Chlorhexidine Use in Pediatric Patients

Age-Based Recommendations

The American Academy of Pediatrics and other medical societies recommend chlorhexidine for skin antisepsis in children over 2 months, as it is safe and effective for routine use in this age group 2
The ESPGHAN/ESPEN guidelines state that the use of chlorhexidine in infants younger than 2 months cannot be recommended due to potential side effects 3
The FDA has not approved chlorhexidine products for children younger than 2 months of age, according to the Anaesthesia journal 1, 4, 5

Premature infants and very low birth weight infants face increased risks, including contact dermatitis, chemical burns, and systemic absorption, as reported in the Anaesthesia journal 1, 4, 5
Alcohol-based chlorhexidine preparations have caused burns in infants of 24-26 weeks' gestational age, highlighting the need for caution in this population 1, 4, 5
Infants less than 36 weeks' gestational age may have detectable chlorhexidine blood levels after topical application due to immature skin barrier function, according to the Anaesthesia journal 1, 4, 5

The Anaesthesia journal recommends allowing chlorhexidine solution to dry completely before proceeding with any procedure to minimize risk of complications 1, 4, 5
A single application of chlorhexidine is sufficient; repeated applications are unnecessary and may increase complication risk, as stated in the Anaesthesia journal 1, 4, 5

The Clinical Nutrition journal recommends 2% chlorhexidine in 70% isopropyl alcohol as the preferred formulation for skin antisepsis before invasive procedures in children over 2 months 3
For infants under 2 months, aqueous solutions of chlorhexidine may be considered to avoid alcohol-related burns, though efficacy is reduced, according to the Clinical Nutrition journal 3

Hypersensitivity reactions, including contact dermatitis, urticaria, and anaphylaxis, can occur at any age, as reported in the Anaesthesia journal 1, 4, 5
Most severe anaphylactic reactions have involved application to mucous membranes or use of chlorhexidine-impregnated devices, highlighting the need for caution, according to the Anaesthesia journal 1, 4, 5

The Anaesthesia journal notes that it is incorrect to assume chlorhexidine is contraindicated in all neonates, as it has been used safely in large trials and is commonly employed in NICUs 1, 4, 5
Alcohol-based preparations should be avoided in extremely premature infants (less than 26 weeks' gestation) due to burn risk, as reported in the Anaesthesia journal 1, 4, 5
Ensuring complete drying of chlorhexidine before procedures is crucial to prevent complications, according to the Anaesthesia journal 1, 4, 5
