What is the difference between penetrating and blunt trauma?

Penetrating trauma occurs when a foreign object pierces the skin and enters the body creating a wound. In blunt or non-penetrating trauma the skin is not necessarily broken. In penetrating trauma, the object remains in the tissue or passes through the tissues and exits the body.

What are the physiological effects of trauma trauma?

The Physiological Effects of Trauma Trauma sensitizes the hypothalamic-pituitary-adrenal (HPA) axis, which is the body’s central stress response system. You can think of this as the juncture of our central nervous system and endocrine system, which makes us more reactive to stress and more likely to increase the stress hormone cortisol.

What is penetrating trauma and how is it treated?

Penetrating trauma often causes damage to internal organs resulting in shock and infection.  The severity depends on the body organs involved, the characteristics of the object, and the amount of energy transmitted. Assessment includes x-rays, CT scans, and MRI. Treatment involves surgery to repair damaged structures and remove foreign objects.

What causes a penetrating trauma?

Penetrating trauma involving the ureter occurs in approximately 4% of patients and is most often caused by a stab or gunshot wound.

What is a penetrating injury?

Penetrating injuries can be broadly divided into high-velocity mechanisms, typically caused by gunshots or other missiles, or low-velocity mechanisms, typically associated with sharp objects such as knives, axes, and glass. This distinction is important because of the different underlying mechanisms of cerebrovascular injury and the vastly greater extent of tissue damage seen with high-velocity penetrating trauma.

What is the three port technique for vitrectomy?

We employ the standard three-port technique for vitrectomy, proceeding from anterior to posterior, clearing vitreous opacities ( Fig. 140-18 ). As in vitrectomies for penetrating injuries, it is important to identify the posterior hyaloid and, if it is still adherent to the retina, create a PVD. The stump of proliferation growing through the exit site should be reduced but not eliminated, so that the posterior exit site is not reopened. Retinal breaks are managed with air–fluid exchange and endo-photocoagulation or scleral buckling with cryopexy. We routinely advocate an encircling scleral buckle, even in eyes without retinal detachment.

How to repair a penetrating aorta?

Penetrating injuries to the thoracic aorta are usually treated with urgent surgical repair via an anterolateral thoracotomy. Endovascular repair with stent grafts may be possible for penetrating injuries in selected patients (see TAI section).

What is the most common mechanism of upper extremity vascular injury?

Penetrating trauma is the most common mechanism in upper extremity vascular injury. A penetrating mechanism of injury in military series is greater than 90% routinely, and consists of explosive shrapnel and high-velocity gunshot wounds.

How does high velocity trauma affect cerebrovascular injury?

High-velocity penetrating trauma can induce cerebrovascular injury-based predominantly on three underlying mechanisms: (1) direct soft tissue injury, (2) shock wave effects, and (3) thermal injury. Direct soft tissue injury occurs due to direct contact with the penetrating object, such as when a bullet passes through blood vessels, or by the creation of bony fracture fragments, which can act as secondary projectiles ( Moeng and Boffard, 2002; Steenburg et al., 2010 ). Shock wave effects result from the dissipation of kinetic energy into the soft tissues surrounding the penetrating trajectory, as well as the associated cavitation. Thermal injury to blood vessels can be caused by the intrinsically high temperatures of many projectiles.

What causes a thoracic injury to be punctured?

Most penetrating thoracic injuries are due to missile or knife wounds, but the intrathoracic organs are occasionally punctured by a bony fragment resulting from nonpenetrating trauma.

How does trauma affect your body?

Why do muscles contract during trauma?

Muscle contractions protect the physical body. Trauma causes very deep muscle contractions designed to protect the body from harm or possible death during a traumatic episode. The contraction in these muscles must be released to restore the body back to its relaxed state.

Why does overemphasis affect body sensitivity?

Overemphasis on thought distorts body sensitivity. Due to an overemphasis on the mind, the result of social and politically ingrained opinions, programming, and stigma, we have deadened this shaking mechanism so that it no longer reduces the muscular tension, causing us to continue to carry it in our bodies long after the trauma is over.

How does PTSD occur?

PTSD is caused by the lack of release of the high excitement or anxiety (biochemical energy) that was generated at the time of the traumatic event. The body continues to seek a discharge from this overstimulation, so the brain unconsciously reproduces situations similar to the original trauma. This is the mind’s attempt to replay the traumatic scenario so that that the energy can be discharged, in the hope that the victim will now become the survivor. The most common example of this is when abused children enter into abusive relationships as adults.

What is the term for the continuation of disturbing thoughts, emotions, and feelings that persist even after the trauma is over?

PTSD is the term used to explain the continuation of disturbing thoughts, emotions, and feelings that persist even after the trauma is over.

What happens if you don't fight or flee?

If you did not have the opportunity to fight or flee, or process the trauma, it is likely you froze and became stuck. Trauma side effects/symptoms are signs of a deregulated nervous system, and this is why natural healing is very useful and a necessary tool in trauma recovery. Written by Erin Paterson.

Why does the body store memories?

Because the experience is emotionally and physiologically overwhelming, the body stores the memories, thoughts, and emotions of the trauma in order to process them at a later date. The high chemical charge left in the body after trauma continually seeks to discharge.

Assessment includes x-rays, CT scans, and MRI. Treatment involves surgery to repair damaged structures and remove foreign objects.

How much mortality is associated with abdominal trauma?

The literature reveals mortality rates from 0-100%. The lowest mortality is in patients who sustain just a superficial injury to the abdominal wall but if the injury penetrated the peritoneum and is associated with hypotension, acidosis, and hypothermia, the mortality rates are more than 50%. The mortality is greatest in those who suffer a concomitant vascular injury of the abdominal vessels. When the patient is brought promptly to a trauma center, a 5% mortality rate can be expected. The majority of deaths occur within the first 24 hours of injury. Risk factors that predict mortality include female gender, the presence of shock on arrival, delay in treatment and associated head injury. Firearms are usually associated with a much higher morbidity and mortality compared to knife wounds. [17][18][19](Level V)

What is the most common cause of abdominal trauma?

Penetrating abdominal trauma is seen in many countries. The most common cause is a stab or gunshot. The most common organs injured are the small bowel (50%), large bowel (40%), liver (30%), and intra-abdominal vascular (25%). When the injury is close range, there is more kinetic energy than those injuries sustained from a distance. Even though most gunshot wounds typically have a linear projection, the high-energy wounds are associated with unpredictable injuries. There may also be secondary missile injuries from bone or bullet fragments. Stab wounds that penetrate the abdominal wall are difficult to assess. Occult injuries can be missed, resulting in delayed complications that can add to the morbidity.[1][2][3]

The most common cause is a stab or gunshot. The most common organs injured are the small bowel (50%), large bowel (40%), liver (30%), and intra-abdominal vascular (25%).

How does kinetic energy affect a projectile?

As a projectile passes through tissue, it decelerates and transfers kinetic energy to the tissue. Increased velocity causes more damage than mass. Kinetic energy increases with the square of the velocity.

How long does it take for a trauma patient to fall off?

Although some medical professionals in trauma and emergency medicine counter that there is insufficient evidence that results for a patient involved in trauma fall off after precisely 60 minutes, the principle remains the same: Rapid intervention can make all the difference in patient morbidity and mortality. And in a 2015 editorial in Injury: International Journal of the Care of the Injured, Rogers and colleagues stated: "There is an aspect to trauma care that is very time dependent."

When caring for a patient who's experienced penetrating trauma, hemorrhage control, either?

When caring for a patient who's experienced penetrating trauma, hemorrhage control, either externally by applying pressure or tourniquet, or surgical control is the next order of business after controlling the patient's air and ensuring adequate oxygen delivery. This is often the case even when a concomitant devastating neurological injury is present.

What is the importance of a paper clip in trauma?

Paper clips at the puncture site aid in matching up possible organ involvement on plain films. When available, a focused assessment with sonography in trauma (FAST) scan is an invaluable adjunct. Mapping the path of the bullet or knife and, by inference, the injured organs, forms the basis for timing and type of intervention.

Does hemorrhage control require immediate blood transfusion?

Is IV insertion anxiety normal?

Dr. Turay says that anxiety during IV insertion in high-stakes scenarios is normal. He encourages trauma providers to sharpen IV access skills, remembering that the intraosseous route is equally effective and relatively easier to attain in patients with profound shock.

Is CPR helpful after a heart attack?

Although CPR is a common tool, especially in the field, if the person doesn't have a pulse after penetrating trauma, CPR is not helpful. Unlike a heart attack or a choking incident, the heartbeat's cessation is due to blood loss, rendering this resuscitative method ineffective.

Can you touch an impaled object?

Dr. Turay recommends not touching or removing an impaled object, as it could worsen the injury. Also, he explains it's impossible to know what the object may touch inside the patient's body, perhaps compressing a vessel enough to prevent bleeding out. He suggests waiting for a surgeon to address it, as interference may worsen the injury. Trauma professionals may help the patient, however, with wound packing or a tourniquet for hemorrhage control.
