Traumatic and tension pneumothoraces are life-threatening and require immediate treatment.[7]. Identify the pathophysiology of tension pneumothorax. 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. Pneumothorax is the collapse of the lung when air accumulates between the parietal and visceral pleura inside the chest. 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. Tension pneumothorax is primarily a clinical diagnosis and prolonged diagnostic studies should be avoided in favor of initiating immediate treatment. Knowledge of necessary emergency thoracic decompression procedures is essential for all healthcare professionals. The incidence of traumatic pneumothorax depends on the size and mechanism of the injury. Clinical presentation. Prospective evaluation of thoracic ultrasound in the detection of pneumothorax.

Close radiographic view of a patient with spontaneous primary pneumothorax due to a left upper lobe bleb (same patient as in the previous image). Presentation is variable and may initially have no symptoms. 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. Early recognition of this condition is life-saving both outside the hospital and in modern ITUs. [3], On examination, it is essential to assess for signs of respiratory distress, including increased respiratory rate, dyspnea, and retractions. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. [Full Text]. [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. In cases of severe chest trauma, there is an associated pneumothorax 50% of the time.

Pneumomediastinum must be differentiated from spontaneous pneumothorax. 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. 2004 Feb. 11 (2):211-3.

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. Pneumothorax is when air collects in between the parietal and viscera pleurae resulting in lung collapse. Miller JS, Itani KM, Oza MD, Wall MJ. In this situation, the ipsilateral lung will, if normal, collapse completely (although a less than normally compliant lung may remain partially inflated). [QxMD MEDLINE Link].

Tension pneumothorax is a clinical diagnosis requiring emergent needle decompression, and therapy should never be delayed for x-ray confirmation. There are two types of pleurodesis: mechanical and chemical. 2009 Oct. 52 (5):E173-9. The pain is sharp, worsens with inspiration or coughing, and . [QxMD MEDLINE Link]. [37][38], Ventilator-related tension pneumothorax has been found to have dire outcomes and result in death more frequently. Hypotension that worsens with inspiration Hypotension that worsens with inspiration is associated with tension pneumothorax due to compression of the heart and great vessels (obstructive shock). In PSP, chest often improves over the first 24 hours, even without resolution of the underlying air accumulation. 2003 Jul-Aug. 70 (4):431-8. 2005 Aug. 128 (2):720-8. POCUS has sensitivity and specificity ranging from 90-100% for detecting pneumothorax. [QxMD MEDLINE Link]. The development of tension pneumothorax in patients who are ventilated will generally be of faster onset with immediate, progressive arterial and mixed venous oxyhemoglobin saturation decline and immediate decline in cardiac output. Symptoms typically include sudden onset of sharp, one-sided chest pain and shortness of breath. 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. 2004 Jun. Eventually, impaired venous return results in cardiac arrest and death. This website also contains material copyrighted by 3rd parties. Life-Threatening Simultaneous Bilateral Spontaneous Tension Pneumothorax - A case report -. [8][28][29], If the patient is hemodynamically unstable and clinical suspicion is high for pneumothorax, immediate needle decompression must be performed without delay. Young and otherwise healthy patients can tolerate the main physiologic consequences of a decrease in vital capacity and partial pressure of oxygen fairly well, with minimal changes in vital signs and symptoms, but those with underlying lung disease may have respiratory distress.

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. [QxMD MEDLINE Link].
