The patients were categorized into a survival group (<jats:italic>n<\/jats:italic>\u2009=\u200914) and a non-survival group (<jats:italic>n<\/jats:italic>\u2009=\u200918) based on their clinical outcomes. Baseline characteristics, including age, sex, and body weight and so on were collected for both groups. Multivariate logistic regression analysis was used to identify risk factors influencing patient prognosis. The prognostic value of relevant indicators was assessed using receiver operating characteristic curve analysis, while Pearson's correlation analysis was conducted to assess the relationships between specific indicators.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Lactate clearance was significantly lower in the non-survival group compared to the survival group, while fluid balance and APACHE II scores were notably higher in the non-survival group (<jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05). Based on the predictive model, the APACHE II score demonstrated the highest specificity for prognosis at 97.4%, whereas the combined indices exhibited the highest sensitivity at 95.5%. Additionally, lactate clearance revealed a negative correlation with both fluid balance and APACHE II scores (<jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This pilot study demonstrated that lactate clearance, fluid balance, and APACHE II score are valuable prognostic indicators for patients; however, the predictive accuracy of individual indicators is limited. The combined assessment of these indices provides a more robust and reliable predictive performance.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2025.1557909","type":"journal-article","created":{"date-parts":[[2025,5,7]],"date-time":"2025-05-07T05:13:43Z","timestamp":1746594823000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Prognostic
