Etiology of head trauma
• Falls
• Traffic accidents
• Sport
• Crime, war, …
• Head injury can be associated with:– Alcohol intoxication (masks severity of injury)– Spinal cord injury

![Page 9: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/9.jpg)
First aid
• Keep the person lying down with the head and shoulders slightly elevated
• Don't move the person unless necessary • Avoid moving the person's neck. • Stop any bleeding from wounded soft tissues • Watch for changes in breathing and alertness
– if the person shows no signs of circulation (breathing, coughing or movement), begin CPR

Soft tissues injury
![Page 11: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/11.jpg)
Soft tissues injury
• usually severe bleeding– can result in haemorrhagic shock– bleeding from nose or mouth can result in
chocking
• don't apply direct pressure to the wound if you suspect a skull fracture
![Page 12: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/12.jpg)
Injury of the eye
• penetrating injury – do not remove the foreign body
• cover both eyes until definitive treatment– explanation: movenents of the healthy eye would
worsen the damage of the injured eye
• caustics – rinse the eye well (several minutes under running water)
![Page 13: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/13.jpg)
Unconsciousness• serious sign, usually requires in-hospital
treatment …• … except common fainting
– usually in dehydrated young women – decreased circulating volume
– self-limiting disease – in horizontal position the brain perfusion is being restored rapidly
– leg raise can expedite the recovery– if the unconsciousness persists, call ambulance
![Page 14: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/14.jpg)
Management of unconscious patient
• check the responsivenessAre you OK?
– any response – call for ambulance, check vital signs regularly– no response – continue according A-B-C, start CPR if necessary
![Page 15: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/15.jpg)
Etiology of unconsciousness
• cardiac arrest– A-B-C …
• trauma– head injury, but also…– hypotension in e.g. haemorrhagic shock
• stroke – ischemic or haemorrhagic
![Page 16: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/16.jpg)
Etiology of unconsciousness
• metabolic disorders– history of diabetes? – possible hypo-/
hyperglycemic coma– hyperglycemic coma – aceton smell in breath
• Kussmaul´s breathing – rapid deep breathing
• infections– fever– meningitis – typically petechias (red dots on
skin)
![Page 17: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/17.jpg)
Etiology of unconsciousness
• intoxication– check for characteristic smell in patient´s
breath (e.g. alcohol)– suicide – check for empty drug bottles or
blisters, suicide note– do not induce vomiting in unconscious
patients – risk of aspiration
• hypothermia
![Page 18: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/18.jpg)
Seizures - symptomatology• alteration or absence of consciousness • lip smacking • tonic – clonic convulsions of the entire body or a
body part (1/2 of face, unilateral extremities, …)– involuntary muscle contractions followed by relaxation
• tongue biting due to contraction of jaw muscle • difficulty of breathing • increased secretion of saliva from the mouth
![Page 19: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/19.jpg)
Seizures - symptomatology
• after the seizure:– dizziness, desorientation– with gradual restoration of neurological
functions
![Page 20: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/20.jpg)
Seizures - treatment
• Do not leave the person having the seizure
• Protect the patient from any kind of injury• Do not attempt to open the mouth and put
anything in the mouth – choking hazard – injury of the rescurer
• Turn the patient to his/her side and allow any fluid to come out of the mouth
![Page 21: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/21.jpg)
Seizures - treatment
• Do not attempt to give anything to drink or eat while the person is having a seizure
• Seizures usually last for a short period of time (1-2 minutes)
• If a seizure lasts longer than about five minutes, you should call an ambulance immediately
![Page 22: Head injuries, unconsciousness, seizures MUDr. Martin Kolář, Dept. of Anesthesiology and CCM, FNKV.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649eda5503460f94be9781/html5/thumbnails/22.jpg)
Febrile seizures
• usually in pre-school children• tonic-clonic convulsions of the whole body,
lasting for several minutes• associated to infections with high fever, can be
the first sign of infection• occur during the febrile peak• usually not dangerous, not a sign of epilepsy or
any other serious disease• warning: seizures in children without fever or
infection
