silver nanoparticles antimicrobial activity
Brief summary
The purpose of this study is to determine whether oral topic silver nanoparticles are effective to reduce potential pathogen microbial loads in mechanical ventilation patients.
Detailed description
All patients were performed with oral hygiene as recommended by the clinical practice guidelines for the prevention, diagnosis and treatment of pneumonia associated with mechanical ventilation. After that, placed the treatment of an innocuous gel compound with 12ppm of silver nanoparticles or gel alone according to randomization. Then obtain and plant samples taken before the treatment 6 hours after. Comparing the results of the baseline sample with the final.
Interventions
OTHERsilver nanoparticles
Allocation was randomized. Evaluate the effectiveness of silver nanoparticles incorporated into an innocuous gel and dished in oral mucosa surface to then compare with another innocuous gel without silver nanoparticles to reduce microbial colony forming units of pathogenic potential.
OTHERplacebo
Compare with another innocuous gel without silver nanoparticles to reduce microbial colony forming units of pathogenic potential using the same procedure to dished the gel.

| Compare Colony Forming Units after the intervention. Unique dosis. | Comparison of microbial colony forming units at 6 hr of treatment with gel application | Before oral hygiene in the intubated patient, it was taken with sterile swab, a saliva sample which was sown in dextrose Sabouraud agar and tryptone soya agar. 6 hours later, placement of the experimental gel, retook saliva sample with a sterile swab and they seeded in the same agars . Colony forming units were counted before and after the intervention using semi-automated colony counter . |
