oesageal and tarcheal injuries Flashcards
symptoms that could lead to oepsageal injury
dyshpagia
odonophagia
hematemesis, hemoptysis, hoarseness,
physical exam findings of oespageal injuries
subcutanoeus emphysema , neck hematoma, and neck tenderness.
what do you call air in the mediatsitum
pneumomediatsinum
hammans sign
and where do we see it
crunching, rasping sound, synchronous with the heartbeat, heard over the precordium in spontaneous mediastinal emphysema. the sound is similar to crackles that you would hear
- boerheaves
what can cause a pneumomediastinum
injury to the esophagus
injury to the trachea
iatrogenic - endoscopic, Intubuation
Boerhaave syndrome
uncommon but life-threatening condition causes by a full thickness rupture of the oesophagus.

presentaiton o fboerheaves
Severe tearing chest pain worse on swallowing
Little/no haematemsis
Signs of shock
Subcutaneous emphysema
Pneumomediastinum, pleural effusions, pneumothorax on x-ray
in boerheaves what should be avoided
OGD- you can worsen the perforation
managemtn of boerheaves
IV fluid resuscitation
IV antibiotics to cover/treat mediastinitis
Surgical correction
mortality is high
x ray signs of a pneumoediatinum
double eheart border?
widening of the mediastinum
pneumothorax- air is getting everywhere
def of pneumomediatsiumm
Pneumomediastinum is the presence of extraluminal gas within the mediastinum. Gas may originate from the lungs, trachea, central bronchi, oesophagus, and peritoneal cavity and track from the mediastinum to the neck or abdomen.
( so its vice versa) hence why in laprsocopic surgery a complication is a pneumomediastinum because you indeuce a pneumoperitoneum and this can track to the mediatsimym.
overt pneumomediastimum
occult pneumomediastinum
if pneumomediastinum is visible on chest x-ray it is termed overt pneumomediastinum whereas if it is only visible on CT then it is termed occult pneumomediastinum 8.
what can cause oespagea perforation
boerhaeves
endoscoppic
oesophageal carcinoma
how can we injurt he tracheobronecheal tree
bronchosocpy
trachestomy
ET intubatioon
does pnemomediatnum always need a cause
Although it is rare, pneumomediastinum can occur spontaneously. This is considered benign and generally affects young adult males 9,10.
tx of pneumomediastimum
Most pneumomediastinum requires no treatment, with the air being gradually absorbed on the following days.
Tension pneumomediastinum can be fatal and usually requires intervention with insertion of drains through the anterior thoracic wall aiming decompression

why is tracheal injury so dangerous and mortality
The trachea is near the esophagus, vagus nerve, recurrent laryngeal nerves, thyroid, carotid arteries, jugular veins, innominate arteries and veins, the pulmonary trunk, the azygos vein, and the aorta with the vertebra and spinal cord posteriorly.[
Tracheal trauma may follow from either cervical or thoracic injury; cervical injuries tend to be more visible and obvious; thoracic injury may go unnoticed.
how does inhaltion cause damge to trachea
inhalation and aspiration cause damage to the mucosal lining of the trachea, leading to inflammation, ulceration, and softening of the cartilaginous portions
