4 oncological and degenerative neurological disorders Flashcards
ONCOLOGICAL DISORDERS OF THE
BRAIN
Primary brain tumours
Secondary tumours
Primary brain tumours
begin in the brain tissue.
Types of primary brain tumours
Gliomas Meningiomas Acoustic neuromas Pineocytoma Pituary adenomas Angiomas
GLIOMAS
Type of tumour that starts in the glial cells of the brain or the spine.
BRAIN TUMOURS
CLINICAL MANIFESTATIONS
Raised intracranial pressure Headache Vomiting Visual disturbance Hemiparesis Seizures Mental status changes
BRAIN TUMOURS
ASSESSMENT AND DIAGNOSTIC FINDINGS
CT scan MRI PET scan EEG Biopsy Lumbar puncture
BRAIN TUMOURS
MANAGEMENT
Dependant on the type, location, severity and accessibility of the tumour
Medical management
Surgical management
Medical management
Chemotherapy- destroys cancer cells
Radiation- decreases the incidence of recurrence
Brachytherapy- surgical implantation of radiation sourcesto deliver
high doses at a short distance
Corticosteroids- before or after treatment to reduce cerebral oedema
and promote recovery
Surgical management
Remove or destroy the entire tumour
NURSING MANAGEMENT
Neurological exam
Monitoring vital signs
Monitoring ICP
Reorientation
Patient function: self-care ability, movement, walking, speech, vision, dealing
with seizures
Symptoms that may cause distress to the patient: pain, respiratory
symptoms, bowel and bladder function, sleep, skin integrity, fluid balance
and temperature regulation
Nutritional status and dietary history
Family coping and family process
BRAIN TUMOURS
POST OP MANAGEMENT
Reducing cerebral oedema Relieving pain Seizure prevention ICP Monitoring, EVD Airway management, gas exchange Respiratory status Oxygenation, etCO2 monitoring BSL GCS, LOC, pupillary and motor responses Temperature Bone flap obs, monitoring for bleeding Managing fluid and electrolyte disturbance
SPINAL CORD TUMOURS types
Intramedullary
Extramedullary
Intramedullary
within the cord
Extramedullary
Outside the dural membrane
SPINAL CORD TUMOURS symptoms
pain, weakness and loss of motor function, loss
of reflexes, loss of sensation
