Abstract
Objectives: To explore the characteristics of cytokine storm in patients with septic shock after abdominal surgery, examine its relationship with clinical data, and determine intervention timings. Materials and Methods: We prospectively observed a cohort of patients with abdominal infection admitted to the surgical intensive care unit (ICU) after surgery (shock group). A control group of healthy individuals was used for comparison. Plasma samples and clinical data recorded at 0, 12, 24, 48, and 72 h after surgery were collected. Cytokines (tumor necrosis factor-α, interleukin [IL]-6, IL-8, IL-10, monocyte chemotactic protein [MCP]-1, IL-1 β, interferon-γ, IL-12p70, MCP-1α, IL-4, IL-2, and IL-13) were detected using the Luminex® technique. Results: Concentrations of most cytokines were significantly higher in the shock group. When a cytokine storm intensity curve was considered with the vasopressor dependency index and a Sequential Organ Failure Assessment (SOFA) score, time point of maximum cytokine storm intensity was earlier than that of the maximum vasopressor dependency index and SOFA score in the shock group. Conclusions: Cytokine storm occurred in patients with septic shock shortly after the abdominal surgery and may be a main mechanism leading to septic shock. Cytokine storm interventions should ideally be initiated within 24 h after surgery and be guided by cytokine storm biomarkers.
