Abstract

Background: Acute gastrointestinal bleeding (GI bleeding) can range from mild symptoms to life-threatening conditions that require emergency intervention. Therefore, it is important to first identify the high-risk and low-risk patients in the emergency department (ED). Aims: This study aimed to investigate the usefulness of a three-hourly interval for determining the lactate clearance, which is shorter than the time interval in previous studies, in order to predict the prognosis early in patients with GI bleeding. Methods: This retrospective study involved patients who visited for complaining of GI bleeding symptoms. Initial lactate levels were measured upon arrival at the ED and measured again 3 h later after performing initial resuscitation. And 3-h lactate clearance was calculated. Lactate and 3-h lactate clearance for predicting outcomes were evaluated by the area under the receiver operating characteristic (AUROC) curve. Results: A total of 104 patients were enrolled and 21 patients (20.2%) died in the hospital. Multivariate logistic regression showed that 3-h lactate clearance was a significant predictor of in-hospital mortality. The AUROC of 3-h lactate clearance for predicting in-hospital mortality was 0.756. The sensitivity and specificity were 66.67% and 75.90%. On combining lactate clearance, total bilirubin, and PTT, the AUROC was 0.899 for predicting in-hospital mortality. Conclusions: This study validated that lactate clearance at three-hourly intervals is useful for early prediction of mortality and prognosis in patients with GI bleeding. It is important to perform not only an initial lactate measurement, but also a follow-up lactate measurement after initial resuscitation to check the lactate clearance.
