(American Society of Anesthesiologists) Body temperature decreases during the first hour of surgery, even when patients are actively warmed with forced air, reports a new study published in the February issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists. Furthermore, patients who experience the most hypothermia are more likely to require blood transfusions.
