It is very uncertain whether chlorhexidine gluconate changes adverse events (maternal) ‐ skin irritation or allergic skin reaction compared with povidone iodine (very low certainty).
Chlorhexidine dressing following alcohol cleansing showed no clear difference in sepsis without a source compared with polyurethane dressing following aqueous povidone‐iodine cleansing (moderate certainty).
Chlorhexidine dressing following alcohol cleansing showed no clear difference in catheter‐related blood stream infection compared with polyurethane dressing following aqueous povidone‐iodine cleansing (moderate certainty).
Chlorhexidine dressing following alcohol cleansing probably leads to lower catheter colonisation compared with polyurethane dressing following aqueous povidone‐iodine cleansing (moderate certainty).
Chlorhexidine dressing following alcohol cleansing probably leads to higher adverse effects: contact dermatitis compared with polyurethane dressing following aqueous povidone‐iodine cleansing (moderate certainty).
