Different surrogate markers of tissue oxygenation have been used to explore the relationship between duration of RBC storage and their efficacy in restoring optimal tissue oxygenation.
To examine the relationship between duration of RBC storage and changes in S1P levels post-transfusion, data were analysed by weighted least-squares linear regression analysis with the weights inversely proportional to estimates of error variance.
Vamvakas and Carven [ 18] investigated the association between the duration of storage of transfused RBCs and postoperative infection following coronary artery bypass graft surgery.
Thus, we considered these covariates (creatinine level, gestational age at inclusion, transport duration, and duration of storage between collection and analysis) to be potential confounders.
However, duration of storage did not differ between the treatment groups.
The overlap between the 2 cohorts in the distributions of duration of storage was limited, so that the estimate of the influence of storage duration is mostly based on subjects from Eden cohort for durations shorter than 24 h, and on subjects from Pélagie cohort for durations of 24 h or more.
The CMV IgG levels did not appear to be affected by the duration of storage of the serum samples and no significant correlations between CMV IgG or EBV IgG level and duration of storage were found.
The term age refers to the actual duration of storage, while maturity expresses the degree to which chemical changes occur during storage.
Tr. bactrae failed to emerge even after the shortest duration of storage of 10 days.
