Secondary injury is a term applied to the destructive and self-propagating biological changes in cells and tissues that lead to their dysfunction or death over hours to weeks after the initial insult (the “primary injury”).
What is an example of a secondary injury?
Secondary injuries are injuries that lead to additional injuries. For example, an individual has a hip injury that compromises the way the individual walks and carries items, thus resulting in a strained back. The back injury would be considered a secondary injury.
What causes secondary injury?
Secondary injury is an indirect result of the injury. It results from processes initiated by the trauma. It occurs in the hours and days following the primary injury and plays a large role in the brain damage and death that results from TBI.
What is the difference between primary and secondary injury?
Whereas primary brain injury (focal and diffuse) results from mechanical injury at the time of the trauma, secondary brain injury is caused by the physiologic responses to the initial injury.What is considered a secondary brain injury?
Secondary brain injury refers to the changes that evolve over a period of hours to days after the primary brain injury. It includes an entire series of steps or stages of cellular, chemical, tissue, or blood vessel changes in the brain that contribute to further destruction of brain tissue.
What is a secondary injury to the spinal cord?
As the name suggests, the secondary injury cascade is a series of changes—often developing one after the other—that begin within just a few hours after the SCI and may continue more than 6 months past the initial injury.
What does secondary to the accident mean?
Secondary injuries are injuries that occur as the result of other injuries. Rather than being present at the time of the initial accident, secondary injuries can become present days, weeks, or even months following it. They are the result of the changes in the body that occur because of the original injury.
What are the 7 types of TBI?
- Hematoma. A hematoma is a collection, or clotting, of blood outside the blood vessels. …
- Hemorrhage. A hemorrhage is uncontrolled bleeding. …

- Edema. …
- Skull fracture. …
- Diffuse axonal injury.
What type of injuries will most likely occur if a passenger?
a. The greater the height of the fall, the greater the potential for injury. b. A fall from more than 15′ or 3 times the patient’s height is considered significant.
What is a deceleration injury?deceleration injury, impact injury to a body within or upon a rapidly moving object caused by the forces exerted when the object is brought to a sudden halt.
Article first time published onWhat is secondary hypoxia?
Prolonged hypoxia can cause coma, seizures, and even brain death. Hypoxia is a possible secondary complication that can develop over a period of hours to days after the initial TBI.
What are some manifestations of secondary brain injury?
- Severe, frequent headaches.
- Vision problems or loss of visual stability.
- Memory loss or difficulty with short-term memory.
- Insomnia or hypersomnia.
- Dizziness or fainting.
- Moodiness, acute depression, or personality changes.
- Changes in eating habits.
Which pathology increases a patient's risk for secondary brain injury?
Arterial hypotension is a major risk factor for secondary brain injury, but hypertension with a loss of autoregulation response or excess hyperventilation to reduce ICP can also result in a critical condition in the brain and is associated with a poor outcome after TBI.
What is considered traumatic brain injury?
Traumatic brain injury (TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull.
What is classification of head injury?
Head injuries may be categorized in several ways. Injuries are classified by mechanism (closed vs. penetrating injury), morphology (fractures, focal intracranial injury and diffuse intracranial injury), and severity (mild, moderate and severe).
What is a level 3 brain injury?
Penetrating Brain Injuries. Penetrating brain injuries occur when some type of object pierces through the skull. This may cause the object, or hair, skin, or fragments of the skull, to make contact with the brain.
What is secondary damage on a car?
A secondary car accident is one that occurs as a direct or indirect consequence of a previous accident, known as the primary accident. These secondary accidents typically happen shortly after a primary accident, and in the near vicinity of the primary accident.
What is a tertiary blast injury?
Tertiary blast injury occurs when a person is physically thrown by the blast, which usually causes direct impact trauma. For example, being thrown by the blast might cause the head to strike the ground or a wall.
What are some common sports injuries?
- Achilles tendon injuries. Your Achilles tendon is the thick, corded tissue that connects your calf muscle (in the back of your lower leg) to your heel. …
- Broken bones. …
- Dislocations. …
- Jumper’s knee. …
- Little League elbow. …
- Rotator cuff injuries. …
- Runner’s knee. …
- Shin splints.
When does secondary spinal cord injury occur?
Overview of Secondary Mechanisms of Spinal Cord Injury. Secondary injury begins within minutes following the initial primary injury and continues for weeks or months causing progressive damage of spinal cord tissue surrounding the lesion site (7).
What is Brown Séquard syndrome?
Brown-Séquard syndrome is a rare spinal disorder that results from an injury to one side of the spinal cord in which the spinal cord is damaged but is not severed completely. It is usually caused by an injury to the spine in the region of the neck or back.
What secondary clinical problems may occur from a spinal cord injury?
In this paper, we review data about common secondary long-term complications after SCI, including respiratory complications, cardiovascular complications, urinary and bowel complications, spasticity, pain syndromes, pressure ulcers, osteoporosis and bone fractures.
Which of the six most common mechanisms of injury has the highest mortality for all age groups?
Motor vehicle collisions are the leading cause of trauma death in all age groups between 1 to 65 years. In individuals over 65 years, falls become the leading cause of death.
Is a dog bite blunt or penetrating?
The most common type of vessel trauma due to a canine bite was an occlusion (60%) [15], but there are usually two components of a dog bite, a penetrating injury usually causing puncture or laceration to the vessel and a blunt one which may be the more clinically significant injury [13].
What does the platinum 10 minutes refer to?
An analogous concept, the “platinum 10 minutes” places a time constraint on the pre-hospital care of seriously injured patients: no patient should have more than 10 min of scene-time stabilization by the prehospital team prior to transport to definitive care at a trauma centre.
What causes secondary brain injury after head trauma?
Secondary injury may occur hours or even days after the inciting traumatic event. Injury may result from impairment or local declines in cerebral blood flow (CBF) after a TBI. Decreases in CBF are the result of local edema, hemorrhage, or increased intracranial pressure (ICP).
What are at least 5 symptoms of mild traumatic brain injury?
PhysicalThinking and RememberingSleepDizziness or balance problemsFeeling slowed downSleeping more than usualFeeling tired, no energyFoggy or groggyTrouble falling asleepHeadachesProblems with short- or long-term memoryNausea or vomiting (early on)Trouble thinking clearly
What are two of the three classic signs of an acute abdominal injury?
Signs and symptoms include abdominal pain, tenderness, rigidity, and bruising of the external abdomen.
What is difference between acceleration and deceleration?
In literal sense, acceleration is considered to describe an increase or positive change of speed or velocity. On the other hand, deceleration is considered to describe a decrease or negative change of speed or velocity.
What is a blunt trauma?
Definitions. Blunt force trauma: Injuries resulting from an impact with a dull, firm surface or object. Individual injuries may be patterned (eg ,characteristics of the wound suggest a particular type of blunt object) or nonspecific.
What is an hypoxic injury?
Hypoxic brain injuries are brain injuries that form due to a restriction on the oxygen being supplied to the brain. The restricted flow of oxygen causes the gradual death and impairment of brain cells.
