Describe the mechanisms by which heat is lost from the body (40% of marks). Discuss the importance of each of these in a sedated and intubated adult patient (60% of marks)
A satisfactory answer required use of terms radiation, convection, conduction etc. in the
manner defined in the texts, rather than the layman’s use of the terms. Better answers
displayed understanding of the meaning, relative importance and mechanism of methods of
heat loss.
The second part of the question required application of these concepts in patients with artificial
airway and sedatives, particularly change in control of vascular tone and voluntary behavioural
control.
