Delay in diagnosis and management is associated with a poor prognosis. Rapid Ultrasound for Shock and Hypotension (RUSH) Clinical manifestations of tension pneumothorax: protocol for a The first rib is often fractured posteriorly (black arrows). The initial assessment involves a chest radiograph (CXR) to confirm the diagnosis.[21]. Occult pneumomediastinum in blunt chest trauma: clinical significance. Hypotension worsens with inspiration due to increased intrathoracic pressure. Smoking and the increased risk of contracting spontaneous pneumothorax. [QxMD MEDLINE Link]. Lippincott Williams & Wilkins. Hsu CW, Sun SF, Lee DL, Chu KA, Lin HS. Obstruction can occur at the level of the great vessels or the heart itself. The occult pneumothorax: what have we learned?. Tension Pneumothorax Tension pneumothorax is the progressive built-up of air within the pleural space. Arch Surg. Terada T, Nishimura T, Uchida K, Hagawa N, Esaki M, Mizobata Y. It is difficult to determine the actual incidence of tension pneumothorax as by the time trauma patients are transported to trauma centers, they have already received decompressive needle thoracotomies. Simple aspiration versus chest-tube insertion in the management of primary spontaneous pneumothorax: a systematic review. Management of spontaneous pneumothorax: an American College of Chest Physicians Delphi consensus statement. 3. In severe cases, or if the diagnosis was missed, patients could develop acuterespiratory failure and possibly cardiac arrest. Pneumothorax in the ICU: patient outcomes and prognostic factors. These are all life-threatening. A tension pneumothorax is caused by excessive pressure build up around the lung due to a breach in the lung surface which will admit air into the pleural cavity during inspiration but will not allow any air to escape during expiration. Positive pressure ventilation should be avoided initially, as it will increase the tension pneumothorax's size. Acad Emerg Med. The following specialties should be on board while managing such patients: Following a pneumothorax, patients must be educated to avoidair travel until complete resolution or for a minimum of two weeks after surgical intervention. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. Pleural cavity (or intrapleural) pressure is negative as compared to lung pressure and atmospheric pressure. 342 (12):868-74. 2012 Mar. Findings on lung auscultation also vary depending on the extent of the pneumothorax. Symptoms and Signs of Thoracic Trauma. Toffel M, Pin M, Ludwig C. [Thoracic Surgical Aspects of Seriously Injured Patients]. Pleuritic Chest Pain: Sorting Through the Differential Diagnosis Image courtesy S.Bhimji MD, left sided tension pneumothorax. 37 (3):180-2. Baumann MH, Strange C. Treatment of spontaneous pneumothorax: a more aggressive approach?. [Full Text]. Rarely, it is a complication of traumatic pneumothorax, when a chest wound acts as a one-way valve that traps increasing volumes of air in the pleural space during inspiration.
