ABSTRACT
PURPOSE:
To investigate the bacterial growth in the surgical face masks used by patients who received intravitreal injections and study the effect of povidone-iodine on the periocular area (PA) of masks.METHODS:
Forty patients who attended for intravitreal injections were divided in those with less (<4 hours) and more (>4 hours) than 4 hours of mask use. Each group was divided depending on the application or not of povidone-iodine in the PA of the mask. Bacterial load was studied on PA and mouth area samples.RESULTS:
The bacterial load in the PA was higher in the >4 hours group compared with the <4 hours group (13.2 vs. 48.75 colony-forming units/µL; P = 0.03). The contamination in the PA significantly decreased after applying povidone-iodine in the >4 hours group (P = 0.01). The use or not of povidone-iodine was strongly correlated to a positive culture (OR = 9.0, P = 0.00. CI 1.63-49.44).CONCLUSION:
Surgical face masks worn for more than 4 hours present higher contamination in the PA than those with less use. Bacterial load in the PA is reduced with povidone-iodine on masks used for more than 4 hours. This contamination should be considered in the asepsis protocol of intravitreal injections.
