1 Chapter 29 Spinal Cord Injury

2 Objectives Discuss major causes of spinal cord injury
Discuss common spinal cord injuries and their classifications Describe the nursing management of the client with a spinal cord injury.

3 Etiology / Pathology Spinal Cord injury from accidents is a common and increasing cause of serious disability and death. Most people involved with spinal cord injuries are males between 18 and 25 years of age Other causes: autos, motorcycles, surfing, other athletic events, and gunshot wounds

4 Spinal Cord Trauma Complete cord injury:
Total transection of the spinal cord – all voluntary movement below the level of the injury is lost Incomplete injury: partial transection of the spinal cord – some movement remains

5 Diagnostic Tests and Procedures
Neurologic examination Initial evaluation of the spinal cord: injured patient provides the nurse with a baseline assessment of function and problems  Ongoing assessment necessary to monitor the effects of neurologic injury, detect related complications, and determine patient’s need for assistance in activities of daily living Focuses on the motor and sensory systems

6 Diagnostic Tests and Procedures
Imaging studies Radiography Detects vertebral compression, fractures, or problems with alignment Computed tomography (CT) Noninvasive examination of the specific levels of the spinal cord to be visualized, bony vertebrae, and the spinal nerves Magnetic resonance imaging (MRI) Produces precise, clear images of internal structures Myelogram Visualizes the spinal cord and vertebrae

7 Pathophysiology of Spinal Cord Injury

8 Types of Injuries Location Cervical. Thoracic. Or lumbar Open or closed Closed: trauma in which the skin and meningeal covering that surround the spinal cord remain intact Open: damage to the protective skin and meninges Extent of damage to the cord Complete spinal cord injury occurs when the cord has been completely severed, whereas an incomplete injury results from partial cutting of the cord

9 Effects of Spinal Cord Injury
Factors include extent of cut and level of injury Sometimes cannot be fully determined because the symptoms of spinal cord edema may mimic partial or complete transection With incomplete spinal cord injuries some function remains below the level of the injury Specific tracts may be involved, causing particular patterns of neurologic dysfunction

10 Figure 29-6

11 Effects of Spinal Cord Injury
The higher the level of injury, the more encompassing the neurologic dysfunction Quadriplegia High cervical spine injuries; loss of motor and sensory function in all four extremities Paraplegia Injuries at or below T2 may cause paralysis of the lower part of the body

12 Respiratory Impairment
Injuries at or above the level of C5 may result in instant death because the nerves that control respiration are interrupted Cervical injuries below the level of C4 spare the diaphragm but can involve impairment of intercostal and abdominal muscles

13 Spinal Shock An immediate, transient response to injury in which reflex activity below the level of the injury temporarily ceases A period of flaccid paralysis and complete loss of reflexes below the trauma The loss of systemic sympathetic vasomotor tone  vasodilation  hypotension Known as “areflexia” and is temporary Pt. may need respiratory support temporarily The loss of systemic sympathetic vasomotor tone may result in vasodilation, increased venous capacity, and hypotension. DURING THIS TIME THE PATIENT MAY NEED TEMOPROARY RESPIRATORY SUPPORT

14 Autonomic Dysreflexia
Exaggerated response of autonomic nervous system to noxious (painful) stimuli With injury at or above the level of T6 The sympathetic nervous system is stimulated, but an appropriate parasympathetic modulation response cannot be elicited because of the spinal cord injury that separates the two divisions of the autonomic nervous system Hyperreflexia. Increased relex acutions. Also occurs as a result of abnormal cardiovascular tesonse to stimulation of the sympathetic di ision of the autonomic nervous suystem as a result od stimulation of bladder. Laorge intestine, or other visceral organs.

15 Autonomic Dysreflexia
Clinical Signs Severe bradycardia Hypertension (systolic pressure up to 300mmHg) Diaphoresis “Gooseflesh” Flushing Dilated pupils Blurred vision Severe headache Restlessness Nausea Nasal stuffiness Most common causes: DISTENDED BLADDER FECAL IMPACTION Patients begin to recognize these right away. Fecal impaction and bladder distention is a medical emergency to prevent CVA, blindness death

16 Autonomic Dysreflexia
Triggered by various stimuli including a distended bladder, constipation, renal calculi, ejaculation, or uterine contractions, but also may be caused by pressure sores, skin rash, enemas, or even sudden position changes Treatment: p.712 Box 14-4 – unless contraindicated, raise head of bed immediately to reduce blood pressure; then treat cause of the reaction

17 Spasticity Muscle spasms may be incapacitating for these patients, hampering efforts at rehabilitation

18 Impaired Sensory and Motor Function
Impaired motor function can affect the patient’s mobility and self-care and thus result in complications from immobility Loss of sensation puts patient at risk for skin breakdown and other injuries because pressure and pain are not perceived

19 Impaired Bladder Function
During spinal shock, all bladder and bowel function ceases Once spinal shock resolves, reflex activity returns

20 Impaired Bowel Function
Most spinal cord–injured patients can maintain bowel function because the large bowel musculature has its own neural center that responds to distention by the fecal mass

21 Impaired Temperature Regulations
May lose these regulatory mechanisms and be unable to adapt to temperature extremes

22 Impaired Sexual Function
Spinal levels S2, S3, and S4 control sexual function, so injury at or above these levels results in sexual dysfunction Ability to achieve erection and ejaculation is variable

23 Impaired Skin Integrity
Because immobile patient can’t change positions, skin in sacral area and across bony prominences may break down Loss of tone results in vasodilation and pooling of blood in the periphery; impedes perfusion of the skin; and encourages the development of pressure sores

24 Altered Self-Concept and Body Image
French and Phillips (1991) describe the effects of spinal cord injury on body image as occurring in four phases: impact, retreat, acknowledgment, and reconstruction

25 Medical Treatment in the Acute Phase

26 Saving the Patient’s Life: Establish Airway
Conventional head-tilt–chin-lift: inappropriate - increases risk of cord damage Risk of additional damage is especially high with cervical injury Neck flexion, even that caused by a pillow or other support, must be avoided Jaw-thrust method of opening the airway is preferred for these patients

27 Saving the Patient’s Life: Establish Airway
Once airway is open, administer 100% oxygen by mask and manual resuscitator Endotracheal or tracheostomy tube is placed to allow direct access to the airway and facilitate optimal oxygenation Any injury that compromises ventilation must be treated immediately

28 Preventing Further Cord Injury
Traction Immobilization with skeletal traction manages cervical spinal cord injuries acutely Gardner-Wells tongs Secured just above the ears; doesn’t actually penetrate skull Crutchfield tongs Applied directly to the skull just behind the hairline Halo vest: immobilizes and aligns cervical vertebrae; placed when surgery is done to internally stabilize fractures and relieve the compression of nerve roots

29 Inserted into skull the hyperextend head and neck

31 Preventing Further Cord Injury
Special beds and cushions Kinetic bed, such as the Roto-Rest bed, continually rotates the patient from side to side Overlay air mattresses: floatation devices placed on standard hospital beds Air-fluidized and floatation beds may be used after the spine has been stabilized Wedge-Stryker frame: canvas and metal frame bed that may be used to help turn the patient Types of cushions include those inflated with air, floatation devices, and gel pads

32 Figure 29-9

33 Preventing Further Cord Injury
Drug therapy Methylprednisolone Reduces the damage to the cellular membrane Administered within the first 8 hours of injury Completely paralyzed patients often regain about 20% of function Partially paralyzed have regained up to 75% of function

34 Preserving Cord Function
Early surgical intervention to repair cord damage Cord compression by bony fragments, compound vertebral fractures, and gunshot and stab wounds Surgery within the first 24 hours is most desirable Laminectomy Involves removing all or part of the posterior arch of the vertebra Spinal fusion If multiple vertebrae are involved Placing a piece of donor bone into area between the involved vertebrae

35 Assessment Monitor the patient’s level of consciousness, vital signs, respiratory status, motor and sensory function, and intake and output Objective: complete neuro assessment; observations

36 Health History Present illness
Event that brought the patient to the hospital Specific injuries incurred in the incident Describe pain and other symptoms in detail

37 Past Medical History Other accidents or injuries and chronic illnesses such as diabetes, hypertension, heart disease, cancer, or seizure disorder Previous hospitalizations and operations Obstetric history from female patient Identify and record current medications and allergies

38 Family History Routine family history taken but not considered specifically relevant to a diagnosis of spinal cord injury resulting from trauma

39 Interventions Nursing Diagnosis: (r/t, AEB; Nanda approved)
Ineffective Breathing Pattern Risk for Injury and Disturbed Sensory Perception Risk for Autonomic Dysreflexia Risk for Disuse Syndrome Bowel Incontinence Impaired Urinary Elimination

40 Interventions Nursing Diagnoses cont. Risk for Infection
Ineffective Thermoregulation Feeding/Dressing/Grooming Self-Care Deficit Sexual Dysfunction Ineffective Coping Ineffective Therapeutic Regimen Management

41 Rehabilitation Activities that assist individual to achieve highest possible level of self-care and independence Well-organized interdisciplinary team that can address all aspects of function Physician, nurse, physical therapist, occupational therapist, speech therapist, dietitian, social worker, psychologist, and counselor Patient and family must be emotionally and physically prepared to make adjustments

42 Rehabilitation Team helps the patient accomplish activities of daily living and self-care and addresses successful adjustment to social integration and gainful employment in the workplace Although this phase of treatment may take more than a year, patient, family, and rehabilitation team can take pride in the realization that a life can once again be productive and happy

43 Brain Abscess AIDS

44 Brain Abscess An accumulation of pus within the brain tissue
Can result from local or systemic infection Primary cause: direct extension from ear, tooth, mastoid, or sinus infection Streptococci and staphylococci are primary infective organisms

45 Brain Abscess Clinical manifestations:
Similar to those of meningitis and encephalitis Headache, fever, s/sx ICP (drowsiness, confusion, seizure) Focal symptoms in local area of abscess E.g. visual field defects with temporal lobe abscess

46 Brain Abscess Medical Treatment Nursing interventions Antibiotics
Encapsulated abscesses may need to be surgically removed Nursing interventions Similar to those for ICP, meningitis If surgical removal involved, nsg. Interventions similar to those for intracranial tumors


48 AIDS > 80% of advanced HIV disease patients have neurological symptoms Clinical Manifestations Dementia: subacute encephalitis Global Cognitive Dysfunction: generalized impairment of intellect, awareness, and judgment Opportunistic infections: meningitis, CMV, toxoplasmosis, herpes simplex, and primary malignant lymphoma the CNS

49 AIDS Diagnostic Tests Medical Management Serologic studies CSF CT, MRI
Administration of medication: antiviral, antifungal, antibiotics Radiation Dehydration/shock: fluid volume expanders Seizures: anticonvulsants

50 AIDS Nursing Interventions
Safety: related to disorientation, seizures, visual impairment Pain relief measures Depression: provide support; maintain nonjudgmental attitude Feeding: increased assistance; poss. TF Incontinent care

51 Other Disorders of the Neurological System

52 Disturbances in Muscle Tone and Motor Function
Etiology/pathophysiology Damage to the nervous system causes serious problems in mobility E.g. pt. with cerebral palsy

53 Disturbances in Muscle Tone and Motor Function
Clinical manifestations/assessment Flaccid: muscle is weak, soft, flabby; lacks normal muscle tone Hyperreflexic muscle tone: increased reflex actions Clumsiness or incoordination Abnormal gait

54 Disturbances in Muscle Tone and Motor Function
Assessment of patients with motor problems: Subjective Data: patients understand of the problem and possible causes; initial onset of sx., any improvement; presence of clumsiness or incoordination; abnormal sensations Objective Data: coordination, muscle strength, muscle tone, presence of muscle atrophy; response to checking of reflexes; abnormal gait

55 Disturbances in Muscle Tone and Motor Function
Diagnostic Tests: EMG Medical management/nursing interventions Muscle relaxants to treat spasticity E.g. Baclofen; Valium Protect from falls Assess skin integrity Positioning Prefeeding and feeding exercises; Sit up and tuck chin when eating Encourage patient to assist with ADLs Emotional support

56 Disturbances in Muscle Tone and Motor Function
Nursing Interventions Safety needs. Protection from falls Use of siderails and chair support Watch for signs of unilateral neglect Eye care on the paralyzed side Skin Assessment: pressure relief aids Turning and positioning schedule Inspect skin daily and prn

57 Disturbances in Muscle Tone and Motor Function
Nursing Interventions cont. Activity needs: care and positioning of affected extremities Risk for contractures if unattended to ROM – active, passive OT, PT may provide splints and braces Prevent foot drop and wrist drop Appropriate positioning

58 Disturbances in Muscle Tone and Motor Function
Nursing Interventions cont. Nutritional Needs: patience and persistence while giving food and fluids to patients with hemiplegia Aspiration Precautions Checking cheeks for accumulated food Special utensils/assistive devices may be used ADLs – promote maximum independence OT, Nursing, PT

59 Disturbances in Muscle Tone and Motor Function
Nursing Interventions cont. Psychological Adjustments: To body changes Changes in abilities Fears of rejection Self-esteem issues Referrals, support, networking

60 Disturbed Sensory and Perceptual Function
Etiology/pathophysiology The presence of a lesion anywhere along the sensory system pathway alters the transmission or perception of sensory information The parietal cortex of the brain is of major importance in interpretation and sensation Any alteration lessens the patient’s ability to be completely protected from inadvertent injury

61 Disturbed Sensory and Perceptual Function
Etiology/ pathophysiology cont. One specific loss: Proprioception (the ability to know the position of the body and its parts without looking at it) Other loss: Agnosia (total or partial loss of the ability to recognize familiar objects or people).

62 Disturbed Sensory and Perceptual Function
Assessment: Subjective Data: pts. Understanding of the sensory disturbance; measures that relieve symptoms; presence of symptoms that occur with the sensory problem Objective Data: note pt. ability to perform useful movement or recognize familiar objects

63 Disturbed Sensory and Perceptual Function
Medical Management: per alterations in muscle tone and motor function Nursing Interventions: Most Important: teaching the patient protective measures! Learning to inspect parts of his/her body that have no feeling Protect sensitive parts of the body that are at risk: i.e. avoid bedding rubbing over toes
