Background:
Acetaminophen (APAP) is widely used in the treatment of patients after surgery, but the prognosis of patients with coronary artery bypass grafting (CABG)-related acute respiratory distress syndrome (CABG-ARDS) is still unclear. This study aims to explore the role of APAP in the management of CABG related ARDS.
Methods:
We collected clinical data on patients with CABG-ARDS from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database. The primary outcome was early mortality after ARDS, and the secondary outcomes were length of hospital stay and duration of mechanical ventilation (MV). Multivariate logistic regression and Cox regression models were used for statistical analysis, and inverse probability processing weighting (IPTW), overlap weighting (OW) and propensity score matching (PSM) were used to explore the robustness of the outcomes.
Results:
A total of 5459 patients were enrolled in the analysis. Multivariate logistic regression analysis revealed that the 14-day mortality in APAP group was significantly lower than that in non-APAP group (0.5% vs. 2.7%, OR = 0.301; 95% CI, 0.170-0.531; P < 0.001). The APAP group also showed a significant advantage in Cox regression analysis (0.5% vs. 2.7%, HR = 0.329; 95% CI, 0.187-0.577; P < 0.001). IPTW, OW, and PSM analyses were conducted between the two groups, and the differences remained significant. These results were consistent in 30-, 60-, and 90-day mortality analyses. Meanwhile, exposure to APAP was associated with a shorter length of hospital stay and a reduced duration of MV (P < 0.001).
Conclusion:
The administration of APAP was associated with reduced early mortality in patients with CABG-ARDS, as well as shorter length of hospital stay and duration of MV.
