A randomized controlled trial of 1% aqueous chlorhexidine gluconate compared with 10% povidone-iodine for topical antiseptic in neonates: Effects on blood culture contamination rates

We conducted a randomized controlled trial in neonates with birth weight greater than or equal to 1,500 g that compared 1% aqueous chlorhexidine gluconate (CHG) with 10% povidone-iodine (PI) as a topical antiseptic. We found 1% CHG to be more effective than 1% PI in reducing blood culture contamination rates, and no contact dermatitis was observed.
