Glasgow Coma Scale(GCS)

GLASGOW COMA SCALE:
  • The Glasgow Coma Scale (GCS) is the standard measure used to quantify level of consciousness in head injured patients.
  • Widely used in scoring systems and treatment protocols.
  • Used as a initial assessment tool and for continual re-evaluation of head injured patients
  • Low score in Glasgow coma scale indicates deteriorating brain function
  • The GCS is scored between 3 and 15, 3 being the worst(dead), and 15 ( conscious person)the best.
  • GCS is composed of three parameters :

  1. Best Eye Response (4)
  2. Best Verbal Response (5)
  3. Best Motor Response (6)
A GCS of:
  1. 13 or higher correlates with a mild brain injury
  2. 9 to 12 is a moderate injury
  3. 8 or less a severe brain injury
  • Best Eye Response (4)
  1. No eye opening =>1
  2. Eye opening to pain =>2
  3. Eye opening to verbal command =>3
  4. Eyes open spontaneously =>4

  • Best Motor Response (6)

  1. No motor response =>1
  2. Extension to pain=>2
  3. Flexion to pain=>3
  4. Withdrawal from pain=>4
  5. Localizing pain=>5
  6. Obeys Commands=>6

  • Best Verbal Response (5)
  1. No verbal response =>1
  2. Incomprehensible sounds =>2
  3. Inappropriate words =>3
  4. Confused =>4
  5. Orientated =>5
  • Total GCS=Motor response + Verbal response + Eye opening
  • Interpretation brain injury
  1. Severe <9 br="" style="font-size: 14px;"> Moderate 9-12
  2. Minor 13 and above

  • Note that the phrase 'GCS of 11' is essentially meaningless, and it is important to break the figure down into its components, such as E3V3M5 = GCS 11. 
  • Glasgow coma scale More than 9 excludes coma
PROS:
  • Reliably predicts outcomes for diffuse and focal lesions
CONS:
  • It does not take into account
  • Focal or lateralizing signs
  • Diffuse metabolic processes
  • Intoxication
Exam Question of:
  • Eye opening , Motor response, Verbal response are used for gradation ohttp://www.neetpgtestseries.com/2017/07/hartnup-disease.htmlspan style="color: #38761d;">Glasgow coma scale score for head injury, eye opening seen with painful stimulus, localize pain and inappropriate verbal response is 10
  • Glasgow coma scale is the best prognostic factor in a case of head injury
  • According to the Glasgow Coma Scale (GCS), a verbal score of 1 indicates No response
  • Glasgow Coma Scale score in a conscious person is 15
  • Glasgow coma scale Ranges from 3 – 15
  • Glasgow coma scale are Less than 7 is classified as coma
  • Glasgow coma scale More than 9 excludes coma
  • Mild head injury is having Glasgow comahttp://www.neetpgtestseries.com/2017/07/hartnup-disease.html"color: #38761d;">Low score in Glasgow coma scale indicates deteriorating brain function
  • According to the Glasgow Coma Scale (GCS), a verbal score of 1 indicates No response
  • A person with 'Inappropriate speech' evaluated by the 'Glasgow Coma Scale' will have a verbal score of 3
  • Glasgow coma scale in death is 3
