[The activity of the "Hygrobac DAR 352" filter in resuscitation patients]. / Riscontro dell'attività del filtro "Hygrobac DAR 352" nei pazienti in rianimazione.

The Authors clinically evaluated the efficacy of the "Hygrobac DAR 352" filter as an antibacterial barrier in a group of patients during mechanical ventilation. After 24 hours of IPVV, a cultural sample has been taken on both sides of the filter introduced in the breathing circuit (patient's side; ventilator's side). While bacteria has been isolated on "the patient's side" of the filter, they were not present on the surface of the "ventilator's side" of the filter. Therefore, the Authors emphasize that the Hygrobac DAR 352 filter represents a good barrier against the passage of bacteria, as it avoids the contamination of the mechanical ventilator by keeping pathogenic organisms coming from patient's airways inside the filter itself.
