Core Tip
Core Tip: This study demonstrates that the preoperative shock index (SI), calculated as heart rate divided by systolic blood pressure, is a powerful predictor of postoperative complications and long-term survival in patients undergoing splenectomy for traumatic splenic rupture. By integrating SI with key clinical variables, we developed a prognostic model with strong discriminative performance. An SI threshold of 1.15 effectively identified high-risk patients. These findings support SI-based early risk stratification and provide evidence for optimizing surgical decision-making and perioperative management.
