Summary

The aim of this study is to assess the effectiveness and safety of sivelestat sodium in preventing acute lung injury and/or acute respiratory distress syndrome (ALI/ARDS) following cardiac surgery, with the objective of providing evidence-based support for its clinical application.

Detailed description

This study is being performed as a randomized, placebo-controlled trial conducted in 442 patients who met the inclusion and exclusion criteria and were scheduled for elective cardiac surgery. Following informed consent, patients were randomly assigned to either the experimental group or the control group, with the study drug administered after transfer to the ICU post-surgery. In the experimental group, sivelestat was dissolved in 0.9% sodium chloride injection and diluted with 50ml of the same solution to achieve a dose of 4.8mg/kg/day; this mixture was then placed in a sealed package and administered intravenously at a rate of 0.2 mg/kg/h for seven consecutive days. The control group received an equivalent volume (50ml) of saline continuously administered intravenously at a rate of 0.2 mg/kg/hour. Demographic and clinical information, including admission diagnosis, underlying diseases, medical history, surgical history, details of the surgical procedure, postoperative complications, and in-hospital outcomes were collected from all participants. The primary outcome is the incidence of postoperative ARDS. Secondary outcome measures include data collection on the following parameters: elevated inflammatory response indices (WBC\>20×109/L; IL-6\>301.88mg/ml; CRP\>49.76mg/L; PCT\>2.18ng/ml) on postoperative days 1, 3, 5, and 7; APACHE II score; Murray lung injury score; incidence of severe pneumonia; mechanical ventilation-free rate at day 28; mortality rates at both day 28 and day 90. Adverse events such as liver injury, leukopenia, and thrombocytopenia resulting from sivelestat treatment were also monitored. Additionally,during the follow-up period, mortality within a 90-day period will be recorded.

Type	Name	Description
DRUG	Sivelestat	(1)Experimental group: Received intravenous sivelestat sodium admission to the ICU. Sivelestat sodium was dissolved in 0.9% sodium chloride injection and a one-day dose (4.8mg/kg) was diluted in 50ml of 0.9% sodium chloride injection, which was then sealed for continuous intravenous administration at a rate of 0.2 mg/kg/h for seven consecutive days.
OTHER	placebo	2)Control group: Receiving the same dose of placebo, 50 ml of saline, were administered intravenously at a rate of 0.2 mg/kg throughout the treatment period without any discernible impact on patient's regular treatment regimen.
