Week 10 - Brain Tumours and Abscesses Flashcards
what are 4 types of brain tumours
- primary
- secondary
- benign (encapsulated)
- malignant (invasive)
what is a primary brain tumour
- arises from tissues inside the brain
what is a secondary brain tumour
- results from malignant neoplasm/tumour elsewhere
what are clinical manifestations of brain tumours (7)
- HA (dull)
- S&S of IICP
- seizures
- NV
- cognitive problems
- mood problems
- personality changes
*depend on location of tumour)
what is included in collab care for brain tumour (6)
- meds
- ventricular shunts
- surgery
- radiation (internal, external)
- chemo
- nursing care for IICP
what med if used for brain tumour? what effect does it have
- corticosteroids ex. dexamethsone
- decreases edema surrounding the tumour
what is a ventricular shunt
- drains CSF from ventricles to R atrium or peritoneum
what surgery may be done for brain tumours? (3)
- surgery to debulk or remove mas
- craniotomy
- stereotactic radiosurgery (high dose radiation precisely delivered)
what is a brain abscess
- accumulation of pus within the brain tissue
what can a brain abscess result in?
- local or systemic infection
what are the primary causes of brain abcess (2)
- strep
- staph aureus
ex. ear, tooth, jaw, or sinus infection/surgery
what is used as a diagnostic for brain abscess
- CT scan
what are S&S of brain abscess (8)
- similar to meningitis & encephalitis
- HA
- fever
- nausea
- confusion
- drowsiness
- seizures
- focal symptoms
describe collab care/treatment for brain abscess (3)
- antibiotic therapy long term (>6 weeks)
- surgery to drain or remove abcess
- nursing care for IICP
describe the process of a craniotomy (4)
- remove bone flap
- remove clot, tumor, or fix problem
- establish drain
- re-attach bone flap (later time, not urgent)
