Flashcards in Trauma #2 Deck (20):
Tracheobronchial disruption S/S
-continuous air leak, persistent pneumothorax,
-chest tube continuously bubbles,
-rapidly progressing subcutaneous emphysema,
Supportive, consider mainstream intubation to ventilate good lung.
-if unsuccessful, tear is distal to cuff in R mainstem, back out and ventilate as normal.
Successful ventilation of 1 lung
-tilt pt so ventilated lung is slightly down.
Ventilated lung all the way down: too much blood to lung
Ventilated lung all the way up: too little blood to lung.
Esophageal perforation s/s
Hematemesis, dyspnea (due to secretions in pharynx), dysphasia, fever, infection (blood exposed to gastric contents), shock
Supportive, ngt/ogt (blood in stomach = emesis... Safer to place tube past disruption than to allow gastric contents into chest cavity), antiemetics (May require more than 1), antibiotics
Other antiemetic treatments
Need to block as many as 6 receptors
-Zofran, Benadryl, Phenergan, proton inhibitors
-Zofran is a poor rescue drug (already vomiting)
-Phenergan is much better rescue drug.
Newtons 1st law
Object in motion will stay in motion, object at rest will stay at rest
Newtons 2nd law
Force = mass x acceleration
Newtons 3rd law
For every action that is an equal and/or opposite reaction

2 most common places to have a back injury
Classic motorcycle head on injury pattern:
Feet caught in foot pegs, femurs strike handle bars, upper body swing forward.
Classic motorcycle side impact injury pattern
Legs caught between bike and ground, arm caught beneath body resulting in rib fractures.
