Just say you had a 12.5 kg kiddo who spasmed, the recommended dose is 4mg/kg IM
4mg/kg *12.5kg = 50 mg
Then you gotta figure out how much volume of drug to give:
So succ comes 20 mg/cc, so 50/20 = 2.5 cc
So like I said, its not too difficult at all, but it does take a step or two to get from
2)remembering 4 mg/kg
3)administering 2.5 cc of succ
*and before anyone jumps on me about the necessity of 4mg/kg of IM succ and how its not THAT important to get the IM dose of succ exact...relax. It was just an example.
