BACKGROUND Cricoid pressure is considered to be the gold standard means of preventing aspiration of gastric content during Rapid Sequence Intubation (RSI). Its effectiveness has only been demonstrated in cadaveric studies and case reports. No randomised controlled trials comparing the incidence of gastric aspiration following emergent RSI, with or without cricoid pressure, have been performed. ...

Aspiration of bile is an underpublicized aspiration syndrome. Using a porcine lung model, the physiologic response and the histopathology of lung tissue were evaluated after the intratracheal instillation of sublethal doses of bile. Twenty-one domestic swine (11 to 19 kg) were the studied population. Three groups of five swine were evaluated: a control group received intratracheal physiologic s...

Inhalation of acid fumes and aspiration liquid substances or gastric contents may not initiate dyspnea within several hours after exposure but result in delayed onset alveolar edema. The present report presents three cases inhalation chemical that resulted acute respiratory distress syndrome (ARDS). Due to different underlying reasons, patients developed ARDS resulting from pneumonitis pulmonar...

Introduction:   Radiotherapy with or without surgery plays an important role in the treatment of patients with esophageal cancer. In the treatment planning of esophageal cancer, usually normal lung volume was observed in the treatment fields and probably received high radiation dose. The incidence of radiation pneumonitis (RP) after radiotherapy (RT) for sensitive organ of lu...

Meconium aspiration syndrome (MAS) is a common cause of severe respiratory distress in term infants, with an associated highly variable morbidity and mortality. MAS results from aspiration of meconium during intrauterine gasping or during the first few breaths. The pathophysiology of MAS is multifactorial and includes acute airway obstruction, surfactant dysfunction or inactivation, chemical pn...

A 38-year-old, previously healthy fire eater presented with severe pneumonitis after incidental aspiration of an unquantifiable amount of petroleum. The chest CT revealed extensive pulmonary consolidations, and the laboratory results showed massively elevated inflammatory markers. An intravenous antibiotic treatment was started and, after improvement of symptoms and inflammatory markers, contin...
