OBJECTIVE: To compare the effect on Total Aerobic Count (TAC) of application of Isopropyl alcohol, Chlorhexidine, and povidone iodine plus alcohol prior to venipuncture and development of phlebitis in children admitted at a tertiary hospital.

METHODS: A prospective randomized clinical trial in a tertiary hospital in Quezon City. A total of 129 patients one-year old and above with physician orders for IV insertion and extractions. Pre and post swabbing of the venipuncture site was done and placed on a blood agar plate. The three antiseptic solutions were applied over the venipuncture site and swabbed and placed on the agar plate. The primary outcome measure was the TAC in each blood agar of the tested antiseptic solution and correlation to developing phlebitis.

RESULTS: The CFU/mL after disinfection was significantly different between groups, with the lowest CFU/mL observed among patients disinfected with Chlorohexidine. Phlebitis was only noted in the alcohol group. No reactions were observed from patients who were disinfected with povidone iodine and chlorohexidine.

CONCLUSIONS: Single application of Chlorhexidine is the optimal method to be used as antisepsis prior to procedures like venipuncture. However, the use of povidone iodine plus 70% isopropyl alcohol also has comparable effect to Chlorhexidine.
