To investigate the effects of different target blood glucose control on postoperative complications during fasting after abdominal surgery by Meta-analysis.

From January 1990 to May 2016 the computer retrieval of related Chinese and foreign literature into surgery during the fasting blood glucose control in different range of patients, were randomly divided into control group and intervention group, from two independent data extraction and document evaluation. Meta-analysis using RevMan5.3 software.

A total of 6 articles were included. Meta-analysis results showed that after abdominal surgery during the fasting of different target blood glucose control on the incidence of hypoglycemia, the incidence of postoperative complications of surgical incision infection after operation, the differences were statistically significant (P<0.05), However, there was no significant difference in postoperative mortality rate (P>0.05).

After abdominal surgery in patients with intensive glycemic control during the fasting, value at the lower range (4.4-6.1mmol/L) can effectively reduce the incision infection and the incidence of postoperative complications, is conducive to the rehabilitation of patients, but increase the risk of hypoglycemia, and it has little effect on the mortality of patients during hospitalization. The control group included blood glucose range is too large or lack of continuity and included in the study Chinese literature is too small, leads to a limitation of the research, the analysis results still need more clinical nursing practice and a large number of high quality documents to support.
