GCS
41
What are normal levels of cortisol in a normal person throughout the day? what about during stress?
25 mg normally, but can increase in excess of 100 mg during stress
42
How do steroids affect a patient during a stress situation?
they blunt normal feedback mechanisms between hypothalamus, pituitary and the hormone. this prevents the body from making endogenous cortisol. during stress, when they require more cortisol, the body is unable to synthesize any and can cause wide swings in BP and HR among other things
43
Who requires stress steroid dosing?
any patient who has been on steroids for at least a month in the past 6-12 months will need supplementation
44
What kind of patients are usually on steroids?
autoimmune disease patients, cancer patients, etc.
45
what kind of difficulties can the CRNA expect if the patient is taking an MAOI?
life threatening interaction between MAOIs and MEPERIDINE or EPHEDRINE as a result of excessive release of catecholamines, causing HTN crisis
46
What are some specific MAOIs that CRNAs should be aware of?
iproniazid, phenelzine, isocarboxazid, moclobemide, befloxatone, brofaromine, selegiline
47
What kind of patients might be taking methotrexate?
RA, ankylosing spondylitis, cancer, MS patients
48
What are the adverse effects of methotrexate?
immunosuppression, anemia, thrombocytopenia, pulmonary toxicity, renal toxicity, hepatic toxicity
49
What sort of labs/diagnostic studies should the CRNA have on a patient taking methotrexate?
CBC (b/c the drug affects rapidly proliferating cells)
BMP (b/c of renal toxicity)
PFTs and LFTs if the history warrants
50
What sort of targeted assessment might the CRNA perform on an MS patient?
an immunosuppression assessment because of the drugs that MS patients take
51
How might the CRNA assess a patient with MS's immunosuppression?
any recent history of infection or illness? (persistent cough/sore throat)

time course of the disease? (early phase or recovery phase)
precipitating factors?
onset of symptoms?
55
Knowing the symptoms of GBS, how should the CRNA prepare?
facial paralysis - is the brainstem involved more?
difficulty swallowing -pharyngeal weakness may lead to airway collapse
impaired ventilation - may need to maintain current vent settings
decreased deep tendon reflexes - regional anesthesia and positioning!
extremity paresthesias - careful with positioning
pain - treat ahead of time and manage carefully afterwards
ANS dysfunction - check an ECG and ask about orthostatics, prepare for vasoactive med use
56

Age of symptom onset?
recent exacerbations and hospitalizations?
current and past symptoms? how long did they last? what helped?
temperature regulation issues?
dizziness or fainting (orthostatics)?
dysphagia/difficulty breathing?
pulmonary infection?
Hx of peroglide therapy?
when do you take your meds?
```
57
Why should the CRNA ask about peroglide therapy to a Parkinson's patient?
it is a discontinued drug r/t mitral and aortic valve problems, so the CRNA may consider ordering an echo to check for valve dysfunction
58
What medication considerations must the CRNA keep in mind for a Parkinson's patient?
should continue to take all medications
should be aware of the side effects of all meds
if patient is taking MAOIs, prepare rescue drugs appropriately
if patient is taking anticholinergics, consider dosing NMB more often
maintain levodopa schedule as allowed
59
What must the CRNA keep in mind when positioning a parkinson's patient?
they may have contractures and spasticity, so allow for natural range of motion and pad well
60
Before the physician uses electrocautery....
turn off the DBS in parkinson's patients
61
What are some important anesthetic considerations for a patient with LBP or disc herniation?
maintain a natural ROM for positioning and laryngoscopy
assess baseline motor strength and sensory function pre-op
what drugs are they currently on? what helps? what doesn't help?
are you taking high dose opioids or NSAIDS? (may need to bridge)
consider ordering a CBC/T&S, considering large blood loss is possible
62
What is the distinction between acute or chronic spinal cord injury that the CRNA must be aware of?
acute patients are at risk for spinal shock (hypotension, loss of reflexes)
chronic patients are at risk for autonomic dysreflexia (HTN crisis, bradycardia)
63
What pre-op testing might be required for an acute spinal cord injury patient receives an anesthetic?
CBC/type and cross/chem 7 - to assess fluid status
ECG/CXR - to assess for catecholamine induced arrhythmias
vasopressor therapy - for severe hypotension r/t sympathectomy
ventilatory therapy required depending on level of injury
are there associated injuries the CRNA needs to be aware of?
64
What kind of questions should the CRNA ask a patient with chronic spinal cord injury?
any episodes of autonomic dysreflexia? what relieved it?
do you have old ICU or OR records?
what is the level of injury -- may help determine ventilatory reserve and dictate use of opioids
do you have any skin breakdown - carefully position
contractures or spasticity - need to be aware for positioning
65
What sort of documentation is required before a TIA/CVA patient is given an anesthetic?
what is the history? when did it occur?
residual symptoms?
were the causes of the stroke corrected?
continuation/discontinuation of anticoagulants?
66
What sort of physical assessments and studies might be helpful when assessing a patient with TIA or CVA?
assess for symptomatic carotid bruit -- needs to be assessed 1st and may require a carotid ultrasound
what sort of TIA symptoms have they experience -- have they been taken care of?
echo to evaluate valve function and emboli
67
What questions/assessments are required for a patient with high ICP, head injury or intracranial tumor?
mechanism of injury/illness
location, size, time course of illness/injury
CT or MRI reports/imaging
current LOC
ICP status (associated symptoms? HA, N/V, bradycardia, HTN)
CV status (r/t catecholamine storming?)
cranial nerve dysfunction (may indicate brainstem dysfunction)
muscle strength and sensation
68
What pre-op/diagnostic studies might be helpful for a neuro injury patient?
endocrine function tests to r/o pituitary involvement
fluid status - r/t use of diuretics
CBC/Chem 7 - blood loss possible
T&S - blood loss possible
ECG - r/t catecholamine storming
echo - to evaluate valve or emboli
CXR/ABG - to evaluate strength of current vent settings
knowledge of baseline vital signs to maintain CPP and CO2 levels
continue current meds like anticonvulsants and steroids
69
What is an important consideration if a head injury patient is taking an anticonvulsant?
the drugs will induce CYP450 enzymes and may make it difficult to maintain deep plane of anesthesia, may need more frequent dosing of NMB, patient should continue to get these drugs on time, anesthesia may blunt the symptoms of a seizure
70
What questions should the CRNA ask if the patient has a seizure disorder?
what meds are you on?
type of seizure? length? precipitating factors? recovery period?
hx of status epilepticus? what helped? associated complications?
71
What tests or other considerations must the CRNA be aware of when caring for a patient with a seizure disorder?
labs such as CBC, platelets, electrolyte panel are common
may need anticonvulsant level if its a new therapy, otherwise ok
cancel case unless seizures are under control as per neurology
72
What is the main concern when caring for a patient with SLE?
complications associated with the widespread vasculitis may appear or be exacerbated
73
What specific questions should you assess for in a patient with SLE?
```
do you exercise? how much? tolerance?
do you have a skin rash? where?
any difficulty breathing? use of accessory muscles?
history of cardiac problems?
anemia?
hx of reflux or N/V episodes?
problems with your kidneys?
normal range of motion and any joint/limb pain?
```
74
What diagnostic should be considered in a patient with SLE?
chem panel to assess fluid status
CBC and platelets to assess for anemias
PFTs to eval restrictive disease if pulmonary involvement is suspected
echo and cardiac consult if hx of cardiac involvement
pre-op pulse ox, especially if value is difficult to obtain on finger
albumin level and renal function tests to eval renal involvement
75
Why might a pulse ox reading be difficult to obtain in a patient with SLE?
because vasospastic disease like Raynauds Syndrome is possible and may require pulse ox reading from the ear
76
What are common meds that SLE patients can be on that would affect their coagulation status?
NSAIDS (ibuprofen, indomethacin)
ASA
Cox-2 inhibitors
DVT preventative therapy like lovenox or heparin
77
What joints are commonly affected by RA?
knees, elbows, antlanto-axial, shoulder, hands, feet, hips, ankle
78
What areas should the CRNA pay especially close attention to when assessing an RA patient? why?
TMJ - may make laryngoscopy difficult if limited ROM
atlanto-axial - may make intubation difficult/consider advanced imaging
cricoarytenoid arthritis - make require smaller ETT if hoarse voice, dyspnea, stridor, tenderness
79
What kinds of diagnostic studies should be ordered in an RA patient? Why?
PFTs/ABG if restrictive lung disease is suspected -often have pulmonary fibrosis and accessory muscle weakness and dyspnea may be the 1st sign of cardiac trouble
echo/ekg - if cardiac involvemment is suspected
blood studies - NSAIDs, ASA, methotrexate all prolong bleeding time and may cause anemia... were they bridged with alternative pain therapies?
80
What are some special considerations when giving anesthesia to a patient with osteoathritis?
note the natural range of motion, focusing on key areas of patient complaint
ask about medications, what works, what doesn't, do they do steroid injections, when was the last dose?
81
What are some special considerations when taking the health history for a myasthenia gravis patient?
note the degree of skeletal muscle weakness so that you can adjust for your neuromuscular blockade appropriately
meds -- cholinesterase inhibitors antagonize NMB, steroid use might require a stress dose, immunosuppressive therapy r/t infection risk
82
What are the special concerns with muscular dystrophy?
you should note progression of the disease, their natural range of motion, and current muscle strength (esp pulmonary)
consider an RSI if they have delayed gastric motility
consider PFTs in the case of severe pulmonary function
echo/ekg if you suspect wasting of the cardiac muscle
83
What are the special concerns with myasthenic syndrome?
note the degree of skeletal muscle weakness
ask about timing/progression of the disease
medications
84
What are the special concerns when providing anesthetics to a patient with marfan syndrome?
perform a thorough cardiopulmonary exam -- usually an echo to eval valve function, also a high risk for pneumothorax
careful assessment of TMJ
85
Sample questions for seizure/convulsion/paralysis?
```
precipitating factors?
how long does it last?
how was it treated?
what medications are you on?
