Air Will Find a Way: A Case Report and Literature Review on Tracheostomy-Induced Ectopic Air.

Tracheostomy can lead to various complications, one of which is ectopic air in different compartments of the body. Here, we present a rare case of tracheostomy-induced ectopic air: a combination of subcutaneous emphysema, pneumomediastinum, and pneumoperitoneum. This case also presents a literature review on some of the common mechanisms responsible for pneumomediastinum following tracheostomy and the mechanism of pneumoperitoneum following pneumomediastinum. Tracheal injury, tube-related complications, and alveolar rupture are common mechanisms that can lead to pneumomediastinum and subcutaneous emphysema after tracheostomy. Air can then dissect into the abdomen leading to pneumoperitoneum. Knowledge of the anatomic or embryologic development of the thoracoabdominal continuum can help understand the spread of air from one compartment to another. Investigation as simple as a chest X-ray, along with clinical features, can help identify these complications and be used to monitor the course.
