Oh dear I see some of the same cranks as in sci.med but hopefully
there are actually some nurses here.
I'm one of those pedantic/binary sort of people who investigates
everything to the bitter end and I'm having trouble seeing exactly
where to insert the needle (1.5" 25ga 0.6ml) into the butt. I
understand that the butt in medical terminology is not the same as in
popular parlance and I understand that there's the sciatic nerve
running diagonally through the lower inside part and I understand it's
not a good idea to hit it. OTOH I don't see large numbers of cases of
medical personnel hitting it so either it's hard to do or the damage
is much exaggerated.
I've read about splitting the butt cheek (in my terminology we are
blessed with two butt cheeks, a left and a right, the two of which
constitute one "butt" and they're separated by a butt crack) into four
quadrants and only using the upper outside quadrant. But, are the
individual quadrants square or rectangular? Where is the upper line of
the imaginary quadrants located? I presume the inner line follows the
butt crack and the outer line would be where a flat object such as a
book held vertically and jammed up against the thigh/hip would be. The
bottom of the quadrants, I guess, is level with the point where the
butt joins the leg. BTW, I'm planning on measuring this with a ruler
and marking up the butt with something like a magic marker.
As to the top line I've read the statements about the iliac crest and
consulted the anatomy sites. If I understand correctly the iliac crest
is the top of the pelvic bone but where on the top? On the outside the
pelvis comes to a point which the common man would call the hip as in
"He put his hands on his hips". But then the line of the pelvis drops
or curves down as it heads towards the spine. Supposedly the top line
is two to three inches below the iliac crest but where on the iliac
crest? Or maybe the two or three inches refers to the point of
injection after establishment of the imaginary quadrants?
Further, looking at the illustrations the top outside quadrant seems
to include an area of pure bone at least on me. I'm male and 160lbs
and I reckon I have a nice curvaceous protruding butt (no you can't
have pictures) but I can feel pelvic bone as I get closer to what I
think is the top line of the quadrants. BTW, I don't see too much on
google about hitting bone (nothing in fact). What happens if I do hit
the bone? Agonizing pain? Broken needle?
Any help would be appreciated. |

The sciatic nerve is deep and tough. Gluteal injections are not given
anywhere near that area anyway.

If you do it correctly you won't hit the bone. After the intial
"jab"(even the initial jab shouldn't break it), you shouldn't be
pushing hard enough to break the needle at all.

The darkened areas on the picture are where the needle goes.

I am a nursing student graduating this week. In our first semseter
when we were taught about IM injections, we were told by our
professors, and all of our texts stated that IMs are not to be injected
into the gluteus muscle anymore. There were too many s/e. Hope that
helps. Make sure whatever you are reading is current.

OK guys, happy to see such a rush of knowledgeable people willing to
share their experiences.... Well, just in case there are some laymen
watching...
I did my first IM injection, or rather my wife did her first under my
direction. All my fears were groundless. The needle slid in almost
without sensation just to the right (right butt) of the band-aid
covering the PCP's effort of Tuesday. She didn't even know that she'd
pushed all the fluid in. Shows me the syringe and asks "Is this
empty?" "Were you planning on inserting it again if I said no?" "Yes"
from her but fortunately it was empty.
Oh, and Chuck, what's an s/e? All the texts on the internet say the
gluteal muscle is a fine site. So does my PCP. Are you sure you're not
talking about the obese or children? |

In my first semester we were taught and read that the dorsogluteal is
not used anymore because tthere were too many problems with hitting the
sciatic nerve. I realize where all of the placements are, and where
the nerve is, but that is what we were taught and read.
Hope that helps...

s/e would probably mean "side effect". When giving myself an IM
injection I always use the top of the thigh......good solid muscle and
very minimal pain there. |

O dear, s.o. without a clinical background teaching theoretical safety and
on their way to the next fashion statement for the sake of s/e and their
insurance policy. (If you think I sound sceptical, I am). Of course anyone
can miss an artery. However some of us never miss. Bet you I could hit a
sciatic nerve if I'd want to.

More fat and less muscle apparently reduces the efficacy of gluteal
intramuscular injections, according to research reported at the 91st annual
meeting of the Radiological Society of North America.
In a study of 50 healthy volunteers, injections into the buttocks reached
muscle in just "8% of women and 32% of men in our study," said Dr. Victoria
Chan, registrar in clinical medicine at the Adelaide and Meath Hospital,
Dublin, Ireland.
Dr. Chan's team weighed and measured the 50 patients, who were all scheduled
for an abdominal and pelvic CT scan and were receiving IM medications.
Before the scan, the IM injection was given with the addition of 1 mL of
air, into the upper outer quadrant of the buttocks using a standard 3 cm
needle. The location of the air bubble was then measured on the scan.
In most cases, the needle did not penetrate through the fat layer, even in
half of the six patients who were considered underweight (BMI less than 20).
Dr. Chan said the majority of those who received a subcutaneous injection
were female, and had an average fat thickness greater than 2 cm and a muscle
thickness less than 3 cm.
The subjects who got an IM injection were all male, with average fat
thickness less than 2 cm and muscle thickness greater than 3 cm.
"Our study has demonstrated that a majority of people - especially women -
are not getting the proper dosage from injections to the buttocks," said Dr.
Chan.
"This is a cautionary tale," said Dr. Michael Brant-Zawadski, medical
director of radiology at Hoag Memorial Hospital Presbyterian, Newport Beach,
California. "Perhaps the upper arm may be a better site than the buttocks in
heavier people or in women, or perhaps longer needles are the way to get
medicine where it needs to be."

I think it's a real safety issue. It's long been 'wrong' to inject
children's gluteal, precisely because defining 'upper outer' is not an exact
science - and the sciatic nerve can appear in that quadrant.
I think it has been established that injections toward the lower inner of
the upper outer quadrant present a real risk in may adults too.
Much safer to give IM injections in the upper, outer mid thigh area - risks
of major artery or major nerve are very small indeed.
