SymptomsĬommon symptoms of ear barotrauma include: Ventilator-associated barotrauma is a complex medical concern. In this case, air sacks (alveoli) in the lungs may be ruptured or scarred due to high air pressure within the lungs. A more common form of barotrauma in the lungs is caused by the mechanical ventilation systems used in hospital intensive care units to help patients breathe. This form of barotrauma creates a vacuum in the lungs and can result in bleeding into the lung tissue. The diaphragm is the main muscle used in breathing. It occurs, rarely, in divers who hold their breath, when the diaphragm moves abruptly in a "gasping" effort. It is common in children because their Eustachian tubes are narrower than those of adults and become blocked more easily.īarotrauma in the lungs also can occur, but this is not seen in air travelers. It is much more likely to happen to people who have colds, allergies or infections when they are flying. This complication may require emergency surgery.īarotrauma is the most common medical problem reported by air travelers. If this occurs, the balance center can be affected, resulting in a sensation of spinning or falling called vertigo. In severe cases, it is possible for the pressure to create a leak between the deepest structures of the ear (the fluid-filled bony canals called the cochlea and semicircular canals) and the inner ear space. A ruptured eardrum can result in hearing loss. The eardrum can rupture (break) in severe cases of ear barotrauma, causing bleeding or leaking of fluid from the ear. It can create pain and hearing difficulty similar to a middle ear infection. Fluid behind the eardrum is called serous otitis media. This fluid is drawn out of blood vessels in the lining of the inner ear, and can only drain if the Eustachian tube is open. In more severe cases of barotrauma, the middle ear can fill with clear fluid as the body tries to equalize the pressure on both sides of the eardrum. Your ear will feel stuffed and you may feel as if you need to "pop" it. This can cause pain and can muffle sounds. The pressure change can create a differential between the outer and middle ear that pushes the eardrum inward. Barotrauma of the ear also can happen when scuba divers descend. On an airplane, barotrauma to the ear – also called aero-otitis or barotitis – can happen as the plane descends for landing. Ear barotrauma can occur when these tubes become blocked or partially blocked. These bubbles are constantly moving into the middle ear, where they balance the ear's inner pressure. This is a bubble of air being moved through the Eustachian tube. When you swallow, you may notice a small click in your ears. This connects your ear with the back of your mouth. The only connection between your middle ear and the "outside world" is a thin canal called the Eustachian tube. Your middle ear includes the eardrum and the space behind it. Generalized barotraumas, also called decompression sickness, affects the entire body.

Utilizing lung-protective ventilation strategies may reduce the risk of barotrauma.ĬOVID-19 acute respiratory distress syndrome mechanical ventilation pneumomediastinum pneumothorax pulmonary barotrauma.Medically reviewed by. Pulmonary barotrauma should be considered in patients with COVID-19 pneumonia who exhibit worsening of their respiratory disease as it is likely associated with a high mortality risk. Patients with COVID-19 ARDS have a high incidence of barotrauma. The median length of hospital stay was 22 (15.7 -33.0) days with an overall mortality of 62.5% (n = 20). The incidence of barotrauma was 4.74% (11/232) and 17.35% (21/121) in the non-invasive group and invasive group, respectively. Of the total 353 patients, 32 patients (65.6% males) with a mean age of 63 ± 11 years developed barotrauma in the form of subcutaneous emphysema, pneumothorax, or pneumomediastinum. The remaining 121 patients required invasive mechanical ventilation and were assigned to invasive group. This retrospective cohort study included adult patients diagnosed with COVID-19 pneumonia and requiring oxygen support or positive airway pressure for ARDS who presented to our tertiary-care center from March through November, 2020.Ī total of 353 patients met our inclusion criteria, of which 232 patients who required heated high-flow nasal cannula, continuous or bilevel positive airway pressure were assigned to non-invasive group. In current study, we sought to evaluate the incidence, clinical outcomes, and characteristics of barotrauma among COVID-19 patients receiving invasive and non-invasive positive pressure ventilation. We experienced a high incidence of pulmonary barotrauma among patients with coronavirus disease-2019 (COVID-19) associated acute respiratory distress syndrome (ARDS) at our institution.
