RESUMO
Severe acute pancreatitis (SAP) is a common abdominal disorder contributing to high mortality and open laparotomy rates. The role of exogenous infused albumin in fluid resuscitation or continuous therapy has always been an unanswered question. In early stage after onset, SAP patients with higher serum albumin or prealbumin show a better prognosis. In this study, we tried to disclose the linkage between albumin/prealbumin and SAP prognosis and establish a new goal-directed therapy involving albumin and prealbumin. Pearson's chi-squared test and the Mann-Whitney U test were used to compare the descriptive data between surviving and non-surviving patients. Three days, 4-7 days, 8-14 days and 15-28 days after SAP onset were defined as stages 1-4. The average concentrations of albumin and prealbumin were calculated, and receiver operating characteristic (ROC) curves were drawn to screen out the best cutoff values associated with poor prognostic outcomes, including laparotomy and failure to survive. Kaplan-Meier survival curves and log-rank tests were used to validate the effect of the cut-off values. A total of 199 admitted patients were enrolled in this study. According to the analysis of the ROC curve, the serum albumin value should be raised to 35, 37, 40 and 42 g/L in the 1-4 stage after onset. Serum prealbumin values should be raised to 108, 180, and 181 g/L in stages 2-4 after onset. The validity of the above data was confirmed by Kaplan-Meier survival curves. Serum albumin and prealbumin levels in the early stage of SAP are significantly relevant to prognosis. Albumin should be infused from the fluid resuscitation stage to continuous therapy in order to reach the targets mentioned above. The increase in prealbumin depends on the early initiation of enteral nutrition and this also helps to ameliorate the prognosis.
