Efficacy of povidone-iodine in preputial antisepsis

Area of Science:

• Surgical preparation
• Infection control
• Microbiology

Background:

• Surgical site infections are a significant complication.
• The prepuce is a valuable graft source in reconstructive surgery, particularly for hypospadias repair.
• Effective pre-operative skin preparation is crucial for minimizing infection risk.

Purpose of the Study:

• To evaluate the efficacy of povidone-iodine and surgical soap in preparing preputial skin for surgery.
• To compare different pre-operative skin preparation protocols.

Main Methods:

• Ninety-four healthy children were enrolled and divided into three groups.
• Group 1: Povidone-iodine 10% application with swabs taken at 2 and 5 minutes.
• Group 2: Povidone-iodine 10% application with an additional application after 2 minutes, followed by swabs.
• Group 3: Surgical soap scrub followed by povidone-iodine application.

Main Results:

• Neither povidone-iodine nor surgical soap completely eradicated prepuce microorganisms.
• Surgical soap significantly reduced microbial colony counts.
• Combining surgical soap with povidone-iodine showed enhanced antiseptic effect.

Conclusions:

• Complete microbial eradication from preputial skin is not achievable with current methods.
• Preoperative cleansing with surgical soap is recommended to reduce microbial load before povidone-iodine application.
• This approach may improve surgical outcomes by reducing infection risk.
