摘 要:目的探讨骨折合并2型糖尿病(type 2diabetes mellitus,T2DM)患者围手术期胰岛素泵持续皮下胰岛素输注的治疗效果,分析影响疗效和胰岛素用量的相关因素。方法 78例骨折合并T2DM患者围手术期行胰岛素泵强化治疗,观察总体胰岛素泵的应用情况;根据年龄分为老年组(≥60岁)38例和非老年组(<60岁)40例,根据体质量指数(body mass index,BMI)分为肥胖组(≥25kg/m2)40例和非肥胖组(<25kg/m2)38例,根据糖尿病病程分为长病程组(≥10a)33例和短病程组(<10a)45例,根据不同基础血糖水平分为高糖化血红蛋白(glycosylated hemoglobin A1c,HbA_1c)组(≥8%)35例和低HbA_1c组(<8%)43例。比较各亚组患者胰岛素泵应用效果,以及低血糖等并发症发生情况;采用多元线性回归分析影响血糖达标时间和达标时胰岛素用量的相关因素。结果骨折合并T2DM患者术前胰岛素泵强化治疗时间(2.5±1.7)d,血糖达标时胰岛素用量(0.67±0.16)u/(kg·d);肥胖组血糖达标时间[(2.90±1.50)d]和达标时胰岛素用量[(0.74±0.12)u/(kg·d)]多于非肥胖组[(2.10±1.20)d、(0.64±0.14)u/(kg·d)](P<0.05),高HbA_1c组入院时合并酮症比率(48.6%)、血糖达标时间[(2.90±1.60)d]和达标时胰岛素用量[(0.76±0.12)u/(kg·d)]多于低HbA_1c组[20.9%、(2.20±1.10)d、(0.63±0.13)u/(kg·d)](P<0.05);治疗中老年组低血糖发生率(23.7%)高于非老年组(7.5%)(P<0.05),高HbA_1c组术后酮症发生率(73.3%)高于低HbA_1c组(45.0%)(P<0.05);血糖达标时间与BMI(β=0.241,P=0.028)、入院时合并酮症(β=0.233,P=0.040)和HbA_1c(β=0.231,P=0.046)呈独立相关,达标时胰岛素用量与BMI(β=0.279,P=0.007)和HbA_1c(β=0.400,P<0.001)呈独立相关。结论胰岛素泵持续皮下胰岛素输注是控制骨折合并T2DM患者围手术期血糖的理想方案,不同人群应用效果存在差异,起始胰岛素剂量应根据患者BMI和HbA_1c水平确定。Objective To investigate the therapeutic effect of perioperative application of continuous subcutaneous insulin infusion (CSID in patients with bone fractures and type 2 diabetes mellitus (T2DM) and to analyze the influencing factors for the therapeutic effect and insulin dosage. Methods Seventy-eight patients with bone fractures and T2DM received perioperative CSII, and were divided into elderly group (≥60 years old, n=38) and non-elderly group (〈60 years old, n:40) according to the age, into obesity group (body mass index (BMI) ≥25 kg/m2 , n= 40) and non-obesity group (BMI 〈25 kg/m2 , n:38) according to the BMI, into long diabetes course group (≥10 years, n=33) and short diabetes course group (〈10 years, n=45) according to the diabetes course, and into high glycosylated hemoglobin A1c (HbA1c) group (≥8%, n=35) and low HbAlc group (〈8%, n=43) according to the baseline plasma glucose level. The effect of CSII and the complications as hypoglycemia were compared between each pair of subgroups. Multivariate linear regression analysis was applied to analyze the related factors of the time of achieving glycemia target and insulin dosage on achieving glycemia target. Results The time of achieving preoperative glycemia target was (2.5 ± 1.7) d with the insulin dosage of (0.67±0. 16) u/(kg·d) in all patients. The time of achieving glycemia target was longer and the insulin dosage was larger in obesity group ((2. 90±1. 50) d, (0. 74±0. 12) u/(kg· d)) than those in non-obesity group ((2.10±1.20) d, (0.64±0. 14) u/(kg·d)) (P〈0.05). The rate of ketosis at admission was higher, the time of achieving glycemia target was longer and the insulin dosage was larger in high HbA1 c group (48.6%, (2.90± 1.60) d, (0.76±0.12) u/(kg·d)) than those in low HbAlc group (20.9%, (2.20±1.10) d, (0.63±0.13) u/(kg· d)) (P〈0.05). The incidence of hypoglycemia was significantly hig
