BackgroundPneumothorax (PTX) is defined as air in the pleural space and is classified as spontaneous or nonspontaneous (traumatic). Traumatic PTX is a common pathology identified in the emergency department. Traditional management calls for chest x-ray (CXR) diagnosis and large-bore tube thoracostomy, although recent literature supports the efficacy of lung ultrasound (US) and more conservative approaches. There is a paucity of cohesive literature on how to best manage the traumatic PTX.Objective Of The ReviewThis review aimed to describe current practices and future directions of traumatic PTX management.DiscussionLung US has proven to be a potentially more useful tool in the detection of PTX in the trauma bay compared with CXR, and has the potential to become the new gold standard for diagnosing traumatic PTX. Computed tomography remains the ultimate gold standard, although in the setting of trauma, its utility lies more in confirming the presence and measuring the size of a PTX. The traditional mantra calling for large-bore chest tubes as first-line approaches to traumatic PTX is challenged by recent literature demonstrating pigtail catheters as equally efficacious alternatives. In patients with small or occult PTXs, even observation may be reasonable.ConclusionsModern management of the traumatic PTX is shifting toward use of US for diagnosis and more conservative management practices (smaller catheters or observation). Ultimately, this shift is favorable in reducing length of stay, development of complications, and pain in the trauma patient.Copyright © 2021 Elsevier Ltd. All rights reserved.
