SURVEILLANCE AND STERILISATION OF OPERATIon THEATRES

In the Developing World

In spite of brief stay of patients in the operation theatre (in majority of circumstances), the environment of operation theatre plays a great role in the onset and spread of infection because of a multifactor causation of infection. It is usually necessary to study the epidemiology of infection as a multidisciplinary approach. In resource poor circumstances as in most developing countries, work in isolation and few facilities to make any epidemiological surveys Many believe that routine Microbiological monitoring is most essential but in reality it is not practicable. But every hospital should pay good attention in proper maintenance of air conditioning plants, ventilator systems, and to have greater control on mechanisms and personnel involved in disinfection and sterilization of materials used in the theatres in operative procedures.

Operation theatres should be built with implementation of good civil Engineering standards.

OPERATION THEATRE – DISCIPLINE

1. Only people absolutely needed for an assigned work should be present.

2. People present in theatre should make minimal movements and curtail unnecessary movements in and out of theatres, which will greatly reduce bacterial count.

3. Air borne contamination is usually affected by type of surgery, quality of air which in fact depends on rate of air exchange.

All the persons including the least cadre of employers are partners in infection control and should be aware to comply with infection control regulations

4 Prompt disposal of Theatre waste out of the theatre is of top priority. Any spillage of Body fluids including Blood on the floors is highly hazardous and prompts the rapid multiplication of Nosocomial pathogens in particular Pseudomonas spp

SURVEILLANCE OF OPERATION THEATRE

Role of Microbiological Surveillance

The environments in the operation theatre are dynamic and subject to continuous change. Good infrastructures do not mean a safe environment as human make a greater difference in making the environment unsafe.

Microbiologists should be aware of organisms, sites and populations as surveillance cultures should be chosen carefully to allow meaningful interpretation of results.

Microbiologists should be familiar with the clinical techniques as those normally used for culturing clinical specimens may not yield correct result when applied to environmental specimens.

Sites and cultured reports should not be chosen as etiological sources in the present infections. Culturing unnecessary surface areas causes confusion and meaningful
