Occult tension pneumothorax discovered following imaging for adult trauma patients in the modern major trauma system: a multicentre observational study. BMJ Mil Health 2024; 170:123-129. [PMID: 35584853 DOI: 10.1136/bmjmilitary-2022-002126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 05/08/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Tension pneumothorax following trauma is a life-threatening emergency and radiological investigation is normally discouraged prior to treatment in traditional trauma doctrines such as ATLS. Some trauma patients may be physiologically stable enough for diagnostic imaging and occult tension pneumothorax is discovered radiologically. We assessed the outcomes of these patients and compared them with those with clinical diagnosis of tension pneumothorax prior to imaging. METHODS A multicentre civilian-military collaborative network of six major trauma centres in the UK collected observational data from adult patients who had a diagnosis of traumatic tension pneumothorax during a 33-month period. Patients were divided into 'radiological' (diagnosis following CT/CXR) or 'clinical' (no prior CT/CXR) groups. The effect of radiological diagnosis on survival was analysed using multivariable logistic regression that included the covariates of age, gender, comorbidities and Injury Severity Score. RESULTS There were 133 patients, with a median age of 41 (IQR 24-61); 108 (81%) were male. Survivors included 49 of 59 (83%) in the radiological group and 59 of 74 (80%) in the clinical group (p=0.487). Multivariable logistic regression showed no significant association between radiological diagnosis and survival (OR 2.40, 95% CI 0.80 to 7.95; p=0.130). There was no significant difference in mortality between the groups. CONCLUSION Radiological imaging may be appropriate for selected trauma patients at risk of tension pneumothorax if they are considered haemodynamically stable. Trauma patients may be physiologically stable enough for radiological imaging but have occult tension pneumothorax because they did not have the typical clinical presentation. The historical dogma of the 'forbidden scan' no longer applies to such patients.

Diagnostic imaging in pediatric polytrauma management. Radiol Med 2014; 120:33-49. [PMID: 25376101 DOI: 10.1007/s11547-014-0469-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2014] [Accepted: 10/29/2014] [Indexed: 01/20/2023]
Abstract
Trauma is the cause of over 45% of deaths in children aged 1 to 14 years. Since multiple injuries are common among children, the emergency physician has to assess all the organs of a high-energy injured child, independent of mechanism of the trauma. Even if the principles of polytrauma management are identical both in children and in adults, the optimal pediatric patient care requires a specific understanding of some important anatomical, physiological, and psychological differences that play a significant role in the assessment and management of a pediatric patient. Emergency Radiology already plays a crucial role in the diagnostic process of a polytraumatized child according to the primary survey, through the use of multiple imaging modalities. Radiological and Ultrasound examinations play a basic role in the hemodynamically unstable patients. In the hemodynamically stable patients whole-body CT scanning is the most immediate radiological procedure that allows the examination of all the body parts of a polytraumatized child, reducing the number of minor injuries that might otherwise be neglected.

Clinical manifestations of tension pneumothorax: protocol for a systematic review and meta-analysis. Syst Rev 2014; 3:3. [PMID: 24387082 PMCID: PMC3880980 DOI: 10.1186/2046-4053-3-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2013] [Accepted: 12/23/2013] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Although health care providers utilize classically described signs and symptoms to diagnose tension pneumothorax, available literature sources differ in their descriptions of its clinical manifestations. Moreover, while the clinical manifestations of tension pneumothorax have been suggested to differ among subjects of varying respiratory status, it remains unknown if these differences are supported by clinical evidence. Thus, the primary objective of this study is to systematically describe and contrast the clinical manifestations of tension pneumothorax among patients receiving positive pressure ventilation versus those who are breathing unassisted. METHODS/DESIGN We will search electronic bibliographic databases (MEDLINE, PubMed, EMBASE, and the Cochrane Database of Systematic Reviews) and clinical trial registries from their first available date as well as personal files, identified review articles, and included article bibliographies. Two investigators will independently screen identified article titles and abstracts and select observational (cohort, case-control, and cross-sectional) studies and case reports and series that report original data on clinical manifestations of tension pneumothorax. These investigators will also independently assess risk of bias and extract data. Identified data on the clinical manifestations of tension pneumothorax will be stratified according to whether adult or pediatric study patients were receiving positive pressure ventilation or were breathing unassisted, as well as whether the two investigators independently agreed that the clinical condition of the study patient(s) aligned with a previously published tension pneumothorax working definition. These data will then be summarized using a formal narrative synthesis alongside a meta-analysis of observational studies and then case reports and series where possible. Pooled or combined estimates of the occurrence rate of clinical manifestations will be calculated using random effects models (for observational studies) and generalized estimating equations adjusted for reported potential confounding factors (for case reports and series). DISCUSSION This study will compile the world literature on tension pneumothorax and provide the first systematic description of the clinical manifestations of the disorder according to presenting patient respiratory status. It will also demonstrate a series of methods that may be used to address difficulties likely to be encountered during the conduct of a meta-analysis of data contained in published case reports and series. PROSPERO registration number: CRD42013005826.

Abstract
The pleural space is a potential space under normal physiologic circumstances. It envelops the lung, the mediastinum, the diaphragm and the chest wall. A thin film of pleural fluid provides lubrication for the two pleural layers; only 2-10 ml of pleural fluid is present in healthy people. For the purposes of this review, pleural abnormalities will be divided into pleural effusion, pneumothorax, and pleural calcification.

Abstract
Total intrathoracic stomach creating pulmonary and hemodynamic compromise is a rare life-threatening complication in patients with hiatal hernia. The presentation and clinical course of this condition are discussed. Physicians should consider this entity in patients presenting with apparent tension pneumothorax without history or other evidence of trauma or positive pressure ventilation who do not respond to standard interventions.
