Efficacy of continuous intravenous pumping of insulin for patients with diabetes complicated with perianal abscess and the effect on inflammatory cytokines.

Efficacy of insulin with different administrations for patients with diabetes complicated with perianal abscess and the effect on serum inflammatory cytokines were investigated. One hundred and sixty-seven patients with type 2 diabetes who underwent radical operation of perianal abscess in Jinhua Hospital of Zhejiang University from January 2014 to December 2016 were analyzed. Before and after the operation, 89 patients who received continuous intravenous pumping of insulin for blood glucose control were set as an observation group, and 78 patients who received intermittent subcutaneous injection of insulin as a control group. The operative efficacy, wound healing time and 1-week postoperative growth of the granulation tissue were scored and compared. Fasting blood glucose (FBG) and 2 h postprandial blood glucose (2hPBG) before and after treatment were recorded and compared. Fasting venous blood was extracted before and on the 3rd and 7th days after operation to detect and compare serum inflammatory cytokines including tumor necrosis factor (TNF-α) and interleukin-6 (IL-6). Patients in the observation group had significantly higher total effective rate of the operation than that in the control group (P<0.05), and significantly shorter wound healing time and significantly lower growth score of the granulation tissue (P<0.05). Before treatment, there was no significant difference between the two groups in FBG and 2hPBG (P>0.05). After treatment, FBG and 2hPBG were significantly lower than those before treatment (P<0.050), and FBG and 2hPBG after treatment in the observation group were significantly lower than those in the control group (P<0.05). In conclusion, insulin pumps for injection during the perioperative period of patients with diabetes complicated with perianal abscess can better control the patients' blood glucose, improve the operative efficacy and promote the patients' postoperative healing. Moreover, continuous intravenous pumping of insulin is significantly better than traditional intermittent subcutaneous injection of it in controlling inflammation, so it is worthy of application.
