When subcutaneous emphysema occurs due to pneumothorax, a chest tube is frequently used to control the latter; this eliminates the source of the air entering the subcutaneous space. [2] If the volume of subcutaneous air is increasing, it may be that the chest tube is not removing air rapidly enough, so it may be replaced with a larger one. [8]
In traumatic pneumothorax, chest tubes are usually inserted. If mechanical ventilation is required, the risk of tension pneumothorax is greatly increased and the insertion of a chest tube is mandatory. [13] [42] Any open chest wound should be covered with an airtight seal, as it carries a high risk of leading to tension pneumothorax.
Chest tubes are also provided in right angle, trocar, flared, and tapered configurations for different drainage needs. As well, some chest tubes are coated with heparin to help prevent thrombus formation, though the effect of this is disputed. [16] Chest tube have an end hole (proximal, toward the patient) and a series of side holes.
Diagnosis may be suspected based on low blood pressure, jugular venous distension, or quiet heart sounds (together known as Beck's triad). [2] [1] [7] A pericardial rub may be present in cases due to inflammation. [2] The diagnosis may be further supported by specific electrocardiogram (ECG) changes, chest X-ray, or an ultrasound of the heart. [2]
A chest radiograph of a flail chest associated with right sided pulmonary contusion and subcutaneous emphysema. Diagnosis is by physical examination performed by a physician. The diagnosis may be assisted or confirmed by use of medical imaging with either plain X ray or CT scan. Paradoxial movements of flail segments.
Air is trapped in the chest cavity outside the lungs (pneumothorax) in about 70% of TBI. [4] [10] Especially strong evidence that TBI has occurred is failure of a pneumothorax to resolve even when a chest tube is placed to rid the chest cavity of the air; it shows that air is continually leaking into the chest cavity from the site of the tear. [11]
Thoracentesis / ˌ θ ɔː r ə s ɪ n ˈ t iː s ɪ s /, also known as thoracocentesis (from Greek θώραξ (thōrax, GEN thōrakos) 'chest, thorax' and κέντησις (kentēsis) 'pricking, puncture'), pleural tap, needle thoracostomy, or needle decompression (often used term), is an invasive medical procedure to remove fluid or air from the pleural space for diagnostic or therapeutic ...
Sketch depicting a chest drainage in course. Chest drains are surgical drains placed within the pleural space to facilitate removal of unwanted substances (air, blood, fluid, etc.) in order to preserve respiratory functions and hemodynamic stability.
