Level 2: Mid-level evidence
A systematic Cochrane review of seven randomized trials evaluated the use of plastic adhesive drapes (through which an incision is made) in 4,195 patients who were undergoing any type of surgery (Cochrane Database Syst Rev. 2007:CD006353). Surgical-site infection occurred in 13.8% of the adhesive-drape patients compared with 11.2% of patients on whom no drape was used, based on a meta-analysis of five trials with 3,082 patients. There were no differences in the rate of surgical-site infection comparing the use of iodine-impregnated drapes vs. no drapes in an analysis of two trials with 1,113 patients. There were also no differences in the length of hospital stay, based on two trials with 603 patients.
