The patients were provided with 1) basic treatment including intracranial pressure reduction, anti-infection therapy, blood pressure and blood glucose control, and 2) comprehensive rehabilitation therapy including respiratory tract management, care for tracheotomy tube, comprehensive training for hemiplegic limbs, swallowing function training, pulmonary function training, and acupuncture.

For the observation group, the nasogastric tube was removed, and Intermittent oro-esophageal tube feeding was initiated for nutrition support within 4 hours after completing the admission assessment, following the standard Intermittent oro-esophageal tube feeding procedure.

The patients were provided with 1) basic treatment including intracranial pressure reduction, anti-infection therapy, blood pressure and blood glucose control, and 2) comprehensive rehabilitation therapy including respiratory tract management, care for tracheotomy tube, comprehensive training for hemiplegic limbs, swallowing function training, pulmonary function training, and acupuncture.

Patients in the control group were provided with nutrition support by the indwelling nasogastric tube. The entire feeding process strictly followed the standardized procedure for nasogastric feeding.

The observation group was given enteral nutritional support with Intermittent Oro-esophageal Tube Feeding according to the following procedure: Before each feeding, inside and outside of the tube was cleaned with water. During feeding, the patient should maintain a semi-reclining or sitting position with mouth opened, and the tube was inserted slowly and smoothly into the upper part of the esophagus by medical staffs while the appropriate depth of intubation was checked with the calibration markings on the tube wall. The distance from the incisors to the head part of the tube should be between 22-25 cm. However, the specific depth should be evaluated based on patients' feedback and adjusted accordingly. After insertion, the tail part of the tube should be put into a container full of water and the absence of continuous bubbles indicated a successful intubation. Then, the feeding was to be conducted three times per day with 50 ml per minute and 400-600ml for each feeding.

The Number of cases of successful extubation for both groups was recorded and compared. The parameters or criteria for extubation were: 1) stable clinical condition and a respiratory rate of 12-22 breaths per minute. 2) strong coughing ability and minimal airway secretions. 3) after completing a trial of tracheostomy tube capping, patients showed no fever, dyspnea, or asthma within 72 hours. Additionally, their blood oxygen saturation remained above 95% and normal oxygen partial pressure was observed

Weight and height will be combined to report Body mass index in kg/m^2

Serum albumin was recorded via blood routine test.(Alb, g/L)
