- Abstract: OBJECTIVE: To analyze the factors influencing postpyloric placement of spiral nasoenteral feeding tube(NET) in neurocritical care patients and establish a visualized prediction model. METHODS: Patients in Neurological Intensive Care Unit(NICU)who undertook postpyloric placement of NET after receiving prokinetics from Apr 2012 to Mar 2018 were included for retrospective analysis. The patients were divided into the success and failure group base on whether the tube tip entered into duodenum(or beyond)or not confirmed by bedside X-ray 24 hours later. The baseline data, APACHE Ⅱ score(acute physiology and chronic health evaluation Ⅱ), AGI grade(acute gastrointestinal injury), therapeutic measures and agents administered were recorded. Univariate and multivariate Logistic regression analysis was used to identify the potential factors affecting the postpyloric placement of NET. Based on those factors, a predicting model was established and visualized into an easy-to-use nomogram. RESULTS: A total of 241 patients including146 male and 95 female were enrolled for the study, with an median age of 58 years, median APACHEⅡscore of 20, median AGI of Ⅰ.The placement succeeded in 119(49.4%) of 241 patients. Logistic regression analysis demonstrated that APACHE Ⅱ score, sedatives and analgesics, vasopressors and AGI grade were among the influencing factors. A prediction model with a ROC-AUC of 0.8002 were established and visualized into a nomogram. CONCLUSION: APACHE Ⅱ score, sedatives and analgesics, vasopressors and AGI grade are the factors influencing success of postpyloric NET placement in neurocritical care patients, which incorporate a predicting model that can be visualized into a nomogram. The nomogram provided intensivists an easy-to-use decision support tool in NET placements.
