心功能障碍是外科围手术期最常见的并发症之一，也是导致外科病人病死率高、住院时间长、住院费用高的主要原因之一。因此，早期识别、干预及治疗非常重要。诱发围手术期心功能障碍的原因非常复杂，如不恰当的液体治疗、心律失常、心血管事件、高血压、麻醉、手术应激等。围手术期心功能障碍的处理除了积极评估围手术期心血管风险外，还应该征求外科、心脏内科和重症监护等多学科人员的综合意见，并将病人的液体治疗、抗心律失常、心血管事件处理、外科手术术式、麻醉药物及方式等个体化，形成围手术期病人的的最优化治疗，提高围手术期安全性，减少并发症并改善预后。

Abstract    Cardiac dysfunction is one of the most common complications of surgical patients during perioperative period，which lead to higher mortality rate，longer duration of hospitalization and more medical expenses. Thus，it is very important for early identification of high-risk patients，early intervention and early treatment. However，the risk factors of cardiac dysfunction during perioperative period is very complex，such as inappropriate fluid therapy，arrhythmia，hypertension，cardiovascular events，anesthesia，operation stress，etc. The treatment of cardiac dysfunction during perioperative period should follow the comments of multidisciplinary staff from surgery，cardiology and critically care，which should include the cardiovascular risk assessment. In addition，the patient's fluid and anti-arrhythmic therapy，cardiovascular event handling，operation，anesthesia and haemostatic scheme should be provided individually. Thus，the treatment can be optimized and improve security, reduce complications and improve the prognosis of patients.
