S21.142

Clinical Causes: Accidental stabbing or puncture by sharp objects such as nails, glass, or metal pieces Falls onto pointed objects that pierce the chest wall Industrial or occupational injuries involving machinery or tools Animal bites or scratches causing puncture wounds in the chest area Assault with weapons involving stabbing motions

Key Symptoms: Localized pain at the injury site Visible puncture wound or injury mark on the chest wall Possible bleeding from the wound Swelling or redness around the puncture area Rarely, symptoms of infection such as warmth, pus, or fever if bacteria enter the wound Difficulty breathing might occur if swelling impairs chest wall movement, although this is less common without penetration into the thoracic cavity

Diagnosis Path: Diagnosis begins with a thorough physical examination of the chest wall to assess the injury. Medical professionals may order the following: - Imaging studies such as chest X-ray to detect foreign objects and exclude penetration into the thoracic cavity. - Ultrasound may be used to evaluate the extent of soft tissue damage. - Wound assessment to identify potential signs of infection or damage to underlying structures. - Tetanus status review and consideration of prophylactic antibiotics depending on the injury severity.

Treatment Protocols: Treatment focuses on managing the wound to prevent infection and remove the foreign body if necessary: - Proper wound cleaning and debridement to eliminate debris and bacteria. - Surgical removal of foreign bodies when visible or accessible. - Administration of tetanus prophylaxis based on vaccination history. - Use of antibiotics if there is a risk of infection. - Pain management with appropriate medications. - Monitoring for signs of complications such as infection or injury progression. - Follow-up care to ensure proper healing and to address any potential issues arising from the injury.
