Background and Aim: Skin antisepsis plays a crucial role in pre-operative skin preparation, with chlorhexidine gluconate and alcohol being historically the preferred choice. However, concerns have risen regarding the development of bacterial resistance to chlorhexidine. Polyhexamethylene biguanide (PHMB) combined with Tris-ethylenediaminetetraacetic acid (Tris-EDTA) has recently emerged as a skin and wound antiseptic. This study aimed to compare the antibacterial efficacy and local safety of 2% chlorhexidine gluconate with 70% alcohol (CG+Alc) and 0.3% PHMB with 6% Tris and 1.86% EDTA (PHMB+Tris-EDTA) for pre-operative skin preparation in dogs.
Materials and Methods: Twenty-four adult dogs underwent aseptic preparation on both sides of their ventral abdomens, with one side receiving CG+Alc and the other side receiving PHMB+Tris-EDTA, assigned randomly. Skin swab samples were collected pre-antisepsis and at 3-, 10-, and 60-min post-antisepsis to quantify bacterial colony-forming units (CFUs). Local skin reactions (erythema and edema) were evaluated after hair clipping, pre-antisepsis, and at 3-, 10-, 30-, and 60-min post-antisepsis.
Results: There was no significant difference in bacterial CFU counts between the two antiseptic groups pre-antiseptic. Both solutions significantly reduced CFU counts (p < 0.05) at all post-antisepsis sampling times compared with pre-antisepsis. However, dogs treated with PHMB+Tris-EDTA showed a significantly higher incidence of edema at 10 min (p = 0.02) and 30 min (p = 0.003) and a higher incidence of erythema at 10 min (p = 0.043) post-antisepsis compared with CG+Alc. No skin reactions were observed in either group at 60 min post-antisepsis.
Conclusion: CG+Alc and PHMB+Tris-EDTA reduced bacterial counts in pre-operative skin preparation in dogs. However, acute transient skin reactions were observed more frequently following the application of PHMB+Tris-EDTA.
