Alterations in cardiac effort and oxygenation during shivering after cardiac surgery.
This study was undertaken to determine if shivering after cardiac surgery threatens stability during early surgical recovery. Twenty-six subjects were monitored for 6 postoperative hours to identify effects of increasing shivering severity on cardiac effort and peripheral oxygenation. Analyses show that there is an increase in effort and a decrease in tissue oxygenation with increasing shivering severity.
