Aspiration of gastric contents into the trachea can cause a variety of injuries to the respiratory system. It is a serious condition that requires immediate medical attention. The most common cause of this condition is vomiting or regurgitation of stomach contents due to various reasons like gastrointestinal disorders, anesthesia, alcohol intoxication, or drug overdose.
When gastric contents enter the trachea, they can cause chemical injury, inflammation, and infection. The acidity of the stomach contents can cause severe irritation and damage to the lining of the trachea, leading to inflammation and swelling. This can cause difficulty in breathing and can lead to further complications like pneumonia, acute respiratory distress syndrome, and even death.
Chemical pneumonitis is the most common injury that occurs when gastric contents enter the lungs, causing inflammation and damage to the lung tissues. The severity of this condition depends on the amount and nature of the aspirated material. The symptoms of chemical pneumonitis include coughing, wheezing, chest pain, fever, and shortness of breath.
In addition to chemical pneumonitis, aspiration of gastric contents can also cause mechanical damage to the tracheobronchial tree. This can lead to airway obstruction, bronchial rupture, and pneumothorax. These conditions can be life-threatening and require immediate intervention.
