Q

treating deliruim

A

–> Pharmacological Interventions
Eg. Antipsychotics, Benzodiazepines
–> Non-Pharmacological** first line
- Assess safety
- Address modifiable risk factors- decrease sensory
deficits, address pain, sleep
- Modify the environment- minimize noise, keep
sensory stimulus minimal, provide a familiar
environment, ensure that there is appropriate
level of lighting
- COMMUNICATE, COMMUNICATE, COMMUNICATE!
