Question regarding Humalog insulin - page 2
Hi All, I have a quick insulin scenario that I need help understanding. I am a student nurse currently working my gero rotation. I had a patient who is Type 1 diabetic with severe depression.... Read More
0Jun 11, '10 by Blondie24Quote from cocoon2butterflyI definitely understand the rationale about giving it after IF the patient doesn't end up eating/eating very little; however, being that her BS was extremely high, I just figured that if the insulin was given before and she didn't end up eating that the Humalog wouldn't lower her so much that she'd become hypoglycemic....just lower it some.She wanted it given after d/t the poor appetite/depression.
I work at a pediatric psych hospital, and we give the insulin after...if you give it before per guidelines, the patient might not eat anything, simply because they're not hungry, or because they are trying to manipulate the situation - and trust me, you don't want 20 units of insulin on board and they haven't eaten...not at all pretty...
And Humalog, regardless of eating or not, is actually pretty dang quick, so yeah, it's a smidge slower if you give it after you eat, but not so much so it drastically affects the blood sugar...
Hope that helps!
On a side note, does anyone know how much the BS is lowered per every 1 unit of insulin?
0Jun 11, '10 by RNMeg, BSNQuote from Blondie24This depends on the patient's sensitivity and the rate of absorption at the injection site. My husband is a type I diabetic, and his pump is set to give him different amounts of insulin at different times of the day because sensitivity changes throughout the day. Also, if he places his pump site in tissue that is heavily scarred, absorption will be slower and he'll have higher FSBS's until he moves the pump site.On a side note, does anyone know how much the BS is lowered per every 1 unit of insulin?
0Jun 11, '10 by cocoon2butterflyThink about it this way - generally speaking, when using a sliding scale, whatever amount of insulin you give is going to account for the blood sugar and the meal. So if you only have one of those factors (i.e. high blood sugar, but pt didn't eat), the blood sugar will probably go low...
And as for the amount the blood sugar drops per unit of insulin, it varies. WIDELY. For example, for me (I'm a type 1 diabetic), it drops 40 points - for a friend of mine who's insulin resistant, it drops hers 15 points, and for the 2 y/o diabetic that I babysit, it drops his 150 points (he has a pump, no way you could give doses that small via syringe).
So, it varies for everybody, there is no magic number...as I believe someone mentioned, it's one of those things where we like to say "your mileage will vary"...
0Jun 11, '10 by anonymous1919I'm curious.... I don't remember the details of this conversation because it was 2 years ago but this is what I remember. I saw a friend of mine- a nurse (we worked together) take a residents BS. It was 260's about and I was like "WOAH" and she said that was just a little higher than normal for him. She gave him a dose of insulin but not enough to bring his insulin down to what is considered "normal". I was confused by this because isn't the goal to get him down to "normal"? She said that since 260 is only a little above normal for him, and if they were to give him enough to make him what is really considered "normal" he would be at risk for hypogylcemia, and potentially go into a diabetic coma because his body was adjusted to the fact that he's run in the 200's for years and years. So maybe (although 555 is extreme) it's the same thing...... anyone totally disagree?
