ABSTRACT
Pediatric acute respiratory distress syndrome(PARDS)is a pulmonary inflammation syndrome caused by a variety of proinflammatory factors induced by many causes, which is mainly characterized by noncardiogenic pulmonary edema.The main pathophysiological feature is the destruction of the integrity of the alveolar capillary membrane, and the loss of the alveolar epithelial-endothelial barrier function.In the PARDS′s clinical practice, the mainstay of the treatment is supportive.Although there is still no clear definition and general consensus or guidelines, appropriate liquid therapy is an important part of non-ventilatory treatment measures.Proper fluid management strategy is helpful to improve pulmonary edema, maintain normal circulatory perfusion, prevent functional failure of important organs and improve the prognosis of patients.According to volume status, implementing the goal-oriented and phased differentiated fluid management strategy is significant for the therapy of PARDS patients.However, the effects of fluid strategy management according to PARDS phenotypes remain to be evaluated.
