Abstract

Background Effective skin disinfection before spinal and epidural anaesthesia is essential to avoid bacterial infection. Three disinfectants, Betadine, Cetavlon and a combination of Chlorhexidine, Cetrimide and Isopropyl alcohol are used in hospitals as skin disinfectant solutions. We compared the ability of these disinfectant solutions to reduce the bacterial skin flora prior to anaesthetic procedures.

Method 80 Pregnant women admitted to Castle Street Hospital for Women (CSHW) and De Soysa Maternity Hospital (DMH) who received epidural or spinal anaesthesia were studied. They were randomly assigned to receive skin preparation with Betadine, Cetavlon and the combined preparation. Two cultures were obtained from each subject; just prior to skin disinfection and immediately following disinfection. In-use test was performed to determine bacterial contamination of newly opened and multiple used bottles from each group.

Results The reduction in bacterial colony forming units (CFU) following application of disinfectant in all three groups were significant (p < 0.05). The reduction of bacterial CFU following skin preparation between the three groups was tested by one way ANOVA and found to be significant (P=0.018). Pair wise comparison among Reduction of skin flora by antiseptics showed highest reduction with the use of the combined preparation. None of the samples of disinfectants obtained from newly opened and multiple used bottles of antiseptics were contaminated.

Conclusion The combined preparation consisting of Chlorhexidine, Cetrimide and Iso propyl alcohol showed the best reduction of skin flora followed by Cetavlon and Betadine.
