CLINIC EFFICACY OF HYDROGEL WITH IONIC SILVER (SILVERCARE ®) IN CONTROL AND HEALING OF INFECTED WOUNDS

Abstract

Objective: to determine the clinical efficacy of the ionic silver in hydrogel (SilverCare ®) in patients with acute or chronic bacterial critical colonization with wounds or infected wounds that have been operated in the service of Cardiovascular Surgery of the Hospital Universitario de Caracas, between the months of July and December 2011. Method: a total of 34 patients with positive bacteriological studies, included 25 patients between 18 and 70 years, operated by central or peripheral heart disease presenting with acute or chronic wounds with critical colonization or bacterial infection registered by culture of drainage. Results: of 25 patients, 5 were patients with cardiac surgery, undergone
mainly myocardial revascularization surgery complicated with saphenectomy or sternal wound infection, and 20 patients with postoperative peripheral vascular surgery (vascular injury by firearm scan 15 patients, other peripheral surgeries 5 patients). There was a total of 25 results of positive cultures for the following germs: Escherichia coli (8 cases-32%), Acinetobacter baumannii (4 cases-16%), S. aureus aureus Methicillin resistant (4 cases -16%), Psedomona aeruginosa (3 cases-12%), multidrug-resistant Acinetobacter SP (1 case-4%), Enterobacter agglomerans (case 1-4%), Klebsiella S.P.P. (case 1-4%), two or more germs (3 cases-12%). Found multi-resistant bacteria in 10 cases (40%). It was determined a reduction of more than 25% of the diameters of the wounds a fourth week of treatment in 23 cases (92%), infection control in 24 cases (96%), in addition to eliminating the pain and smell in 96% of cases, decrease in the amount of exudate by 88%. There was no recurrence of the infection in the wound to 60 days of follow-up. Conclusion: is confirmed the clinical efficacy of the use of hydrogel with silver (SilverCare®) in the control of infection and scarring in patients with wounds infected with little to moderate exudate, considering that the reduction of the speed of healing was due to the Hydrogel and control of infection to the Ionic silver.
