Intensive Insulin Therapy and Glycemic Control to Alleviate Acute Lung in Jury in Cardiac Surgery under Cardiopulmonary Bypass.pdf

1、Aim and objective Insulin has been shown to have anti-inflammatory effects and also reducingthe systemic inflammation during cardiopulmonary bypass (CPB), whereashyperglycemia is known to increase the proinflammatory cyt

2、okines. In thisstudy we aimed to assess the effect of Intensive Insulin Therapy(IIT) oncardiopulmonary bypass induced acute lung injury during cardiac surgeries.
　　 Methods Patients (n=40) undergoing elective cardiac

3、 surgery with medianstemotomy under cardiopulmonary bypass were selected and wererandomly divided int0 2 groups, group C and group T. Group C (n=20) wasthe control group of the study and did not receive any intensive ins

5、-alpha, Neutrophil Elastase, and Myeloperoxidase levels weremeasured at different timing point.
　　 Results Bio markers levels were found to be lower in group IIT compared to groupC. There was a significant decrease i
