What is included in the evaluation of penetrating trauma to the torso?
Children with penetrating trauma to the torso require careful evaluation of the chest, abdomen, pelvis, and genital structures for system-specific injuries that may contribute to rapid decompensation and influence the order of emergent resuscitation.
How are penetrating injuries treated?
The patient is treated with intravenous fluids and/or blood. Surgery is often required; impaled objects are secured in place so that they do not move and they should only be removed in an operating room.
How do you stabilize penetrating injury?
Expose the patient to locate the origin of bleeding, and bandage the site of penetration. If bandaging does not adequately control bleeding, place manual pressure on the site of penetration and the local pressure point. This will slow down blood loss until the patient receives surgical intervention in the hospital.

What qualifies as penetrating trauma?
Penetrating trauma is an injury caused by a foreign object piercing the skin, which damages the underlying tissues and results in an open wound. The most common causes of such trauma are gunshots, explosive devices, and stab wounds.
Should you immobilize penetrating trauma wounds?
We recommend that spine immobilization not be used routinely for adult patients with penetrating trauma, as it is associated with increased mortality and has no benefit in preventing neurologic deterioration (Table 4).
Should you remove a penetrating 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.
What are the two most common injuries caused by penetrating chest trauma?
Hemothorax, pneumothorax, and a combination of these two injuries are the most common fatal complications of penetrating and blunt chest traumas.
Why must you seal an open chest wound?
Since air can pass through a dressing, you must seal an open chest wound to stop air from entering the chest and collapsing the lung.

What causes retinal detachment in children?
Penetrating ocular trauma. Penetrating injury is an uncommon cause of retinal detachment in childhood and may rarely follow inadvertent perforation of the globe at strabismus surgery. More common causes include accidental sharp penetrating injuries.
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.
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.
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 penetrating trauma?
Penetrating trauma involving the ureter occurs in approximately 4% of patients and is most often caused by a stab or gunshot wound.

The intestines are at risk of perforation with concomitant fecal matter complicating penetration. Penetrating abdominal trauma may cause hypovolemic shock and peritonitis. Penetration may diminish bowel sounds due to bleeding, infection, and irritation, and injuries to arteries may cause bruits.
What is the standard management of penetrating abdominal trauma?
The standard management of penetrating abdominal trauma is a laparotomy. A greater understanding of mechanisms of injury and improved imaging has resulted in conservative operative strategies in some cases.
What determines the severity of an abdominal injury?
The characteristics of the damaged tissue determine the severity of the injury: the denser the tissue, the greater the amount of energy transmitted to it. History and Physical. Penetrating abdominal trauma is due to stabbings, ballistic injuries, and industrial accidents.
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]
What is the treatment for penetrating trauma?
Assessment includes x-rays, CT scans, and MRI. Treatment involves surgery to repair damaged structures and remove foreign objects.

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%).
What are the first steps of trauma evaluation?
Early recognition of trauma to the chest is a priority. The first 3 steps of trauma evaluation involve evaluation, recognition, and intervention of potential injuries to “the box.” Following a routine method of TRAUMA PROTOCOL evaluation reduces missed injuries. Injuries to the heart and lungs are usually serious, and early diagnosis is vital since they have the highest mortality if missed. Injuries to other thoracic structures also need to be considered; the ribs, clavicle, trachea, bronchi, esophagus, and large vessels, including the aorta and veins, need to be evaluated in the secondary and tertiary survey.
When evaluating penetrating trauma due to missiles, a general rule of thumb to account for all possible?
When evaluating penetrating trauma due to missiles, a general rule of thumb to account for all possible injuries is that "wounds plus retained missiles" should be an even number.

[3][4]Gunshot and stabbing account for 10% and 9.5% of penetrating chest injuries in the United States. This incidence changes worldwide, and it is as high as 95% in countries engaged in war. [5][6][7][8][9][10]
How does pain control affect mortality?
Pain control greatly affects mortality and morbidity in patients with chest trauma.[23] Pain leads to splinting, which worsens or prevents healing. In many cases, the inability to cough leads to the collection of secretions, eventually leading to pneumonia. Early analgesia should be considered to decrease splinting. In the acute setting, IV push doses of short-acting opioids should be used. [24]
Is chest trauma the second most common traumatic injury?

Trauma to the chest is also associated with the highest mortality; in some studies, up to 60% depending on the mechanism of injury. This activity describes the cause, pathophysiology, and presentation of penetrating chest trauma and highlights the role of the interprofessional team in its management.
Is chest trauma more common than blunt trauma?
Chest trauma has quickly risen to be the second most common traumatic injury in non-intentional trauma.[1] Trauma to the chest is also associated with the highest mortality; in some studies, up to 60% depending on the mechanism of injury.[2] While penetrating chest trauma is less common than blunt trauma, it can be more deadly. Quick thinking and early interventions are key factors for evaluations, management, and survival.
Is chest trauma life threatening?
Chest trauma can be a result of penetrating or blunt trauma. While blunt trauma is more common, penetrating trauma can be acutely life-threatening. It is important to know the mechanism of injury as management may vary. Additionally, the directionality of penetration will dictate the investigation and intervention. Depending on the penetrating trauma, immediate operative intervention may be needed, making early diagnosis integral to survival. The penetrating injury should also be taken into consideration; for example, stab versus missile injury to the chest can result in different patterns of injury. Gunshot and stabbing account for 10% and 9.5% of penetrating chest injuries, making these the most common etiology of penetrating trauma. [3]
