[The effect of intravenous alimentation on protein synthesis after major operation]

The whole body protein was found to decline by 16.4% in patients after radical gastrectomy without IVN support, and the levels of visceral proteins, such as serum albumin, C-reactant and fibronectin, also obviously decreased. If IVN support was given after operation, the whole body protein synthesis was 57.7% higher than that in the controlled group. The blood levels of visceral proteins were also elevated, with a significant difference in the fibronectin concentration in IVN group as compared with either preoperative or controlled value.
