Efficacy of povidone-iodine in preputial antisepsis.

Wound infection after a surgical procedure is one of the main problems affecting the success of an operation. The prepuce is used in hypospadias surgery and in tissue defects in reconstructive surgery. The objective of this study is to determine the efficacy of povidone-iodine and surgical soap in preputial skin preparation. Ninety-four healthy children were divided into three groups. After obtaining preputial skin swabs, an application of povidone-iodine 10% was made and skin swabs were obtained after two and five minutes in group 1. An additional application of povidone-iodine after two minutes was made in group 2 and swabs taken. Group 3 received a local scrub with surgical soap and an application of povidone-iodine. Results showed that, despite painting with povidone-iodine and/or local cleaning with surgical soap, it is not possible totally to eradicate the micro-organisms in the prepuce. Surgical soap decreases the colony count, which can lead to increased effectiveness of povidone-iodine after painting. We recommend preoperative local cleaning with surgical soap before surgical painting.
