ABSTRACT

Background:

Lumbar plexus block (LPB) is one of the anesthetic options in the elderly patients undergoing hip surgeries.

Video referent to Popliteal Sciatic Nerve Block

The items to be considered on the following video are:

  • Block characteristic: Intermediate technique
  • Patient position: Supine, hip and knee flexed, pillow under the ankle
  • Ultrasound equipment: Linear probe, 38 mm
  • Specific ultrasound setting: High frequency
  • Important anatomical structures: Biceps and semi-membranosus muscles, popliteal vessels
  • Ultrasound appearance of the neuronal structures: Main sciatic nerve: hyperechoic,

Video referent to subgluteal nerve block

The items to be considered on the following video are:

  • Block characteristic: Intermediate technique
  • Patient position: Supine, 90º flexed hip and knee or lateral, 45º flexed hip or prone position
  • Ultrasound equipment: Linear probe, 38 mm
  • Specific ultrasound setting: High – medium frequency
  • Important anatomical structures: Adductor magnus muscle,

Video referent to obturator nerve block

The items to be considered on the following video are:

  • Block Characteristic: Intermediate technique
  • Patient Position: Supine, outside rotated leg
  • Ultrasound equipment: Linear Probe
  • Specific Ultrasound Setting: High Frequency
  • Important anatomical Structure: Pectineus, long and short adductor muscles
  • Ultrasound appearance of the neuronal structures: Hyperechoic,

Video referent to femoral nerve block

The items to be considered on the following video are:

  • Block characteristic: Basic technique
  • Patient position: Supine, slightly outside rotated lower extremity
  • Ultrasound equipment: Linear probe 38 mm
  • Specific ultrasound setting: Maximum frequency
  • Important anatomical structures: Femoral artery, iliopectineal arch, psoas major muscle
  • Ultrasound appearance of the neuronal structures: Poor echogenicity,

Ultrasonography Guided Lower Extremity Blocks

Infographics that help us understand the use of USB and USC needles

  • The USB (30º Bevel needles for peripheral nerves blocks under ultrasound guidance) for the research of muscular nerve sheaths was conceived so you can observe them clearly – whilst moving through the tissues – on the screen of an ultra sound machine thanks to a surface treatment of the steel tubing.
