Definition

A puncture wound, often referred to as a stab wound or vulnus punctum, is a small open wound that occurs when a sharp instrument, such as a knife, nail, needle, or any other thing with a sharp edge, penetrates the skin. This type of injury may arise during activities involving sharp implements, such as working with tools, walking without appropriate footwear, or being punctured by a sharp object on the road. Puncture wounds can manifest on the epidermis, subcutaneous tissue, or even internal organs, beyond the superficial layers of the skin and perhaps concealing more severe injuries.

Puncture wounds commonly occur on the feet, particularly during the summer when many individuals opt not to wear footwear. While puncture wounds on the feet are common, they are generally not appropriately treated. Inadequate treatment of the wound may lead to the development of infection or other complications.

Proper management within 24 hours of getting a wound is crucial due to tiny particles or foreign objects beneath the skin's surface in the puncture wound. This is potentially hazardous to your body.

Causes

Puncture wounds are typically caused by sharp-edged objects such as glass, toothpicks, nails, needles, spikes, knives, or razors. Typically, an individual could experience a stab wound in the following circumstances:

• Walk barefoot and step on sharp objects that pierce your foot on the road
• Being bitten by an animal
• Impaling oneself on a sharp object
• Motor vehicle accident
• Injured by shattered glass
• Experience an incident of being stabbed or involved in a criminal offense

Puncture wounds may not always result in profuse bleeding for individuals affected. Nevertheless, the wounds that occur are susceptible to bacterial infection. This can occur if a rusty or unclean object punctures or penetrates the skin in this condition.

Risk factor

Recognizing the risk factors is crucial in preventing and getting the puncture wounds treated. Anyone is susceptible to experiencing this. Nevertheless, certain risk factors will impact the likelihood of getting a puncture wound in the future.

Several of these risk factors include:

• Work in tasks involving pointed or sharp instruments that could potentially cause puncture wounds
• Work in a job that allows you to go barefoot outside
• Engage in the construction of buildings or the operation of heavy machinery and sharp equipment

Symptoms

A puncture wound might penetrate the skin's surface or extend deep into it. If the stab wound is deep, it might affect tendons, muscles, ligaments, nerves, and blood vessels or even reach the bone.

Several symptoms and signs of puncture wounds include:

• Presence of bleeding
• Experiencing numbness or issues concerning movement in the area below the punctured body part
• Painful sensation

However, these symptoms might escalate even further if the wound is infected. Potential sources of infection in puncture wounds include animal bites, stabbings, traffic accidents, contaminated wounds, wounds in the leg region, and inadequately treated wounds.

Diagnosis

Diagnosing a puncture wound is established by evaluating the wounds and symptoms clinically, which involves medical interviews and physical examinations conducted by a doctor. Typically, a puncture wound can be recognized by the appearance of a distinctive wound in the affected area. Nevertheless, there are other diagnostic tests available that can assist the doctor in establishing a definitive diagnosis and identifying potential complications that may occur.

Some diagnostic tests can be conducted, including a complete blood count or a culture procedure in case of an infection. If a sharp object causes a limb injury that impairs mobility, it is also possible to have a diagnostic test such as an X-ray.

Before your consultation, it is advisable to inform your doctor if you have had a puncture wound previously. Providing details about the onset of symptoms will assist physicians in diagnosing and selecting the most effective treatment during the initial medical examination.

Management

The puncture wound has to be treated properly. Thorough cleansing of the wound is necessary, and close monitoring of the healing process is essential to prevent any undesirable complications that could arise.

Without delay, please proceed to the nearest healthcare facility, such as the emergency room, to promptly receive medical care. The doctor will ensure the wound is thoroughly cleansed and free of foreign objects within the wound site. The doctor could provide anesthetic medicine or a numbing agent to the area of the wound, ensuring that the patient does not experience any pain during the treatment. Once the area is numbed with anesthesia, the doctor will meticulously cleanse the inside or outside of the wound and closely observe the progress of wound healing.

The doctor will provide instructions to manage your wound at home:

• Keep the wound dressing dry
• Limit the movement of the wounded body part to provide support while you move
• Complete the recommended course of antibiotics
• Measure body temperature regularly
• Observe the wounded body part for any indications of infection, such as pain, inflammation, swelling, or fever
• Consult your doctor again if there are indications of infection

Complications

When an individual suffers from a puncture wound, the common complication that arises is infection. Wound-associated infections may potentially cause harms to the body. Superficial skin infections can form at the punctured area. Nevertheless, the infections can spread and involve the skeletal or joints structure, so the wound and patient's condition have to be attended carefully.

Superficial skin infections may develop between the second and fifth day following the puncture wound. Several clinical signs of infection that could be observed include:

• There is escalating pain that gets more severe
• Erythema in the surrounding area of the wound
• Swelling and a sensation of warmth in the wounded area accompanied with pus discharge
• Fever can also indicate the initiation of a process where an infection is spreading to the bloodstream

Common symptoms and signs of a puncture wound include bleeding, numbness in the surrounding area below the wound or movement problems, and pain. Infection may emerge in the puncture wound if the penetrated object is rusty or not clean, facilitating the entry of germs into the wound and leading to potential complications.

Prevention

Once you have identified several risk factors, the subsequent action is to fix the modifiable ones. Below are the recommended steps you can follow:

• Wear appropriate footwear before venturing outdoors
• Take extra care when engaging in activities using sharp objects that could penetrate your body
• Ensure that you adhere to your doctor's instructions regarding your medication regimen

Additionally, if you have not yet consulted a doctor, you should get checked thoroughly. If any underlying conditions or diseases are identified that may raise your susceptibility to a puncture wound, it is recommended to start treatment promptly to prevent the condition from deteriorating.

When to see a doctor?

If you have persistent symptoms on the wounded skin, along with signs of infection such as fever, increasing pain, or pus discharge from the puncture wound, you should seek consultation with a specialist surgeon or dermatologist. The doctor will conduct a comprehensive medical interview, perform a physical examination, and, if necessary, carry out additional diagnostic tests to establish a definitive diagnosis and prescribe the appropriate treatment.
