The validity of the use of ultrasonography in the diagnosis of spontaneous and traumatic pneumothorax. Perera P, Mailhot T, Riley D, Mandavia D. The RUSH exam: Rapid Ultrasound in SHock in the evaluation of the critically lll. British Thoracic Society guidelines on respiratory aspects of fitness for diving. The first rib is often fractured posteriorly (black arrows). Tension pneumothorax during general anaesthesia is a rare but possibly deleterious event, especially where predisposing factors are absent or unknown, making diagnosis even challenging. Obstruction can occur at the level of the great vessels or the heart itself. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. These additional signs indicate hyperexpansion of the hemithorax: In the rare instance of bilateral tension pneumothoraces, there may be no cardiomediastinal shift 6,7. [8][28][29], If the patient is hemodynamically unstable and clinical suspicion is high for pneumothorax, immediate needle decompression must be performed without delay. Leigh-Smith S, Harris T. Tension pneumothorax--time for a re-think?. Rebecca Bascom, MD, MPH Professor of Medicine, Department of Medicine, Division of Pulmonary, Allergy, and Critical Care Medicine, Pennsylvania State College of Medicine, Milton S Hershey Medical Center; Graduate Faculty Member, Pennsylvania State University College of Medicine and The Huck Institutes of the Life Sciences [QxMD MEDLINE Link]. [39]In another study, patients with procedure-related tension pneumothorax had better outcomescompared to pneumothoraces occurring in the ITU due to barotrauma.[40]. 2005 Dec. 44 (12):1538-41. Positive pressure ventilation should be avoided initially, as it will increase the tension pneumothorax's size. Marquette CH, Marx A, Leroy S, Vaniet F, Ramon P, Caussade S, et al. However, tension pneumothorax is typically symptomatic, and its features are more impressive than spontaneous pneumothorax. If patients who are mechanically ventilated are difficult to ventilate during resuscitation, high peak airway pressures are clues to pneumothorax. Crit Care. 1989 Jun. 50 (6):754-8. An alternative mechanism is blunt thoracic trauma, where the increased alveolar pressure can cause the alveoli to rupture, resulting in the air entering the pleural cavity.[8]. The rate of iatrogenic pneumothoraces is increasing in US hospitals as intensive care modalities have increasingly become dependent on positive pressure ventilation and central venous catheters. Jalota Sahota R, Sayad E. Tension Pneumothorax. Huang TW, Lee SC, Cheng YL, Tzao C, Hsu HH, Chang H, Chen JC. Fluorescein-enhanced autofluorescence thoracoscopy in patients with primary spontaneous pneumothorax and normal subjects. 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]. Note the right-sided pneumothorax induced by the incorrectly positioned small-bowel feeding tube in the right-sided bronchial tree. Plewa MC, Ledrick D, Sferra JJ. 2012 Mar. In the case of iatrogenic or tension pneumothoraces in the hospital, this is usually in the ITU settings, the operating room, or a procedure suite. Radiograph showing subcutaneous emphysema and pneumothorax. 255 (3):440-5. Hearnshaw SA, Oppong K, Jaques B, Thompson NP. Pneumothorax and pregnancy. [QxMD MEDLINE Link]. Chest. The thorax may also be hyperresonant; jugular venous distention and tachycardia may be present. Atraumatic pneumothoraces are further divided into primary (unknown etiology) and secondary (patient with an underlyingpulmonary disease). Chest. [QxMD MEDLINE Link]. 35 (2):144-5. Martin M, Satterly S, Inaba K, Blair K. Does needle thoracostomy provide adequate and effective decompression of tension pneumothorax? 7. Clinical Presentation of Patients With Tension Pneumothorax: A Systematic Review. Abdominal distention may occur from increased pressure in the thoracic cavity producing caudal deviation of the diaphragm and from secondary pneumoperitoneum produced as air dissects across the diaphragm through the pores of Kohn. [QxMD MEDLINE Link]. J Trauma. 10 (6):1372-9. 2007 Sep. 44 (9):588-93. British Thoracic Society Fitness to Dive Group, Subgroup of the British Thoracic Society Standards of Care Committee. [QxMD MEDLINE Link]. Hypotension & Inspiration: Causes & Reasons - Symptoma Symptoms typically include sudden onset of sharp, one-sided chest pain and shortness of breath. Tension pneumothorax. [8], Tension pneumothorax is common in ITU-ventilated patients. 2003 Jan. 58 (1):3-13. 94 (3):512-3; table of contents. Advertisement Cambridge University Press. POCUS has sensitivity and specificity ranging from 90-100% for detecting pneumothorax. 9 (1):[QxMD MEDLINE Link]. Pneumothorax - Pulmonary Disorders - MSD Manual Professional Edition Ultrasound findings includethe absence of lung sliding and the presence of a lung point. This is a life-threatening emergency that needs urgent management. When mediastinal shifts accompany it, it is called a tension pneumothorax. Administration of 100% supplemental oxygen can help reduce the size of the pneumothorax bydecreasing the alveolar nitrogen partial pressure. Image courtesy S.Bhimji MD, left sided tension pneumothorax. Ann Thorac Surg. [QxMD MEDLINE Link]. Lippincott Williams & Wilkins. However, tension pneumothorax can cause severe hypotension, and open pneumothorax can compromise ventilation. Tension pneumothoraces occur when intrapleural air accumulates progressively with hemodynamic compromise 10. J Ultrasound Med. If you log out, you will be required to enter your username and password the next time you visit. Tension pneumothorax is a potentially life-threatening condition that medical professionals must treat as a medical emergency. In one series, acute onset of chest pain and shortness of breath were present in all patients in one series; typically, both symptoms are present in 64-85% of patients. Patients with high peak inspiratory pressure are at greater risk of tension pneumothorax. How emergency physicians choose chest tube size for traumatic pneumothorax or hemothorax: a comparison between 28Fr and smaller tube. Contralateral recurrence of primary spontaneous pneumothorax. 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. 8. Arch Surg. 6th ed. Am J Respir Crit Care Med. Oda R, Okuda K, Yamada T, Yukiue H, Fukai I, Kawano O, et al. Prevalence of tension pneumothorax in fatally wounded combat casualties. 1989 Dec. 96 (6):1302-6. Tension pneumothorax is an uncommon condition with a malignant course that might result in death if left untreated. Rapid detection of pneumothorax by ultrasonography in patients with multiple trauma. Once the patient is stabilized, this condition is managed by an interdisciplinary team, and input from each member is critical for successful patient outcomes. Clinical manifestations of tension pneumothorax: protocol for a systematic review and meta-analysis. 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 Although historic emphasis has been placed on tracheal deviation in the setting of tension pneumothorax, tracheal deviation is a relatively late finding caused by midline shift. Unlike the obvious patient presentations oftentimes used in medical training courses to describe a tension pneumothorax, actual case reports include descriptions of the diagnosis of the condition being missed or delayed because of subtle presentations that do not always present with the classically described clinical findings of this condition or the complexity of the patient with critical illness or injury. [37][38], Ventilator-related tension pneumothorax has been found to have dire outcomes and result in death more frequently. In a supine patient, the examiner should lower themselves to be on a level with the patient. Pneumothorax in the ICU: patient outcomes and prognostic factors. Agitation with tachypnoea. Emerg Med Pract. 1. This activity reviews the presentation of tension and traumatic pneumothoraces, outlines evaluation and management strategies, and highlights the importance of early intervention and the role of the interprofessional team in evaluating and improving care for patients with this condition. Secondary pneumothoraces are often more likely to recur, with cystic fibrosis carrying the highest recurrence rates at 68-90%. Pneumothorax in cystic fibrosis. Acta Anaesthesiol Scand.
