Impact of brief prewarming on anesthesia-related core-temperature drop hemodynamics microperfusion and postoperative ventilation in cytoreductive surgery of ovarian cancer: a randomized trial

摘要

BackgroundGeneral (GA)- and epidural-anesthesia may cause a drop in body-core-temperature (BCTdrop), and hypothermia, which may alter tissue oxygenation (StO2) and microperfusion after cytoreductive surgery for ovarian cancer. Cell metabolism of subcutaneous fat- or skeletal muscle cells, measured in microdialysis, may be affected. We hypothesized that forced-air prewarming during epidural catheter placement and induction of GA maintains normothermia and improves microperfusion.
