It is dependent upon relatively intact functional areas within the cerebral hemispheres that interact with each other as well as with the RAS (Box 28.2). Only the best response from the arms is recorded as leg responses to pain are less consistent and may be confused with a simple spinal reflex. Even if you're aware of unconscious bias, your reaction to your patient sets the tone for his or her care. The RAS is a physiological component of the RF and the neurones which radiate via the thalamus and hypothalamus to the cerebral cortex and ocular motor nuclei. Consciousness results when the RAS, in turn, stimulates the cerebral cortex. Nursing Management : a.Maintenance of effective airway : - An adequate airway must be maintained at all times. A second feedback cycle that stimulates proprioceptors in skeletal muscles is also shown in Figure 28.2. Vegetative state (VS) is a term used to describe a condition that may occur following a severe brain injury, where there is extensive damage to the cerebral cortex. Draw blood for baseline electrolytes. The National Institute for Health and Clinical Excellence (NICE) developed clinical guidelines for ‘Head injury: triage, assessment, investigation and early management of head injury in infants, children and adults’ (2003), revised 2005. Repeat the patient’s blood glucose level after 1 hour. how personal assumptions which we may not be aware of can lead to erroneous clinical decisions. What is meant by a head injury patient? discharge and debris. For unconscious patients and patients unable to swallow administer dextrose 50% 50ml bolus per IV as prescribed. Therefore, it is the best response that should be scored; for example, if the patient localises to pain on the left side but flexes to pain on the right, the localising response is recorded. It is concerned with the arousal of the brain in sleep and wakefulness (Marieb 2004). Review the contributory causes of altered consciousness shown in Figure 28.3 and consider the underlying mechanism for each of them. Follow these steps for your next neuro assessment. Signs of deterioration in a patient’s level of consciousness are usually the first indications of further impending brain damage. the RAS may first stimulate the cerebral cortex, and the cortical areas responding to reason and emotion may ‘modify’ the RAS, either positively or negatively, according to the ‘decision’ of the cerebral cortex. nursing assignment help nursing help nursing assignment. Patients with normal pressure hydrocephalus may be helped by insertion of a ventricular shunt (Wilson & Islam 2004, Vegetative state (VS) is a term used to describe a condition that may occur following a severe brain injury, where there is extensive damage to the cerebral cortex. Understanding what may trigger your reactions … The unconscious patient is a medical emergency which can challenge the diagnostic and management skills of any clinician. sore. Figure 28.5 Applying a peripheral painful stimulus: fingertip stimulation. Consciousness results when the RAS, in turn, stimulates the cerebral cortex. Rationale and key points Eye care is an important aspect of the nursing management of patients who are critically ill. All patients in acute care settings with absent or compromised eye defence mechanisms are at risk of eye complications and ocular surface disease. Alright, now that you’ve gone through some basic tips, let’s go through a systematic way to approach assessing an unconscious neuro patient. No response may indicate a compromised airway or unconscious patient LOOK for symmetrical chest and abdominal movements. B. Trapezius pinch. Any new or acute change from the patient’s normal baseline behaviour must be reported and documented. Loosen the garments to allow free movements of the chest and abdomen. Monitors patient’s vital signs. 2. The unconscious patient. Confused = scores 4. Score = 4. The patient is unable to speak and is sometimes unable to breathe spontaneously, the latter requiring mechanical ventilation and respiratory support. Injury to, or disease of, the cerebral hemispheres may cause diffuse damage that can inhibit or block the signals from the RAS, depressing the level of consciousness. Impaired states of consciousness can be categorised as acute or chronic. D. Abnormal flexion. Nurse Awards; Nursing Careers and Job Fairs ... Nurse Researcher; Nursing Children and Young People; Nursing Management; Nursing Older People; Nursing Standard; Primary Health Care; Learning Portfolio. In observation role; Critique colleague performance. Unconscious patients are nursed in a variety of clinical settings and therefore it is necessary for all nurses to assess, plan and implement the nursing care of this vulnerable patient group. Despite our strong ethical and moral commitment to others, our biases have a significant impact on nursing practice and the nation's health. In cycle A, the RAS excites the cerebral cortex and the cortex in turn re-excites the RAS. Range of motion exercises at least 4 times daily. Following painful stimulation, the patient responds by rigid extension, i.e. Score = 5. Consciousness cannot be measured directly but can be estimated by observing behaviour in response to stimuli. Incomprehensible sounds = scores 2. None =scores 1 . The patient is unable to speak and is sometimes unable to breathe spontaneously, the latter requiring mechanical ventilation and respiratory support. Fingernails and toenails also need to be assessed Chronic illnesses, such as diabetes needs more attention Minimum two nurses should bathe an unconscious patient as turning the patient may block the airway… To pain = scores 2. The patient will moan or groan in response to painful stimulation. These can cause emotional distress for both the patient and family, particularly if they go unheeded and help is not provided. Prolonged loss of consciousness (coma, defined as a Glasgow Coma Score of 8 or less) is seen commonly: (1) following head injury, (2) after an overdose of sedating drugs, and (3) in the situation of ‘nontraumatic coma’, where there are many possible diagnoses, but the most common are postanoxic, postischaemic, systemic infection, and metabolic derangement, e.g. A. Obeys commands (‘lift up your arms’). Maintenance Unconscious patients are nursed in a variety of clinical settings and therefore it is necessary for all nurses to assess, plan and implement the nursing care of this vulnerable patient … The response is recorded as ‘localising to pain’ if the patient moves their arm across the midline, to the level of the chin, in an attempt to locate the source of the pain (Figure 28.6b). Reply Delete Chris Nickson . In 1974, Teasdale and Jennett developed the Glasgow Coma Scale (GCS), a process used throughout the UK and worldwide as part of the neurological assessment and ongoing observation of the patient (see Figure 28.4). D. Abnormal flexion. When applying a painful stimulus, it is important to explain to the patient and their relatives what you are about to do and why you are doing it, otherwise they may feel that unnecessary trauma is being inflicted. Factors that impair consciousness may also cause respiratory changes. CHAPTER 28 Nursing the unconscious patient. This feature is not available right now. This is indicated on the patient’s chart as ‘T’. Please try again later. deafness or paralysis) or if the patient is receiving muscle relaxants. Nursing 1st year 2. There is no international definition of levels of consciousness but, for assessment purposes, differing states of consciousness can be considered on a continuum between full consciousness and deep coma (Hickey 2003) (see, Impaired states of consciousness can be categorised as acute or chronic. Figure 28.3 Common causes of unconsciousness. The Glasgow Coma Scale (GCS) (Teasdale 1975) is widely used as an assessment tool and helps to reduce subjectivity during assessment of conscious level (see p. 741). Mental functions progressively decline with global deterioration of memory, thought processes, motor performance, emotional responsiveness and social behaviour. The legs are generally straight, with the feet pointing outwards. An adequate airway must be maintained at all times. None = scores 1. Always assume that an unconscious patient is able to hear and understand what you say, particularly if you need to discuss sensitive issues with their relatives. The patient who is unconscious from cerebral catastrophe must depend upon others to detect or anticipate his needs and to institute the appropriate measures to assure his recovery if the pathological insult can be overcome. Localises to pain. Obeys commands. It is important to remember that the patient is cognitively aware, even if they appear to be mentally and physically inert. Gratitude in the workplace: How gratitude can improve your well-being and relationships This occurs when there is damage to the pons in the brain stem, resulting from cerebral vascular disease or trauma, paralysing voluntary muscles without interfering with consciousness and cognitive functions. In cycle B, impulses are sent down the spinal cord to activate skeletal muscles. 9), known as ‘Cushing’s response’, is a very late sign of raised intracranial pressure (ICP) and there may have been other signs such as subtle alterations in behaviour or fluctuating level of consciousness which could have indicated a deterioration in neurological status. Alzheimer’s disease is the most prevalent type of progressive dementia but there are numerous other causes. The response usually includes spastic hand and wrist movements, with an inward rotation of the shoulders and forearms. Spontaneously = scores 4. Coma may be defined as no eye opening on stimulation, It is this nucleus that sends inhibiting messages back to the thalamic nuclei using the neurotransmitter γ-aminobutyric acid (GABA). After the rapid assessment and management of immediate life threats, the next step is to ensure the patient is adequately resuscitated before the inevitable trip to the CT scanner. Nurses have a difficult time because they approach the patient directly. nurse play and important role in the care of unconscious (comtosed) patient to prevent p otential complications respiratory eg;distress, pneumonia,a spiration,p ressure ulcer.this achived by: 1. Figure 28.1 Mid-sagittal section of the brain, showing the reticular activating system and related structures. Neurological examination of the unconscious patient. C. Flexing to pain. secretions or foreign bodies) and using airway adjuncts to maintain airway patency before assessing the rate, depth, rhythm and characteristics of breathing. place the patient in the lateral position to prevent the tongue obstructing Deep coma, the opposite of consciousness, is diagnosed when the patient is unrousable and unresponsive to external stimuli; there are varied states of altered consciousness in between the two extremes (, Anatomical and physiological basis for consciousness. Motor responses. The nurse must be able to assess and observe the patient accurately so that appropriate intervention can be instituted if the level of consciousness deteriorates. Compendium …more CCC. In cycle B, impulses are sent down the spinal cord to activate skeletal muscles. High-quality nursing care is crucial if the patient is to relearn to perceive self and others, to communicate, to control their body and environment and to become independent. suctioning, nasogastric tube or urinary catheter. Nurses are advocates of a patient. Apply back care every 4th hourly and 2nd If the patient still fails to open their eyes, a painful stimulus must be used. What is head trauma? It necessary insert oral airway for easy breathing. When an individual is in a deep sleep, the RAS is in a dormant state. The chronic states of impaired consciousness tend to be irreversible as they are caused by invasive or destructive brain lesions. This occurs when there is damage to the pons in the brain stem, resulting from cerebral vascular disease or trauma, paralysing voluntary muscles without interfering with consciousness and cognitive functions. However, if the eyelids are drawn back, the eyes may remain open. For example, a patient who has aphasia caused by a stroke may appear awake and alert; however, their inability to understand or to use language may decrease their full awareness of self and their environment. The content of consciousness refers to the sum of cognitive and affective mental functions. Unconscious clients have increased metabolic needs (immunodeficiency, proteins wasting, lung tissue, catabolism, negative nitrogen state). This article discusses the nursing management of patients who are unconscious and examines the priorities of patient care. The patient is able to produce phrases or sentences but the conversation is rambling and inappropriate to the questions being asked. Figure 28.6 Motor responses. (refer practicals), Administer prescribed intravenous fluids with Electrolytes High-quality nursing care is crucial if the patient is to relearn to perceive self and others, to communicate, to control their body and environment and to become independent. The patient has the ability to follow instructions, for example, ‘put out your tongue’, ‘lift up your arms’, ‘show me your thumb’. 7 or less generally indicates coma Interruption of awareness of oneself and one's surroundings, lack of the ability to notice or respond to stimuli in the environment. of cerebral function ranging from stupor to coma. These can cause emotional distress for both the patient and family, particularly if they go unheeded and help is not provided. Management of severe malaria: a practical handbook second. It consists of caring for people and their families. The individual is awake, alert and aware of their personal identity and of the events occurring in their surroundings. Stimulation produces a diffuse flow of nerve impulses which pass upwards through the thalamus and hypothalamus, radiating out across the cerebral cortex to provoke a general increase in cerebral activity and wakefulness (see Figure 28.1). Neurological assessment in nursing is a critical skill for a neuro ICU nurse. For further information about the use of the neurological observation chart and GCS in practice, see Woodward (1997a-d), NICE (2003), Waterhouse (2005) and Palmer & Knight (2006). Sign In Register Subscribe ; COVID-19 ; Newsroom . It provides a standardised approach to observing and recording adverse changes in the patient’s level of consciousness, so that appropriate action can be taken (National Institute for Health and Clinical Excellence [NICE] 2003) (Box 28.3). The words and phrases make little or no sense and may express obscenities. There are numerous pathways to both mesencephalic and thalamic areas, arising from the sensory, motor and cortical regions of the cerebral cortex, that deal with a range of emotions. Providing the patient has not sustained a cervical fracture, the ‘trapezius pinch’ (Figure 28.7b) is a useful alternative; the trapezius muscle (the large triangular muscle of the neck and thorax) is squeezed between the nurse’s fingers and thumb. Lesions in this area can cause excessive sleepiness or even coma (, The cerebrum regulates incoming information by a positive feedback mechanism (Guyton & Hall 2000). Such localised defects are not generally regarded as a true altered state of consciousness, but this example highlights the difficulties in defining true conscious behaviour. Normal conscious behaviour is dependent upon the functioning of the higher cerebral hemispheres and an intact reticular activating system (see below). In the unconscious patient, airway obstruction may be caused by the soft palate or epiglottis (not by the tongue) when normal muscle tone is reduced (Resuscitation Council UK, 2011). Applying a central painful stimulus. Eye Opening Verbal Response Motor Response GCS cont: The first score provides a base line for future scorings. Provide frequent update information on patient condition. Assessment of Unconscious Clients For the care to be effective, a nurse should perform frequent, systematic and objective assessment on the comatose client. tube feeding. Published on 26/03/2015 by admin. Although the patient has sleep/waking cycles, the higher centres of the brain are destroyed. Congenital deficits of the eye or previous enucleation (see Ch. patient. This is very different from spontaneous eye opening and should be recorded as ‘none’. Even during normal sleep, an individual can be roused by external stimuli, in comparison to the person in a coma. However, it is important to consider each of the three responses (eye opening, verbal response and motor response) separately, taking into consideration any communication difficulties (e.g. The feedback mechanism, showing two feedback cycles passing through the RAS. The patient may be talkative, loud, offensive, suspicious or extremely agitated. Acute states, for example drug or alcohol intoxication, are potentially reversible whereas chronic states tend to be irreversible as they are caused by invasive or destructive brain lesions. In order to appreciate the importance of altered states of consciousness, a basic understanding of the physiology of consciousness is required. Therefore, Common causes of altered level of consciousness are illustrated in Figure 28.3 (see www.headway.org.uk). Patients are assessed as orientated in person, place and time if they can state their name, where they are and what the year and month are. The cerebrum regulates incoming information by a positive feedback mechanism (Guyton & Hall 2000). Protect the airway of the unconscious patient. It is concerned with the arousal of the brain in sleep and wakefulness (Marieb 2004). J R Soc Med. None. over the bladder region. Pressure is applied to the lateral inner aspect of the second or third finger using a pen or pencil, for a maximum of 15 seconds (Figure 28.5). More questions related to this article: What do you understand by a head injury? absence of comprehensible speech, a failure to obey commands. Unknown down time. What is visual communication and why it matters; Nov. 20, 2020. Deterioration or improvement will depend on a number of factors such as the mechanism, extent and site of injury, age, previous medical history and length of coma. Unconscious: 1. For further information about the use of the neurological observation chart and GCS in practice, see Woodward (1997a-, Nursing patients with musculoskeletal disorders, Nursing patients with disorders of the breast and reproductive systems, Nursing patients with respiratory disorders, Nursing patients who need palliative care, Alexanders Nursing Practice Hospital and Home. observe the patient' s condition and prevent any complications. - Initiate TPN, if the client cannot tolerate Ryle’s tube feeds (excessive vomiting, regurgitation, decreased peristalsis, absent bowel movement). enema is advised according to doctor' s prescription. Oxygen therapy should be commenced early and the patient’s oxygen saturation levels monitored to reduce the risk of hypoxia. The primary care team plays a major role in supporting patients following acquired brain injury, facilitating referral to specialist agencies (see. The British Medical Association (1996) recommends ‘that the diagnosis of irreversible Permanent Vegetative State (PVS) should not be considered or confirmed (and therefore treatment not be withdrawn) until the patient has been insentient for 12 months’. They may exhibit signs of hyper-excitability and irritability, alternating with drowsiness, progressing to confusion and increased levels of disorientation. Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail, Care of unconscious patient: Causes, Diagnosis, Management. During the course of the day, the patient may display a localising response to other sources of irritation, e.g. Nursing the unconscious patient. By Donna, Gill, Sharon and Catherine. The patient offers monosyllabic words, usually in response to physical stimulation. Formulate a differential diagnosis. Develop an interpersonal relationship with the family. In the early stage, subtle changes may occur in the patient’s behaviour. Patients with normal pressure hydrocephalus may be helped by insertion of a ventricular shunt (Wilson & Islam 2004, Dalvi 2010; see also Life NPH in Useful websites, p. 756). Hickey (2003) defines consciousness simply as ‘a state of general awareness of oneself and the environment’ and includes the ability to orientate towards new stimuli. scale. It is important for the nurse to observe the ABCD approach to assessment, ensuring the patient has a clear airway, removing any obstructions (e.g. Martin (1994) suggests that nurses who are expert in the care of head-injured patients can identify cues which indicate behavioural, cognitive, motor and sensory changes even in mild brain dysfunction. Although dementia is an irreversible condition, new drug therapies such as donepezil (Aricept®) are being used successfully to delay onset of the disease. Avoid asking them to state the day or the date as they are not easily remembered, especially after a period of time in hospital. Although the patient has sleep/waking cycles, the higher centres of the brain are destroyed. This is called the ‘arousal reaction’ and is the mechanism by which sensory stimuli wake us from deep sleep (Guyton & Hall 2000). 13) must also be taken into account. 9). It must be necessary to hold the patients jaw forward or place the patient in the lateral position to prevent the tongue obstructing airway by falling back. Deep coma, the opposite of consciousness, is diagnosed when the patient is unrousable and unresponsive to external stimuli; there are varied states of altered consciousness in between the two extremes (Box 28.1). If the patient is observed for any sign of urinary For further information about PVS and locked-in syndrome, see Randall (1997), The need to assess conscious level may arise at any time, in any ward, in any hospital.
