Microclimatic and Environmental Surveillance of Operating Theaters: Trend and Future Perspectives

Abstract

The health risk level in operating rooms is correlated to the safety levels of microclimatic parameters, thermal indices, anesthetic gases and microbiological parameters. The objective of this study was to estimate the staff and medical service management compliance with the suggestions resulting from monitoring. Methods: The environmental conditions of 38 different operating rooms in the Sicily region, Italy, from January 2011 to December 2020 were monitored. The results were compared with specific standards suggested by national and international laws and guidelines. Results: Almost all microclimatic and microbiological parameters were outside the limits. The monitoring of the anesthetic gases showed that 5.6% of sevoflurane measurements exceeded the limit values. Conclusions: Constant environmental monitoring is an essential element for maintaining optimal living conditions in the working environment. The compliance of staff with guidelines and rules is a fundamental parameter for achieving this objective.
