Objective  To investigate the clinical efficacy of nutritional support with different proportion of fat on the prognosis of patients with severe community-acquired pneumonia (SCAP). Methods  Ninety SCAP patients with nutritional risk treated between January 2014 and July 2015 were randomized into high, normal, and low-proportion fat groups with 30 patients in each. The patients in different groups underwent nutritional support with different fat proportion besides the same medication. Data of albumin, pre-albumin and transferrin were collected and analyzed before treatment and 10 days after treatment. The mortality rates were compared between groups. Results  Albumin, pre-albumin and transferrin were similar in all groups before intervention (P>0.05); albumin, pre-albumin and transferrin increased significantly 10 days after treatment in each group (P<0.05). Patients in the normal-fat group acquired significantly more obvious improvements on each index (P<0.05). A shorter length of stay in hospital was observed in the normal-proportion fat group compared with the high and low-proportion fat groups, but there was no significant differences among groups (P>0.05). On the 10th day, the normal -proportion fat proportion group had a significantly higher cure rate and a significantly lower mortality rate than the other two groups (P<0.05). The improvement rate was similar in all groups (P>0.05). Conclusion  Supportive treatment with normal fat proportion has a promising value in the improvement of albumin, pre-albumin and transferrin for SCAP patients with a shorter length of stay in hospital, which is worthy of clinical promotion.
