Abstract

Aims and Objectives:

The aims of this study were to evaluate the presence of Staphylococcus aureus and Escherichia coli, in polyglycolic acid (PGA) 4-0 and silk sutures, with or without hyaluronic acid (HA) treatment.

Materials and Methods:

This in vitro study measured S. aureus and E. coli growth on PGA and silk sutures, through incubation in agar media for 24 h. The suture length was 10 cm and divided into three parts: A (8 h), B (16 h), and C (24 h), which were observed every 8 h, followed by suspension on a microscopic slide. This was repeated thrice. The number of S. aureus and E. coli cells was recorded and compared between the suture types.

Results:

The mean S. aureus colony forming units (CFUs) differed at each time point between non-HA and HA-PGA sutures (P = 0.0016), with a greater number of CFUs on non-HA-PGA. The mean S. aureus CFUs were significantly higher on non-HA silk than on HA-silk sutures (P = 0.008). There was a significant increase in E. coli CFUs on non-HA silk than on HA-silk sutures (P = 0.008). E. coli CFUs were higher on non-HA-PGA than on HA-PGA sutures (P = 0.006). We performed repeated measures two-way ANOVA (SPSS version 13.0) for comparison between group factors and time points and Posthoc analysis using independent samples t-test.

Conclusions:

HA reduced wicking in both PGA and silk sutures.
