Q

Tracheobronchial disruption S/S

A
  • continuous air leak, persistent pneumothorax,
  • chest tube continuously bubbles,
  • rapidly progressing subcutaneous emphysema,
  • pneumomediastinum
2
Q

Tracheobronchial Tx

A

Supportive, consider mainstream intubation to ventilate good lung.
-if unsuccessful, tear is distal to cuff in R mainstem, back out and ventilate as normal.

3
Q

Successful ventilation of 1 lung

A

Difficult.
-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.

4
Q

Esophageal perforation s/s

A

Hematemesis, dyspnea (due to secretions in pharynx), dysphasia, fever, infection (blood exposed to gastric contents), shock

5
Q

Esophageal treatments

A

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

6
Q

Other antiemetic treatments

A

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.
7
Q

Newtons 1st law

A

Object in motion will stay in motion, object at rest will stay at rest

8
Q

Newtons 2nd law

A

Force = mass x acceleration

9
Q

15
Q

Which motor vehicle incidents cause most lethal injuries?

A

A

> 30-40%

17
Q

A

Chest and abdomen
Muscles around long bones,
Retro peritoneum

18
Q

Cold patients and clotting

A

Decreased clotting ability

19
Q

Travel of high velocity bullets

A

Greater than 2000 feet per second.

20
Q

Diaphragmatic Rupture S/S, treatments

A

S/S:
-dyspnea, bowel sounds in chest (trauma may decrease belle functions) -cyanosis -scaphoid abdomen (sunken appearance)

Tx: NPO, NGOG (contents need evacuated), intubate/PPV PRN
