Trauma Bay Adult Acute Agitation Management

Purpose:

Traumatically injured patients presenting to the emergency department (ED) experiencing acute agitation have the potential to harm themselves, hospital staff, and others.  Safe and expeditious management of agitation is imperative to prevent potential further harm.  However, treatment of acute agitation is challenging due to the heterogenicity of the patient population, cause or source of agitation, and the available therapeutic treatment options.

There are two critical factors that are essential to the management of agitation – early recognition and targeted intervention to the etiology driving the patient’s acutely agitated state.  This treatment protocol is designed to help streamline the care of this difficult patient population. 

Background/Definitions:

Acutely agitated and/or violent behaviors displayed by trauma patients interfere with the required medical care of the patient.  Acute agitation is a medical emergency.  Determining the cause or causes of agitation will allow for a more informed management strategy for the patient.  However, because of constraints on time, limited information, and lack of patient engagement, one must assess and identify the underlying cause(s) expeditiously.   The goal of acute agitation treatment is to calm the patient in the least invasive way, without causing oversedation.

Per policy TX-1, the philosophy of Nebraska Medicine is to reduce/limit the use of physical and chemical restraint while maintaining the safety and preserving dignity, rights, and wellbeing of patients.  Nebraska Medicine respects the patient’s right to be free of restraints of any form that are not medically necessary. If a patient’s condition necessitates the use of restraints, the safety and wellbeing of the patient and medical staff caring for the patient is the primary focus of the medical team.

·         Severe Agitation:

o   Currently violent or aggressive, attacking people and/or objects.

·         Moderate Agitation:

o   Physically or verbally threatening, difficult to redirect, extremely active, however, not violent.

·         Mild Agitation:

o   Signs of overt physical or verbal activity but redirectable.

·         De-escalation:

o   A combination of both verbal and nonverbal strategies intended to calm the patient down to cooperate with their care.

·         Sedation and Analgesia:

o   Use of pharmacologic agents to create a drug-induced state to reduce physiologic and psychological stress to a patient undergoing medical, surgical, or diagnostic procedures.

 

Common Medical Causes of Acute Agitation

Type

Examples

Neurological

Traumatic brain injury, intracranial hemorrhage, seizure/post-ictal, stroke, encephalopathy

Infectious

Meningitis, sepsis, urinary tract infection (elderly)

Metabolic

Electrolyte disturbance, hypoglycemia

Respiratory

Hypoxia

Toxicological

Environmental toxin, medication reaction, illicit drug use

Endocrine

Thyrotoxicosis, myxedema coma

Other

Hyper- or hypothermia, acute pain

 

Practice Recommendations for Medical Management:

·         De-escalation should always be attempted prior to medication management and physical restraint.

·         Restraint may only be imposed to ensure the immediate physical safety of the patient, staff or others and must be discontinued as soon as safely possible, regardless of the scheduled expiration of the order.

·         TX_01 will be followed if/when restraint use is required.

·         Follow the management considerations, listed in the table below, using the preferred agent(s) as listed in Attachment A.  Preferred agents show better clinical properties, including onset of action, efficacy, and lower incidence of adverse effects.

 

Management Considerations for Agitation

Severity of Agitation

Preferred Route of Administration

Dosing Considerations

Special Populations

Severe

IV, when able

IM, if IV not available

Maximize dose of first agent used, allowing for the onset and effects of the previous dose prior to administering second dose

Dosing adjustments may be required for elderly, renally/hepatically impaired, and/or when given medication(s) prior to arrival.


Lower doses may be required when using concomitant sedating medications.

Moderate

IV, when able

IM, if IV not available

Smaller doses may be sufficient (as compared to what is required for severe agitation)

If able/known, use a patient’s home regimen when patients can tolerate oral therapy.

Mild

PO

If able/known, use a patient’s home regimen when patients can tolerate oral therapy.

Management Considerations for Ketamine:

At Nebraska Medicine, ketamine is restricted to the following indications:

·         Induction for rapid sequence intubation

·         Ventilator management

·         Procedural sedation

·         Subanesthetic analgesia (restricted ordering to anesthesiology, pain management, emergency medicine, and pediatric critical care medicine)

If ketamine is required for the use of acute agitation, the institutional policy, MS_15 for procedural sedation or MP_33 for subanesthetic ketamine for pain management, will need to be followed.  A provider must remain at bedside.


Dosing recommendations:

·         Sub-Anesthetic Ketamine for Pain

o   Must be ordered by emergency medicine provider (while patient is in the ED).

o   Use dosing recommendations per MP_33

·         Procedural Sedation
