The effect of aspirin in transfusion-related acute lung injury in critically ill patients
Tuinman PR et al. – The findings suggest that aspirin did not protect against transfusion–related lung injury in this cohort of critically ill patients.
The authors performed a post-hoc analysis of a nested case-control study that had been undertaken in a tertiary referral hospital.
Transfusion-related acute lung injury cases were matched with controls (transfused patients not developing lung injury).
Of these 218 patients, 66 used aspirin (30%).
Use of aspirin did not alter the risk of transfusion-related acute lung injury after transfusion of platelets (OR 1.06, CI 0.59-1.91, p=0.85), plasma (OR 1.06, 95% CI 0.59-1.92, p=0.84), or red blood cells (OR 1.09, 95% CI 0.61-1.94, p=0.77).
Adjustment for confounding variables using propensity scoring also did not affect the risk of acquiring transfusion-related acute lung injury (p=0.66).
