[Prevention of infections under anesthetic breathing with breathing filters: concerted recommendations of the Deutsche Gesellschaft für Krankenhaushygiene e.V. (DGKH) and the Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin e.V. (DGAI)].

An interdisciplinary working group from the German Society of Hospital Hygiene (DGKH) and the German Society for Anesthesiology and Intensive Care (DGAI) worked out the following recommendations for infection prevention during anesthesia by using breathing system filters (BSF). The BSF shall be changed after each patient. The filter retention efficiency for airborne particles is recommended to be >99% (II).

[HME filter versus patient-related replacement of tubes from the ventilation circuit for anaesthesia: a cost-benefit analysis].

Procedure-related costs were calculated for an operating theatre with 10 operating rooms. The variable parameter was the different hygiene regimens for the preparation of the anaesthesia circuit. In April 2003 a change was made for the whole anaesthesia area.

[The effects of active and passive humidification on ventilation-associated nosocomial pneumonia].

Study Objective: Airway humidification of ventilated patients in an intensive care unit may be established by heated humidifying systems (active) or by the means of a (passive) heat and moisture exchange filter (HMEF). There is a controversial discussion about the influence of the type of humidification on the rate of ventilator-associated pneumonia (VAP). Among 3,585 patients both methods were tested over a period of 21 months in an open, non-randomized cohort study.
