Block of posterior nerve roots interrupts ______ and _____ sensation.

A

visceral

17
Q

Blockade of anterior nerve roots prevent ____ and ____ outflow.

A

Motor

autonomic

18
Q

Somatic blockade interrupts painful stimuli and abolishes skeletal muscle tone.

Results in _____ blockade.

A

differential blockade

19
Q

Differential blockade: mainly _____ at site of injection.

2 dermatomes away ____ blockade

2 dermatomes away from that, _____ blockade

A
  • motor
  • sensory
  • sympathetic (test with ice)
20
Q

Autonomic blockade:

Sympathetic response originating from ____ region.

Spans T __ to ___

A

thoracolumbar

T1 - L2

21
Q

Parasympathetic is from _____ region.

Will NOT block vagus since vagus from brainstem

A

craniosacral

22
Q

Cardiovascular blockade results in

A

decrease BP, HR, contractility, vasomotor tone

inhibit cardiac accelerators at T1-T4

23
Q

Epidural results in urinary retention. True or false?

A

True

24
Q

Advantages of epidurals:

A
  • Decreased risk of post dural puncture headache (later)
  • Decreased risk of hypotension because of slower onset
  • greater control over intensity of sensory block
  • greater control over motor block
25
Q

Disadvantages of epidural

A
  • slower onset time
  • block is less dense
26
Q

Epidural test dose:

  • Volume:
  • Concentration:

Why test dose?

A
  • 3 ml of 1.5% lidocaine with 1:200,000 epi (5mcg/ml)

To ensure we are in the right space

27
Q

Epidural increase in HR indicates what during a test dose?

A

The epidural is in the vein/artery.

28
Q

If the patient complains cannot feel legs right after giving test dose, indicates what?

A

the epidural is in the spinal region

29
Q

Local agent used in epidural has to be ______ ______.

A

PRESERVATIVE FREE

30
Q

Spinal anesthesia pharmacology

A
  • preservative free
  • add vasoconstrictors and/or opioids
  • baricity
31
Q

CSF specific gravity is _____ to _____.

A

1.003-1.008

32
Q

To make hypobaric solution add ____ which is ____ than CSF.

To make hyperbaric solution add _____ which is ____ than CSF.

A

sterile water, lighter

glucose, heavier

33
Q

Complications of neuraxial anesthesia:

A
  • High neural block
  • CARDIAC ARREST
  • Urinary retention
  • Inadvertent total spinal anesthesia
  • POSTDURAL PUNCTURE HEADACHE when dura is breached due to decrease pressure of CSF.
  • neuro injury
34
Q

Postdural puncture headache

Treatment?

A
  • onset 12 hours to several days after
  • lie down, in the dark
  • drink lots of Mt. Dew (caffeine stimulates CSF production)
  • Conservative–NSAIDS, Tylenol, fluid, caffeine
  • EPIDURAL BLOOD PATCH
35
Q

Caudal anesthesia

A

Sacral hiatus creased by unfused s4-5

common in kids for procedures below diaphragm

36
Q

Place epidural at ___-____.

A

L3 - L4
