Warm blankets beat shivers before heart surgery
NCT ID NCT07505654
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using special thermal blankets before open heart surgery can help patients feel more comfortable and shiver less. 105 adults having their first open heart surgery were randomly given either a thermal blanket, a forced-air warming blanket, or a standard blanket. Researchers measured body temperature, shivering, and how warm and comfortable patients felt.
