[Thermal comfort in perioperatory risk's evaluation].
Studies till now conducted about operating rooms' microclimate have been focused mainly on operators' thermal comfort, considering that uneasiness conditions may compromise their working performance. In last years, nevertheless, the anesthesiologic community recalled attention on patients' risks determined by perioperatory variations of normothermia, underlining the necessity of orientating studies to individuate microclimate characteristics act to guarantee thermal comfort of the patient too. Looking at these considerations, a study has been conducted in the operating rooms of the hospital-university Firm and the n.1 USL of Sassari, finalized, on one hand, to determinate microclimate characteristics of the operating blocks and to evaluate operators' and patients' thermal comfort, on the other to individuate, through a software simulation, microclimate conditions that ensure contemporarily thermal comfort for both the categories. Results confirm the existence of a thermal "gap" among operators and patients, these last constantly submitted to "cold-stress", sometimes very accentuated. So, we underline microclimate's importance in operating rooms, because there are particular situations that can condition perioperatory risks. Moreover it can be useful to integrate risk's classes of the American Society of Anestesiology (ASA) with a score attributed to the PMV/PPD variation, reaching more real operatory risk indicators.
