Abstract
The present study is a prospective cross sectional study aimed to assess whether venous blood lactate on hospital presentation is predictive of need for interventions and short term outcomes (eg PRBC transfusion, ICU admission ) in patients with acute GIB who presented to ED of Assuit University hospital between September 2019 and June 2022. The study included 300 patients with acute GIB. Out of those patients; 200 patients had elevated blood lactate and 100 patients had normal blood lactate.
It was found that mean age of patients with elevated lactate was significantly higher in comparison to those with normal lactate. There were no significant differences between both groups as regard risk factors for bleeding (use of anti-coagulants, aspirin), use of NSAIDs was higher among patients with normal lactate while history of prior UGIB was higher among patients with elevated lactate. The most frequent presentations among the studied patients were hematemesis and melena.
Both groups had insignificant differences as regard laboratory data, endoscopic findings and interventions.
Patients with elevated lactate had prolonged hospital stay, higher frequency of blood transfusion, ICU admission and mortality in comparison to those with normal blood lactate.
Based on the current study, predictors of mortality among patients with UGIB were old age , LC, elevated lactate and variceal bleeding.
So we could say that elevated blood lactate can be predictive for interventions and short term outcomes in patients with acute GIB ,however, further and similar studies with multi-center settings would be more reliable and accurate.
