These types of drapes have however been found to be inferior in preventing bacterial SSI, compared to newer drape types that incorporates an antiseptic iodine-complex into the drape adhesive, facing the skin (10, 11) This outcome might be explained by a drape-induced "greenhouse effect" supported by evidence of increased bacterial colonization-rate with the intraoperative use of non-iodine self-adhesive plastic drapes (12, 13). This effect may be a result of relative occlusion of the skin leading to an increase in skin hydration.(14) This increase in bacterial growth has never been demonstrated in iodine impregnated self-adhesive incision drapes (IIAD) and has been contradicted in studies reporting a reduction in re-colonization rate of skin bacteria on the abdomen when IIAD was compared to no draping and non-iodine drapes while other authors reported decrease in surgical wound contamination when IIAD was used preoperatively in abdominal surgery (3, 15)
