Effect of environmental and behavioural factors on microbiological air quality of operating rooms

Introduction: An operating theatre (OT) is a very complex setup, which presents numerous challenges for both patients and health care providers. A safe OT environment decreases the susceptibility of to postoperative infections. Therefore, study was conducted determine microbiological air quality establishing baseline values assess concurrently effect behavioural factors in 46 OTs tertiary hospital. Materials & Methods: The were divided into two groups based on type flow: laminar diffuser (Group I) or conventional II). Two hundred thirty-eight samples collected with an active technique using sieve impactor, sampling at 100 L/minute. Statistical analysis Package Social Sciences (SPSS) Version 20 (IBM Corp., Armonk, NY). Results: In Group I diffuser, bacterial fungal during lean period environmental 47.78 colony forming units (CFM)/m3 0.24 CFU/m3, respectively. surgical 98.01 CFU/m3 0.40 same II 52.83 0.39 period, 80.06 period. Discussion: Both – temperature, humidity, percentage fresh circulation, door type, controlled entry, minimal opening proper attire seen contribute maintaining units.
