Summary chart: Interscalene, supraclavicular, infraclavicular, axiallary, bier

List the brachial plexus part

volume

indications

and notes

A
2
Q

TAP block:

indications

A
  • Somatic sensation of anterior abdominal wall
  • Subcostal TAP- upper abdomen
    • dermatomes T6-T9
  • Lateral TAP- lower abdomen
    • dermatomes T10-T12
  • Open abdominal surgeries
  • C-section, total abdominal hysterectomy
  • renal transplants
  • nephrectomy
  • illiostomy
  • exploratory laparotomy
3
Q

Lumbar Plexus

What major nerves are involved?

Affects motor and sensory to what?

A
  • Nerves:
    • ventral rami of L1-L4
      • within psoas muscle
    • Femoral L2-L4
    • lateral femoral cutaneous L1-L3
    • Obturator L2-L4
  • Motor to:
    • hip
    • anterior thigh
    • knee
  • sensory to:
    • medial upper and lower leg/ankls
4
Q

Femoral Nerve Block

motor innervation

sensory innervation

indications

A
  • Motor: quads and sartorious
  • sensory:
    • anterior thigh
    • anterior/medial knee
    • medial lower leg/ankle (saphenous nerve)
  • Indications:
    • surgery to anterior thigh
    • quadriceps muscle biopsy
    • knee arthroscopy/ACL
    • complete blockade of lower expremity when combined with sciatic nerve block
5
Q

Femoral Nerve block:

disadvantages

contraindications

A
  • Disadvantage:
    • loss of quadriceps (motor) strength and control
    • limits early postoperative ambulation and physical therapy
    • falling out of favor and being replaced by adductor canal block
  • Contraindications:
    • pre-existing femoral neuropathy
    • local infection/enlarged groin lymph nodes
6
Q

What is the femoral 3-in-1 block?

A
  • by injecting enough local, you can anesthetize the lateral femoral cutaneous, femoral, and obturator nerves with a single injection below the inguinal ligament
  • out-dated and mostly abandoned
  • little evidence to being successful
7
Q

Adductor canal block

nerve

indications

advantages

A
  • Saphenous nerve- sensory branch of femoral
    • anterior and medial knee
    • medial lower leg and ankle
  • indications-
    • knee analgesia (TKA, ACL, Foot/ankle)
  • advantages:
    • spares motor of quadricepts
    • allows for early ambulation and physical therapy
8
Q

Sacral plexus

nerves

A
  • L4-5 and S1-4
  • posterior thigh
    • posterior femoral cutaneous nerve S1-S3
  • Posterior knee, lower leg and foot
    • sciatic nerve L4-S4
  • Does NOT include anterior thigh
9
Q

Sciatic nerve

roots

Where does it travel?

motor

sensory

A
  • Nerve roots L4-5 and S1-3
  • Exits the pelvis at the greater sciatic forament. travels under gludeus maximus
  • separates mid-thigh into tibial and common peroneal nerves
  • motor:
    • posterior thigh, leg, and fot
  • sensory
    • skin of posterior thigh/knee, lateral leg and foot
10
Q

Sciatic nerve block

indications

advantages

disadvantages

A
  • indications:
    • anesthesia/analgesia to posterior distal thigh, posterior knee, lower leg/ankle/foot
  • advantages
    • complete blockade of leg in combination with femoral nerve block
  • disadvantages
    • deep nerve sructure, difficult to identify
    • motor blockade can limit ambulation/physical therapy
11
Q

Popliteal nerve block

which nerves?

indications

advantages

A
  • Tibial and common peroneal nerves
  • indications
    • ankle and foot surgery
  • advantages
    • spares posterior thigh muscle
    • facilitates early physical therapy/ambulation
12
Q

Ankle block

nerves (5)

indications

A
  • nerves
    • posterior tibial
    • deep peroneal
    • superficial peroneal
    • sural
    • saphenous
  • indications
    • procedures that involve the foot/toes
