Topical Application of Silver Nanoparticles and Oral Pathogens in Ill Patients

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: gel silver nanoparticles<br>topic gel silver nanoparticles 12 ppm | Other: silver nanoparticles<br>* 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.<br>|
| Placebo Comparator: placebo<br>topic innocuous gel | Other: placebo<br>* 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.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compare Colony Forming Units after the intervention. Unique dosis. | 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 . | Comparison of microbial colony forming units at 6 hr of treatment with gel application |
