Q

Medication for delirium?

A

1 Med tx: Cholinesterase inhibitors (donepezil, rivastigmine, galantamine)

#2: Memantine

IV e- solution
Infection → antibiotic
Withdrawl → benzo (dizepam or chlordiazepoxide) to prevent seizures and delirium tremens

Antipsychotic or neuroleptic meds if pt has agitation, sleep disturbances, or hallucination

Q

Nonmed treatment for delirium

A

-Early mobility, families in care, restricting the use of analgesics or sedatives

-Monitoring proper hydration and nutrition, daily exercise, well lit enviornment

-When fluid & e- are balanced → return to regular cognitive fx

-Infection is resolved → return to regular cognitive fx

-the plan of care: reestablish electrolyte or vitamin imbalances, improve blood sugar levels, restore the client’s temperature, adjust medications, or withdraw the client successfully from alcohol or other substances.

-Mediterranean diet (fish, veg, plant oils)
-Exercise
-DASH diet
