title: [Use of base deficit as a prognosis factor for acute pancreatitis].
abstract: BACKGROUND
  Acute pancreatitis (AP) severe is accompanied by important morbidity and mortality. Tissular hypoperfusion has been suggested as a severity determinant. Base deficit (BD) demonstrated to be a good indicator of hypo-perfusion. We established predictive value in AP.
  
  
  METHODS
  A retrospective, longitudinal, descriptive, and observational study was carried out. We included hospitalized patients from January 1996 to December 2000 with confirmed diagnosis of AP for laboratory, tomography and/or surgery; and with determination of BD on admission. Patients were divided into groups with or without BD and were compared with certain severity and mortality.
  
  
  RESULTS
  We study 104 patients, 40(38%) without BD and 64 (62%) with BD. The mortality belonged to 22 patients (21.2%), all of the group with BD. The BD had a sensibility of 71.4% to predict severity and of 100% for the motility
  
  
  CONCLUSIONS
  BD allows predicting severity and mortality in AP. These points out the role that carried out tissular hip perfusion; in addition, it can serve as guide for appropriate treatment.
