Purpose: To observe the effect of dynamic nutrition support on postoperative energy metabolism, immune function and stress response in patients with oral and maxillofacial tumors.
Methods: Fifty-six patients with oral and maxillofacial tumor surgery were randomly divided into experimental group and control group (28 in each group). Patients in the experimental group received dynamic enteral and parenteral nutrition support according to the stress period after surgery, ω-3 fish oil fat milk injection and glutamine were added in the nutrition support program. Patients in the control group were given routine postoperative enteral and parenteral camp support. Energy metabolism, immune function and stress indexes were detected 1 day before surgery, 2 days after surgery and 7 days after surgery, respectively. SPSS 19.0 software package was used to analyze the data.
Results: Energy metabolism indexes in the experimental group were higher than the control group on day 2 after PA surgery and day 7 after ALB and PA surgery, while energy metabolism indexes in the experimental group were lower than the control group on day 2 and day 7 after FPG and TG surgery with significant difference(P<0.05). The levels of IgA, IgG, IgM, CD3+, CD4+ and CD4+/CD8+ in the experimental group were higher than those in the control group 7 days after surgery, with significant differences (P<0.05). The levels of CRP, TNF- and IL-6 in the experimental group were lower than those in the control group 7 days after surgery, and the difference was significant(P<0.05). There was no significant difference in postoperative complications between the two groups.
Conclusions: Dynamic nutrition support can improve postoperative energy metabolism of patients with oral and maxillofacial tumors, improve immune function, and alleviate stress response.
