bleeding

36
What 3 things can help with anesthesia induction?

37
It is not uncommon to do what kind of induction in children?
inhalation
38
What are the 2 sedatives that we use for induction?

39
What is a positive of etomidate?
it can cause some adrenal suppression for 24 hours.
40
What is etomidate good for?
good for AAA (large vessel grafts) because there is not big blood pressure on new graft.
41
What is negative side effect of etomidate?
you need prophylactic antiemetic because it can cause emesis
42
What is the downside of brevital?
the therapeutic dose and toxic dose are next door neighbors, so small margin of error
43
What does brevital lower?
the seizure threshold
44
What will we still use brevital for?
ECT
45
Nurse needs to do what with patient during induction?
remain with the patient
46
The nurse needs to limit what kind of stimulation during induction?
sensory stimulation
47
The stress response of induction is what?
increase in BP and Heart rate
48
As the nurse, know where what are located during induction?
the emergency/difficult intubation cart and trach tray are located
49
MI's occur during what phase of induction?
the excitatory phase
50
Nurses want to do slow what for induction? why?
slow deliberate positioning because of loss of compensatory vasoconstriction
51
Patients lose what during anesthesia?
compensatory vasoconstriction, which can cause venous pooling
52
What are 2 things to remember for asthmatics on induction?
1. need to be deeper for intubation 2. bronchodilator use prior to intubation
53
MH usually occurs when?
during induction, after given the triggering agents
54
MH has variable what? which means?
variable penetrance which means that it is dependent on dose and duration
55
do you still need to vigilant of MH throughout the procedure?
yes because of variable penetrance
56
During intubation patients are at risk for what?
aspiration
57
What 4 patients are most at risk for aspiration?
1. GERD 2. trauma 3. awake intubation 4. pregnancy/obesity
58
For patients who are at risk for aspiration what can you use to help with intubation?
cricoid pressure
59
Why do you do cricoid pressure?
to prevent vomiting and aspiration, so we don't let go until the cuff is up
60
What is cricoid also known as?
SELLECK maneuver
61
What do you have to have as a nurse in order to do moderate sedation?
competency
62
What is important for pain post op?
pain goals so we can understand when we need to give meds
63
We control our own pain with what?
natural endorphins
64
We have what for our endorphins? so we can do what?
we have receptors for our endorphins so we can build muscle, move stuff and run from tigers
65
Sometimes the natural ability to ignore pain is a what
a big advantage?
66
What can cause a histamine release in some people?
synthetic opioids
