The microbiological

monitoring in Operating Theatre


The microbiological contamination in operating theatre is an important parameter to be considered to reduce / eliminate the risks of infections.

The microbiological monitoring of air and surfaces has two specific goals:

(a)  to be sure the Heating Ventilation Air Conditionment (HVAC) system and the sterile unidirectional air flow are working regularly;

(b) to confirm the staff is following the aseptic protocol.

The  “TRIO.BAS DUO” (ORUM INTERNATIONAL) for the Hospital sector has been development to reach the listed purposes. Air and surfaces are both involved.

The “TRIO.BAS DUO Operating Theatre” microbiological air sampler collects 1000 litres of air in less than 3 minutes.

The “TRIO.BAS Contact”  microbiological surface sampler is used by contact for 10 seconds on the surfaces  that are considered at risk for a possible contamination.
