Less is better? a retrospective chart review of in- hospital cardiac arrest patients

also negatively correlated with ventilator-free days (rs = -0.14, p = 0.029), ICUfree days (rs = -0.16, p = 0.01), and hospital-free days (rs = -0.19, p = 0.003). There was no association between the median or maximum storage duration of RBCs and in-hospital mortality (p = 0.751 and p = 0.75, respectively). After controlling for multiple confounders, including age, initial rhythm, time to return of spontaneous circulation, bystander CPR, the presence of shock, peak troponin, and lowest hemoglobin during TH, transfusion of RBCs during TH was no longer associated with a statistically significant increase in risk of in-hospital mortality (OR 3.22, 95% CI 0.75–13.69, p = 0.113). Conclusions: In patients having suffered sudden cardiac arrest and are undergoing treatment with TH, transfusion of RBCs is not independently associated with a statistically significant increase in risk of in-hospital mortality. Our current analysis may suggest a lack of power to detect this association.
