If multiple rib fractures occur along the midlateral (red arrows) or anterior chest wall (blue arrows), a flail chest (dotted black lines) may result, which may result in pneumothorax. As the pressure increases, it will cause the mediastinum to shift towards the contralateral side, contributing further to hypoxemia.

Tension pneumothorax is an uncommon condition with a malignant course that might result in death if left untreated. It can happen secondary to trauma (traumatic pneumothorax). [Full Text].

Connective Tissue Disease-Interstitial Lung Disease, Doctors Are Disappearing From Emergency Rooms as Hospitals Look to Cut Costs. Clin Oncol (R Coll Radiol). Methods by which these mechanisms may maintain arterial blood pressure during tension pneumothorax include: 1) incomplete transmission of ipsilateral pneumothorax-related pressure to the mediastinum and contralateral hemithorax; 2) maintenance of cardiac venous return through rising spontaneous respiratory effort resulting in increasingly In these cases, emergency medical technicians (EMTs), ED nurses, and providers have a role in recognizing this entity promptly and initiating early interventions. 29 (3):239-42. Penetrating chest wounds must be covered with an airtight occlusive bandage and clean plastic sheeting. Tracheal deviation is an inconsistent finding.

Pneumothoraces are classified as simple (no shift of mediastinal structures), tension (shift in mediastinal structures present), or open (air passing through an open chest wound). Chest. However, the risk of lung re-expanding quickly increases the risk of pulmonary edema. The initial assessment involves a chest radiograph (CXR) to confirm the diagnosis.[21]. If the patient is hemodynamically unstable and in acute respiratory failure, a bedside ultrasound should be performed to confirm the diagnosis if it is available for immediate use. This can be used as a bedside technique to detect pneumothorax, which may be useful in unstable patients. Melton LJ, Hepper NG, Offord KP. Assessment of pneumothorax resolution is usually done with serial chest X-rays. Curr Opin Pulm Med. What Can We Do? Baumann MH, Strange C, Heffner JE, Light R, Kirby TJ, Klein J, et al. Prevalence of tension pneumothorax in fatally wounded combat casualties. Tension pneumothorax is classically characterized by hypotension and hypoxia. Although tension pneumothorax may be a difficult diagnosis to make and may present with considerable variability in signs, respiratory distress and chest pain are generally accepted as being universally present, and tachycardia and ipsilateral air entry on auscultation are also common findings. Hernandez C, Shuler K, Hannan H, Sonyika C, Likourezos A, Marshall J. A pneumothorax is an abnormal collection of air in the pleural space between the lung and the chest wall. Acta Pathol Jpn.

Due to the valve effect air will be stuck inside the pleural space without any means of escape. Tschopp JM, Rami-Porta R, Noppen M, Astoul P. Management of spontaneous pneumothorax: state of the art. The presentation of patients with pneumothorax varies depending on the type of pneumothorax. Tachycardia. 1989 Jun. Hypoxemia also triggers pulmonary vasoconstriction and increases pulmonary vascular resistance. Pneumothorax can result in tension physiology as well though the hemodynamic compromise from this, when a patient is on mechanical ventilation, is usually quicker than with hemothorax. Tagami R, Moriya T, Kinoshita K, Tanjoh K. Bilateral tension pneumothorax related to acupuncture.

Schramel FM, Postmus PE, Vanderschueren RG. 9. In a minority of cases, a one-way valve is formed by an area of damaged tissue, and the amount of air in the space between chest wall and lungs increases; this is called a tension pneumothorax. In hypovolemic trauma patients with ongoing hemorrhage, the physical findings may lag behind the presentation of shock and cardiopulmonary collapse. The timely and accurate evaluation leadsto early interventions decreasing mortality and morbidity. The severely symptomatic patients will present with shortness of breath. Management of emergency department patients with primary spontaneous pneumothorax: needle aspiration or tube thoracostomy?. Cardiopulmonary imaging. Barrios C, Tran T, Malinoski D, Lekawa M, Dolich M, Lush S, et al. It is a life-threatening occurrence requiring both rapid recognition and prompt treatment to avoid a cardiorespiratory arrest. [1][2]It is a severe condition that results when air is trapped in the pleural space under positive pressure, displacing mediastinal structures and compromising cardiopulmonary function. These signs should be carefully observed by inspection. Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. 174 (1):26-30. 2012 Mar. Acupunct Med.

Thus, having personnel trained in emergency assessment of pneumothoraces and having an emergency kit for thoracotomies, intubation, and patient stabilization is essential. Pearls and Pitfalls in Emergency Radiology: Variants and Other Difficult Diagnoses. Iatrogenic pneumothorax is a traumatic pneumothorax that results from injury to the pleura, with air introduced into the pleural cavity secondary to a diagnostic or therapeutic medical intervention. This website also contains material copyrighted by 3rd parties. Eventually, impaired venous return results in cardiac arrest and death. J Thorac Cardiovasc Surg. With tension pneumothorax, patients will have signs of hemodynamic instability with hypotension and tachycardia. Cardiac tamponade can clinically mimic tension pneumothorax. Knowledge of necessary emergency thoracic decompression procedures is essential for all healthcare professionals. Causes of traumatic pneumothorax include the following: Iatrogenic (induced by a medical procedure). 2009 Jun. Symptoms of iatrogenic pneumothorax are similar to those of a spontaneous pneumothorax and depend on the age of the patient, the presence of underlying lung disease, and the extent of the pneumothorax. Computed tomography scan demonstrating secondary spontaneous pneumothorax (SSP) from radiation/chemotherapy for lymphoma. Thorax. Prevalence of tension pneumothorax in fatally wounded combat casualties. It is usually managed in the emergency department or the intensive care unit. 14G intravenous cannula) can be inserted, typically in the 2nd intercostal space in the midclavicular line, to gain valuable time, before a larger underwater drain can be inserted 1.

In addition to the sonographic features of pneumothorax, a RUSH exam (often performed in the setting of hemodynamic instability) the following features imply the presence of tension physiology 8: Treatment of a tension pneumothorax is one of the classic medical emergencies where life can be saved or lost on the basis of recognition and subsequent rapid decompression. At the time the article was last revised Ian Bickle had no recorded disclosures. Mary C Mancini, MD, PhD, MMM Smoking and the increased risk of contracting spontaneous pneumothorax. Anesthesiology. 2022 Apr. In a recent study, 95% of pneumothorax episodes were observed to be iatrogenic; of these, barotrauma secondary to mechanical ventilation resulted in 69.6% of cases, 41.1% of which were tension pneumothoraces. [QxMD MEDLINE Link]. The risk of pneumothorax is greater with failed access at the initial vein, a subclavian vein approach, and positive pressure ventilation. Johnson G. Traumatic pneumothorax: is a chest drain always necessary? Distended neck veins and tracheal deviation are also often present. Chest. When mediastinal shifts accompany it, it is called a tension pneumothorax.
