Equine Nerve Blocks Uiuc Dr. A Stewart

Front 1

Palmar or plantar digital nerve block

Back 1

nerves: medial and lateral PD nerves
location: distal pastern just proximal to the collateral cartilages
region blocked: most of the foot, but not the dorsal (front) portion

Front 2

Palmar or plantar digital nerve block with dorsal ring block

Back 2

nerves: med and lat PD nerves, dorsal branches of digital nerves
location: distal pastern just proximal to the collateral cartilages
region blocked: entire foot

Front 3

Abaxial sesamoid block

Back 3

nerves: medial and lateral palmar/plantar nerves
location: abaxial surface of proximal sesamoids
region: entire digit +/- partial fetlock

Front 4

low palmar/plantar nerve block

Back 4

nerves: med and lat palmar/plantar nerves, med and lat palmar/plantar metacarp/tarsal nerves
location: level of distal aspect of splints
region: fetlock

Front 5

low palmar/plantar nerve ring block

Back 5

nerves: med and lat palmar/plantar nerves; med and lat palmar/plantar metacarp/tarsal nerves; hindlimb--dorsal metatarsal nerve; forelimb--diffuse subcutaneous nerves
location: distal aspect of the splints
region: fetlock

Front 6

high palmar block

Back 6

nerves: med and lat palmar nerves, med and lat palmar metacarpal nerves
location: proximal aspect of metacarpus (inject deep and superficial)
region: entire metacarpus

Front 7

wheat block (high 2-point block)

Back 7

nerves: lateral palmar nerve, medial palmar nerve
location: lateral--just distal to the accessory carpal bone; medial--proximal aspect of metacarpus
region: entire metacarpus

Front 8

high plantar block

Back 8

nerves: med and lat plantar nerves, med and lat plantar metatarsal nerves
location: proximal aspect of metatarsus
region: entire metatarsus

Front 9

median, ulnar and musculocutaneous nerve blocks

Back 9

median: distal to elbow joint
ulnar: proximal to the accessory carpal bone
musculocutaneous: mid-to-prox antebrachium along the cephalic and accessory cephalic veins
region: mid-to-distal antebrachium and carpus

Front 10

peroneal and tibial block

Back 10

nerves: tibial nerve, superficial and deep fibular
location: proximal to the calcaneous
region: distal crus and tarsus

Front 11

which drugs are the best to use for diagnostic analgesia?

Back 11

mepivicaine is best due to duration and it can be use inside the joint
bupivicaine is ok
do NOT use lidocaine in the joint

Front 12

T/F sedation is indicated for working up a lameness case

Back 12

false: sedatives (xylazine, detomidine) may provide analgesia, so lameness is masked

Front 13

describe the re-evaluation period after giving diagnostic analgesia

Back 13

check 5 minutes after injection
follow up in 10-15 minutes if only partial response initially
positive result = 70-80% improvement

Front 14

T/F the abaxial sesamoid blocks the palmar/plantar digital nerve

Back 14

false NOT palmar/plantar digital nerve (just the palmar/plantar nerve)

Front 15

with which blocks is it easy to accidentally inject the joint space?

Back 15

low palmar/plantar nerve block
high palmar block

Front 16

What is the wheat block an alternative for and why would you use it?

Back 16

alternative to high palmar block
used to prevent accidental injection into the cricometacarpal joint space
