description BackgroundAcute respiratory distress syndrome (ARDS) continues to pose significant difficulties due to the scarcity of successful preventative and therapeutic measures. Recent clinical trials and experimental research have confirmed the lung-protective and anti-inflammatory properties of dexmedetomidine. The objective of this study was to examine the relationship between the use of dexmedetomidine and mortality outcomes in ICU patients with ARDS.MethodsThis study retrospectively examined data from the Medical Information Mart for Intensive Care (MIMIC) IV, focusing on individuals diagnosed with ARDS. The primary endpoint was the occurrence of death within 28 days after entering the ICU. To ensure a balanced cohort, we applied propensity score matching at a 1:1 ratio. Additionally, multivariable analysis was performed to mitigate the effects of confounding factors.ResultsIn this study, a cohort comprising 612 patients diagnosed with ARDS was investigated. Analysis using both univariate and multivariate Cox regression indicated significantly reduced 28-day and 90-day mortality rates in patients administered dexmedetomidine compared to those who were not given this treatment. Following adjustments for potential confounders using propensity score matching, these results were confirmed to be robust.ConclusionThe results indicate an association between the administration of dexmedetomidine and lower mortality rates among severely ill ARDS patients. However, this result should be interpreted with cause because of a lot of missing data of potential risk factors for clinical outcomes. Nonetheless, it is imperative to perform further randomized controlled trials to corroborate this finding.
