Classify colloid intravenous fluids and outline the pharmacology of the hydroxyethyl starches.
This question, of high and common clinical relevance, was poorly answered. Candidates were
expected to mention colloid intravenous fluid were either semi-synthetic or plasma derivatives. A
clear outline of the pharmacology, that is formulation (eg molecular weight, amylopectin/glucose
polymer), pharmacokinetics and adverse effects, etc was expected of a good answer.
