危重症患者多伴有器官功能障碍和全身循环状态不稳定。液体治疗需要根据患者状态随时进行调节,在循环状态、脏器功能、治疗需求之间寻求平衡,并在连续监测的基础上,借助多种容量监测工具及重要指标衡量患者液体复苏反应性、实时观察机体的反应,正确判断患者的容量状态,迅速作出相应调整;同时选择合适的液体类型,根据个体化的原则作出最佳决策,使患者受益最大化,达到精细化容量管理要求。
Critical patients always have complications of multiple organ dysfunction syndrome and unstable circulation. Fluid therapy must be timely regulated according to the status of critical patients and accomplish a balance among organ function, circulation status and therapy purpose. On the basement of continuous monitoring by different medical equipments such as Swan -Ganz catheter,pulse indicator continuous cardiac output device and transthoracic echo and by important indices to justify the responses of fluid recovering, real -time data of patient should be collected and analyzed to adjust fluid therapy, fluid types should also be chosen according to the response of critical patients. Strict fluid therapy established on an individ- ualization basis could benefit critical patients mostly.
