Active warming systems to maintain perioperative normothermia in hip replacement surgery.

摘要

In response to Moretti et al.'s article 'Active warming systems to maintain perioperative normothermia in hip replacement surgery: a therapeutic aid or a vector of infection?', the National Institutes of Health (NIH) used computational fluid dynamics (CFD) and particle-tracking methodology to assess whether a forced-air patient-warming system increases the risk of nosocomial infections at the surgical wound site. NIH analysed laminar airflow disruption and room airflow patterns to determine the effect of squame impingement from personnel surrounding the operating table as a source of surgical wound infection.
