Patient has had 20mls of lidocaine 0.5%. Max is 3mg/kg and he weighs 80kg. How much more can you give?
28ml
0.5% = 0.5g in 100 ml
Therefore the 20mls of that solution that he’s already been given, must contain 0.1g of lidocaine (or 100mg)
Max is 3mg/kg which means for him max is 240mg. So 240mg-100mg = 140mg left.
Then 20/100x140= 28mL
