简要总结
Despite completion of more than 9 million procedures each year in France, the best antiseptic solution to be used for preparing the skin to reduce risk of surgical site infection (SSI) remains unknown. 2% Chlorhexidine gluconate (CHG)-alcohol is superior to Povidone Iodine (PVI)-alcohol for short term vascular catheter care (Mimoz O, Lancet 2015; Pages J, Intensive Care Med 2016), but studies comparing both antiseptic solutions for clean-contaminated surgical procedures led to conflicting results.
The present study will be the first large scale multicenter randomized controlled trial adequately powered to compare efficacy and safety of CHG-alcohol over PVI-alcohol in reducing SSI after clean surgery.
A clean surgery was chosen because pathogens involved in SSI mostly originate from skin. Therefore, optimisation of skin disinfection before surgery has the potential to reduce the incidence of SSI. Cardiac surgery was chosen because SSI may be severe, diagnosis of SSI is easy to monitor and to define and infections arise earlier than other frequent clean surgeries using implants such as orthopaedic or vascular surgery.
The incidence of reoperation for any purpose will be used as the main objective because there are easy to track and define and are less susceptible to interpretation in an open trial than superficial SSI. According to CDC criteria, patients will be monitored up to Day 90 because mediastinitis after cardiac surgery may occur after the usual 30-day SSI surveillance period.
