Timing of Redox Imbalances in Cardiac Surgery

Key Points

• The aim is to assess the timing and effects of redox imbalances on oxidative stress during cardiac surgery.
• Used EPR for perioperative reactive oxygen species (ROS) measurement.
• Evaluated oxidative stress levels preoperatively and during surgery.
• Administered vitamin C supplementation to assess its impact on ROS levels.
• Cardiac surgery patients exhibited increased oxidative burden before surgery.
• Perioperative oxidative stress levels worsened during the surgical procedure.
• Vitamin C supplementation significantly lowered perioperative ROS levels.
