Flashcards in Trauma #2 Deck (20):
1

Tracheobronchial disruption S/S

-continuous air leak, persistent pneumothorax,
-chest tube continuously bubbles,
-rapidly progressing subcutaneous emphysema,
-pneumomediastinum

2

Tracheobronchial Tx

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

Successful ventilation of 1 lung

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

Esophageal perforation s/s

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

5

Esophageal treatments

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

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.

7

Newtons 1st law

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

8

Newtons 2nd law

Force = mass x acceleration

9

Newtons 3rd law

For every action that is an equal and/or opposite reaction

10

Rear end collisions cause which type of spinal injuries.

T12 - L1

11

2 most common places to have a back injury

#1: lumbar
#2: cervical

12

Hangman's fracture

C2

13

Classic motorcycle head on injury pattern:

Feet caught in foot pegs, femurs strike handle bars, upper body swing forward.

14

Classic motorcycle side impact injury pattern

Legs caught between bike and ground, arm caught beneath body resulting in rib fractures.

15

Which motor vehicle incidents cause most lethal injuries?

Rollover collisions

16

Blood loss percentage that results in uncompensation of BP

>30-40%

17

Blood gathers in which body compartments?

Chest and abdomen
Muscles around long bones,
Retro peritoneum

18

Cold patients and clotting

Decreased clotting ability

19

Travel of high velocity bullets

Greater than 2000 feet per second.

20

Diaphragmatic Rupture S/S, treatments

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
