Insulin Question

individual dependent. - there is not a set dose that is lethal

The recommended dosage is 0.5-1.0U/kg/day. Toxicity from a hypoglycemic reaction would depend on a number of factors including kidney and liver function, how much the person had to eat, or continued to eat after the injection, rate of absorption relative to percentage of SC fat etc. Also depends on what type of insulin....I'm assuming we're talking about Regular, where a rapid, immediate blood sugar fall could be a problem. IV administration recommends pushing no more that 50U over a 1 minute period....if that gives you an idea of where the danger zone might lie.

:chuckle If you are planning to kill someone with an insulin overdose make sure they are truly diabetic! I remember hearing about that prison nurse who killed her husband with an insulin overdose. The only problem was that he was not a diabetic and so she got busted and went to prison. :chuckle

How much did the person in the incident receive and were they in DKA or diabetic at all?

:rotfl: WAY too funny....I wonder if she used to list "strong critical thinking skills" on her nursing resume......

Like Morphine, it is pretty dependant on the individual. I have had a nursing instructor that tooh around 200u Q4, and still crank high blood sugars. And then I have had 4u crash someone out.

For a type 1 diabetic, they are much more insulin sensitive than a type 2, and less insulin will cause more violent hypoglycemia more rapidly. This is also because the type 1's counterregulatory process (ie release of glucagon) is impaired compared to a type 2 or a regular patient.
