thoracic trauma Flashcards
what does ATOM CT stand for in trauma ?
airway obstruction
tracheobronchial injury
open pneumothorax
massive haemothorax
cardiac tamponade
tension pneumothorax
immediately life threatening thoracic injuries
what is found on auscultation in tension pneumothorax vs pneumothorax ?
tension pneumothorax - absent breath sounds
pneumothorax - diminished breath sounds
what are the adjuncts of breathing ?
pulse oximeter
CXR
eFAST
ABG
if you are presented with a case of laryngotracheal injury what is the best management ?
tracheostomy rather than cricothyroidotomy
when do we suspect tracheobronchial injury ?
1- persistent air leak after chest tube placement even after correct placement has been confirmed
2- rate of air accumulation is higher than rate of drainage
3- large pneumo mediastinum
4- oxygenation is worse after placement of the chest tube has been placed
what is the management for open pneumothorax ?
3 sided cover over defect
chest tube
definitive operation
when is haemothorax classified as massive ?
when blood loss is over a litre and a half
what is the management of massive haemothorax ?
tube thoracotomy
volume restoration
operative intervention
what is the classic presentation of cardiac tamponade ?
accumulation of fluid in the pericardial sac
1- becks triad :
hypotension
muffled heart sounds
distended neck veins
2- kussmaul’s signs : paradoxical rise in JVP during inspiration
3- pulsus paradoxus : A decrease in systolic blood pressure by more than 10 mmHg during inspiration
what is the first line management for cardiac tamponade ?
pericardiocentesis
how is a diagnosis of tension pneumothorax made ?
clinical diagnosis , no chest x ray
what are the signs of tension pneumothorax ?
air trapped in the pleural cavity
tracheal deviation away from the affected side
reduced vocal resonance
hyperresonance on the affected side
haemodynamically unstable
what is thee management for tension pneumothorax ?
immediate needle decompression , in the 5th intercostal space midclavicular line
then insert a chest tube to avoid recurrence
what is found on chest x ray of hemothorax ?
opacity rising towards the axilla
what is the mechanism of injury when it comes to traumatic aortic disruption ?
rapid acceleration / deceleration
