目前，尽管绝大部分接受大手术的病人死亡率很低，但随着有高术后并发症和死亡风险的所谓高危手术病人的增加，给围术期安全管理带来新的挑战。以病人为中心、价值医疗为基础的多学科专业团队高效协作是保障围术期安全的新举措。其中重症医学专业团队起着关键作用，能对高危病人进行风险评估、围术期器官保护、密切监测和特定的早期干预，以达到及时预防、早期识别、有效治疗术后并发症的目的，从而降低死亡风险与改善术后生活质量。

At present, although the mortality of most patients undergoing major surgery is very low, the increase of so-called high-risk surgery patients with high risk of postoperative complications and death brings new challenges to perioperative safety management. The efficient collaboration of multidisciplinary professional teams based on patient-centered and value-based medicine is a new measure to ensure perioperative safety. Among them, the critical care medical professional team plays a key role in risk assessment, perioperative organ protection, close monitoring and specific early intervention for high-risk patients, so as to achieve timely prevention, early identification and effective treatment of postoperative complications, and to reduce the risk of death and improve the postoperative quality of life.
