There is no eye opening to loud, clear commands. This is recorded when no response to a painful stimulus is observed. For example, the presence of neurological reflexes is often an excellent sign of possible recovery. (1976) Assessment and prognosis of coma after head injury. http://www.merckmanuals.com/professional/neurologic-disorders/coma-and-impaired-consciousness/overview-of-coma-and-impaired-consciousness. 2.4 As the GCS is an assessment of conscious level, it cannot be determined with accuracy in the patient who is receiving anaesthetic agents; neurological assessment then focuses on pupillary responses. Pupillary response is what the pupils of the eyes do when exposed to light. A patient who awakens from a coma may also develop a so-called locked-in syndrome, being completely conscious but paralyzed and unable to communicate, except through eye blinks. People who are unconscious for a longer time might transition to a persistent vegetative state or brain death. The patient does not respond verbally to verbal or physical stimuli. For the purpose of neurological assessment the size and reaction of the pupils to bright light are recorded. Mayo Clinic is a not-for-profit organization. Spinal reflexes may cause the arms/legs to flex briskly in response to pain and must not be interpreted as a response. A patient is classified as confused when one or more of the above questions are answered incorrectly. are employed to access the underlying cause of the coma. They make no eye, verbal or motor movements spontaneously, or in response to your spoken requests. The GCS is a standardized instrument for assessing the level of consciousness. Metabolic encephalopathy. This Clinical Guideline is intended for use by healthcare professionals within Leeds unless otherwise stated. No response to painful stimuli, except for reflex movements 5. A patient who is localising to pain is allocated a score of 5. A patient with flaccid ocular muscles may lie with his eyes open all the time. 7th ed. A minority of coma … Many types of problems can cause a coma. If the motor response is different on each side, the better response is incorporate within the Glasgow coma scale. All rights reserved. Pupillary reactivity is relatively resistant to metabolic insult and usually is spared in coma from drug intoxication or metabolic causes, even when other brainstem reflexes are absent. Pathways of the pupillary reflex The pathway for pupillary constriction for each eye has an afferent limb taking sensory information to the midbrain, and two … A millimetre scale (as indicated on the neurological observation chart) is used to estimate the size of each pupil. Details about how the affected person lost consciousness, including whether it occurred suddenly or over time 3. No verbal response is allocated a score of 1. During a coma, a person is unresponsive to their environment. Any use of this site constitutes your agreement to the Terms and Conditions and Privacy Policy linked below. The Glasgow coma scale is based on three aspects of a patient's behaviour - eye opening, verbal response and motor response (see Table 1). The parasympathetic nerve fibres of the 3rd cranial nerve (oculomotor nerve) control constriction of the pupil. If a patient has an endotracheal tube or tracheostomy tube in situ, this is recorded as ‘T' on the chart under ‘No Response' and allocated a score of 1. 24: 270-80. recovery, ICU), a GCS must be assessed by both the nurse escorting the patient and the nurse receiving the patient (at the same time) in order to avoid misinterpretation and facilitate continuity of assessment. The signs and symptoms of a coma commonly include: 1. Doctors normally order a series of blood tests and a brain scan to try to determine what's causing the coma so that proper treatment can begin. Neither scale is wrong; however, it is important that actual clinical response is communicated, rather than a number, to enable carers to work out the Glasgow coma score whichever scale is used. Glasgow Coma Scale (GCS) - Best motor response (M). Eye opening to pain is recorded when a patient opens his eyes to a painful stimulus: finger tip pressure and supraorbital ridge pressure are the two most commonly used methods of applying a painful stimulus. Accessed Nov. 6, 2020. This is recorded when the patient carries out the following command: assessing both sides, the patient is asked to grip and let go of the assessor's fingers. A patient who obeys commands is allocated a score of 6. d. Non-reactive pupils may also be caused by local damage. The normal response is a slow deviation of eyes toward the side of cold water, then fast return to midline (nystagmus). This is recorded when words and speech cannot be identified. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic. Flexion is not seen as a purposeful response and may be a reflex action. When light is shone into the eye the pupil should constrict immediately. In practice, the GCS is just one part of the neurological examination, even in unconscious patients. This is recorded when there is no response to a painful stimulus. As such, after gaining stabilization of the patient's airways, breathing and circulation (the basic ABCs) various diagnostic tests, such as physical examinations and imaging tools (CT scan, MRI, etc.) A patient who has a flexion response to pain is allocated a score of 4. Accessed Nov. 8, 2020. When it was described, features of focal dysfunction such as brainstem signs were not incorporated and instead were intended to be assessed separately. These guidelines apply to all adult patients requiring assessment of consciousness using the Glasgow coma scale and pupil responses within The Leeds Teaching Hospitals NHS Trust. This content does not have an Arabic version. Although diagnosis of coma is simple, investigating the underlying cause of onset can be rather challenging. The Leeds Teaching Hospitals NHS Trust has adapted the 15 point scale. When stimulated their eyes do not open, they make no sounds, but their arms flex normally. In the presence of facial fractures or gross eye swelling, pinching the earlobe is more favourable than applying supraorbital ridge pressure. The lens that is the human eye, should respond instantly to a change in light conditions. Coma is from the Greek word komawhich means deep sleep. The Glasgow Coma Scale (GCS) is a scale that allows health professionals to assess conscious level impairment in response to defined stimuli. They are aimed at doctors, registered nurses, student nurses, and allied health professionals involved in the assessment of the Glasgow coma scale and pupil responses. The pupils should constrict immediately and equally bilaterally; after you remove the light, they should immediately dilate back to baseline. Assessment of the pupillary reflex is one of the most useful means of differentiating metabolic from structural causes of coma. a. 2.1 The arms give a wider range of responses and for this reason are always observed using the Glasgow coma scale. You now test their pupil reactivity to light. Mydriasis refers to dilated pupils that do not change in response to changes in light levels. Pupil size and reaction to light are important neurological observations. A score is applied to each category and totalled to give an overall value ranging from 3 to 15. Stupor Glasgow Coma Scale (GCS) - Best eye response (E). "Mayo," "Mayo Clinic," "MayoClinic.org," "Mayo Clinic Healthy Living," and the triple-shield Mayo Clinic logo are trademarks of Mayo Foundation for Medical Education and Research. 2.5 Some drugs may affect pupillary reaction and the effects of any prescribed medication must be considered when assessing the pupils. Figure 4: Extension response to painful stimulus. To be classified as orientated, patients must be able to identify: All three components must be identified correctly for a patient to be classified as orientated. An ovoid pupil may be an indication of intracranial hypertension. The GCS is a standardized instrument for assessing the level of consciousness. Some examples are: Although many people gradually recover from a coma, others enter a vegetative state or die. A patient is classified as using inappropriate words when conversational exchange is absent - there is a tendency to use single words more than sentences. Further, the response elicited by finger tip pressure might also be misinterpreted as a motor response, particularly when the problems associated with ‘localising' and ‘withdrawing' to pain are taken into account. Assessment of conscious level is an essential component of neurological examination and is usually performed together with assessment of pupillary size and reaction, vital signs, and focal neurological signs in the limbs. Figure 2: Normal flexion response to painful stimulus. 2.2 Always record the best arm response. Accessed Nov. 6, 2020. b. His pupils did not respond to light, his eyelids did not blink when his eye was touched with sterile cotton, he did not have a gag or cough reflex in response to tracheal suction, and he did not initiate any breaths on his own—all breathing was provided by the ventilator. Those who show no motor response have a 3% chance of making a good recovery whereas those who show flexion have a better than 15% chance. Other data suggest that prognostication should be delayed until day 3. Coma is a state of prolonged unconsciousness that can be caused by a variety of problems — traumatic head injury, stroke, brain tumor, drug or alcohol intoxication, or even an underlying illness, such as diabetes or an infection. Wiese, M.F. It is a much slower response than ‘Normal flexion' and may be accompanied by spastic wrist flexion (Figure 3). If the pupils shrink in response, then their brain stem is intact. A patient who is using inappropriate words is allocated a score of 3. To standardise practice so that the Glasgow coma scale and pupil responses can be assessed in a consistent manner to minimise misinterpretation. While critics might argue that supraorbital ridge pressure could cause the patient to grimace and keep the eyes closed, finger tip pressure could lead to misinterpretation of the eye opening response due to other complicating factors such as hemiparesis and high spinal cord injury. Assuming the visual pathways to the lateral geniculate body are intact, assessment of the pupillary responses is important in localising the site of coma and separating structural from toxic/metabolic causes, as pupillary responses in the latter are generally intact (fig 4 ). b. Depressed brainstem reflexes, such as pupils not responding to light 3. This can be scored as E1V1M4 using the Glasgow Coma Scale, giving a sum score of 6. Coma . If there is no spontaneous eye opening, this is recorded when a patient opens his eyes to loud, clear commands. Patients in a coma are alive yet unable to perceive or react meaningfully to their external environment. A deterioration of one point in the ‘Motor Response' or one point in the ‘Verbal Response' or an overall deterioration of two points in the GCS is of clinical significance and must be reported to medical staff. © 1998-2020 Mayo Foundation for Medical Education and Research (MFMER). 14, 15 A unilateral, dilated, unreactive pupil … Some neurological signs that doctors look for in coma patients include: Pupillary reactivity. 2 The FOUR (Full Outline of UnResponsiveness) score adds pupil… From: Medical Pharmacology and Therapeutics (Fifth Edition), 2018. Some medications, recreational drugs, and injuries can cause this. A patient who is fully orientated to time, place and person is allocated a score of 5. https://www.ninds.nih.gov/Disorders/All-Disorders/Coma-Information-Page. They are aimed at doctors, registered nurses, student nurses, and allied health professionals involved in the assessment of the Glasgow coma scale and pupil responses. Pupillary Responses. Teasdale G, Jennett B. It is characterised by internal rotation and adduction of the shoulder and flexion of the elbow. The patient is unresponsive to verbal commands and is therefore assessed for response to painful stimuli. The signs and symptoms of a coma commonly include: A coma is a medical emergency. 2.3 Responses must be recorded on the relevant observation chart in black ink. This content does not have an English version. ‘No motor response' is allocated a score of 1. ScopeThese guidelines apply to all adult patients requiring assessment of consciousness using the Glasgow coma scale and pupil responses within The Leeds Teaching Hospitals NHS Trust. GCSEyeRespnsScale. In deep coma there is no response. If the pupil does not react to light: record as '-', c. If the pupil is sluggish in response when compared to the other pupil: record as ‘S'. It is the method favoured by The Leeds Teaching Hospitals NHS Trust and these guidelines have been developed to standardise practice so that the Glasgow coma scale and pupil responses can be assessed in a consistent manner to minimise misinterpretation. Elsevier; 2016. https://www.clinicalkey.com. Marshall LF, Barba D, Toole BM, Bowers SA. J Neurosurg. The Glasgow-Liège score includes pupil response, the oculocephalic reflex, and the oculocardiac reflex. Two years later, its authors introduced a distinction between normal and abnormal flexion, increasing the ‘best motor response' item by one point (Teasdale and Jennett, 1976). In a normal flexion response to pain, no localising to pain is seen. (1974) Assessment of coma and impaired consciousness. a. 1. Depressed brainstem reflexes, such as pupils not responding to light, No responses of limbs, except for reflex movements, No response to painful stimuli, except for reflex movements. National Institute of Neurological Disorders and Stroke. Make a donation. Part 1: The GCS-Pupils score: an extended index of clinical severity. 3 The Innsbruck Coma Scale adds pupil size, pupil response to light, eyeball position and movements, and oral automatisms in a 31-point assessment. A bright light is shone into each eye and the result recorded. If a patient is dysphasic, best verbal response cannot be determined with accuracy. Oculocephalic response. Mayo Clinic Graduate School of Biomedical Sciences, Mayo Clinic School of Continuous Professional Development, Mayo Clinic School of Graduate Medical Education, Book: Mayo Clinic Family Health Book, 5th Edition, Newsletter: Mayo Clinic Health Letter — Digital Edition, FREE book offer – Mayo Clinic Health Letter. Ed. Figure 3: Abnormal Flexion response to painful stimulus. The use of oaths is common. Be prepared to provide information about the affected person, including: 1. This is recorded when in response to a painful stimulus, a patient bends the arms at the elbow (Figure 2). Stupor and coma in adults. The patient is unresponsive and cannot be roused.' This is called the direct light reflex. The Glasgow Coma Scale4. Bradley's Neurology in Clinical Practice. A patient presents with straightening of the elbow joint, adduction and internal rotation of the shoulder and inward rotation and spastic flexion of the wrist (Figure 4). Normal pupils are round and equal in size - average size is 2 to 5 mm in diameter. The person is alive and looks like they are sleeping. When the light is withdrawn from one eye, the opposite pupil should dilate simultaneously. It is important to exclude the fact that a patient is asleep before proceeding to assess eye opening.This is recorded when a patient is observed to be awake with eyes open. A person’s total score on the GCS—a minimum of 3 indicates deep coma, a maximum of 15 indicates full consciousness—indicates his or her level of consciousness after brain trauma. Eye opening to pain is allocated a score of 2. The patient must grip and un-grip to discount a reflex action. In addition to the GCS score, doctors also look at … To assess the patient’s pupils, hold both eyelids open and shine a light into the eyes. Complications can develop during a coma, including pressure sores, urinary tract infections, blood clots in the legs and other problems. 18% of patients with no pupillary response immediately after cardiac arrest have recovered pupillary responses by day 3 Absence of pupillary, corneal and doll’s eyes reflexes, GCS <5 and flexion response or worse Þ severe disability, vegetative state, persistent coma … AHFS Drug Information (2004 Edition) American Society of Health System Pharmacists. Pupillary responses. • Flexion in response to pain (decorticate posturing) 3 points • Extension response in response to pain (decerebrate posturing) 2 points • No response 1 point References Teasdale G, Jennett B. The guidelines focus on the practical aspects of carrying out and interpreting the Glasgow coma scale and pupil responses. The pupil is the opening, which exactly as an automatic camera would do, will increase the dilation (size of the opening) with less light, and decrease the size of the opening with more light. a. A score is applied to each category and then added up to … This was introduced because the significance between flexion and abnormal flexion helped with the prognosis of the patient. Although pupil reaction is not included as part of the GCS, it is often incorporated into the neurological assessment charts used in healthcare facilities in addition to the use of the GCS. Accessed Nov. 6, 2020. To be classified as localising to pain, a patient must move his hand to the point of stimulation, bringing the hand up beyond the chin and across the midline of the body (Figure 1). Simplifying the use of prognostic information in traumatic brain injury. The light reflex is the primary determinant of pupil size, with increased light causing the pupil to constrict and reduce the amount of light that reaches the retina. A sluggish response to light in a previously reacting pupil must be reported at once to medical staff. Pupillary reflex is examined using a light stimulus to one eye, which produces constriction of the ipsilateral pupil (direct response) and contralateral pupil (consensual response), through a network of connections. Stupor and coma. It is a rapid response (likened to withdrawing from touching something hot) and is associated with abduction of the shoulder. Because people in a coma can't express themselves, doctors must rely on physical clues and information provided by families and friends. 2017. Young GB. 2.7 Within the neurosurgical intensive care and high dependency units, a GCS must be assessed at verbal handover/beginning of the shift by both nurses (at the same time) in order to avoid misinterpretation and facilitate continuity. J Neurotrauma. A coma seldom lasts longer than several weeks. It evaluates three aspects of responsiveness: eye opening, motor response, verbal response. Procedure: a painful stimulus is applied to the supraorbital ridge (to stimulate the supraorbital nerve). (2003) British versions and different versions of the Glasgow coma scale: telephone survey. Eye opening to speech is allocated a score of 3. http://www.uptodate.com/contents/search. A recent telephone survey of accident and emergency hospitals pointed out that some hospitals use the older 14 point scale (Wiese, 2003). The withdrawal of the light should produce an immediate and brisk dilatation of the pupil. Introducing the light into one pupil should cause a similar constriction to occur simultaneously in the other pupil. Copyright© Leeds Teaching Hospitals NHS Trust In a coma, if CN III/IV/VI/VIII pathways are intact, the eyes tonically deviate toward the cold stimulus with no fast phase. The Glasgow coma scale is based on three aspects of a patient’s behaviour - eye opening, verbal response and motor response (Table 1). Focal neurological observations are used to localise cerebral disease to a specific area of the brain while evidence of focal abnormalities may or may not co-exist with evidence of diffuse brain function. Within six hours of coma onset those patients who show eye opening have almost a one in five chance of achieving a good recovery whereas those who do not have a one in 10 chance. It may be a transient phenomenon during acute illness or persist in the long term. The following are important points to note when assessing a patient's level of consciousness using the Glasgow coma scale and calculating a Glasgow coma score (GCS). This is recorded as a ‘D' on the chart under ‘No Response' and allocated a score of 1. Any external light source should be eliminated if possible. A patient who has ‘Abnormal flexion' to pain is allocated a score of 3. The oval pupil: Clinical significance and relationship to intracranial hypertension. Coma information page. The Glasgow coma scale developed by Teasdale and Jennett (1974) is the most widely used assessment tool to measure a patient's level of consciousness. Patient Assessment3. Merck Manual Professional Edition. Compression of this nerve will result in fixed, dilated pupils. 2007. Document the response: Is it brisk, sluggish, nonreactive, or fixed? Lancet 1974; 81-84. There is no ‘Normal flexion' to a painful stimulus. No responses of limbs, except for reflex movements 4. The Glasgow Coma Scale provides a clinical index of the ‘overall’ acute impairment of brain function, or so called ‘conscious level’. d. The shape of the pupil should also be assessed. Coma is a pathologic state of unconsciousness from which a person cannot be aroused to make any purposeful responses. These guidelines recommend that eye opening to pain is assessed by applying supraorbital ridge pressure to stimulate the supraorbital nerve, increasing the pressure until a response is obtained. This site complies with the HONcode standard for trustworthy health information: verify here. c. The shape of each pupil should be recorded in the nursing documentation. See our safe care and visitor guidelines, plus trusted coronavirus information. d. A sluggish pupil may be difficult to distinguish from a fixed pupil and may be an early focal sign of an expanding intracranial lesion and increased intracranial pressure. The effects of intravenous atropine sulphate on the pupil are dose related and higher doses further dilate the pupil. The GCS is used to rate the severity of coma, by assessing the patient’s ability in 3 components: Eye opening – observe eye opening; Verbal response – observe content of speech; Motor response … It is important to differentiate between localising to pain and flexion to pain as localising is a purposeful response and an indication of better brain function. If in any doubt, then the patient is asked to raise the eyebrows. 2.9 Although the Glasgow coma scale should be communicated using its individual components, a score from 3 to 15 may be used to summarise the scale. Events leading up to the coma, such as vomiting or headaches 2. Pontine lesions (infarct or hemorrhage) classically involves sudden collapse with coma, pinpoint pupils and a spastic tetraparesis with brisk reflexes. c. Antimuscarinics dilate the pupil. 19.
