Web6. nov 2024 · Anesthesia induction with propofol is known to cause a rapid and clinically important temperature decrease due to redistribution hypothermia, typically by about 1.5 °C . Ikeda et al. showed there is on average 0.7 °C less redistribution hypothermia when patients are induced with an inhalation induction rather than with intravenous propofol ... WebActive warming using forced air blanket before the induction of anesthesia reduced the incidence and degree of redistribution hypothermia in patients undergoing OPCAB. It is a … Web29. okt 2024 · An alternative method of minimizing redistribution hypothermia is to actively warm peripheral tissues before induction of anesthesia. Even just 30 min of forced-air “prewarming” increases peripheral tissue heat content to ≈69 kcal, and 1 h of prewarming transfers nearly 136 kcal .
