- 00:01Welcome to Yale emergency ultrasound
- 00:04nerve block series. Today, we're
- 00:05going to be talking about
- 00:06fascia ileaca and pain blocks.
- 00:11Because both of these blocks
- 00:12are large falling blocks, we
- 00:14recommend about thirty to forty
- 00:16cc total of anesthetic and
- 00:19normal saline together.
- 00:21As far as your choice
- 00:23of anesthetics, we recommend ropivacute
- 00:25or bupivacute
- 00:26for longer lasting effects
- 00:28and consulting your pharmacist regarding
- 00:31the dose
- 00:32as well as the concentration.
- 00:34Now, let's talk about the
- 00:36indications for these two blocks.
- 00:38Fascia iliaca block provides anesthesia
- 00:41to the regions above.
- 00:43So it's used for low
- 00:45force mechanism hip fracture
- 00:47as well as mid shaft
- 00:48femur fracture.
- 00:50As far as the pain
- 00:51block, it will help with
- 00:53intratracheateric
- 00:55fracture,
- 00:56astrotabular
- 00:57fracture,
- 00:58pubic merrimae fracture,
- 00:59as well as hip dislocations.
- 01:03Now let's look at the
- 01:04anatomy.
- 01:05This is the right lower
- 01:06extremity.
- 01:08If you look, you can
- 01:10see navel
- 01:11from femoral nerve,
- 01:13artery,
- 01:14vein, and lymphatics.
- 01:16On top of the screen,
- 01:17you can see fascia latae.
- 01:20If you follow along down,
- 01:22you can see fascia iliaca.
- 01:24And right below the fascia
- 01:26iliaca
- 01:27is where you will dump
- 01:28all the anesthetics.
- 01:31So now let's review the
- 01:33anatomy on a real live
- 01:34model.
- 01:36You'll want to use the
- 01:37linear probe in nerve block
- 01:40settings
- 01:41Position your probe as if
- 01:43you were doing a femoral
- 01:44central line
- 01:46Slide the probe a little
- 01:47laterally
- 01:48that way you can identify
- 01:50the femoral artery
- 01:52Follow along even more lateral,
- 01:55and here, you can see
- 01:56your fascia lata.
- 02:00Right underneath,
- 02:02you can see the fascia
- 02:03iliaca.
- 02:05Going through the fascial layers,
- 02:07you should feel
- 02:08two pops from fascia lata
- 02:11and fascia iliaca.
- 02:14And of course, last but
- 02:15not least, here's your iliopsoas
- 02:17muscle.
- 02:18So now that you're ready
- 02:20to block your patient, let's
- 02:21talk about the steps.
- 02:23Step one,
- 02:24prep for the block.
- 02:26First, of course, you will
- 02:27need to get consent from
- 02:28your patient.
- 02:30Put the patient on the
- 02:31monitor.
- 02:32Finding your resources, which includes
- 02:34grabbing the nerve block kit
- 02:36outside of a sixteen, extra
- 02:38hands that can help you
- 02:39push the anesthetics,
- 02:40and, of course, discussing with
- 02:42your pharmacists.
- 02:44Step two, identify
- 02:46the landmark and anatomy on
- 02:48your patient. Don't forget to
- 02:49use about one to two
- 02:51cc of lidocaine to make
- 02:52a wheel, then stabilize your
- 02:55non dominant hand that's holding
- 02:56the ultrasound probe.
- 02:58And when you're ready, you're
- 02:59going to poke the patient.
- 03:01Then you'll poke and pop
- 03:03through fascia latae and fascia
- 03:05ileaca. Once you've popped through
- 03:07your fascia ileaca,
- 03:08make sure to have your
- 03:09assistant give you about one
- 03:11to two cc to hydro
- 03:13dissect. You'll switch to anesthetics
- 03:16once you're ready
- 03:17and inject
- 03:18four to five cc
- 03:20every thirty seconds or so.
- 03:23Make sure to check-in with
- 03:25your patients for signs and
- 03:26symptoms of the test.
- 03:29Wow. You've made it this
- 03:30far. Now let's talk about
- 03:31the PING block.
- 03:33Pericapsular
- 03:34nerve root, also known as
- 03:35PING,
- 03:36provides anesthesia to the hip
- 03:38joint without affecting the motor
- 03:40function of quadriceps
- 03:41muscle or altering the sensory
- 03:43exam.
- 03:44Now let's talk about some
- 03:46of the anatomy and your
- 03:47probe of choice.
- 03:49You're going to be using
- 03:50curvilinear probe
- 03:52as this will be a
- 03:53deeper block,
- 03:54and you're going to be
- 03:55coming in at a very
- 03:57steep angle that you may
- 03:58not be familiar with.
- 04:00Using your curvilinear probe,
- 04:02find your femoral vein and
- 04:03femoral artery.
- 04:05From there, you're going to
- 04:06move up and laterally,
- 04:09finding your iliacus muscle and
- 04:11your psoas tendon.
- 04:13Your goal is to aim
- 04:15tighter dissect behind the psoas
- 04:17tendon
- 04:18with tactile sensation of hitting
- 04:20the ilium.
- 04:22Once you're there, make sure
- 04:24you ask your assistant to
- 04:25give about one to two
- 04:26cc of normal saline to
- 04:29hydrodissect.
- 04:30And when you see the
- 04:31iliacus muscle lift up
- 04:33from the bone, that's how
- 04:35you know you have separated
- 04:37the plane.
- 04:38At this time, you may
- 04:39now switch over to your
- 04:40anesthetics
- 04:42And now let's look at
- 04:43it on a real model
- 04:45Here we can see your
- 04:46femoral vein and femoral artery
- 04:48in the center
- 04:49At the bottom of the
- 04:50screen
- 04:51What you're seeing is the
- 04:52femoral head
- 04:54Once you see this, you
- 04:55can move
- 04:56cranially and laterally.
- 04:59As we move the probe
- 05:01lateral and cranially,
- 05:02you can identify some of
- 05:04the muscles and other structures.
- 05:06On screen left, you can
- 05:08see the iliacus muscle.
- 05:10You will also see psoas
- 05:12tendon coming into view, which
- 05:14looks like a circle above
- 05:15the bone.
- 05:16Your psoas tendon sits on
- 05:18top of iliopsoas
- 05:20notch,
- 05:20which sits in between your
- 05:23AIIS
- 05:23and iliopsoas
- 05:25eminence.
- 05:27Now you're ready to block
- 05:28the patient.
- 05:29Step one, prep the patient.
- 05:33Make sure you flush and
- 05:34prep your needle. That way,
- 05:36you don't inject air into
- 05:38the muscle and obstructive views.
- 05:41Step two,
- 05:42identify the anatomy,
- 05:44make a wheel, and stabilize
- 05:46your nondominant
- 05:47hand.
- 05:48Step three,
- 05:49poke
- 05:50and hydro dissect.
- 05:52Ask your assistant
- 05:54to inject one to two
- 05:55cc of normal saline.
- 05:57And then when you're ready,
- 05:59make sure to switch to
- 06:00your anesthetics and give incremental
- 06:03injection.
- 06:04Don't forget to check-in with
- 06:05your patients for signs and
- 06:06symptoms of LAST.
- 06:12For more information on LAST,
- 06:14please review the material
- 06:16sent at the beginning of
- 06:17the nerve block series.
- 06:19We also recommend downloading safe
- 06:21local
- 06:22and MD Calc for safe
- 06:23and appropriate dosage for your
- 06:25patient.
