UNCONSCIOUSNESS
UNCONSCIOUSNESS
IT IS AN ABNORMAL STATE RESULTING
FROM DISTURBANCE OF SENSORY
PERCEPTION TO THE EXTENT THAT
THE PATIENT IS NOT AWARE OF WHAT
IS HAPPENING AROUND HIM.
PERIOD MAY BE MOMENTARY OR MAY
LAST FOR MONTH.
LEVELS OF UNCONSCIOUNESS
• EXCITATORY UNCONSCIOUSNESS:
PATIENT DOES NOT RESPOND
COHERENTLY BUT IS EASILY
DISTURBED BY SENSORY STIMULI.
COMMONLY SEEN IN PATIENTS
WHO ARE GOING UNDER
ANESTHESIA.
• SOMNOLENT:
PATIENT IS EXTREMELY
DROWSY AND WILL RESPOND
ONLY OF SPOKEN TO
DIRECTLY AND PERHAPS
TOUCHED.
• STUPOROUS
PATIENT RESPONDS ONLY TO
PAINFUL STIMULI SUCHAS
PRICKING OR PINCHING OF THE
SKIN.
IN DEEP STUPOR PATIENT MAY
RESPOND ONLY TO SUPRAORBITAL
OR SUBSTERNAL PRESSURE.
ETIOLOGY
• STRUCTURAL LESIONS IN BRAIN.
eg; Brain tumor,Cerebral haemorrage.
• METABOLIC DISORDERS.
eg;Infections,Hypoglycemia,Nutritional
deficency.
• PSYCHOGENIC CAUSES.
eg;Hysteria, Catatonia.
• a car accident
• severe blood loss
• a blow to the chest or head
• a drug overdose
• alcohol poisoning
low blood sugar
low blood pressure
syncope, or the loss of consciousness due to lack of blood
flow to the brain
neurologic syncope, or the loss of consciousness caused by
a seizure, stroke, or transient ischemic attack (TIA)
dehydration
problems with the heart’s rhythm
straining
hyperventilating
COMMON CAUSES OF TEMPORARY UNCONSCIOUSNESS INCLUDE:

CLINICALMANIFESTATIONS
Symptoms that may indicate that
unconsciousness is about to occur include:
 sudden inability to respond
 slurred speech
 a rapid heartbeat
 confusion
 dizziness or lightheadedness
DIAGNOSTIC ASSESSMENT
• GLASGOW COMA SCALE.
• COMPUTED TOMOGRAPHY.
• MAGNETIC RESONANCE IMAGING.
• LUMBAR PUNCTURE.
• EEG.
• VENTRICULOGRAPHY.
• ANGIOGRAPHY.
• DRUG LEVEL.
• LFT/RFT
• BLOOD GASES & PH
• SERUM GLUCOSE,CALCIUM,SODIUM ect.

IMMEDIATE
MANAGEMENT
• Maintain i.v line, oxygen inhalation
• Blood sample for RBS
• Control seizures
• Consider i.v glucose, thiamine,
naloxone, flumazenil
NURSINGMANAGEMENT
• Maintenance of an adequateairway.
• Maintenance of circulatoin.
• Moving and position.
• Mouth care.
• Eyecare.
• Foodand fluids.
• Prevention of accidents.

 Potential complications of being unconscious for
a long period of time include coma and brain
damage.
 A person who received CPR while unconscious
may have broken or fractured ribs from the chest
compressions. The doctor will X-ray the chest and
treat any fractures or broken ribs before the
person leaves the hospital.
 Choking can also occur during unconsciousness.
Food or liquid may have blocked the airway.
