Background: Open Pneumothorax is a condition where large injury occurs in the chest wall into the thoracic cavity and the injury remains open, also known as sucking chest wound. Methods: We present a case of Open Pneumothorax patient in our health care unit in rural hospital area. Complimentary databases were collected from PubMed and Scholar Google. Case Illustration: A 20-year-old male presented to the emergency department with a penetrating thoracic injury caused by a sharp weapon. The patient exhibited signs of respiratory distress, diminished breath sounds, and a visible wound indicating an open pneumothorax condition. Discussion: Thoracic trauma remains a serious problem, although trauma-related injury occurs in many parts of the body, but one out of four patients die due to thoracic injury or its complications. Trauma can be categorized into two primary types: penetrating and blunt. Penetrating injuries, such as those caused by cutting or firearms, lead to the disruption of tissue integrity. Conclusion: In conclusion, thoracic trauma represents a critical medical challenge, accounting for a substantial proportion of trauma-related fatalities. The distinction between penetrating and blunt injuries is pivotal, with the latter, constituting most cases, being associated with various mechanisms such as falls, accidents, and occupational incident.
