Mechanical trauma of the pharynx

Introduction to pharyngeal mechanical trauma The mechanical trauma of the pharynx is caused by direct violence from the outside, such as war wounds, traffic accidents, work injuries, suicides, etc. It can also be caused by internal trauma such as surgical injury or foreign body injury, and external stab wounds or cuts are more common in the mouth. In the pharynx and throat, the wound is mostly between the hyoid bone and the thyroid cartilage. The cut of the neck and the neck is mostly rampant. The stab wounds, cuts and cuts caused by sharp weapons are mostly blind tube wounds. The entrance is small, piercing deeper into the inside, or penetrating the wound. A contusion is a blunt injury that can cause deep tissue breaks, which often cause extensive damage to the neck tissue. Pharyngeal contusion is mainly local pain, speech, swallowing, coughing, pain, sharp wounds, wound hemorrhage, subcutaneous emphysema, hemoptysis, such as injury and large blood vessels can be shocked or died due to blood loss, blood can flow into the larynx Cause cough, difficulty breathing, contusion or blast injury or accompanied by laryngeal trauma can cause throat edema, hematoma, laryngeal cartilage fracture and difficulty breathing, penetrating wound can cause wound drooling and difficulty swallowing, wound secondary infection has fever, etc. Systemic symptoms. basic knowledge Sickness ratio: 0.001%-0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: edema, fracture, difficulty swallowing

Pharyngeal mechanical trauma

It is caused by direct violence from outside, such as war wounds, traffic accidents, work injuries, suicides, etc. It can also be caused by internal trauma such as surgical damage and foreign body damage.

Pharyngeal mechanical wound prevention

Attention should be paid to the use of antibiotics to prevent infection, to prevent scarring stenosis, and to treat complications.

Pharyngeal mechanical trauma complications Complications, edema, difficulty in swallowing

Contusion or blast injury or accompanied by laryngeal injury can cause edema of the throat, hematoma, laryngeal cartilage fracture and difficulty in breathing, penetrating wound can cause wound drooling and dysphagia, secondary infection of the wound has systemic symptoms such as fever.

Pharyngeal mechanical trauma symptoms Common symptoms Dysphagia Difficulty breathing Fever trauma Secondary infections Freckle bleeding Hemorrhagic blood shock

Pharyngeal contusion is mainly local pain, speech, swallowing, coughing, pain, sharp wounds, wound hemorrhage, subcutaneous emphysema, hemoptysis, such as injury and large blood vessels can be shocked or died due to blood loss, blood can flow into the larynx Cause cough, difficulty breathing, contusion or blast injury or accompanied by laryngeal trauma can cause throat edema, hematoma, laryngeal cartilage fracture and difficulty breathing, penetrating wound can cause wound drooling and difficulty swallowing, wound secondary infection has fever, etc. Systemic symptoms.

Examination of pharyngeal mechanical trauma

First of all, pay attention to the general condition of the patient, such as breathing, pulse, blood pressure, etc., internal stab wound, often injured and oropharyngeal wall or soft palate, pharyngeal hemorrhage and hematoma, mucosal rupture, uvula, submucosal blood stasis, It is blue-violet and swollen. The neck is often swollen or has ecchymosis. If there is bleeding and emphysema in the soft tissue of the neck, the neck is thick. If there is a laryngeal contusion, there may be a laryngeal cartilage fracture and dislocation. Although small, but the damage is deep, mostly complicated by subcutaneous emphysema and hemoptysis, cut more common in the neck of the neck, more common in the transverse incision, mostly located in the thyroid tongue periosteum and thyroid cartilage, often due to platysma and neck Longitudinal muscle contraction to expand the wound, severe open throat trauma patients, often through the wound to see the pharyngeal wall and laryngeal tissue, gunshot wounds, wounds and other traumatic range, often accompanied by large blood vessels, cervical vertebrae, Cervical trachea or esophageal trauma, the wound is located in the large vessel part of the neck, the examination should be cautious, prepare good lighting equipment and rescue hemostasis equipment, otherwise you can not rush to take out the clots or foreign bodies in the wound, and should not use probes Wound, so as not to cause bleeding.

Diagnostic diagnosis of pharyngeal mechanical trauma

Diagnosis can be based on medical history and clinical manifestations without identification.
