Visceral Structures (pain): what type of fibers involved
C-afferent fibers
A-delta fibers
(visCerAl)
Visceral Structures (pain): when do the C-afferent and A-delta fibers get activated? (what causes this type of pain)
-disease
-inflammation
-isometric contraction
-ischemia
-rapid distention
(remember these are organs- thus when you get appendicitis you hurt from the inflammation stretching, ischemia etc)
Visceral Structures (pain): C-afferent and A-delta fibers are activated by what?
noxious stimuli
alogenic substances
Visceral Structures (pain): the C-afferent fibers and A-delta fibers act as what???/
transducers
Visceral Structures (pain): the C-fibers and A-delta fibers are conducted to the \_\_\_\_ \_\_\_\_\_\_ or \_\_\_\_\_\_\_\_
dorsal horn
or
medulla
Visceral Structures (pain): The C-fibers and A-delta fibers are conducted to the dorsal horn and medulla, and are influenced by what?
intensity
duration
microenviroment
What are 2 ways to decrease pain?
- augmentation
- inhibition
what is inhibition
- counterirritation
- -rubbing, vibration, more sophisticated methods
what is augmentation?
- sensation by repeated noxious stimuli
- lowering the threshold by alogenic substances
What opens the Gate after nerve injury?
decreased inhibition
increased excitation
what the reduction in inhibitory postsynaptic currents the consequence of (r/t peripheral nerve injury related pain)
decreased GABA responsiveness
what causes the decreased GABA release and consequent reduced inhibition? (r/t teh gate theory)
apoptosis

- infection at injection site
- uncorrected hypovolemia
Epidural complications
- Hypotension
- total spinal
- Local toxicity
- Headache
- Local site pain
- Zebras (also the red panda)
Continuous epidural analgesia dose, meds, rate etc. (this is just Mcd’s way)
10mL 0.25% bupivicaine (2.5mg/ml=25mg)
100 mcgs fentanyl
8 ml PF NS
After this loading dose maintain rate at 3-5 ml/hr
ITA advantages
excellent analgesia
no sympathetic block
ambulatory pt
ITA (with or without anesthetic) meds and doses
25 mcgs fentanyl
100-150 mcgs (0.2-0.3 ml) astromorph
What is the combined tech??? “the best of both worlds”
Perform ITA
place epidural catheter for later use if needed
