Comparative Analysis of the Predictive Utility of Gastric Mucosal PH and Lactate in Septic Shock

< 0.001), indicating that combined assessment markedly improves prognostic accuracy in septic shock.ConclusionBoth gastric mucosal pH and blood lactate levels were associated with in-hospital mortality in patients with septic shock. While lactate did not achieve statistical significance as an independent predictor in the current model, PHi demonstrated an independent connection with prognosis in the multivariable analysis. These results imply that gastric mucosal pH may provide a potential regional perfusion viewpoint for evaluating the state, in contrast to lactate, which represents systemic metabolic status. Significantly, predictive accuracy increased when both markers were evaluated together, suggesting that systemic and regional indicators can be complementing in risk assessment.
