A penetrating injury involving an impaled object, such as a knife, represents severe trauma requiring an immediate and specific emergency response. This type of wound creates a pathway into the body, potentially damaging soft tissue, organs, and major blood vessels. Understanding the correct initial actions can significantly impact the outcome and the injured person’s chances of survival. Knowing how to manage the object and the wound before medical professionals arrive is paramount.
The Critical Decision: Leaving the Object Embedded
The definitive answer to managing any impaled object is to never remove it in a pre-hospital setting. This rule is grounded in the object’s function as a temporary mechanical seal. By remaining lodged, the object physically presses against damaged blood vessels, creating a tamponade effect that slows or stops internal and external bleeding.
Removing the object eliminates this pressure, which can lead to rapid and catastrophic hemorrhage, known as exsanguination. The initial trauma may have severed a major artery or vein, and the presence of the knife is the only thing preventing immediate blood loss. Once the object is pulled out, the severed vessel is free to bleed uncontrollably into the body cavity.
Furthermore, the knife’s path through the body is unknown, and even medical professionals cannot be certain of its exact location without imaging. Any movement of the object, especially during removal, risks severing adjacent structures like nerves, muscles, or additional blood vessels.
The object’s presence is often temporarily sustaining life by plugging the wound. For instance, in deep chest or abdominal wounds, the object may be compressing a major vessel or an organ like the liver, and its removal would release a torrent of blood. Therefore, the immediate focus is on maintaining the status quo until specialized trauma care can be provided.
Stabilizing the Wound and the Impaled Object
Once the decision is made to leave the object in place, the next step involves stabilizing it to prevent any movement that could cause further internal damage. Movement of the object is the primary risk factor for worsening the injury, as even slight shifts can tear tissue or dislodge clots. The object must be secured in its current position to minimize this risk during transport or while waiting for help.
To achieve stabilization, bulky dressings are used to pad and surround the knife where it enters the body. Clean cloths, gauze, or even clean clothing can be folded and placed around the entry site to create a secure barrier. These materials should be layered and packed gently but firmly around the object on all sides, ensuring the knife itself does not move.
The dressings are then secured with tape or a bandage wrapped loosely around the object and the body. Care must be taken not to apply any direct pressure onto the object itself. Pressure should only be applied to the surrounding tissue to control any superficial bleeding around the edges of the wound. The injured person should also be kept as still as possible to limit muscle contraction or body shifts.
Transitioning to Professional Medical Care
Immediate activation of emergency medical services is the first step once the object has been stabilized. The object’s removal is a complex surgical procedure that must be performed only in a controlled environment, typically an operating room, by a trauma surgeon. This environment allows for immediate access to blood transfusions, advanced monitoring equipment, and surgical instruments necessary to repair the internal damage.
In the operating room, the surgical team can precisely control the bleeding that is expected to occur upon removal. They can directly visualize the damaged structures, clamp or ligate severed blood vessels, and repair injured organs. Attempting to remove the object outside of this controlled setting makes managing the inevitable hemorrhage virtually impossible and drastically increases the risk of death.
While awaiting professional help, continuous monitoring of the injured person is necessary. Watch for signs of shock, such as confusion, rapid heart rate, or pale, clammy skin, which indicate significant internal blood loss. Keep the person calm, reassure them, and maintain the stabilization of the object until trained paramedics can take over and prepare the patient for safe transport to a trauma center.
