Subtype of delirium occurring during PTA characterized by excesses of behavior like aggression, akathisia, disinhibition and/or emotional lability
Usually with frontotemporal lesions (affecting arousal, attention, executive control, memory, limbic behavioral functions)
Usually occurs as patients become more responsive in early stages of recovery
Usually lasts 1-14 days but can last longer
First Line
safe, structured, low-stimulus environment
- Quiet private room, remove lines/tubes as much as possible
- Floor bed with padded side panels, sitter, avoid taking patient off unit
- One person speaking, one topic/idea at a time, maintain familiar staff
- Allow patient to pace or move in bed with supervision, tolerate some restlessness
Second Line
Pharmacotherapy
- Antipsychotic agents: via dopamine pathways
- Could cause neuroleptic malignant syndrome (treat w/ dantrolene/beta blockers)
block D2 receptors (and H, 𝛂1, cholinergic receptors) |
Haldol can prolong PTA and slow motor recovery. Avoid in TBI! |
less D2 blockage, more serotonin blockage (5-HT2) Less likely motor side effects but frequent metabolic side effects |
|
risperidone (Risperdal) | least anticholinergic, can be stimulating, can impede cognitive recovery after TBI |
quetiapine (Seroquel) | sedating, less motor SEs, prolongs QT; usually start at 25-50mg qHS, can titrate up by 25-50mg every 1-2 days to 300mg/day but monitor QTc closely |
olanzapine (Zyprexa) | sedating, metabolic SEs, acute IM form; usually start at 2.5-5mg qHS, can titrate up by 5-10mg every 1-2 days; IM can be from 5-10mg, 2h after initial dose and 4h after 2nd dose should be allowed to evaluate response (max 20mg/day |
Can impair motor recovery, cause transient recurrence of hemiparesis or paradoxical agitation, increase confusion in those emerging from PTA | |
midazolam, lorazepam (short acting) | lowest dose possible, only if necessary |
Have best evidence for efficacy in treating post-traumatic agitation No effect on motor recovery, can cause lethargy/depression at high doses |
|
propranolol | 10-20 mg q6-8h |
valproic acid (Depakote, Depakene) | 1250-1800 mg/day |
carbamazepine (Tegretol) | 400-800 mg/day |
oxcarbamazepine (Trileptal) |
amitriptyline (Elavil) | 25-150 mg/day |
sertraline (Zoloft) | 25-300 mg/day |
trazodone | 25-300 mg/night |
buspirone | 10-45 mg/day |
bupropion | 150 mg/day |
