Injuries and Mass Trauma Events

 

v Coping With a Traumatic Event–Information for the Public

What is a traumatic event?

An event, or series of events, that causes moderate to severe stress reactions, is called a traumatic event. Traumatic events are characterized by a sense of horror, helplessness, serious injury, or the threat of serious injury or death. Traumatic events affect survivors, rescue workers, and friends and relatives of victims who have been directly involved. In addition to potentially affecting those who suffer injuries or loss, they may also affect people who have witnessed the event either firsthand or on television. Stress reactions immediately following a traumatic event are very common; however, most of the reactions will resolve within ten days.

Why do these injuries occur in mass trauma events?

What are some common responses?

A person’s response to a traumatic event may vary. Responses include feelings of fear, grief and depression. Physical and behavioral responses include nausea, dizziness, and changes in appetite and sleep pattern as well as withdrawal from daily activities. Responses to trauma can last for weeks to months before people start to feel normal again. 

Most people report feeling better within three months after a traumatic event. If the problems become worse or last longer than one month after the event, the person may be suffering from post-traumatic stress disorder (PTSD). 

What is PTSD?

Post-traumatic stress disorder (PTSD) is an intense physical and emotional response to thoughts and reminders of the event that last for many weeks or months after the traumatic event. The symptoms of PTSD fall into three broad types: re-living, avoidance and increased arousal.

Other symptoms linked with PTSD include: panic attacks, depression, suicidal thoughts and feelings, drug abuse, feelings of being estranged and isolated, and not being able to complete daily tasks.

What can you do for yourself? 

There are many things you can do to cope with traumatic events.

What can you do for your child?

Let your child know that it is okay to feel upset when something bad or scary happens.

When should you contact your doctor or mental health professional?

About half of those with PTSD recover within three months without treatment. Sometimes symptoms do not go away on their own or they last for more than three months. This may happen because of the severity of the event, direct exposure to the traumatic event, seriousness of the threat to life, the number of times an event happened, a history of past trauma, and psychological problems before the event. 

You may need to consider seeking professional help if your symptoms affect your relationship with your family and friends, or affect your job. If you suspect that you or someone you know has PTSD, talk with a health care provider or call your local mental health clinic.

v Coping With a Traumatic Event–Information for Health Professionals

How do you interact with patients after a traumatic event?

The clinician should be alert to the various needs of the traumatized person.

What can you do to help patients cope with a traumatic event? 

Explain that their symptoms may be normal, especially right after the traumatic event, and then encourage patients to:

                                   - volatile emotions    - pain                            use or abuse

                                      - jumpiness

Who is at risk for severe and longer lasting reactions to trauma? 

Some people are at greater risk than others for developing sustained and long-term reactions to a traumatic event including disorders such as post-traumatic stress disorder (PTSD), depression, and generalized anxiety. Factors that contribute to the risk of long-term impairment such as PTSD are listed.

What can you do to treat patients in response to a traumatic event?

Helping survivors of traumatic events, their family members, and emergency rescue personnel requires preparation, sensitivity, assertiveness, flexibility and common sense.

What can health departments do to prepare for a mass trauma event?

  1. Notify doctors and hospitals in advance about the kinds of injuries to expect following a disaster.

  2. Review CDC’s Mass Trauma Response Tools, including the Rapid Assessment Instrument for Injuries and Other Medical Conditions.

  3. Establish partnerships with hospitals in your state to develop protocols for rapid assessment, casualty prediction, hospital capacity information, and patient care.

  4. Prepare signs. Persons with hearing damage as a result of a recent explosion may not be able to follow verbal directions. They would benefit from explicit, easy-to-read signs and handouts that are strategically located and distributed in hospitals and clinics.

  5. Communicate to health care professionals, media, and general public that medical personnel should examine all cuts and wounds resulting from mass trauma events. Tiny debris particles from explosions, building collapse, or other disaster events can be embedded into wounds and are often highly contaminated. Even minor wounds are at risk for infection. Medical personnel should evaluate all wounds, and a tetanus shot should be considered.

What can health departments do after a mass trauma event?

Mass trauma events can create both real and perceived difficulties in accessing medical care. Outpatient and inpatient services at the hospitals closest to the event will likely be the ones most affected during the first 16 hours after an event. In the days following a mass trauma event, all health care facilities are often underutilized. Health Departments can:

v Burns

Mass trauma and disasters such as explosions and fires can cause a variety of serious injuries, including burns. These can include thermal burns, which are caused by contact with flames, hot liquids, hot surfaces, and other sources of high heat as well as chemical burns and electrical burns. It is vital that people understand how to behave safely in mass trauma and fire situations, as well as comprehend basic principles of first aid for burn victims.

Background Information

- Approximately 50,000 of these require hospitalization; 

- Approximately 20,000 have major burns involving at least 25 percent of their total body surface; 

- Approximately 4,500 of these people die.

First Aid

What you do to treat a burn in the first few minutes after it occurs can make a huge difference in the severity of the injury.

Immediate Treatment for Burn Victims

  1. "Stop, Drop, and Roll" to smother flames.

  2. Remove all burned clothing. If clothing adheres to the skin, cut or tear around burned area.

  3. Remove all jewelry, belts, tight clothing, etc., from over the burned areas and from around the victim’s neck. This is very important; burned areas swell immediately.

Types of Burns

First-Degree Burns

First-degree burns involve the top layer of skin. Sunburn is a first-degree burn.

v Brain Injuries and Mass Trauma Event–Information for the Public

Brain injuries can occur during mass trauma events. If you think you or someone you know has brain injuriy, seek medical attention.

What is a brain injury?

Brain injuries are caused by a blow or jolt to the head that can disrupt the normal function of the brain. These injuries can range from mild to severe. Mild brain injuries are also known as "concussions" and are usually not life threatening. But sometimes even mild brain injuries can cause serious, long-lasting problems.

Why are brain injuries a problem in mass trauma events?

In mass trauma events such as the World Trade Center attack or the Oklahoma City bombing, brain injuries were caused by flying debris or by a person falling and hitting their head. A blast from an explosion can also cause a brain injury, even when there is no direct contact with an object.

What are some common signs of a brain injury?

The signs of a brain injury may be slight and patients, family members and doctors may miss these problems. People with a brain injury may look fine even though they’re acting or feeling differently. The most common signs include:

What can you do to get help?

If you or someone you know has been in a mass trauma event and you think you may have a brain injury, see your doctor or health care provider. Show them this fact sheet and tell them about the problems you are having. The doctor may be able to help you find a health care provider who has special training in the treatment of brain injury. Your doctor may refer you to a neurologist, neuropsychologist, neurosurgeon, or specialist in rehabilitation (such as a speech pathologist). Getting help soon after the injury by trained specialists may speed your recovery.

Brain Injury Facts 

Signs and Symptoms after an MTBI

Early MTBI symptoms may appear mild, but they can lead to a significant, life-long impairment, affecting an individual’s ability to function cognitively, physically, and psychologically. In addition to the obvious, look for these signs and symptoms:

¨ Cognitive

¨ Physical

¨ Behavioral

Diagnosis

Diagnosing an MTBI can be a challenge because symptoms are often common to other medical problems, and the severity of the symptoms can change over time. Any patient with a history of head trauma suffering from confusion, disorientation, or amnesia of events around the time of injury, loss of consciousness of 30 minutes or less, neurological or neuropsychological problems, or with a Glasgow Coma Scale (GCS) Score of 13 or higher, may have an MTBI. Taking a careful medical history can be key to detecting an MTBI. Any unusual or unexplained signs or symptoms should be evaluated further.

Treatment 

MTBI treatment varies from person to person. Educating the patient and his/her family about the possibility of a brain injury and the symptoms that may be experienced as a result of such an injury is critical. Referral to specialists in neurology, neuropsychology, or rehabilitation may be appropriate.

v Chemical Agents: Facts About Personal Cleaning and Disposal of Contaminated Clothing

Some kinds of chemical accidents or attacks may cause you to come in contact with dangerous chemicals. Coming in contact with a dangerous chemical may make it necessary for you to remove and dispose of your clothing right away and then wash yourself. Removing your clothing and washing your body will reduce or remove the chemical so that it is no longer a hazard. This process is called decontamination.

People are decontaminated for two primary reasons:

  1. to prevent the chemical from being further absorbed by their body or from spreading on their body, and

  2. to prevent the chemical from spreading to other people, including medical personnel, who must handle or who might come in contact with the person who is contaminated with the chemical.

Most chemical agents can penetrate clothing and are absorbed rapidly through the skin. Therefore, the most important and most effective decontamination for any chemical exposure is decontamination done within the first minute or two after exposure.

How to know if you need to wash yourself and dispose of your clothing

In most cases, emergency coordinators will let you know if a dangerous chemical has been released and will tell you what to do.

In general, exposure to a chemical in its liquid or solid form will require you to remove your clothing and then thoroughly wash your exposed skin. Exposure to a chemical in its vapor (gas) form generally requires you only to remove your clothing and the source of the toxic vapor.

If you think you have been exposed to a chemical release, but you have not heard from emergency coordinators, you can follow the washing and clothing disposal advice in the next section.

What to do

Act quickly and follow the instructions of local emergency coordinators. Every situation can be different, so local emergency coordinators might have special instructions for you to follow. The three most important things to do if you think you may have been exposed to a dangerous chemical are to (1) quickly remove your clothing, (2) wash yourself, and (3) dispose of your clothing. Here’s how:

¨ Removing your clothing:

¨ Washing yourself:

¨ Disposing of your clothes:

After you have removed your clothing, washed yourself, and disposed of your clothing, you should dress in clothing that is not contaminated. Clothing that has been stored in drawers or closets is unlikely to be contaminated, so it would be a good choice for you to wear.

You should avoid coming in contact with other people who may have been exposed but who have not yet changed their clothes or washed. Move away from the area where the chemical was released when emergency coordinators tell you to do so.
