What is the commonest organ injured in bomb blast?

Blast lung is the most common fatal injury among initial survivors. Explosions in confined spaces (mines, buildings, or large vehicles) and/or structural collapse are associated with greater morbidity and mortality.

What is the most common blast injury?

Which of the following is the most common cause of death from a blast injury?

The most common cause of death in a blast event is secondary blast injuries. These injuries are caused by flying debris generated by the explosion. Terrorists often add screws, nails, and other sharp objects to bombs to increase injuries.

What causes the most damage during an explosion?

The air blast shock wave is the primary damage mechanism in an explosion.

What blast injuries are seen almost exclusively in the hollow organs?

Primary blast injury occurs almost exclusively in gas-containing organs: the ear, the respiratory tract, and the GI tract. Other blast injuries include Secondary Blast Injuries: those injuries caused by flying debris caused by the blast.

BLAST INJURIES // Types, Clinical Presentations and Complications

Why do people open their mouths during an explosion?

Explosions create waves of increased pressure, followed by negative pressure, which can be extremely damaging to ears and internal organs. Keeping ones mouth open is said to equalize pressure, therefore reducing internal damage.

Which organs are most often damaged with penetrating trauma?

The intestines were most commonly impacted by penetrating trauma (70.1% of cases), followed by the liver and spleen (19.4% and 17.9%, respectively). The most common mode of injury in penetrating trauma cases was gunshot (85%) and stab wounds (15%).

What happens to the human body during an explosion?

High explosive blasts can cause skull fractures, fractured bones, head injuries, or any traumatic injury (open or closed injuries, chest, abdominal, pelvic injuries, amputations, spinal injuries, and any others). Structural collapse and entrapment can cause crush injuries and compartment syndrome.

Which abdominal organ would most likely be affected by the primary phase of a blast injury?

Gas-containing sections of the GI tract are most vulnerable to primary blast effect. This can cause immediate bowel perforation, hemorrhage (ranging from small petechiae to large hematomas), mesenteric shear injuries, solid organ lacerations, and testicular rupture.

What is the effect of bomb blast on human body?

Gas filled structures such as lungs, GI tract, and middle ear are most susceptible. Leads to “Blast Lung” (pulmonary barotrauma), TM rupture, abdominal hemorrhage, globe rupture, concussion, air embolism. Secondary – From flying debris and bomb fragments. Any part of the body may be affected.

What is the most common cause of death in blunt chest trauma?

The cause of the mortality and morbidity in blunt chest trauma is mostly due to delayed pulmonary complications.

What are the types of blast injuries a patient can suffer from?

Primary injuries (PBIs) are caused by the effect of transmitted blast waves on gas-containing structures; secondary injuries, by the impact of airborne debris; tertiary injury, by the transposition of the entire body because of blast wind or structural collapse; quaternary injuries, by exposure to explosive products ( ...

What is the main cause of human injury death during an earthquake?

Ground vibrations during an earthquake are seldom the direct cause of death or injury. Most earthquake-related injuries and deaths result from collapsing walls, flying glass, and falling objects caused by the ground shaking.

Which body part is the most frequently injured?

Hands and fingers are exposed to daily wear and tear.

What is the most popular injury?

1. Strains. Strains are by far the most common of all sports-related injuries simply because we use so many muscles and tendons when we exercise or play. These moving parts are all susceptible to stretching farther than they should, or moving in ways they shouldn't move, leaving them torn, damaged and in pain.

What are the 5 most common injuries?

What organ is the most common site of injury for gunshots to the abdomen?

The most common organs injured are the small and large bowel at 50% and 40%, respectively. Also, the liver and intraabdominal vasculature are oftentimes injured as well at 40% and 30% involvement, respectively.

Which is the commonest organ that ruptures in blunt abdominal trauma?

Blunt abdominal trauma

A direct blow from blunt trauma can lead to solid organ rupture and visceral damage causing haemorrhage, contamination with the visceral contents, peritonitis and associated pelvic injuries. The most common organs injured are the spleen, liver and small bowel.

What are the top 3 most commonly injured organs in the abdomen and why?

The spleen is the organ damaged most commonly, followed by the liver and a hollow viscus (typically the small intestine). Penetrating injuries may or may not penetrate the peritoneum and, even if they do, they may not cause organ injury.

What organ in the body can explode?

The body can carry without the spleen

Often times it is a wiser decision for a person to remove their spleen entirely before it bursts and causes internal bleeding.

What does it feel like to be in an explosion?

They feel a jolting sensation that is not like anything they've ever experienced before in their lives. It can be much more severe than that and produce unconsciousness and damage to the body. Some of that is related to other aspects of the explosion obviously.

How big of an explosion can a human survive?

The Hidden Dangers of Changes in Pressure

The human body can survive blasts of sudden pressure of 20-40 psi, but it's not the only thing receiving that pressure. The pressure radiates outward from the blast in all directions.

Which organ is least likely to be damaged in an accident?

In an accident, the most affected internal organs are the spleen, kidneys, and liver. However, the urinary bladder (a hollow muscular organ used as a reservoir of urine) is one such organ that is usually the least affected in an automobile accident.

What is the most common body area affected in trauma that result in death?

Brain injury is still the leading cause of death after multiple trauma. Especially early deaths (up to 24 hours) and first week deaths are more often due to brain injury [13]. The second frequent cause of death is exsanguination mainly due to thoracic or abdominal injuries.

What organ is least often injured in blunt abdominal trauma?

The most common abdominal injuries are blunt and penetrating, and commonly injured organs are the spleen, bowels, stomach, and liver, with the least-frequently injured organs being the diaphragm and kidneys [14].
