Summary

This study looked at whether warming patients before digestive surgery helps keep their body temperature normal. 105 adults having cancer surgery were divided into three groups: one with standard blankets, and two using a forced-air warming system for 20 or 30 minutes. The study also compared a new skin thermometer to standard ones to see which is better at detecting low temperature.
