College Answer

The first part of this question was answered well by most candidates.
Generally, the second part of the question was poorly organised by many candidates, the 
consequence being that many opportunities for picking up marks were lost. A brief statement 
as to what lignocaine is, its presentations and dose, some facts about PD and PK followed by a 
few lines on toxicity (CC/CNS ratio) was mostly what was required. Only a few candidates 
mentioned lignocaine toxicity.
