Effect of Colchicine on Perioperative Anti-inflammatory Organ Injury in Cardiac Surgery

Summary

All patients will be completed collection of demographic data, clinical data, and be observed for inflammatory organ damage, oxygenation index or SpO2/ FIO2, WBC, NEU, interleukin-1β, interleukin-6, interleukin-8 (IL-1β/6/8), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), procalcitonin (PCT), myoglobin (Myo), creatine kinase-MB (CK-MB), high-sensitivity cardiac troponin T (hs-cTnT), neutrophil elastase (NE), myeloperoxidase (MPO), APACHE II score, alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin, Murray lung injury score, serum creatinine, eGFR, mechanical ventilation time, ICU length of stay, drug-related gastrointestinal reactions, and 30-day and 90-day all-cause mortality, among other indicators.
