Abstract

Background
Admission in intensive care unit is frequent for patient presenting non-variceal upper gastrointestinal bleeding (NVUGIB). To determine prognosis of those NVUGIB, prognostic scores should be used, but they are not always available at admission. The shock index (SI) is calculated from systolic blood pressure (SBP) and heart rate (HR) could more easily assess morbidity and mortality, especially, when biological and endoscopic data are hardly available like for Malagasy patients. The aim of this study is to analyze the shock index in non-variceal upper gastrointestinal bleeding in intensive care.
Method
In a six-year retrospective study in surgical intensive care unit of a Malagasy university hospital (CHUA-JRA), patients admitted for NVUGIB, hemodynamic parameters were studied. The correlations between the SI and the transfusion, the recurrence and/or the surgery, and the mortality were evaluated and the receiver operating curves (ROC) curves of the hemodynamic parameters were analyzed.
