Is Fentinel a Better Local Analgesic?

The primary determinate of local anaesthetic potency is a, p a, b, molecular weight, c, libit solubility. And i know i'm like drilling this in, but just comes up again and again. I think the dose is taking into consideration the volume and the concentration in it. The testos of an epidoral has two components. You want to make sure that your cateder is not intrthecal nor is it inter vascular. But you can actually separate out the component with either Selitacane or epi. It was tested in 19, 20, 20, 21,. but they do ask about local anaesthetic toxicity. Its almost guaranteed a question
