Abstrakt:	Background: Preoperative showering with antiseptic skin cleansers is common in elective operations, although the value of this procedure in reducing surgical wound infections has not been established. The authors designed a prospective study to assess the influence of povidone-iodine preoperative showers on skin colonization in elective plastic surgery procedures. Methods: Patients older than 18 years scheduled for elective and clean plastic surgery procedures on the thorax or abdomen were assigned randomly to the povidone-iodine group (n = 57) or to a control group (n = 57). Patients allocated to the povidone-iodine group took a shower with liquid detergent-based povidone-iodine 10% 2 hours before surgery. For the control group, no special instructions for showering were implemented before surgery. Quantitative skin cultures were obtained just before the preoperative scrub in the operating room. Samples were plated on hypertonic mannitol agar, blood agar, Sabouraud agar with chloramphenicol, and eosin-methylene blue agar. Samples were collected and processed, and results were assessed by blinded investigators. Results: Staphylococcal skin colonization was significantly lower in the povidone-iodine group (p < 0.001). No microorganism growth was observed on 33 percent of the postshower skin cultures from patients in the povidone-iodine shower group compared with 0 percent of the cultures from patients in the control group. Colonies of fungi and enterobacteria were recovered in small amounts in both groups, and povidone-iodine showers did not significantly reduce skin colonization by these microorganisms. Conclusion: Single preoperative povidone-iodine showers are effective in reducing staphylococcal skin colonization before elective clean plastic surgical procedures on the thorax and abdomen.
