Agitation After Severe TBI: Least Restrictive Measures and an Expired Restraint Order
Mr. T., 27, sustained a severe traumatic brain injury in a motor vehicle crash three weeks ago, with an admission Glasgow Coma Scale of 10 and a frontal lobe contusion. He is now at Rancho Los Amigos level IV on a locked brain injury unit: confused, agitated, oriented only to his name, pulling at his indwelling catheter and IV. He repeatedly tries to climb over the bed rails and has had two assisted falls with no injury. He is more agitated at night and calls out. His exhausted family asks that he be tied down so he does not hurt himself. There is an as-needed lorazepam order and a PRN restraint order that expired at 07:00; it is now 19:30. His Foley drainage is cloudy, he has not had a bowel movement in three days, and he grimaces when his left shoulder is moved. He cannot reliably self-report pain.
1. Before treating this as a behavioral problem, what underlying causes of agitation would you assess and address?
Read the worked answer
Look for reversible causes first. His cloudy urine raises possible UTI, a classic delirium trigger. No bowel movement in three days suggests constipation or impaction. He grimaces with left shoulder movement, which suggests pain, possibly a fracture or subluxation from the falls, and he cannot reliably report it. Add poor sleep, an unfamiliar noisy unit, and overstimulation at night. In traumatic brain injury, agitation is often the brain's response to pain, infection, constipation, or sleep disruption rather than a primary psychiatric problem, and lorazepam can paradoxically worsen confusion and agitation. So obtain a urine specimen and check temperature, review medications for anticholinergics and opioids, treat pain with scheduled acetaminophen or another non-benzodiazepine, start a bowel regimen, and consolidate nighttime care to protect sleep.
2. The family asks for restraints. What least restrictive measures would you try, and what are the legal and monitoring requirements if a restraint is used?
Read the worked answer
Start with the least restrictive measures: a low bed with mats, a bed or chair alarm, a helmet, a sitter or family presence, removing the Foley and IV as soon as possible (the lines are what he is pulling), a quiet well-lit room near the nurses' station, structured routines, and safe wandering space. A physical restraint requires a current physician order; the one on file expired at 07:00, so using it would constitute false imprisonment or assault. If a restraint is ordered, it must be time-limited, the least restrictive device, monitored every 15 to 30 minutes, with a face-to-face evaluation per policy. Restraints in traumatic brain injury often increase agitation and injury risk. The family's request is understandable, but tying him down is not the first-line answer; educate them about delirium and involve them in redirection, and enlist the provider for a behavioral plan.
3. What findings would prompt you to escalate, and what should the workup and documentation include?
Read the worked answer
Escalate if agitation does not respond to the measures above, if he remains a danger to himself or others despite less restrictive options, or if there are signs of a new medical problem such as fever, focal deficits, changed consciousness, or seizure. Request a delirium workup: urinalysis and culture, complete blood count, basic metabolic panel, glucose, medication review, and consider head CT if there was a recent fall or a change in examination. Involve the physiatrist and neuropsychology to design a behavior plan; if medication is needed, target specific symptoms with the least sedating agent ordered by the physician rather than repeated benzodiazepines. Document refusals, every less restrictive measure tried, and family teaching, because this record demonstrates the standard of care. Reassess restraint need every shift.
