血管外肺水在危重患者中的预测价值

The Prognostic Value of Extravascular Lung Water in Critical Ill Patient

在危重患者的监测中,心肺功能的监测是最重要的。在许多危重患者的治疗过程中,治疗的首要目的是改善和维持器官的灌注,为了达到这个目的,就需要保证有一定的前负荷,这样就有肺水肿的危险,而肺水肿是危重患者的呼吸衰竭的原因。如何在既保证器官灌注基础上又不引起肺水肿一直是危重患者治疗上的一个难题,同时在早期预测危重患者预后上缺乏指标。近年来血管外肺水(EVLW)作为评价心肺功能的指标以及早期评价预后上的价值在临床上越来越得到广泛应用。

Cardiac and pulmonary monitoring is very important in critical ill patient, the first aim is to improve and sustain the perfusion of main organs. To obtain this subject, enough preload must be ensured, however, this will increase tile incidence of pulmonary edema which is the common reason of respiratory failure. It is always an intractable problem in the therapy of critical care to sustain the parfusion of main organ while not induce pulmonary edema, meantime, meanwhile, there is a lack of sensitive index to forecast the prognosis of critical ill patients. In recent years ,extravaseular lung water as an index to estimate the function of heart and pulmonary has been widely applied m clinic,and shown its important value in annraise prognosis.
