Epidemiology of pneumothorax in England. Duringinspiration, a sizeable high-pressure air collection accumulates in the intrapleural space and is not able to completely exit during expiration. Occasionally, the tension pneumothorax may be tolerated and its diagnosis delayed for hours to days after the initial insult. The timely and accurate evaluation leadsto early interventions decreasing mortality and morbidity. Tension pneumothorax is an uncommon condition with a malignant course that might result in death if left untreated. 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.

Findings on lung auscultation also vary depending on the extent of the pneumothorax. Am J Respir Crit Care Med. 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. 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. 2008 Oct. 74 (10):958-61. In these cases, emergency medical technicians (EMTs), ED nurses, and providers have a role in recognizing this entity promptly and initiating early interventions.

While this is a commonly considered cause of shock in obvious trauma, it can also occur non-traumatically in ventilated patients, or in the setting of occult trauma. Respir Med. Close radiographic view of a patient with spontaneous primary pneumothorax due to a left upper lobe bleb (same patient as in the previous image). This creates a diffusion gradient for nitrogen, thus accelerating the resolution of the pneumothorax. This is a chest radiograph of an elderly male with chronic obstructive pulmonary disease who presented with a second left-sided spontaneous pneumothorax in 2 months. [Full Text]. Murray and Nadel's Textbook of Respiratory Medicine. Distended neck veins and tracheal deviation are also often present. Hypoxemia also triggers pulmonary vasoconstriction and increases pulmonary vascular resistance. The chest pain is described as severe and/or stabbing, radiates to the ipsilateral shoulder and increases with inspiration (pleuritic). Tension pneumothorax most commonly occurs in patients receiving positive-pressure ventilation (with mechanical ventilation or particularly during resuscitation). [QxMD MEDLINE Link]. Greenberg MI. 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 Leslie MD, Napier M, Glaser MG.

No study has shown that the number or size of blebs and bullae found in the lung can be used to predict recurrence. Thorax. [QxMD MEDLINE Link]. 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. Check for errors and try again. This rise in pressure further compresses the lung and decreases its volume.

[QxMD MEDLINE Link]. Jalota Sahota R, Sayad E. Tension Pneumothorax. Nevertheless, tension pneumothorax should always be a consideration when acute compromise occurs. 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. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. [39]In another study, patients with procedure-related tension pneumothorax had better outcomescompared to pneumothoraces occurring in the ITU due to barotrauma.[40]. 2004 Mar. Anesthesiology. As the pressure increases, it will cause the mediastinum to shift towards the contralateral side, contributing further to hypoxemia.

That pressure gradient between the lung and pleural space prevents the lung from collapsing. [31][32][33][34], Patients requiring surgical intervention are usually patients with bilateral pneumothoraces, recurrent ipsilateral pneumothoraces, first presentation in patients with high-risk professions like pilots and drivers, and patients with persistent air leaks (for more than seven days). In either case, as the collection grows further, it exerts a positive mass effect on the mediastinum (compression of vessels and heart) and the opposite lung.

Another sign, the Hamman signa precordial crunching noise synchronous with the heartbeat and often accentuated during expirationhas a variable rate of occurrence, with one series reporting 10%. [QxMD MEDLINE Link]. 329 (7473):1008. 2002 Mar. 2006 May. 2004 Oct 30. In severe cases, the increased pressure can alsocompress the heart, the contralateral lung, and the vasculature leading to hemodynamic instability and cardiac arrest in some cases. Chest. Only 1.25% of the air is absorbed without oxygen in 24 hours. 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. During video-assisted thoracic surgery (VATS), pneumothorax is treated with pleurodesis. Presentation is variable and may initially have no symptoms. Findings may be affected by the volume status of the patient.

When examining a patient for suspected tension pneumothorax, any clue may be helpful, as subtle thoracic size and thoracic mobility differences may be elicited by performing careful visual inspection along the line of the thorax. Risk factors and treatment. Lippincott Williams & Wilkins. Dulchavsky SA, Schwarz KL, Kirkpatrick AW, Billica RD, Williams DR, Diebel LN, et al. 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. Patients with trauma tend to have an associated pneumothorax or tension pneumothorax 20% of the time. Well-tolerated primary pneumothorax can take 12 weeks to resolve. Blunt thoracic trauma patiens may have tracheal deviation and deformities of the chest wall may be observed. [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.
