[Early fluid resuscitation in severe acute pancreatitis]

Fluid resuscitation is the cornerstone in the early treatment of severe acute pancreatitis(SAP). The endpoints of fluid therapy should be closely monitored early in the disease course by different methods, such as clinical status, pressure indicators, volume indicators, the maintain of microcirculation and the tissue oxygenation. To avoid volume overload that may lead to complications such as pulmonary edema and abdominal hypertension, it is critical to adjust the ratio of crystalloid-colloid and the speed of the liquid timely according to the dynamically assessment of fluid responsiveness and tolerance, the perfusion of macrocirculation and microcirculation and the stage of the fluid resuscitation, so as to improve the efficacy and safety of early fluid resuscitation in the treatment of SAP.
