Trauma

Question 1

T/f: prognosis for trauma is overall very good and most patients survive to discharge

Answer 1

true

Question 2

In trauma, tissue oxygen consumption (increases/decreases), whereas delivery of oxygen (increases/decreases) and this leads to decreases tissue perfusion and shock.

Answer 2

tissue oxygen consumption (increases), whereas delivery of oxygen (decreases)

Question 3

what are the 3 types of shock involved in trauma?

Answer 3

1. hypovolemic (most common)
2. hypoxic
3. distributive

Question 4

In cases of hemorrhagic shock, which 2 variables are DECREASED and thus leading to tissue hypoperfusion?

Answer 4

1. decreased cardiac output
2. decreases mean arterial pressure

Question 5

In cases of hemorrhagic shock, why do we need to increase perfusion as promptly as possible?

Answer 5

because tissue hypoperfusion leads to the activation of the neuroendocrine stress response and causes downstream negatives effects

Question 6

What occurs as a result of cellular and tissue hypoperfusion / oxygen deprivation?

Answer 6

1. anaerobic metabolism starts
2. increased blood lactate
3. overproduction of oxygen radicals and toxic metabolites
4. cellular injury
