115
Q

pain receptors. how do c fibers differ from a-delta fibers

A

c-fibers can exhibit temoporal summation

116
Q

pain receptors. why are c fibers suspects of chronic pain

A

because they can exhibit temporal summation

117
Q

pain receptors. c fibers. what is temporal summation

A

repetiton of a stimuli to the c fiber does not allow the c-fiber to return to base line…and each subsequent stimulation causes an increase response to a given stimuli

Q

Methadone. How long does it last.

A

It can accumulate in the system up to 1 week after discontinuation

124
Q

Methadone. Why is it good for use in chronic pain.

A

Because it activates the delta receptor. This receptor has a role in tolerance. Thus it can help from decreasing effects of tolerance.

125
Q

Methadone. What cardiac risk does it have.

127
Q

pancreatic cyst. what is an adverse effect of celiac block

A

lysis an sympathetics…increase parasymp tone…diarrhea

128
Q

celiac plexus block. why do u have to block a sympathetic chain for visceral pain

A

diabetic periphereal neuropathy

130
Q

duloxetine. moa

A

snri

131
Q

duloxetine. how would an snri help with diabetic neuropathy

A

the increase in serotonin and norepi help enhance inhibitory neurons that inhibit transmission from nociceptive ascending nerve fibers

132
Q

duloxetine. besides snri. does it do nmda blockade

A

no

133
Q

suboxone. what is it

A

buprenorphine/naloxone

134
Q

suboxone. compared to morphine. which has more mu affinity

A

it has higher mu affinity, but once bound has less activation compared to morphine…thus morphine is the better analgesic

135
Q

suboxone. what does it do to the kappa recepetor

A

antagonist

136
Q

suboxone. if taken before surgery. will the naloxone affect the intraop opiods?

A

no…suboxone is given sublingual…so its systemic absorption is so low, that it does not effect intraop opiods

137
Q

suboxone. so why is naloxone given if it does not prevent abuse of other IV narcotics

A

it is placed in the sublingual pill to prevent abuse of the suboxone itself

138
Q

suboxone. so if the naloxone does not have effect on intraop opiods…are pt on chronic suboxone have any effect with pain meds intraop and post op

A

these pts may be more resistant and have higher tolerance to pain meds bc the buprenorphine may antagonize other IV mu drugs
