The term trauma comes from the Greek and means"injury, wound". On the one hand, doctors use it to describe a damaging (traumatizing) effect on the organism. This can be an accident or a psychological injury, for example. On the other hand, the resulting consequential damage is also a trauma, such as a
Depending on the number of injured organs and tissues, a distinction is made between monotrauma and polytrauma.
Monotrauma (mono = single) involves injury to one organ, which in most cases is not life-threatening. This is mainly due to the fact that the course of the accident in polytrauma is generally much less severe than in monotrauma. However, there are also very serious and life-threatening individual injuries, for which the term barytrauma ("bary" = serious) has become established. Life-threatening individual injuries include, for example
The life-threatening nature of these individual injuries results, for example, from the importance of the organ (craniocerebral injuries) or the possible loss of blood, which can be considerable (pelvic injuries).
Polytrauma is the term used to describe a simultaneous, severe injury to several organs. It is a multiple injury and, as the name ("poly" = many) suggests, affects several areas of the body or organ systems. A polytrauma is basically a serious and life-threatening situation in which either all the injuries taken together or a single one of them is life-threatening.
There are many different types of trauma. What they all have in common is the application of violence to the body, which results in a threat to the integrity of the body. This violence can be roughly divided intophysical and psychological violence.
Physical violence includes
- mechanical
- physical or
- chemical
effects.
Mental trauma includes all psychologically stressful situations such as
What exactly are mechanical traumas?
Mechanical trauma can occur in many different ways. They are usually caused by the use of weapons or sharp objects, but often also by bare hands.
In particular, stab wounds or cuts caused by the use of sharp objects can lead to severe bleeding if larger arteries are severed.
Gunshot wounds can also lead to very serious incidents and assume life-threatening proportions. The dangerous thing about gunshot wounds is that once the bullet has entered the body, it spreads even further and can cause massive soft tissue damage. This tissue damage is often much larger and more pronounced than the usually small entry point of the bullet would suggest.
Blunt trauma is caused by a violent impact without injury to the skin. This can be caused, for example, by blows with a fist or hard objects, but also by joint dislocations (dislocations of joints). Blunt injuries can be very serious, but they are often much more difficult to diagnose than sharp injuries. This is because sharp injuries can be seen with the naked eye, whereas most of the blunt trauma is internal.
High-impact traumas, which are injuries caused by the impact of very high kinetic energy, are also mechanical injuries. They always occur when the body is moving at high speed and is abruptly decelerated. Typical examples of high-speed traumas are car and traffic accidents as well as sports accidents, such as skiing or cycling.
Finally, bite wounds are also mechanical injuries, most commonly caused by animal bites. However, human bites are also not uncommon and are often more difficult to treat. This is because bite injuries caused by humans are associated with a significantly higher risk of infection.
What is meant by physical trauma?
Physical trauma refers to all injuries and consequences caused by extreme and pathological environmental influences. These include, among others
- Burns: These result from flames, fire, hot water, but also sun exposure
- Cold trauma: Prolonged exposure to cold ambient temperatures, ice or cold objects can lead to massive cold damage to the skin, as well as cooling of the entire body and even cardiac arrest
- Radiation damage: This primarily refers to damage caused by radioactive radiation, but solar radiation and radiation from the ultraviolet range can also lead to radiation damage
- Noise damage: This is also known as acoustic trauma and is caused, for example, by an explosion. People who are exposed to high levels of noise at work must wear appropriate noise protection to preserve and protect their hearing
- Pressure injuries: These are known as barotrauma and can result from damage to the body or organs due to a change in ambient pressure. Typical examples of pressure injuries are sports injuries during deep-sea diving or injuries during air sports.
How do chemical traumas occur?
Chemical traumas are injuries to the body caused by the effects of toxic substances on the body. These substances can have a damaging effect on the body in liquid, solid or gaseous form. This can occur from the outside via the skin surface or from the inside via mucous membranes and the bloodstream.
Chemical trauma includes in particular
- Poisoning: Here the toxins affect the inside of the body. They are absorbed via the mouth, nose or, rarely, the rectum and enter the bloodstream via absorption in the intestines or lungs. There they are distributed throughout the body and lead to symptoms of poisoning in various organs. Poisoning is typically caused by medication, food or drink. Poisoning is also frequently caused by an overdose of a drug that is in principle harmless or even beneficial to health, which only has a toxic effect due to the excessive quantity.
- Chemical burns: Typical of chemical burns are the damaging effects on the skin and mucous membranes, which are caused in particular by acids or alkalis. The larger the damaged area of skin or mucous membrane, the more severe the effects on the whole organism. If large parts of the skin or mucous membrane are affected, life-threatening conditions can arise.
What are the causes of psychological trauma?
The causes of psychological trauma can be very diverse, which is why only a few examples are listed below:
- Loss of loved ones
- Jealousy
- stress
- War and persecution
- Sexual abuse
- childhood neglect
- sudden infant death syndrome
- divorce/separation
- bullying
- fears
- a life-threatening illness
- natural disasters
- unemployment
Trauma physicians (trauma surgeons and emergency physicians) are responsible for all physical trauma consequences. Trauma surgery and emergency medicine are a broad field and trauma physicians must be qualified in many areas. These primarily include
- first aid at the accident site
- shock treatment measures and
- subsequent surgical/orthopaedic treatment in hospital
Trauma physicians must be able to quickly recognize and treat various traumas © Chalabala | AdobeStock One of the most important tasks in trauma surgery is the treatment of injuries to the musculoskeletal system. These include bone fractures or muscle and tendon injuries.
The transition from the field of activity of a trauma surgeon to that of an orthopaedic surgeon is fluid. For this reason, these specialist training programs were merged in Germany in 2005 ("Specialist in Orthopaedics and Trauma Surgery").
The first aim of traumatology is to avert acute danger to life and to contain any complications. After this, the patient is usually initially cared for in the intensive care unit.
Polytrauma patients must be cared for in hospital by a well-trained and experienced team of specialists . This includes the following specialists, for example:
- Trauma surgery: take care of all bone and joint injuries
- Emergency medicine: are responsible for the initial treatment measures at the scene of the accident and in the emergency room
- Anesthesia and intensive care: treat all severe shock conditions and organ injuries
- Visceral surgery: are responsible for operations on injuries to the abdominal organs, such as the intestines or liver
- Vascular surgery: this specialty includes all vascular injuries, i.e. arteries and veins
- Neurology / neurosurgery: for injuries to the head and brain
Such injuries often affect a wide variety of body regions and organ areas. This is why such a team consists of doctors from different specialties, and the above list could go on and on.
Depending on the severity of the trauma, rehabilitation measures are necessary (often over months or years). These are carried out by physiotherapists and occupational therapists .
Patients who have suffered psychological trauma are treated psychotherapeutically as part of psychotraumatology. Specialists in psychiatry are responsible for this. There are different trauma therapies depending on the type and severity of the trauma.
The various therapy methods aim to
- to allow those affected to calm down,
- analyze the psychological problems and
- find a suitable form of therapy.
This includes, for example, behavioral therapy. After the therapy, the patient should feel able to control, limit or resolve the trauma symptoms.
