The results of this study suggest that preoperative warming can reduce rates of SSI after surgery .
OBJECTIVE To determine whether preoperative warming can reduce the risk of surgical site infection ( SSI ) after surgery .
BACKGROUND Intraoperative hypothermia is a risk factor for the occurrence of  SSI in patients after surgery .
However , the effectiveness of preoperative warming in reducing the incidence of the condition remains unclear .
Perioperative warming, oxygen, and Ilomedin on oxygenation and healing in infrainguinal bypass surgery.
BACKGROUND Perioperative adjuncts are utilized across surgical specialities with the goal of improving patient outcomes . High-dose oxygen and extended warming are shown to increase wound collagen deposition during abdominal surgery . Prostacyclin is shown to improve limb salvage and patency rate in infrainguinal bypass ( IIB ) surgery . This study evaluated the impact of these adjuncts on healing and perfusion post IIB surgery . METHODS This r and omized controlled study allocated patients undergoing IIB surgery into three treatment arms ( perioperative high-dose oxygen , extended warming , and a synthetic prostacyclin ) or a control group . The primary outcome was accumulation of hydroxyproline ( OHP , collagen surrogate marker ) as collected in polytetrafluoroethylene implants on day 5 . Secondary outcomes included levels of growth factors and cytokines , and tissue oxygenation of the wound and foot as measured by hyperspectral technology and ankle-brachial pressure index . Clinical outcomes were observed to day 30 , with long-term follow-up of 12 mo . RESULTS Seventy-one patients completed the study . Comparing treatment groups with the control at day 5 , there were no differences in OHP , growth factors or cytokines levels , or improvement in tissue oxygenation at the surgical incision . However , there was more flow to the foot ( HT-SUM ( % ) change ) in the Ilomedin group compared to control ( 0 % versus -14.6 % , P = 0.045 ) . HT-deoxy was higher at the peripheries in the oxygen and temperature groups , suggesting decreased tissue oxygenation . CONCLUSIONS The perioperative treatments did not dramatically improve oxygenation or healing of the surgical wound in IIB surgery ; however , Ilomedin may result in greater flow to the peripheries
