Relationship between High Red Cell Distribution Width and Systemic Inflammatory Response Syndrome after...

Area of Science:

• Cardiology
• Hematology
• Critical Care Medicine

Background:

• Cardiac surgery with extracorporeal circulation can trigger severe inflammatory response syndrome (SIRS).
• SIRS is associated with poor patient outcomes and lacks reliable predictive markers.
• Red cell distribution width (RDW) is a readily available hematological parameter implicated in inflammatory processes.

Purpose of the Study:

• To investigate the association between red cell distribution width (RDW) and the development of SIRS in patients undergoing cardiac surgery.
• To evaluate RDW as a potential predictive marker for SIRS following extracorporeal circulation.

Main Methods:

• Retrospective analysis of 1250 patients who underwent cardiac surgery with extracorporeal circulation.
• Comparison of RDW levels, clinical data, and outcomes between patients who met SIRS criteria (n=26) and a control group (n=26).
• Logistic regression analysis to determine the association between RDW and SIRS development.

Main Results:

• Patients who developed SIRS had significantly higher RDW levels compared to the control group (15.5±2.0 vs. 13.03±1.90, P<0.0001).
• Mortality was substantially higher in the SIRS group (76.92%) versus the control group (7.6%, P<0.005).
• High RDW (exceeding 13.5%) was significantly associated with an increased risk of developing SIRS (OR: 1.0-1.2, P<0.05).

Conclusions:

• Increased RDW is a significant predictor of SIRS development in patients undergoing cardiac surgery with extracorporeal circulation.
• RDW serves as a valuable and accessible tool for identifying patients at higher risk of SIRS.
• Early identification of high-risk patients via RDW can facilitate proactive management to mitigate postoperative complications and mortality.
