Objective:To screen the predictive factors of gastric tube placement in patients with acute cerebral hemorrhage, and to construct a predictive model of gastric tube placement in patients with acute cerebral hemorrhage and analyze its diagnostic efficacy.Methods:A total of 1 425 patients with acute cerebral ischemia admitted to PMUCH from May 2007 to May 2019 were selected as subjects. The patients were divided into the gastric tube group (observation group, n=135) and the unimplanted group (control group, n=1 290) according to whether the patient was placed in the stomach tube after admission. Logistic regression was used to analyze the predictive factors affecting the placement of gastric tube in patients with acute cerebral hemorrhage, and to construct a predictive model for the placement of gastric tube in patients with acute cerebral hemorrhage. The receiver operating characteristic curve (ROC) was used to analyze the occlusive hydrocephalus + severity of disease + standardized swallowing assessment (SSA) grade + swallowing test (model A) to predict the efficacy of placement of gastric tube in patients with acute cerebral hemorrhage. Results:There were significant differences between the two groups in terms of education, residence, intraventricular hemorrhage, occlusive hydrocephalus, dementia, heart failure, psychological reaction, SSA classification, disease severity, and swallowing test ( χ 2 value was 10.182-99.194, P<0.05). Logistic regression analysis showed that the occlusive hydrocephalus, severity of disease, SSA grade, and swallowing test were closely related to the placement of gastric tube in patients with acute cerebral hemorrhage. The area under the curve (AUC), sensitivity, and specificity of model A in predicts that placement of gastric tube in patients with acute cerebral hemorrhage were 0.874, 77.78%, and 89.30%, respectively. Results:The occlusive hydrocephalus, severity of disease, SSA grade, and swallowing test were closely related to the placement of gastric tube in patients with acute cerebral hemorrhage. The model constructed by the four models can predict the risk of patients with gastric tube and has higher efficacy.
