Clinical effects of reverting from leukoreduced to nonleukoreduced blood in cardiac surgery.

Full Abstract

BACKGROUND:
A reduction in postoperative length of stay (PLOS) was recently demonstrated with the use of leukoreduced (LR) blood in cardiac surgery patients compared to a historical cohort who received non-LR blood. Follow-up data are now presented in a similar population after a 12-month period in which LR blood was no longer routinely used.

STUDY DESIGN AND METHODS:
This is an extension of a study in which all patients admitted over a 12-month period for open heart surgery were given LR blood (Group 2) and were compared against a historical cohort given non-LR blood (Group 1). This study measures the outcomes of a new cohort of patients admitted during a 12-month period where LR blood was no longer routinely used (Group 3).

RESULTS:
PLOS increased in patients who received transfusions with non-LR blood (Group 3, n = 595) versus patients with LR blood (Group 2, n = 645; p = 0.045 by nonparametric rank U test). Mean PLOS increased from 9.5 days (95% confidence interval [CI], 8.9-10.0) to 10.8 days (95% CI, 10.0-11.6). In comparison, an earlier cohort who received non-LR blood (Group 1, n = 501) had a mean PLOS of 10.1 days (95% CI, 9.4-10.7). With the exception of decreased red blood cell (RBC) usage in Group 3, there were no significant differences in non-RBC blood usage, estimated blood loss, bypass time, mediastinitis rates, operative mortality rate, or overall mix of cases.

CONCLUSIONS:
The use of non-LR blood for cardiac surgery was associated with an increased PLOS compared to the use of LR blood and supports our previous demonstration of the benefits of LR blood in cardiac surgery.
