration and apply </li></ul><ul><li>dressing with pressure </li></ul><ul><li>Use a roller gauze to secure dressings to the </li></ul><ul><li>head. Do not remove dressings </li></ul><ul><li>Casualty should be monitored for the next couple of days </li></ul>
  6. 6. What is a concussion? <ul><li>A concussion is a temporary change in the way the brain works when it is suddenly moved or jarred, it occurs when the brain suddenly shifts inside the skull and knocks against the skulls bony surface. </li></ul><ul><li>Concussions can last from a few moments, to an unconscious state for over 3 minutes. </li></ul>
  7. 7. Symptoms of a Concussion <ul><li>Amnesia, short term memory loss </li></ul><ul><li>Nausea, vomiting </li></ul><ul><li>Headache </li></ul><ul><li>Blurred Vision </li></ul><ul><li>Confusion </li></ul><ul><li>Ringing in Ears </li></ul><ul><li>Neck Pain </li></ul><ul><li>Dizziness </li></ul><ul><li>Unconsciousness </li></ul><ul><li>Irritability </li></ul><ul><li>Convulsions </li></ul>
  8. 8. Treating a Concussion <ul><li>Conduct Primary Survey (DRABC) </li></ul><ul><li>Determine the severity or ‘grade’ of the concussion. </li></ul><ul><ul><li>Grade 1 – conscious, symptoms last under 15 minutes </li></ul></ul><ul><ul><li>Grade 2 – conscious, symptoms last over 15 minutes </li></ul></ul><ul><ul><li>Grade 3 - unconscious </li></ul></ul>Call an ambulance immediately, lay casualty down with head and shoulders slightly raised, try to keep them awake and talking. If casualty falls unconscious and is not breathing, commence CPR and monitor vital signs Seek professional medical assistance, lay the casualty down with the head and shoulders slightly raised. Try to keep casualty awake and talking Allow casualty to rest, however continually monitor in case their condition changes. Lay casualty down with their head and shoulders slightly raised Grade 3 Grade 2 Grade 1
  9. 9. What is a Cerebral Contusion <ul><li>A contusion is a bruise to the brain tissue which occurs when a number of small blood vessels leak into brain tissue. </li></ul><ul><li>Contusions occur </li></ul><ul><li>when the brain </li></ul><ul><li>strikes a ridge in </li></ul><ul><li>the skull, when the </li></ul><ul><li>head moves </li></ul><ul><li>suddenly or hits a solid object with great force. </li></ul>
  10. 10. Symptoms of a Contusion <ul><li>Severe Headache </li></ul><ul><li>Dizziness </li></ul><ul><li>Nausea / Vomiting </li></ul><ul><li>Dilated Pupil </li></ul><ul><li>Weakness of limbs </li></ul><ul><li>Restless, irritable </li></ul><ul><li>Memory Loss </li></ul><ul><li>Confusion </li></ul><ul><li>Drowsiness </li></ul><ul><li>Unconsciousness </li></ul>
  11. 11. Treating a Contusion <ul><li>Conduct Primary Survey (DRABC) </li></ul><ul><li>Seek medical assistance, if symptoms indicate severe head trauma, call ambulance immediately </li></ul><ul><li>Monitor casualty’s level of </li></ul><ul><li>consciousness </li></ul><ul><li>Encourage the casualty to </li></ul><ul><li>stay awake and talk, </li></ul><ul><li>reassure them </li></ul><ul><li>If casualty falls unconscious </li></ul><ul><li>and breathing ceases, commence </li></ul><ul><li>CPR until further help arrives </li></ul>Bilateral Cerebral Contusions
  12. 12. What is a Haemorrhage <ul><li>A brain or subarachnoid haemorrhage occurs when blood leaks out of the blood vessels and onto the surface of the brain. The blood then damages the brain tissue which, along with the blood loss, can cause serious and potentially life threatening brain damage </li></ul>
  13. 13. Symptoms of a Haemorrhage <ul><li>Sudden and Severe headache </li></ul><ul><li>Nausea / vomiting </li></ul><ul><li>Unconsciousness </li></ul><ul><li>Seizure </li></ul><ul><li>Paralysis </li></ul>Preserved brain with haemorrhage
  14. 14. Treating a Haemorrhage <ul><li>Conduct primary survey (DRABC) </li></ul><ul><li>Call an ambulance immediately </li></ul><ul><li>Monitor level of consciousness </li></ul><ul><li>If casualty falls unconscious, commence CPR and continue until further help arrives </li></ul><ul><li>If casualty has a seizure, clear them of any dangers and position them on the ground in a comfortable position and wait for seizure to end. Once ended, roll casualty into recovery position </li></ul><ul><li>Monitor Vital signs until ambulance arrives </li></ul>
  15. 15. What is a Cerebral Compression <ul><li>A cerebral compression involves a build up of pressure on the brain and can be life threatening, most often requiring surgery. Cerebral compression occurs when there is an accumulation of blood within the skull or injured brain tissue swells </li></ul>
  16. 16. Symptoms of a cerebral compression <ul><li>Recent head injury </li></ul><ul><li>Headache </li></ul><ul><li>Noisy, slow breathing </li></ul><ul><li>Slow pulse </li></ul><ul><li>Unequal pupil size </li></ul><ul><li>Weakness of paralysis down one side of body </li></ul><ul><li>High temperature </li></ul><ul><li>Drowsiness </li></ul><ul><li>Change in behaviour </li></ul><ul><li>Disorientation </li></ul><ul><li>Unconsciousness </li></ul>
  17. 17. Treating a cerebral compression <ul><li>Conduct Primary Survey (DRABC) </li></ul><ul><li>Call for an ambulance </li></ul><ul><li>If conscious, rest casualty in comfortable position, reassure them and monitor vital signs until help arrives </li></ul><ul><li>If unconscious and not breathing, commence CPR and continue until help arrives. If breathing, ensure airway is open. </li></ul>
  18. 18. What is a Skull Fracture <ul><li>A skull fracture occurs after a head injury and can be life threatening as the fractured bone may cause damage to the brain. </li></ul>
  19. 19. Symptoms of a Skull Fracture <ul><li>Wound of Bruise on head </li></ul><ul><li>Depression on scalp </li></ul><ul><li>Altered level of response </li></ul><ul><li>Distortion of face </li></ul><ul><li>Blood in the eye </li></ul><ul><li>Clear fluid discharge from nose or ear </li></ul><ul><li>Bruising around eyes </li></ul><ul><li>Bruising or swelling behind an ear </li></ul>
  20. 20. Treating a Skull Fracture <ul><li>Conduct Primary Survey (DRABC) </li></ul><ul><li>Call an ambulance </li></ul><ul><li>If conscious, allow casualty to lie down, stabilise head and neck, control any bleeding by applying dressing with pressure, in case of discharge cover ear but do not plug, monitor vital signs </li></ul><ul><li>If unconscious and not breathing, commence CPR and continue until further help arrives. If breathing ensure airway remains open. Monitor vital signs </li></ul>
