The Glasgow Coma Scale [1] (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury. The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These three behaviours make up the three elements of the scale: eye, verbal, and motor.
It forms one part of a number of neurological assessments, including the first aid based AVPU scale and the more medically based Glasgow Coma Scale. The objective of pain stimulus is to assess the level of consciousness of the patient by inducing vocalisation in an acceptable, consistent and replicable manner, and to this end, there are a ...
The most commonly used tool for measuring LOC objectively is the Glasgow Coma Scale (GCS). It has come into almost universal use for assessing people with brain injury, [2] or an altered level of consciousness. Verbal, motor, and eye-opening responses to stimuli are measured, scored, and added into a final score on a scale of 3–15, with a ...
The experience of pain is individualistic and can be suppressed by stress or exacerbated by anticipation. Simple activation of a nociceptor does not always lead to perceived pain, because the latter also depends on the frequency of the action potentials, integration of pre- and postsynaptic signals, and influences from higher or central processes.
In the first level, the brain responsiveness lessens, normal reflexes are lost, the patient no longer responds to pain and cannot hear. The Rancho Los Amigos Scale is a complex scale that has eight separate levels, and is often used in the first few weeks or months of coma while the patient is under closer observation, and when shifts between ...
Marginal nucleus of the spinal cord are the only unsuppressible pain signals. The parabrachial area integrates taste and pain info, then relays it. Parabrachial checks if the pain is being received in normal temperatures and if the gustatory system is active; if both are so the pain is assumed to be due to poison.
The Paediatric Glasgow Coma Scale (British English) or the Pediatric Glasgow Coma Score (American English) or simply PGCS is the equivalent of the Glasgow Coma Scale (GCS) used to assess the level of consciousness of child patients.
Disorders of consciousness present a variety of ethical concerns. Most obvious is the lack of consent in any treatment decisions. Patients in PVS or MCS are not able to decide for the possibility of withdrawal of life-support. It is also a general question whether they should receive life-sustaining therapy and, if so, for what duration.
