From: High dose statin prophylaxis in cardiopulmonary bypass related surgery: clinical utility
Effect of cardiac surgery with cardiopulmonary bypass on patient’s serum IL-8. Blood samples were collected from the patients preoperatively (as baseline), 5 min, 4 h post cross-clamp removal in both the control arm (n = 15) and the investigation arm (n = 15). Columns indicate the median and error bars indicate the standard error of the mean. There were statistically significant difference between the two groups at baseline, *p = 0.035 and at 4 h post cross-clamp removal, **p = 0.036
