Editor's Notes
- #2: Key Lecture Points Review commonly abused drugs and their common signs and symptoms. Review clues of drug use by the patient. Review the pertinent history you should obtain when managing a patient who may be under the influence of drugs. Explain how to interact with a patient who may be impaired from substance abuse. Explain how to manage the patient who is injured, under the influence, and uncooperative. Be familiar with and discuss your local laws regarding restraining a patient.
- #6: NOTE: Substance abuse includes abuse of alcohol, drugs, or both. Substance abuse is associated with a number of traumatic events, often resulting from accidents, car crashes, suicides, homicides, and other violent crimes. One study found a high rate of alcohol and illicit drug use in patients who die from trauma (Journal of American College of Surgeons). Number of seriously injured trauma patients are under influence of alcohol or some other substance. History supplied by the patient or bystanders can also help to establish whether substance abuse is involved. Obtain history from patient and bystanders, but remember many patients (and bystanders) deny substance use. If possible, inspect patient's surroundings for clues that drugs or alcohol may have been used. Note any alcoholic beverage bottles, pill containers, injection equipment, smoking paraphernalia, or unusual odors.
- #7: It is extremely difficult to differentiate between patients under the influence and those experiencing a medical and/or trauma emergency.
- #9: Therefore, the patient’s report of how much was used is helpful, but not 100% reliable indication of what symptoms to expect.
- #11: “N-bomb” includes a group of designer drugs called 25B- NBOMe, 25C- NBOMe, 25I- NBOMe. These drugs target serotonin receptors.
- #12: IMAGE: Needle marks NOTE: Other items in list covered on next slides ITLS Primary and Secondary Surveys should follow the ITLS guidelines. These are particular aspects to be aware of when conducting the exam when you suspect the patient has abused substances. An altered mental status can be seen in every form of substance abuse.
- #13: Remember that altered level of consciousness is always due to a head injury, shock, or hypoglycemia, until proven otherwise. An altered mental status can be seen in every form of substance abuse.
- #14: Speech can be slurred when using alcohol or sedatives. Hallucinogen use—patient may ramble when talking. Many drugs lessen the patients’ perception and response to pain, making your assessment more challenging.
- #15: Patients who use barbiturates will have pupils that are constricted early on. High dose barbiturates—pupils will eventually become fixed and dilated.
- #17: ITLS approach to patient care will work well, even with patients under the influence of alcohol or drugs. This patient population includes people who are at high risk for infection with hepatitis B, hepatitis C, and HIV.
- #18: Trauma patients under the influence of alcohol or drugs can challenge the provider not only by their traumatic injuries, but also by their attitudes. The way in which you interact with patients who have abused substances can determine if the patient will be cooperative or uncooperative. How you speak to these patients can be as important as what you are doing for them. Avoid yelling at the patient. Respect the patient’s personal space. Avoid talking in a condescending manner. Acknowledge the patient’s concerns. Maintain eye contact.
- #19: Ask them their name and how they would like to be addressed. With this patient population, it may be necessary to orient them to place, date, and what is going on. These patients may need to be reoriented frequently. Often, a lack of respect can be heard in tone of your voice or how you say things, not just in what you say. The patient who is scared or confused may be more comfortable with what is taking place if you recognize and address these feelings. Be gentle but firm. Explain all treatment interventions before they are performed. Patients may be confused and not realize that they need to hold still while you are trying to stabilize them on a backboard. Closed-ended questions are questions that can be answered with a yes or no. These patients may only be able to concentrate for short periods of time, and they may ramble when asked open-ended questions that require a full answer. Consider getting as much of history as you can from relatives, friends, or bystanders.
- #20: Watch for clues regarding physical violence, such as verbal threats, aggressive posture by the patient, rapidly shifting eye movements, and fist clenching. If the situation becomes physical, you should back out to safety and allow law enforcement officers to perform their job.
- #22: Patients are often difficult to handle because they can display incredible strength. Deaths attributed to the patient being placed in a prone position will hands behind the back and legs forward (“hog position”).
- #23: It is believed that the effects of stimulants (e.g., cocaine, methamphetamine) lead to cardiac dysrhythmias and their signs reflect sympathetic nervous system stimulation. Cardiac monitoring leads may be difficult to apply due to diaphoresis. Intoxicated patients, especially those on stimulants, are at risk of death during transport.
- #24: Know your jurisdiction’s policy on refusal of care. For emergency care providers to treat, patients must consent to care. Unresponsive patients are often able to be treated under implied consent.
- #25: Restraint training is essential. In some circumstances, chemical restraints may be required. Know requirements in local jurisdiction for restraining patients against their will. Know who can restrain, under what conditions a patient can be restrained, and what types of devices can be used, like soft restraints. Securely strapping a patient to a backboard with use of a cervical collar and head motion-restriction device will serve to restrain most patients. Caution must be taken not to worsen any current injuries or inflict any new ones. Restrained patients may struggle so hard that spinal motion restriction is rendered ineffective. Reeves sleeve is one of the few pieces of equipment that is very effective in providing both restraint and motion restriction. Crews should plan and practice procedures for restraining patients. Reassess restrained patients often.
- #26: Based upon a 2009 survey of teenagers, the National Institute on Drug Abuse (NIDA) concluded that many drug use trends are declining. However, they reported that the perception that Methylenedioxymethamphetamine MDMA (ecstasy) is harmful is declining and this might be a precursor to an increase in use of this drug. The NIDA also expressed concern about the nonmedical use of the narcotics Vicodin (hydrocodone) and OxyContin (oxycodone).
- #27: People who abuse alcohol and drugs are frequently involved in trauma. Be prepared to treat them often. Determining that your patient has abused some substance will allow you to pay attention to specific areas for critical changes as well as provide lifesaving interventions that may be indicated for individual substances. If you must restrain a patient for his or her safety, do so in a preplanned manner that is most sensitive to your patient's needs.
