Despite the demonstrated effectiveness of the vaginal cleansing in the previous study, yet this has not been adopted within obstetric practice internationally and does not feature within the NICE Intrapartum guideline.7 This is may be due to concerns with exposure of the fetus to iodine-based substances, concerns with vaginal staining and allergy to iodine. Iodine is an antibacterial agent, but becomes inactive by the presence of blood may limit its use.
Chlorhexidine show greater reduction in skin flora after application compared with povidone-iodine agents (0.5 and 4%) respectively and has a greater residual activity after application than other preparations and (unlike povidone iodine) it is not inactivated by the presence of blood. Thus, there are a number of reasons to believe that vaginal cleansing with chlorhexidine would be an appropriate alternative to povidone iodine.8 There is one RCT comparing povidone iodine with chlorhexidine gluconate for vaginal cleansing at CS. This suggested that chlorhexidine may be superior, and further research was needed.9 Solutions that contain lower concentrations, such as chlorhexidine gluconate and acetate (0.05%) are usually well tolerated and may be used for vaginal preparation. With this preparation, there are no reported cases of allergy.8 Importantly, no safety concerns for the mother or baby have been identified with chlorhexidine gluconate used for vaginal cleansing.10

| Experimental: Chlorhexidine vaginal prep.arm Women in labor who will receive vaginal cleaning immediately before cesarean section using 50 ml of chlorhexidine gluconate 0.05% solution and standard abdominal scrub with chlorhexidine gluconate 4%. This concentration is indicated within the British National Formulary for swabbing in obstetrics. A swab soaked in the antiseptic will be used to clean the vagina for 30 seconds prior to CS at the time of urinary catheter insertion by long forceps.
After the CS procedure, the vagina is always cleaned of excess blood as with a dry swab. | Drug: Chlorhexidine vaginal prep.arm preoperative vaginal preparation |
| No Intervention: No vaginal antiseptic arm Women in labor who will receive abdominal scrub with chlorhexidine gluconate 4% only. Vaginal preparation is not including antiseptic or using normal saline only. |
