Brain Tumor review
Question | Answer |
---|---|
There are two types of brain tumors | Supratentorial (from above the tentorium cerebelli), Infratentorial ( from below the tentorium cerebelli) |
Primary tumors | Arise in the brain (CNS), rarely metastasize and most common brain tumors are gliomas. Gliomas develop in the glial cells which make up the soft, spongy tissue that supports the nerve cells in the brain. Five year survival rate is 33% |
Secondary tumors | tumors that come form other places - Common sources, lung, breast kidney, GI tract |
Supratentorial | severe headache upon awakening, seizures, paralysis, changing in mentation, changes in personality, optic disc swelling (double vision) |
Infratentorial | hearing loss, nystagmus, autonomic nervous system, ataxia |
S/S of Brain tumor | seizures, headache, vision changes, paralysis, memory loss, language impairment, change in speech/slurred speech, hearing loss, ataxia, drowsiness, depression, confusion, vomiting (usually in am) |
ICP goal is what? | Goal is 15-20 mm Hg |
Decadron (Dexamethasone) | Giving a steroid to decrease cerebral swelling increases risk for: HYPERglycemia, osteoporosis, fluid retention and weight gain. BASICALLy it decreases edema |
Codeine phosphate has been the standard treatment of pain in patients after craniotomy because Morphine | avoided due to its potential to cause respiratory depression and risk of masking pupillary signs |
Positioning post craniotomy | Keep HOB up to 30 degrees, maintain head in neutral position, avoid neck flexion and avoid hip/knee flexion |
