nursing management of unconscious patient

It is this nucleus that sends inhibiting messages back to the thalamic nuclei using the neurotransmitter γ-aminobutyric acid (GABA). The RF is a network of neurones within the brain stem (Waugh & Grant 2001) that connect with the spinal cord, cerebellum, thalamus and hypothalamus. A gentle shake of the patient’s shoulder may be sufficient to elicit a response. Irrigate the eye with sterile prescribed solution to remove 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of irreversible Permanent Vegetative State (PVS) should not be considered or confirmed (and therefore treatment not be withdrawn) until the patient has been insentient for 12 months’. It will help in partially emptying the bladder. Although the patient has sleep/waking cycles, the higher centres of the brain are destroyed. In order to function, the RAS must be stimulated by input signals from a wide range of sources. In cycle A, the RAS excites the cerebral cortex and the cortex in turn re-excites the RAS. Confused = scores 4. 13) must also be taken into account. Side railing on both sides are helpful to protect the hourly position changing to relieve pressure on pressure areas. When an individual is in a deep sleep, the RAS is in a dormant state. The frequency of recording will be based on the patient’s clinical condition. The need to assess conscious level may arise at any time, in any ward, in any hospital. Provide frequent update information on patient condition. The feedback mechanism, showing two feedback cycles passing through the RAS. Cleanse the mouth with the prescribed solution every 2nd Management of severe malaria: a practical handbook second. A definitive airway should be in place before traveling to radiology. Score = 1. 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. In observation role; Critique colleague performance. Score = 5. discharge and advice about long-term problems and support services. Oxygen therapy should be commenced early and the patient’s oxygen saturation levels monitored to reduce the risk of hypoxia. Although the patient has sleep/waking cycles, the higher centres of the brain are destroyed. Management of the Unconscious Patient. Two main parts have been identified (Guyton & Hall 2000): the mesencephalon and the thalamus. Activation of the muscle stimulates proprioceptors to transmit sensory impulses upward to re-excite the RAS. Obeys commands. However, almost any type of sensory signal can immediately activate the RAS and waken the individual, for example when daylight is detected by the retina of the eye, impulses are sent to the suprachiasmatic nucleus of the hypothalamus, activating sympathetic nerve fibres that will inhibit the secretion of melatonin in the pineal gland. hourly and apply emollients to prevent parotitis.

The verbal response may also be compromised by the presence of an endotracheal or tracheostomy tube. This article aims to assist nurses … How to care for a patient's eyes in critical care settings Nurs Stand. Figure 28.7 Applying a central painful stimulus. Monitors patient’s vital signs. (refer practicals), Administer prescribed intravenous fluids with 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. The nurse needs to be aware if the patient has any hearing deficits because if their eyes are closed, this will affect the initial response. Nail bed pressure is contraindicated as it will cause excessive bruising. Keep the skin dry, clean and free of moisture to prevent bed The patient is unable to produce any verbal response despite prolonged and repeated stimulation. The RF is involved in the coordination of skeletal muscle activity, including voluntary movement, posture and balance, as well as automatic and reflex activities that link with the limbic system. accurate output. Early diagnosis and treatment with medication, and environmental changes such as reducing noise or sensory input may help to alleviate some of the symptoms. Management of-unconscious-patient 1. Abnormal flexion. Score = 2. 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. The documentation made recommendations for best practice including: When monitoring the patient’s conscious level, the functional state of the brain is assessed as a whole. Figure 28.5 Applying a peripheral painful stimulus: fingertip stimulation. Formulate a differential diagnosis. Some neuro-rehabilitation units use a structured technique for assessing various sensory aspects of communication, movement awareness and wakefulness, known as SMART (sensory modality assessment and rehabilitation technique – www.smart-therapy.org.uk/), to enable clinicians to make a more accurate diagnosis of patients they suspect may be in PVS. The legs are generally straight, with the feet pointing outwards. Physiologically, the brain stem is functioning but the cerebral cortex is not, and patients can survive for several years requiring full-time nursing care. (Changes from baseline are most important), Cleanse the mouth with the prescribed solution every 2, Pharyngitis: Etiology, Symptoms, Diagnosis, Management, Urinary tract infection: Symptoms, Diagnosis, Management, Complication, Acute renal failure : Symptoms, Diagnosis, Management, Convulsion: Causes, Classification, Symptoms, Diagnosis, Complication, Child health nursing- Principles and practices: Introduction, Preventive paediatric Nursing Nutrition in children, Antenatal Preparation and Physiology of lactation. To speech = scores 3. In cycle B, impulses are sent down the spinal cord to activate skeletal muscles. 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. How to go through your neuro ICU patient assessment. suctioning, nasogastric tube or urinary catheter. The clinical condition of unconsciousness is one of complex physiology. The term stupor describes a state whereby the patient is quiet and tends not to move, except in response to vigorous and repeated noxious stimuli (Hickey 2003). Any signs of shock are addressed with fluids, blood, and/or vasopressors. This is very different from spontaneous eye opening and should be recorded as ‘none’. Asses the patient' s level of consciousness by Glasgow coma Applying a central painful stimulus. The best response for each of the three aspects is recorded as a numerical score. Score = 4. 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. Copyright © 2018-2021 BrainKart.com; All Rights Reserved. A person may become unconscious due to oxygen deprivation, shock, central nervous system depressants such as alcohol and drugs, or injury. This assesses the patient’s best motor response. D. Abnormal flexion. This indicates more severe dysfunction of the brain and is a poor prognostic sign. It is difficult to classify levels of consciousness exactly, but this is a useful guide to help to describe various levels. Turn the patient every 2 hours or maintain in a rotating bed if condition allows preventing skin breakdown. Review the contributory causes of altered consciousness shown in Figure 28.3 and consider the underlying mechanism for each of them. Nov. 21, 2020. This is called the ‘arousal reaction’ and is the mechanism by which sensory stimuli wake us from deep sleep (Guyton & Hall 2000). Loosen the garments to allow free movements of the chest and abdomen. The importance of maintaining such an equilibrium is beyond dispute, but die difficulty of understanding what unconsciousness is becomes a contributory factor towards inhibiting the nurse from extending the same totality of care she would offer the conscious patient, to one who is unconscious. It is concerned with the arousal of the brain in sleep and wakefulness (Marieb 2004). This feature is not available right now. Perineal care, vaginal douch, catheter care to be provided. b. maintenance of fluid & Nursing care plan wikipedia. 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). The pattern and rate of respiration is directly affected by increasing brain injury that may produce an ataxic irregular or Cheyne–Stokes respiratory pattern characterised by periods of tachypnoea interspersed with periods of apnoea. The first page of the PDF of this article appears above. This initiates a cycle that causes continued intense excitation of both regions. 1999 Jul;92(7):353-5. However, the patient is able to control vertical eye movements and blinking and may be able to use these movements to develop a simple communication system. Nursing group presentation. Two main parts have been identified (, The mesencephalic area is composed of grey matter and lies in the upper pons and midbrain of the brain stem. E. Extending to pain. poor concentration or short-term memory problems, may only become apparent when a patient returns home. The unconscious patient. 2nd year uts. Pamela Mountjoy SRN, RMN, Barbara Wythe SRN, SCM, Nursing Care of the Unconscious Patient, 1970, Williams and Wilkins Co., Baltimore, 89 Recognition of airway obstruction ASK the patient how they are. 2. A second feedback cycle that stimulates proprioceptors in skeletal muscles is also shown in. Interruption of awareness of oneself and one's surroundings, lack of the ability to notice or respond to stimuli in the environment. 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. 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). This assesses the area of the brain associated with receptive and expressive speech. Alright, now that you’ve gone through some basic tips, let’s go through a systematic way to approach assessing an unconscious neuro patient. In order to appreciate the importance of altered states of consciousness, a basic understanding of the physiology of consciousness is required. Activation of the muscle stimulates proprioceptors to transmit sensory impulses upward to re-excite the RAS. 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. Blog. 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). 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. 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. Consciousness results when the RAS, in turn, stimulates the cerebral cortex. By Donna, Gill, Sharon and Catherine. 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. If the patient has incontinence of urine - provide bedpans Physiologically, the brain stem is functioning but the cerebral cortex is not, and patients can survive for several years requiring full-time nursing care. and vitamins. Clean the ear with swab and dry carefully especially behind incontinency retention and constipation, report to the physician. The nurse plays a pivotal role working with the multidisciplinary team to plan, implement and evaluate specific treatment regimens, whilst providing emotional support and reassurance to the patient and their relatives. 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. The damaged cortex is unable to interpret the incoming sensory impulses and therefore cannot transmit them to other areas for appropriate action. 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. Motor responses. These can cause emotional distress for both the patient and family, particularly if they go unheeded and help is not provided. Score = 3. It must be necessary to hold the patients jaw forward or Chris is an Intensivist and ECMO specialist at the Alfred ICU in Melbourne. In the case of eye opening, the best response would score a 4, the best verbal response would score a 5 and the best motor responses would score a 6. Even if you're aware of unconscious bias, your reaction to your patient sets the tone for his or her care. Author Max Geraghty is senior staff nurse, Intensive Care Unit, North Middlesex University … What is meant by a head injury patient? Unconsciousness is a condition in which there is depression of cerebral function ranging from stupor to coma. E. Extending to pain. 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. Mid-sagittal section of the brain, showing the reticular activating system and related structures. However, the patient is able to control vertical eye movements and blinking and may be able to use these movements to develop a simple communication system. ETA 3 minutes." The individual is awake, alert and aware of their personal identity and of the events occurring in their surroundings. How unconscious bias can discriminate against patients and affect their care Published by British Medical Journal, 03 November 2020 Article raises awareness of unconscious bias in healthcare, i.e. This chapter has presented a physiologic approach to the differential diagnosis and the emergency management of the stuporous and comatose patient. Figure 28.2 The feedback mechanism, showing two feedback cycles passing through the RAS. Signs and symptoms may include: Reduction in awareness reflects generalised brain dysfunction, as seen in systemic and metabolic disorders (see Figure 28.3). 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. The verbal response may contain indistinct mumbling but no intelligible words. help of pillow or sand bags to prevent foot drop. Following painful stimulation, the patient responds by rigid extension, i.e. None =scores 1 . of personal hygiene and care of pressure areas including prevention of foot Published on 26/03/2015 by admin. Mental functions progressively decline with global deterioration of memory, thought processes, motor performance, emotional responsiveness and social behaviour. deafness or paralysis) or if the patient is receiving muscle relaxants. 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. of cerebral function ranging from stupor to coma. Opening of the eyes implies arousal, but it must be remembered that this does not necessarily mean that the patient is aware of their surroundings. Patients can have a varying degree of recumbency from a patient with osteoarthritis to a dog in a coma. (refer practicals). Understanding what may trigger your reactions … tube feeding. how personal assumptions which we may not be aware of can lead to erroneous clinical decisions. Lesions in this area can cause excessive sleepiness or even coma (, The cerebrum regulates incoming information by a positive feedback mechanism (Guyton & Hall 2000). practicals), 7 or less generally indicates coma Following the application of a central painful stimulus, either the trapezius squeeze or supraorbital ridge pressure, the patient responds by flexing their arm normally by bending their elbow and weakly withdrawing their hand; no attempt to localise towards the source of the pain is made. Lesions in this area can cause excessive sleepiness or even coma (Fitzgerald 1996). Only gold members can continue reading. 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. The unconscious patient is completely dependent on the nurse to manage all their activities of daily living and to monitor their vital functions. As the condition develops, speech and communication becomes difficult and behaviour becomes increasingly inappropriate until control of basic and vital processes is completely disorganised. More questions related to this article: What do you understand by a head injury? Impaired states of consciousness can be categorised as acute or chronic. Your body language, focused attention, or level of care can be directly impacted by your feelings toward the patient. None. Palpate the abdomen for distension   Ascultate bowel sounds. B. Localising to pain. The reticular nucleus, which receives impulses from the RF, surrounds the front and sides of the thalamus. If the patient is constipated, a glycerine suppository or Filed under Emergency … The patient has the ability to follow instructions, for example, ‘put out your tongue’, ‘lift up your arms’, ‘show me your thumb’. Even during normal sleep, an individual can be roused by external stimuli, in comparison to the person in a coma. 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). Inappropriate words = scores 3. This initiates a cycle that causes continued intense excitation of both regions. Figure 28.6 Motor responses. Orientated = scores 5. Maintenance Unconscious clients have increased metabolic needs (immunodeficiency, proteins wasting, lung tissue, catabolism, negative nitrogen state). 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. (refer practicals). None = scores 1. Patients will present with a range of symptoms including: Delirium is very distressing for the patient and their relatives who may witness their altered behaviour. 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. 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. Sleep is induced by a hormone called melatonin which is synthesised from serotonin in the pineal gland. There is ongoing debate, both in the UK and other countries, about the moral, ethical and legal issues surrounding the care and treatment of these individuals and the dilemma posed by some patients to ‘the right to die’ and withdrawal of treatment has received considerable professional, public and political attention over recent years (Porter 2005) (see www.ethics-network.org.uk). Nursing 1st year 2. If the patient still fails to open their eyes, a painful stimulus must be used. 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. 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). Hearing can often be the last sense to be lost and the first one to come back before they are able to respond. Apply back care every 4th hourly and 2nd Posner JB, Saper CB, Schiff N, Plum F. Plum and Posner’s Diagnosis of Stupor and Coma 4e Oxford university Press, 2009. 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. If the patient is observed for any sign of urinary Consciousness cannot be measured directly but can be estimated by observing behaviour in response to stimuli. Pressure is gradually increased for a maximum of 15 seconds. 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… the ears. A score of 15 indicates that the patient is alert, orientated and able to obey commands; a score of 8 or less is generally considered to indicate that the patient is in a coma. The patient will moan or groan in response to painful stimulation. In the early stage, subtle changes may occur in the patient’s behaviour. 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. 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. Factors that impair consciousness may also cause respiratory changes. Applying a peripheral painful stimulus: fingertip stimulation. Self care deficit Attending to the hygiene needs of the unconscious patient should never become ritualistic, and despite the patient's perceived lack of awareness, dignity should not be compromised. Nursing Management : a.Maintenance of effective airway : - An adequate airway must be maintained at all times. Neurological examination of the unconscious patient. Normal conscious behaviour is dependent upon the functioning of the higher cerebral hemispheres and an intact reticular activating system (see below). However, if the eyelids are drawn back, the eyes may remain open. 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). Signals from different areas in the thalamus initiate selective activity in the cortex protecting the higher centres from sensory overload (Marieb 2004). This is a typical prehospital call for a drowned patient, and it results in the entire staff gearing up for the incoming patient. (BS) Developed by Therithal info, Chennai. Walker MC, O’Brien MD. They may exhibit signs of hyper-excitability and irritability, alternating with drowsiness, progressing to confusion and increased levels of disorientation. For further information about PVS and locked-in syndrome, see Randall (1997), Smith (1997) and Royal College of Physicians (2003). 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. enema is advised according to doctor' s prescription. Common causes of altered level of consciousness are illustrated in Figure 28.3 (see, Cognitive disabilities, e.g. Some neuro-rehabilitation units use a structured technique for assessing various sensory aspects of communication, movement awareness and wakefulness, known as SMART (sensory modality assessment and rehabilitation technique –, There is ongoing debate, both in the UK and other countries, about the moral, ethical and legal issues surrounding the care and treatment of these individuals and the dilemma posed by some patients to ‘the right to die’ and withdrawal of treatment has received considerable professional, public and political attention over recent years (Porter 2005) (see. LISTEN and FEEL for … 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). 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. What is visual communication and why it matters; Nov. 20, 2020. Minor disturbance such as irritability can easily go undetected and comments from a relative such as ‘she does not seem to recognise me today’ may denote a subtle change in behaviour that requires further investigation. Both require a thorough assessment to determine the level of nursing care that they will need. Poisonous drugs (stomach wash, refer The bed linen must be kept wrinkle free and dry. required for life. Initiate appropriate initial management. The patient is unable to speak and is sometimes unable to breathe spontaneously, the latter requiring mechanical ventilation and respiratory support. These disorders interfere with the integrity of the RAS, affecting the patient’s arousal response. Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail, Care of unconscious patient: Causes, Diagnosis, Management. 5. It is important to remember that the patient is cognitively aware, even if they appear to be mentally and physically inert. Nurses have a difficult time because they approach the patient directly. This is termed a ‘positive feedback response’. D. Abnormal flexion. airway by falling back. Variations in the motor response may occur during the assessment. This is a PDF-only article. The unconscious patient is a medical emergency which can challenge the diagnostic and management skills of any clinician. A systematic and logical approach is necessary to make the correct diagnosis; the broad diagnostic categories being neurological, metabolic, diffuse physiological dysfunction and functional. They are: This condition is caused by a generalised and progressive loss of cortical tissue in the brain. Coma may be defined as no eye opening on stimulation, The responses described below are shown in Figure 28.6. the specialised auditory and visual tracts (see Ch. B. Trapezius pinch. Maintaining patent airway. A. Supraorbital ridge pressure. (Changes from baseline are most important).
