Flashcards in PRAC: Nerve Block Deck (14):
What should nerve block sites be scrubbed with?
Which anaesthetics can be used for nerve blocking?
What does a palmar/planter digital block? Volume required?
- 70% foot including sole
- most of DIP j
3 approaches to the DIP j specificaly?
- dorsal midline
- approach later/medial to extensor tendon (not really necessary, will stil go though tendon)
- palmar/plantar approach
Approaches to the navicular bursa
> midline navicular position
- horizontal approach
- 30* oblique approach
Appraoches to the PIPj?
- abaxial to extensor tendon
- level of palmar process P1
- V shaped notch
- dorsal:distal palmar P1
- Distal:eminence collateral ligament and proximal P2
- Distal:insertion SDFT
What does the low palmar/plantar nerve block?
- metatarsal nerve
- palmar/plantar nerve
> avoid DFSTS
- dorsal subcutaneous ring block (skin sensation, hindlimbs)
What does an abaxial sesamoid block?
- lat and med palmar/plantar digital NVBs (nerves palamr aspect of bundle VAN)
What does low 4 point block?
- lat and med PALMAR nn. (between suspensory and DDFT)
- lat and med PALMAR METACARPAL nn. (distal to button of splint)
What does low 6 point block?
- lat and med PLANTAR nn.
- lat and med PLANTAR METATARSAL nn.
- DORSAL METATARSAL nn.
Where is the PDNB placed?
- NVB just proximal to the collateral cartilage of the distal phalanx
- PDN most palamr
- aim distally
Where is the ASNB placed?
- palapate NVB at level of base of prox sesamoids
- aim distally
Landmarks of low 4 point?
- palmar nerve: between DDFT and SL
- palmar metacarpal n : below level of button of splint
