What You'll Learn
Assessing the severity of the injury
Assessing the severity of a stab wound is a critical step in providing appropriate treatment. Here are some key factors to consider when evaluating the severity of a stab wound:
Location and Depth of the Wound
The anatomical location of the stab wound plays a crucial role in determining its severity. For instance, wounds to the abdomen are particularly concerning due to the potential damage to internal organs and the risk of internal bleeding. The depth of the wound is also important, as deeper wounds indicate a higher risk of organ damage and internal injuries.
Number and Characteristics of Wounds
It is important to identify all wounds present. Multiple stab wounds, especially those caused by intentional violence, may indicate a higher risk of associated injuries and complications. Additionally, consider the characteristics of the wound, such as whether there is something stuck in the wound, if there are slashes, and the direction and length of the wound. These factors can provide insights into the potential damage to underlying structures.
Bleeding and Hemorrhage Control
Assessing the severity of bleeding is vital. A severe wound typically exhibits steady and profuse bleeding or spurting blood, which indicates a potential arterial injury. Controlling hemorrhage is crucial to stabilize the patient and prevent further blood loss, which is one of the leading causes of death in stab wounds.
Diagnostic Imaging and Laboratory Tests
Diagnostic tools such as focused assessment with sonography (FAST) or diagnostic peritoneal lavage (DPL) can help determine the presence of internal bleeding. More advanced imaging techniques like computed tomography (CT) scans provide detailed information about the severity and location of the injury. Laboratory diagnostic studies, including hematocrit, white blood cell count, and liver function tests, also aid in evaluating the patient's condition and the effectiveness of treatment.
Vital Signs and Shock
Monitoring vital signs is essential when assessing the severity of a stab wound. Maintaining systolic blood pressure above 90mmHg is critical to prevent shock. Additionally, keeping the patient's core body temperature stable and promptly transporting them to a trauma center in severe cases are crucial aspects of managing stab wounds.
The assessment and treatment of stab wounds require a comprehensive approach that considers the unique characteristics of each injury and the patient's overall condition.

Packing the wound
Packing a wound is a critical skill to stop bleeding and protect the wound from outside contaminants that could cause infection. This is especially important in the case of stab wounds, which are a specific form of penetrating trauma to the skin that can result in internal and external injuries.
To pack a stab wound, the first step is to clean the wound thoroughly to remove blood, pus, crust, and other contaminants. This can be done by rinsing the area with a saline solution, taking care to gently clean any narrow spots or tunnels within the wound. It is important to work from the middle of the wound outwards to avoid introducing bacteria from the surrounding area. Once the wound is clean, it is time to prepare the packing materials.
The packing material used for a stab wound is typically sterile gauze, which is designed to absorb drainage and protect the wound. It is important to dampen the gauze slightly with saline solution before inserting it into the wound. The gauze should be carefully packed into the wound, ensuring that it is not soaked through, as this can hinder the healing process. The goal is to fill the wound cavity and provide a protective layer that will allow the wound to heal from the inside out.
After the wound has been packed with gauze, it is then covered with a dressing and secured with tape. It is important to ensure that the bandage is not too tight and that it allows for adequate circulation. The wound should be monitored regularly and the dressing changed once or twice a day, or as recommended by a medical professional. Antibiotic ointment can also be applied to the wound to help prevent infection.
In addition to packing the wound, it is crucial to address any other aspects of care, such as alleviating pain and stabilizing the patient until they can receive further medical attention. This may include interventions such as airway management, intravenous access, and control of haemorrhaging, depending on the severity and location of the wound. Overall, packing a stab wound is a critical step in the treatment process, helping to control bleeding, protect the wound, and promote healing.

Preventing infection
Stab wounds are a specific form of penetrating trauma to the skin caused by a knife or a similar pointed object. They can result in various internal and external injuries and are typically inflicted by low-velocity weapons. As a result, the damage is usually confined to the weapon's path, but the abdomen, chest, neck, and head are high-risk areas for life-threatening injuries due to the presence of vital organs, arteries, or large blood vessels.
Infection is a common concern in stab wounds, especially if caused by a dirty or contaminated object. Therefore, preventing infection is a crucial aspect of treating stab wounds, both as immediate first aid and in hospital settings. Here are some measures to prevent infection:
Immediate First Aid
If you are providing first aid to someone with a stab wound, it is essential to prioritize infection prevention. Here are some key steps:
- Put on disposable gloves if available. If not, use plastic bags or another protective barrier to reduce the risk of infection to yourself and the victim.
- Cover the wound with a sterile gauze pad or the cleanest cloth available to protect it from bacteria, dirt, or other contaminants that could lead to infection.
- If the wound is bleeding, place a clean cloth, bandage, or sterile gauze directly over it and apply firm, continuous pressure to control the bleeding.
- If there is a foreign object embedded in the wound, do not remove it, as this could cause further damage or uncontrolled bleeding. Instead, stabilize it by placing gauze or cloth around it to prevent movement.
- If possible, elevate the wounded limb above heart level to slow down bleeding, but do not elevate wounds on the chest, abdomen, or back, as this may interfere with breathing or exacerbate internal injuries.
- Call for emergency medical help immediately. While waiting for help, monitor the victim's breathing and consciousness.
Hospital Treatment
Once the patient reaches the hospital, medical professionals will continue to take measures to prevent infection:
- Doctors will clean the wound and assess the extent of the injury, including any damage to muscles, blood vessels, or organs.
- They may give the patient antibiotics to prevent infection, especially if the object that caused the wound may have been contaminated.
- The wound will be packed with gauze and covered with a dressing and tape to prevent contamination and infection.
- Surgical intervention may be required to repair damage and remove devitalized tissues, which can help reduce the risk of infection.
- Patients are typically advised to keep the wound clean and dry during the healing process to prevent infection.

Stabilising the patient
Stabilising a patient with a stab wound is a critical procedure that requires immediate attention to alleviate bleeding and pain. Here are the steps to stabilise a patient:
Assess the Situation and Protect Yourself
Put on disposable gloves or plastic bags to protect yourself and the victim from infection. Identify the severity and location of the wound(s). Check if there is something stuck in the wound, if there are multiple wounds, or if there are slashes. Determine the source of bleeding and its location on the body. Part the person's clothing to properly identify the wound(s) and try to find all wounds before starting treatment.
Address Severe Bleeding
If there is a severe wound with steady and profuse bleeding or spurting blood, address it immediately. Spurting blood indicates that an artery has been hit. In such cases, do not close the wound, as it is crucial to stop the bleeding first.
Pack the Wound
To prevent contamination and infection, pack the wound with gauze and cover it with a dressing and tape. This will help stop the bleeding and protect the wound until medical professionals can take over.
Monitor Vital Signs
Keep the patient's systolic pressure above 90mmHg and maintain their core body temperature. If the patient is going into shock, ensure prompt transport to a trauma center for further stabilisation and treatment.
Antibiotic Treatment
Apply antibiotic ointment to the wound when replacing the dressing to prevent infection.
