Background. Hyperglycemia is common and difficult to control in perioperative patients with type 2 diabetes mellitus (T2DM), which impacts their prognosis after operation. Our study investigated the short-term effect of continuous subcutaneous insulin infusion (CSII) and multiple daily injection (MDI) in perioperative T2DM patients using the data envelopment analysis (DEA). Methods. T2DM patients () who underwent surgeries in Guangdong Provincial Hospital of Traditional Chinese Medicine (2009.01-2017.12) were included. Insulin was provided to each patient during the study and separated into a CSII group () and an MDI group (). DEA was performed to compare the therapeutic indexes and investigate the short-term effect of the CSII group and MDI group. Results. Scale efficiencies of the CSII group with CCR model and BCC model were better than that of the MDI group. Regarding slack variables, with higher surgical levels, the CSII group was closer to the ideal state than the MDI group, which indicated in improving the average fasting blood glucose (AFBG), antibiotic use days (AUD), preoperative blood glucose control time (PBGCT), first postoperative day fasting blood glucose (FPDFBG), and postoperative hospitalization days (PHD). Conclusion. CSII could effectively control blood glucose levels and shorten perioperative hospitalizing time for T2DM patients, indicating that CSII was beneficial in perioperative period and should be promoted clinically.

持续皮下胰岛素输注和每日多次注射对围手术期 2 型糖尿病患者的短期效果

背景。高血糖在2型糖尿病（T2DM）围手术期患者中常见且难以控制，影响术后预后。我们的研究使用数据包络分析 (DEA) 调查了围手术期 T2DM 患者连续皮下胰岛素输注 (CSII) 和每日多次注射 (MDI) 的短期效果。方法。T2DM 患者（）纳入广东省中医院（2009.01-2017.12）接受手术的患者。研究期间向每位患者提供胰岛素，并分为 CSII 组（）和 MDI 基团（）。采用DEA比较CSII组与MDI组的治疗指标并考察近期疗效。结果。CCR模型和BCC模型CSII组的量表效率均优于MDI组。松弛变量方面，随着手术水平的提高，CSII组比MDI组更接近理想状态，这表明在改善平均空腹血糖（AFBG）、抗生素使用天数（AUD）、术前血糖控制时间（PBGCT）方面）、术后第一天空腹血糖（FPDFBG）和术后住院天数（PHD）。结论。CSII能够有效控制T2DM患者的血糖水平，缩短围手术期住院时间，表明CSII在围手术期是有益的，值得临床推广。
