Study on the relationship between postoperative delirium and blood ascorbic acid levels in patients undergoing cardiovascular surgery - Study on the relationship between postoperative delirium and blood ascorbic acid levels in patients undergoing cardiovascular surgery

We enrolled 100 patients, and the data of 98 patients were analyzed. Results: In total, 31 patients developed delirium, while 67 did not. Preoperative plasma ascorbic acid levels did not differ between the non-delirium and delirium groups. Postoperative plasma ascorbic acid levels were significantly different between the groups. Conclusion: In patients who undergo cardiovascular surgery with CPB, lower postoperative plasma ascorbic acid levels may be associated with the development of delirium.
