121 - Evaluation of Microbial Contamination in Hospital, Clinic, Health Care Premises, etc

The Guide lines for the evaluation of the microbial environmental contamination in the operating rooms of hospital, clinic and health care premises are repported in the document of World Health Organisation (WHO), National Health Service (NHS).

96 - Subdivision of hospital operating department in different areas depending on the biological risk for staff and patients

The most advanced areas for the control of particulate and microbial contamination in the " contamination controlled " environments are undoubtedly space industry, electronics and pharmaceutical industries. The pharmaceutical industry is the one that comes closest to the hospital sector, at least from a microbiological point of view, and may therefore be useful to draw on its technological innovations in the field of contamination control and in particular to the Good Manufacturing Practice.

66 - Air sampling in Hospital

Microbial contamination monitoring in operating theatre of hospital The microbiological contamination in operating theatre is an important parameter to be considered to reduce / eliminate the risks of infections in hospital during surgery. The microbiological monitoring of this critical environment has two specific goals: A. to confirm the Heating Ventilation Air Conditioning (HVAC) system and the sterile unidirectional air flow are working regularly; B. to confirm the staff is following a correct aseptic protocol.

20 - Legionella aerosol monitoring

Legionnaires’ disease was first recognized as a result of an outbreak of acute pneumonia that occurred at the Convention of the American Legion in Philadelphia USA in 1976. The route of infection has been recognized as the inhalation of small aerosol containing bacteria of the Legionella sp into the lungs of the host animal. The bacterium primarily responsible for this disease is Legionella pneumophila sero-group 1 Pontiac. It can result in typical Legionnaires’ disease an acute pneumonia with low attack rate and relatively high fatality rate or Pontiac fever, a mild non-pneumonia infection with a high attack rate.

17 - Nosocomial Infections: Aspergillosis air sampling

Nosocomial-acquired aspergillosis typically occurs in the setting of treatment for leukaemia or other haematological malignancy. As Aspergillus species are easily found in the environment, it is accepted that aspergillosis disease can be a consequence of exogenous acquisition of the fungus.

13 - Microbiological Air Monitoring in Operating Room

The prime function of a “Ventilation System” or a “Heating Ventilation Air Conditioning System” (HVAC) in an operating theatre, intensive treatment units and isolation suites is to closely control the environment and air movement of the space that it serves in order to contain, control and reduce hazard to patients and staff from airborne contaminants, dust and harmful micro-organisms.

11 - Mycobacterium tuberculosis bioaerosol sampling

Mycobacterium tuberculosis is a very well known old enemy that after some decades of relative “sleeping” is now again a “new emerging” disease. The World Health Organisation (WHO) estimated more than 8 million new cases and 3 million deaths are occurring annually. The micro-organism is spread by the airborne transmission of droplets produced by infectious individuals while they are sneezing, speaking, laughing, coughing.

9 - Fungal Spore Control Ventilation (FSCV) in Hospital

The breathing of ambient concentration of airborne fungi for a normal person has no adverse effect on his health. The effects are adverse for the hospitalized patient with immune suppression: he is in fact susceptible to infections caused by naturally occurring airborne fungi that may grow at body temperature. The incidence of infections caused by fungi that were a few years ago considered only saprophytic has risen dramatically during the last decade.
