An In Vitro Study on the Efficacy of Green Synthesized Silver Nanoparticles on Surgical Site Infections and Healings.

Background/

Objectives

The healing rate of wounds resulting from postoperative abdominal surgery interventions increases as the inflammation and infections in the wound are reduced. However, antibiotic resistance among microorganisms increases the incidence of surgical site infections (SSIs). Therefore, the need for new products that exhibit antimicrobial and anti-inflammatory activities, in addition to antibiotics, is increasing.

Methods

Silver nanoparticles (CO-AgNPs) were obtained using the green synthesis technique with Cydonia oblonga L. leaves, which constitute a significant amount of waste, and the effects of the obtained nanoparticles on in vitro wound healing were determined.

Results

It was observed that CO-AgNPs inhibited myeloperoxidase and collagenase, enzymes that negatively affect wound healing. Furthermore, they exhibited good antimicrobial activity against Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis, and Staphylococcus aureus, which are common hospital pathogens. The CO-AgNPs could exhibit enhanced wound-healing properties by inhibiting microorganisms.

Conclusions

It was clear that the development of new, environmentally friendly, and biocompatible products containing CO-AgNPs could be feasible, particularly for wound healing following infected abdominal surgery.
