To compare efficacy and safety of a new modified post-pyloric feeding tube bedside catheterization with Corpak 10-10-10 protocol and electromagnetic guided catheterization for treatment of patients with dysphagia and at high-risk of aspiration pneumonia. We conducted a single-center, single-blinded, and randomized controlled clinical trial. A total of 63 patients were treated with the non-gravity type CORFLO gastrointestinal feeding tube between 2017.1 and 2019.1 using different procedures: in the M group, patients underwent modified post-pyloric feeding tube bedside placement; in C group, patients underwent conventional Corpak protocol; in EM group, patients received standard electromagnetic guided tube placement.

Inclusion Criteria:

• All patients had dysphagia that could not be alleviated within 48 hours
• High-risk status with aspiration pneumonia, including consciousness disorder caused by various diseases, severe dementia, bed rest, gastroesophageal reflux, hiccup, gastric retention, achalasia of pyloric.
• Can't receive nasogastric tube feeding.

Exclusion Criteria:

• The previous history of upper abdominal surgery.
• Gastroduodenal ulcer and esophagogastric varices;
• Severe sinusitis and nasal bone fracture;
• Patients with recent gastrointestinal bleeding, intestinal obstruction, ischemic bowel disease, and epistaxis;
• Patients with electromagnetically-guided catheterization should additionally exclude implantable cardiac defibrillator, implantable cardiac pacemaker or diaphragm pacemaker.

Sixty-three patients with dysphagia from Department of Rehabilitation, the Second Affiliated Hospital of Zhejiang University School on January 1, 2017 to January 1, 2019. All the patients included in this study were in accordance with the guide of diagnosis and treatment of swallowing disorders of diagnostic criteria.
