Can Lead Poisoning Occur After A Gunshot?

This is a fairly common question from victims of gunshots and their families. As you know, bullets are routinely left in place unless they are superficial. It may cause more damage to try to extract one, especially if it has come to rest in a deep location. But is there danger in leaving the bullet alone?

One of the classic papers on this topic was published in 1982 by Erwin Thal at Parkland Hospital in Dallas. The paper recounted a series of 16 patients who had developed signs and symptoms of lead poisoning (plumbism) after a gunshot or shotgun injury. The common thread in these cases was that the injury involved a joint or bursa near a joint. In some cases the missile passed through the joint/bursa but came to rest nearby, and a synovial pseudocyst formed which included the piece of lead. The joint fluid bathing the projectile caused lead to leach into the circulation.

The patients in the Parkland paper developed symptoms anywhere from 3 days to 40 years after injury. As is the case with plumbism, symptoms were variable and nonspecific. Patients presented with abdominal pain, anemia, cognitive problems, renal dysfunction and seizures to name a few.

Bottom line: Any patient with a bullet or lead shot that is located in or near a joint or bursa should have the missile(s) promptly and surgically removed. Any lead that has come to rest within the GI tract (particularly the stomach) must be removed as well. If a patient presents with odd symptoms and has a history of a retained bullet, obtain a toxicology consult and begin a workup for lead poisoning. If levels are elevated, the missile must be extracted. Chelation therapy should be started preop because manipulation of the site may further increase lead levels. The missile and any stained tissues or pseudocyst must be removed in their entirety.

Dealing With Shotgun Wounds

Shotgun wounds are uncommon but potentially disabling or deadly. Here are some basics for dealing with them.

Most people only think about the shot that comes out of the shotgun shell and its effects. While this certainly causes a problem, this foreign body is only a part of it. And it can be challenging to pick them out surgically. However, there are two other foreign bodies that become an issue: the wad, and other material on or around the patient (clothing, pieces of a door, etc). 

Look at the diagram above on the left. The wad is a plastic cup that holds the shot and helps the exploding powder charge propel it out of the shell (see sample pictures on the right). If the shotgun is fired at relatively close range, the wad can enter the patient’s wound. It is usually found near the surface and is easily recognized. Be sure to look for it when removing clothing and dressings from your patient.

Any debris from the patient’s surroundings will end up deep to the wad. It is usually centrally located in the wound, and may penetrate as deep as the shot. I once found a piece of coat fabric in the middle of an abscess that formed months after the shooting.

Management of these wounds requires general anesthesia and patience. The soft tissue injury is always worse than it appears, and make take up to 3 days to fully declare itself. I recommend debriding all obviously devitalized tissue and then placing a negative pressure dressing (if possible) to help reduce tissue edema.

All easily found shot should be removed during the initial operation. Deeply embedded particles will either scar in place or migrate to the surface. If all dead tissue is removed, infection is not that common. Inspection of all vital structures, especially blood vessels, should be performed at that time. Remember, due to the velocity and force involved, arteries may appear completely normal on the outside but have significant intimal interruption.

The patient should return to the OR every other day until all tissue die-back has stopped. Final closure or reconstruction can be considered at that time.
