In this video, I'd like to show you
the concept of a linear anesthesia.
00:09
Typically done when you have an
incision you're going to create.
00:13
The way this works
is you simply start
from the proximal side
of the incision,
and you provide a line of a bleb,
so to speak.
00:22
So you would inject
through the tissue.
00:24
And then as you advance
the needle across,
above the skin, I'll show you
what's happening beneath the skin.
00:30
You basically advancing your needle
underneath your wound
as you're giving a bleb,
and you go as far as you can.
00:36
And then you stop,
take your needle out.
00:39
If you need to reload
with more lidocaine
or whatever you're choosing to use.
00:42
And then you'll pick up
where you left off
and keep on going inside the tissue
until you get to the point
where you've met your distal end.
00:50
That way, you have a nice bleb
that goes all the way down
where your incision is
you've covered the patient
adequately with linear anesthesia.
00:58
That said,
this is option number one for
let's say, if you have wounds
that you're going to create.
01:04
If the patient presents to you with
an incision that's already made,
let's say from a laceration
from some blunt force trauma,
which you can choose
to do if you've
already gone
through the process of
cleaning out your wound
and providing good anesthesia.
01:17
If necessary prior for
something more original
for a large laceration
with like an anesthesiologist.
01:24
Or if you have something
smaller going on here,
you may choose to
perform this procedure
going through the incision outward.
01:31
So if you have a laceration that
you feel is appropriate to close,
you can actually give anesthesia
through this outwards.
01:38
So sometimes what you'll see
people do is they'll go in.
01:40
So it's kind of like
fanning out like the sun.
01:44
And they'll go through
the sidewall, the dermis.
01:47
And the first thing
I'd recommend you do
if you have a laceration that's
open is to drip lidocaine in there,
because the skin barrier
is already broken,
and the pain is already there.
01:56
So you have the benefit
of going directly
to the deeper dermis
with anesthetic.
01:59
Let it kind of sit there
for a minute or two,
and then go ahead
and start fanning out
through the sidewalls of the tissue.
02:05
If a wound is clean enough to close,
it's cleaned out to get anesthesia
through the insides of the incision.
02:11
As opposed to having to make
multiple pokes on the outside
and penetrate the tissue more.
02:16
You're better to work through
the one incision you already have.
02:18
So go ahead and practice this.
02:20
Just to kind of visually understand
how to do this
with your needle and syringe.
02:25
Again, it won't actually
react in the tissue as well.
02:27
It's not going to bleob up for you.
But you understand the concept
that want to least do
the proper hand movement.
02:31
So go ahead and practice that
on your own.
