Skin antisepsis protocols for the collection of blood from donor dogs

Abstract

ABSTRACT: The objective of this study was to evaluate and compare the bactericidal efficacy of2% chlorhexidine surfactant solution + 70% alcohol and 2% chlorhexidine surfactant solution + 0.5% chlorhexidine-alcohol, and standardize skin antisepsis for blood collection from donor dogs. One hundred and twenty skin swabsof the jugular regions of 20 dogs were evaluated. Swabs were distributed into six treatment(T) groups according to the disinfectant used and removal or retention of local hair: T1involved neither antisepsisnorhair removal; T2comprised 2% chlorhexidine + 0.5% chlorhexidine-alcoholwithout hair removal;T3 comprised 2% chlorhexidine + 70% alcohol without hair removal; T4comprised hair removal but no antisepsis;T5comprised 2% chlorhexidine + 0.5% chlorhexidine-alcohol withhair removal; and T6comprised 2% chlorhexidine + 70% alcohol with hair removal. Antiseptic agents were continuously applied in a single direction for a total of 3 min. Use of antiseptics was effective with or without hair removal, resulting in the absence of bacterial growth. Complete efficacy of the technique used in this study may have been due to the increased antiseptic application time. In conclusion,the antisepsis protocols tested in this study can be safely used for the collection of blood from dogs; although,removal of hair prior to antisepsis is still recommended.
