“…In a study comparing 0.5% alcoholic chlorhexidine with 70% hydrated ethyl alcohol for skin antisepsis for neuraxial blocks, it was shown that 70% alcohol was more effective in reducing the number of colony forming units (CFU/cm²) after two minutes, and there was no difference between the two groups in terms of skin colonization at the end of the procedure. 14 To verify whether two applications of chlorhexidine/ethanol solution are more effective than one for skin disinfection before neuraxial anesthesia, the result showed that the application of chlorhexidine/ethanol once is sufficient to disinfect the skin for regional anesthesia, and that the 2 nd application may be delayed in an emergency situation, and this 2 nd application increases the risk of translocation of chlorhexidine to the subarachnoid space. 15…”
