Efficacy, safety, and pharmacoeconomics of sivelestat sodium in the treatment of septic acute respiratory distress syndrome: a retrospective cohort study.

BACKGROUND

Acute respiratory distress syndrome (ARDS) is one of the most organ dysfunctions in sepsis. Although the development of therapeutic strategies such as protective mechanical ventilation technology has improved the mortality of ARDS patients, there is currently no effective drug for reducing the associated mortality. Our study aims to investigate the efficacy, safety, and pharmacoeconomics of sivelestat sodium in patients with septic ARDS, for providing the basis on clinical use of this drug.

METHODS

This was a retrospective study of 140 patients with septic ARDS. Clinical information including general conditions, mechanical ventilation time, drug cost parameters, and adverse reactions. The partial pressure of O2/fraction of inspired oxygen (PaO2/FiO2), acute physiology and chronic health evaluation score (APACHE II score) and sequential organ failure assessment (SOFA score) are for assessing the severity illness. To evaluate the efficacy of sivelestat sodium on septic ARDS patients by comparing length of mechanical ventilation and intensive care unit (ICU) hospitalization, cost of hospitalization and mortality between the two groups.

RESULTS

There were no significant differences in the incidence of organ failure, biochemical data, blood gas analysis, acute physiology and chronic health evaluation (APACHE II score), and SOFA score between the two groups on the day of admission. The PaO2/FiO2, APACHE II score, and SOFA score of the sivelestat sodium group were significantly better than in the control group (P<0.05). The length of mechanical ventilation, length of ICU hospitalization, and cost of ICU hospitalization were all lower in the sivelestat sodium group (P<0.05). No adverse events were reported during the study period.

CONCLUSIONS

Sivelestat sodium significantly improves the oxygenation in patients with septic ARDS, together with reducing mechanical ventilation, ICU hospitalization, and medical costs.
