Wax DB, Leibowitz AB. 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. 2001 Feb. 50 (2):201-5.

[Full Text]. Thus, having personnel trained in emergency assessment of pneumothoraces and having an emergency kit for thoracotomies, intubation, and patient stabilization is essential. In PSP, chest often improves over the first 24 hours, even without resolution of the underlying air accumulation. McPherson JJ, Feigin DS, Bellamy RF.

Which of the follow assessment finding differentiates a tension pneumothorax from a simple pneumothorax?

The first-line responders when a patient develops a traumatic or tension pneumothorax vary depending on the situation and underlying etiology. 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. Blunt thoracic trauma patiens may have tracheal deviation and deformities of the chest wall may be observed. 2006 Mar. Whale C, Hallam C. Tension pneumothorax related to acupuncture. 2003 Jun.

[3], On examination, it is essential to assess for signs of respiratory distress, including increased respiratory rate, dyspnea, and retractions. 2009 Jun. 13 (3):209-10. The breach acts as a one-way valve. Despite descriptions of Valsalva maneuvers and increased intrathoracic pressures as inciting factors, spontaneous pneumothorax usually develops at rest. 28 (6):749-55. Note the right-sided pneumothorax induced by the incorrectly positioned small-bowel feeding tube in the right-sided bronchial tree. Moreover, central venous catheter insertion was responsible for 13.2%of cases. Martin M, Satterly S, Inaba K, Blair K. Does needle thoracostomy provide adequate and effective decompression of tension pneumothorax? [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. [QxMD MEDLINE Link]. Arch Surg. Chest. Hearnshaw SA, Oppong K, Jaques B, Thompson NP. That pressure gradient between the lung and pleural space prevents the lung from collapsing. Chemical pleurodesis is an alternative if the patient cannot tolerate mechanical pleurodesis. Advertisement [QxMD MEDLINE Link]. Rojas R, Wasserberger J, Balasubramaniam S. Unsuspected tension pneumothorax as a hidden cause of unsuccessful resuscitation. Tension pneumothorax most commonly occurs in patients receiving positive-pressure ventilation (with mechanical ventilation or particularly during resuscitation). 1993 Dec. 43 (12):709-22. Findings may be affected by the volume status of the patient. Tension pneumothorax is a life-threatening condition caused by the continuous entrance and entrapment of air into the pleural space, thereby compressing the lungs, heart, blood vessels, and other structures in the chest. Following needle decompression, a CXR is done, and a chest tube is usually placed.[30]. Curr Opin Pulm Med. 2009 Mar. 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. Imaging Chest x-ray [6] [8] Indications: all patients suspected of having pneumothorax [QxMD MEDLINE Link]. Numerous techniques exist, and the literature is replete with opinions, but in the first instance relieving the tension, even if not draining the pneumothorax, is life-saving. [QxMD MEDLINE Link].

Shabir Bhimji, MD, PhD Cardiothoracic and Vascular Surgeon, Saudi Arabia and Middle East Hospitals Significant pneumothorax can cause mediastinal shift leading to impaired venous return and hemodynamic compromise. 2006 May. 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. 2006 Jan. 104 (1):5-13.

Michael G Benninghoff, DO, MS Attending Physician in Pulmonary and Critical Care Medicine, Christiana Medical Center 21 (3):393-4. In 90% of the cases, a chest tube is sufficient; however, there are certain cases where surgical interventions are required, and that can either be video-assisted thoracoscopic surgery (VATS) or thoracotomy.

All the above causes can further cause tension pneumothorax as well as: Traumatic and tension pneumothoraces are more common than spontaneous pneumothoraces. In any patient presenting with chest trauma,airway, breathing, and circulation should be assessed. Tension pneumothorax. Recurrences are more common in smokers, COPD, and patients with acquired immunodeficiency syndrome (AIDS).

Ultrasound findings includethe absence of lung sliding and the presence of a lung point. Charles W. Lanks, Vanessa Correa. Ultrasound is about 94% sensitive and 100% specific with a skilled operator. Clinical signs of a tension pneumothorax in the ventilated patient are comparably rapid, with arterial and mixed venous peripheral capillary oxygen saturation immediately decreasing 5.

Sanchez LD, Straszewski S, Saghir A, Khan A, Horn E, Fischer C, et al. Tachycardia is the most common finding, and tachypnea and hypoxia may be present. Depending on the depth of a penetrating chest wound, the air will flow into the pleural space either through the chest wall or from the visceral pleura of the tracheobronchial tree.

Hypoxia. Traumatic and tension pneumothoraces are life-threatening and require immediate treatment.[7]. Knowledge of necessary emergency thoracic decompression procedures is essential for all healthcare professionals. Chest. Other symptoms may include substernal chest pain, usually radiating to the neck, back, or shoulders and exacerbated by deep inspiration, coughing, or supine positioning; dyspnea; neck or jaw pain; dysphagia, dysphonia, and/or abdominal pain (unusual symptoms).
