When overdoses go wild: Protecting the EMS provider
EMS providers face a variety of hazards while on the job. About 10 percent of all EMS provider injuries are a result of some form of violence . An unknown percentage of these violent acts involve patients who have abused some form of drug or medication, and present in an altered state. This article explores violent patient behavior associated with substance abuse, as well as how to anticipate and manage these situations as to minimize their danger.
Epidemiology of patient violence
Chemistry of emotion and behavior
How we react to certain situations is rooted within the body's autonomic nervous system. Two branches, the sympathetic and parasympathetic systems work in conjunction in each other, regulating most bodily functions on a minute-to-minute basis.
The sympathetic system is the source of the well-described "flight or fight" reflex, where the body is programmed to react to sudden stress by increasing heart rate, contractility, and respiratory rate. Blood is shunted away from the skin and GI tract and toward the heart, lung, kidneys and the broad muscle beds. The brain experiences fear, stress and anxiety. Altogether, this response to a stressor serves the body well in protecting it from harm. But this same response may be triggered by the effects of substance abuse and overdose, creating a potentially dangerous situation for patients and EMS providers alike.
Specific drugs related to violence
Alcohol is considered to be the most common drug associated with violence. People can become angry and aggressive while under the influence of ethanol. Being verbally or physically abused by another person is twice as likely to occur if ethanol is involved .
What makes ethanol-driven violence more unpredictable is that there is no dose-effect relationship. It is unclear why ethanol can make one person feel happy and sleepy, but cause another person to be hostile and violent.
Ethanol is also commonly used in conjunction with other drugs. It can have an additive effect, especially with other GABA related drugs such as benzodiazepines (diazepam and midazolam, for example.)
An emerging stimulant, alpha-PVP is a strong stimulant with highly addictive properties. It belongs in the same classification as "bath salts." People who have used alpha-PVP, also known as Flakka, have been known to be very physically violent, paranoid and difficult to control. The behavior is reminiscent of the older drug phenycycline, or PCP.
General safety practice guidelines
However in most circumstances EMS and other public safety providers must quickly develop a plan to safely manage a potentially violent patient. Maintaining a heightened sense of situational awareness by all rescuers can keep the scene in control and anticipate sudden changes in the patient's behavior. The EMS provider rendering direct patient care should be covered by another member of team who can quickly assist if the patient's behavior changes during the assessment and management phase.
Consider the possibility of sudden violence if the patient is exhibiting one or more of these behaviors:
The initial management approach is to stay calm and listen. Allow the patient to vent while sizing up the situation for potential weapons and escape routes. Actively engage with the patient's conversation; acknowledge what the patient is saying or feeling while not injecting your own opinion into the discussion. Affirm the patient's statements ("I hear you saying…."); this may help the patient calm down some and establish a working relationship or rapport with you.
Avoid trapping patients into situations where they feel they have no options. Give options whenever possible. An example might be the choice of walking to the unit or being wheeled on the gurney. The choices should be realistic; someone with altered mental status would not have the option of refusing care.
If verbal defusing techniques are not effective, a plan must be rapidly developed to restrain the patient physically, chemically or both. No fewer than five rescuers are needed to safely restrain a patient. The team must quickly decide who will gain the patient's attention while the other embers surround the patient. Control is taken in one simultaneous motion and soft restraints applied.
Patients must be restrained in a supine position. Chemical restraint with benzodiazepines or haloperidol have been demonstrated to be safe and effective. If you suspect excited delirium consider ketamine for patient sedation.
Most importantly, EMS providers must remain in control of their own emotions in these highly stressful situations. Remaining calm reduces the chances of escalating an already bad situation into a disastrous one.
