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. 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). Author Max Geraghty is senior staff nurse, Intensive Care Unit, North Middlesex University … Unknown down time. Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail, Care of unconscious patient: Causes, Diagnosis, Management. The damaged cortex is unable to interpret the incoming sensory impulses and therefore cannot transmit them to other areas for appropriate action. As the condition develops, speech and communication becomes difficult and behaviour becomes increasingly inappropriate until control of basic and vital processes is completely disorganised. The responses described below are shown in Figure 28.6. patient. Oxygen therapy should be commenced early and the patient’s oxygen saturation levels monitored to reduce the risk of hypoxia. This initiates a cycle that causes continued intense excitation of both regions. Nurses are advocates of a patient. CHAPTER 28 Nursing the unconscious patient. Provide frequent update information on patient condition. Keep the skin dry, clean and free of moisture to prevent bed Obtain a complete patient history including the … It consists of caring for people and their families. 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. Only gold members can continue reading. They may exhibit signs of hyper-excitability and irritability, alternating with drowsiness, progressing to confusion and increased levels of disorientation. (Changes from baseline are most important). This is indicated on the patient’s chart as ‘T’. 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. A neurological assessment includes the recording of additional measurements as follows: A rising blood pressure (elevated systolic pressure), widening of the pulse pressures and a slowing pulse (see Ch. The patient is unable to speak and is sometimes unable to breathe spontaneously, the latter requiring mechanical ventilation and respiratory support. 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). This is a typical prehospital call for a drowned patient, and it results in the entire staff gearing up for the incoming patient. Reply Delete It is important to remember that the patient is cognitively aware, even if they appear to be mentally and physically inert. Obeys commands. The lowest response for each of the three parameters is a score of 1. This feature is not available right now. 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). Congenital deficits of the eye or previous enucleation (see Ch. Protect the airway of the unconscious patient. It necessary insert oral airway for easy breathing. Palpate the abdomen for distension   Ascultate bowel sounds. An adequate airway must be maintained at all times. Management of-unconscious-patient 1. Published on 26/03/2015 by admin. 9). If the patient still fails to open their eyes, a painful stimulus must be used. Range of motion exercises at least 4 times daily. Coma may be defined as no eye opening on stimulation, ETA 3 minutes." Explain the nursing management of head injury patient. Asymmetrical responses are significant, indicating that a focal neurological deficit is present, but overall brain function is more accurately reflected by the level of best response on the better side (see Limb movement, below). A definitive airway should be in place before traveling to radiology. A. Supraorbital ridge pressure. A. Obeys commands (‘lift up your arms’). Impaired, reduced or absent consciousness implies the presence of brain dysfunction and demands urgent medical attention. 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.

If the patient is constipated, a glycerine suppository or Variations in the motor response may occur during the assessment. 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. 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. 3. Maintaining patent airway. Irrigate the eye with sterile prescribed solution to remove Be advised we are en route with a 23-month-old child found submerged in a swimming pool. A. Supraorbital ridge pressure. Normal conscious behaviour is dependent upon the functioning of the higher cerebral hemispheres and an intact reticular activating system (see below). Consciousness results when the RAS, in turn, stimulates the cerebral cortex. Consciousness cannot be measured directly but can be estimated by observing behaviour in response to stimuli. Develop an interpersonal relationship with the family. of cerebral function ranging from stupor to coma. Mental functions progressively decline with global deterioration of memory, thought processes, motor performance, emotional responsiveness and social behaviour. Early diagnosis and treatment with medication, and environmental changes such as reducing noise or sensory input may help to alleviate some of the symptoms. Initiate appropriate initial management. By Donna, Gill, Sharon and Catherine. Your body language, focused attention, or level of care can be directly impacted by your feelings toward the patient. 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. over the bladder region. The RAS is also affected by signals from the cerebral cortex, i.e. B. Trapezius pinch. 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. Figure 28.1 Mid-sagittal section of the brain, showing the reticular activating system and related structures. The individual is awake, alert and aware of their personal identity and of the events occurring in their surroundings. 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). 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. sore. During the first few hours of coma, neurologic assessment is to be done as often as every 15 minutes. The reticular formation (RF) and the reticular activating system (RAS) (Figure 28.1) are responsible for collating and transmitting motor and sensory activities and controlling sleep/waking cycles and consciousness. In order to appreciate the importance of altered states of consciousness, a basic understanding of the physiology of consciousness is required. 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. Follow these steps for your next neuro assessment. Spontaneously = scores 4. Score = 2. Both require a thorough assessment to determine the level of nursing care that they will need. 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’. 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. Unconsciousness is a condition in which there is depression of cerebral function ranging from stupor to coma. Side railing on both sides are helpful to protect the Patient obtunded, assisting respirations. C. Flexing to pain. This assesses the integrity of the RAS in the brain stem and is observed and recorded using the following categories. Monitor Intake and output chart accurately and record. nursing assignment help nursing help nursing assignment. Pressure is gradually increased for a maximum of 15 seconds. 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). Nursing care plan wikipedia. practicals). 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. of personal hygiene and care of pressure areas including prevention of foot J R Soc Med. Copyright © 2018-2021 BrainKart.com; All Rights Reserved. In order to function, the RAS must be stimulated by input signals from a wide range of sources. The verbal response may contain indistinct mumbling but no intelligible words. The patient who is in a deep coma with flaccid eye muscles will show no response to stimulation. deafness or paralysis) or if the patient is receiving muscle relaxants. If the painful stimulus does not elicit any response from the patient this indicates a deep depression of the arousal system and the patient is recorded as having no eye opening. Any new or acute change from the patient’s normal baseline behaviour must be reported and documented. 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). Formulate a differential diagnosis. This article discusses the nursing management of patients who are unconscious and examines the priorities of patient care. The legs are generally straight, with the feet pointing outwards. Common causes of altered level of consciousness are illustrated in Figure 28.3 (see, Cognitive disabilities, e.g. hourly and apply emollients to prevent parotitis. This is a PDF-only article. 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. If the patient has retention of urine, apply gentle pressure Lesions in this area can cause excessive sleepiness or even coma (, The cerebrum regulates incoming information by a positive feedback mechanism (Guyton & Hall 2000). This assesses the area of the brain associated with receptive and expressive speech. 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. 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. Score = 6. The cerebrum regulates incoming information by a positive feedback mechanism (Guyton & Hall 2000). Physiologically, the brain stem is functioning but the cerebral cortex is not, and patients can survive for several years requiring full-time nursing care. 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. In cycle A, the RAS excites the cerebral cortex and the cortex in turn re-excites the RAS. The reticular nucleus, which receives impulses from the RF, surrounds the front and sides of the thalamus. 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 approach is based on the belief that after a history and a general physical and neurologic examination, the informed physician can, with reasonable confidence, place the patient into one of four major groups of illnesses that cause coma. The patient is unable to speak and is sometimes unable to breathe spontaneously, the latter requiring mechanical ventilation and respiratory support. Involving the family in self care needs. 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. Reassess after intervention. Nutrition may be supplied by intravenous fluids or gastric None =scores 1 . the specialised auditory and visual tracts (see Ch. Management of severe malaria: a practical handbook second. Signals from different areas in the thalamus initiate selective activity in the cortex protecting the higher centres from sensory overload (Marieb 2004). This is termed a ‘positive feedback response’. This response is only recorded when sufficient painful stimulus has been applied to provoke a response and no detectable movement has been observed. However, if the eyelids are drawn back, the eyes may remain open. It will help in partially emptying the bladder. Patients may be unable to understand the nurse’s questions or commands because they do not understand the language or may have a hearing deficit. Neurological assessment in nursing is a critical skill for a neuro ICU nurse. 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). Nov. 21, 2020. 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 unconscious patient is completely dependent on the nurse to manage all their activities of daily living and to monitor their vital functions. Walker MC, O’Brien MD. suctioning, nasogastric tube or urinary catheter. 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. The mesencephalic area is composed of grey matter and lies in the upper pons and midbrain of the brain stem. b. maintenance of fluid & Common causes of altered level of consciousness are illustrated in Figure 28.3 (see www.headway.org.uk). 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. In cycle A, the RAS excites the cerebral cortex and the cortex in turn re-excites the RAS. Even during normal sleep, an individual can be roused by external stimuli, in comparison to the person in a coma. 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. 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. A second feedback cycle that stimulates proprioceptors in skeletal muscles is also shown in. These can cause emotional distress for both the patient and family, particularly if they go unheeded and help is not provided. It may be necessary to increase the level of the verbal stimulation to gain a reaction. Clean the ear with swab and dry carefully especially behind The patient is unable to produce any verbal response despite prolonged and repeated stimulation. In observation role; Critique colleague performance. 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. They are: This condition is caused by a generalised and progressive loss of cortical tissue in the brain. 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. A. Obeys commands (‘lift up your arms’). 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 has incontinence of urine - provide bedpans It is important to remember that the patient is cognitively aware, even if they appear to be mentally and physically inert. The chronic states of impaired consciousness tend to be irreversible as they are caused by invasive or destructive brain lesions. 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.
