Analisys of local thermal discomfort in surgical environments with the use of mannequins, measurement of environmental variables and subjective evaluation. Ambient. constr.

In the evaluation of thermal comfort in indoor environments it is not enough to perform the analysis of the comfort conditions for the body as a whole, since it is also necessary to examine the conditions of local thermal discomfort. In complex environments, such as surgical environments, where team members occupy different positions in the surgical environment and perform distinct activities, an analysis of the conditions of local thermal discomfort becomes even more necessary. This study analysed local thermal discomfort conditions due to radiant temperature asymmetry, vertical differences in air temperature and the risk of draughts through the use of mannequins, measurements of environmental variables and subjective evaluation. Results of the subjective evaluation showed dissatisfaction levels of up to 35% of anaesthesiologists and nurses regarding draughts, and up to 85% of surgeons regarding the heat of the surgical focus. Similar results were obtained from the measurement of environmental variables and the use of mannequins. These results confirm the great difficulty of providing thermal comfort in such an environment. However, the use of different analysis tools can assist in finding the best possible thermal comfort conditions for all members of the surgical team.
