Objective:

To compare the clinical effects of two enteral nutritional emulsions, TP-HE and TPF, in elderly patients with severe pneumonia.

Methods:

This was a randomized study with contemporaneous controls.A total of 56 elderly patients over 65 years old who met the diagnostic criteria for severe pneumonia and were receiving insulin were enrolled.They were randomly divided into the observation group(n=28, enteral TPF-HE at a uniform rate through a nasogastric tube)and the control group(n=28 cases, enteral TPF at a uniform rate through a nasogastric tube). The total daily energy supply was calculates based on the ideal weights of patients.Prealbumin(PA), serum albumin(ALB), body mass index(BMI)and hemoglobin(Hb)were continuously measured at 1, 2, 3, 4, 5, 6 and 7 days after treatment.The effects of the enteral nutritional emulsions in elderly patients with severe pneumonia were analyzed by using repeated measures analysis of variance in a general linear model.

Results:

There was no significant difference in PA(244.5±55.1)mg/L vs.(237.8±40.4)mg/L, ALB(37.6±5.6)mg/L vs.(38.3±5.5)mg/L, BMI(21.9±0.2)kg/m 2vs.(22.4±0.2)kg/m 2)or Hb(104.4±26.8)mg/L vs.(103.6±25.6)mg/L between the TP-HE group and the TPF group before admission( P>0.05). The energy received from the enteral nutritional emulsions was not significantly different between the TP-HE group and the TPF group(79.8±4.8)kcal/d vs.(79.3±6.6)kcal/d( P>0.05). PA and serum ALB levels had significant differences between the TP-HE group and the TPF group at 1, 2, 3, 4, 5, 6 and 7 days after treatment( P<0.01 or 0.05). Increases in PA and serum ALB levels varied at certain time points between the TP-HE group and the TPF group.Hb levels had no significant difference at 1 and 2 days( P>0.05), but were significantly different at other time points between the two groups( P<0.01). There was no significant difference in BMI between the two groups( F=1.709, P>0.05).

Conclusions:

Both of the enteral nutrition emulsions can improve PA, ALB and Hb levels, with TP-HE offering more significant effects on PA, ALB and Hb levels.There is no difference in BMI at any time point whether patients receive TP-HE or TPF.
