A comparison of chlorhexidine and povidone-iodine solutions in neonatal intensive care units.

Abstract

BACKGROUND:

Povidone-iodine (10%; PI) and 2% chlorhexidine in 70% isopropyl alcohol (CHG-IA) solutions are among the most widely used disinfectants in the neonatal intensive care units. This study compares the use of these disinfectants and helps decide which is superior to the other for neonatal use.

METHODS:

All term and preterm infants born and hospitalized in Bursa Uludag University Hospital between July 2018-March 2020 were included. The infants were randomized into two disinfectant groups before birth. The application site was cleaned with the assigned disinfectant before intervention. The infants were screened for rates of neonatal sepsis, thyroid-stimulating hormone (TSH) levels, free thyroxine (fT4) levels, skin reactions to the assigned solution, and acute neurological side effects.

RESULTS:

We enrolled 208 term and preterm infants (PI:104 vs. CHG-IA: 104) in the study. The prematurity rates were identical (PI: 74.0%; CHG-IA: 72.1%; p = 0.755). Neonatal sepsis rates among these groups were not statistically different (PI: 8.7%; CHG-IA: 4.8%; p = 0.406). The median TSH value of the PI group was high (4.05 mIU/L) in comparison with that of the CHG-IA group (3.09 mIU/L; p = 0.016). No cutaneous or neurological side effects were recorded in patients treated with CHG-IA solution.

CONCLUSIONS:

Although these two solutions were equally protective against infections, the CHG-IA solution was a better alternative to PI for neonatal use. Considering that the PI solution may be responsible for impaired thyroid function, the CHG-IA solution is a good alternative because it provides sufficient protection with a safer adverse effect profile.
