Objective To investigate two enteral nutrition injection methods on prognosis of patients with acute cerebral infarction (ACI) induced pseudobulbar palsy patients. Methods A total of 86 patients of ACI accompanied with dysphagia were randomly divided into the feeding pump group (n=43) and the traditional nasal feeding group (n=43). Nutritional support for both groups lasted at least more than 14 d through the feeding tube. In the first and fourteenth day data of both groups concerned with body mass index (BMI), triceps skin fold (TSF), upper arm muscle circumference of triceps (MAMC), heamoglobin (Hb), serum prealbumin (Alb), alanine transaminase(ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), creatinine (Cr), incidence of complications, neuro-function score NIHSS and the swallowing function evaluation were collected and analyzed. Results Nutritional index Hb and Alb was (132.6±10.1) g/L and (38.2±1.4) g/L in the group of the feeding pump group, and significantly higher than (122.2±13.2) g/L and (36.3±1.5) g/L in the traditional nasal feeding group in the fourteenth day, the difference was significant (t=12.86, 12.37, P<0.05). The NHISS score was 5.2±1.0 in the feeding pump group, significantly lower than 8.9±1.1 of the traditional nasal feeding group, the difference was significant (t=-26.37, P < 0.05). The improved rate of swallowing function was 81.4% (35/43) in the feeding pump group, significantly higher than 60.5%(26/43) of the traditional nasal feeding group, the difference was significant (χ2=4.568, P < 0.05). Conclusions The use of enteral feeding pump at early stage for ACI patients with pseudobulbar palsy can improve the nutritional status, acute neurological function, swallowing function and lower the incidence of complications which is beneficial for early recovery and short-term prognosis.
