Antimicrobial ventilation tubes Activent
Activent antimicrobial ventilation tubes represent a new generation of tympanostomy tubes. These are the first ventilation tubes with an antimicrobial coating, which effectively inhibits the growth of bacteria that contribute to the development of secondary infections and otorrhea in the postoperative period.
Activent antimicrobial ventilation tubes represent a new generation of tympanostomy tubes. These are the first ventilation tubes with an antimicrobial coating, which effectively inhibits the growth of bacteria that contribute to the development of secondary infections and otorrhea in the postoperative period.
Activent tubes are made of silicone or fluoroplastic impregnated with silver oxide. Antimicrobial coating of tubes has a proven bactericidal / bacteriostatic effect. During a microbiological study in a wide variety of bacterial cultures, including the most common causative agents of middle ear infections, a clean zone of inhibition of bacterial growth was observed around the Activent tubes. In a similar study of other ventilation tubes, a similar zone was not observed.
Tubes with an antimicrobial coating of Activent contribute to the improvement of tympanostomy outcomes, which is confirmed by research data. Ventilation tubes are made of silicone or fluoroplastic in versions for short - term or long - term use depending on the needs of the patient.
During microbiological research in a bacterial culture around the Activent tubes, a clean zone of inhibition of bacterial growth was observed.
Proven reduction in the frequency of otorrhea in the postoperative period.
Clinical studies confirm a significant decrease in the frequency of otorrhea in the postoperative period when implanting ventilation tubes of Activent with an antimicrobial coating in comparison with conventional tubes.
In a double - blind, multicenter study of otorrhea frequencies in the postoperative period, it was almost half lower when implanting ventilation tubes with an antimicrobial coating of Activent compared to conventional tubes. With the exclusion of the first week after surgery, this difference is even more significant: the frequency of otorrhea during implantation of conventional tubes was almost three times higher than during implantation of Activent tubes.
