We are currently having the same discussion in our office. An email was just sent out stating that in order to give a patient one gram of rocephin, I need to use a one gram vial and reconstitute with 3.6 cc of 1% lidocaine as well as a 250mg vial and reconstitute with 0.9cc of 1% lidocaine. They state that we should give all of the medications (all four cc's) in order to give one gram of rocephin. This sounds like it would be 1250mg of rocephin? Does anyone know what the correct answer is if I want to give a patient one gram of rocephin?
