冠状动脉旁路移植术后血糖变化临床分析

目的：分析冠状动脉旁路移植术（CABG）后患者高血糖的发生率及血糖的变化规律。方法：回顾性分析我院2005年1月～2009年12月行CABG的冠心病患者138例的糖尿病史、术前术后血糖水平、后高血糖和血糖峰值的出现时间等资料。按术前有无糖尿病分为糖尿病组和非糖尿病组,比较析两组的差异。结果：138例患者中有101例发生术后高血糖,发生率为73.2%,非糖尿病组发生率为69.7%;糖尿病组发生率为77.4%,2组术后高血糖发生率未见统计学差异（x2=1.027,P=0.3109）。术前血糖水平与术后高血糖发生率呈正相关,99.0%的患者出现在入住重症强医疗病房（ICU）24h以内,术后血糖峰值的出现时间入住ICU16h,且非糖尿病组出现时间较糖尿病组早。结论：CABG后高血糖的发生率较高,且绝大多数出现在术后24 h以内,术后高血糖发生率与术前血糖水平呈正相关。

Analysis of Post-Operative Hyperglycemia after Coronary Artery Bypass Grafting

Objective：To analyze the incidence of post-operative hyperglycemia and the changing feature of blood glucose after coronary artery bypass grafting（CABG） surgery in department of intensive care unit（ICU） patients.Methods：The clinical data of 138 patients,who were undergone CABG surgery in our hospital from January 2005 to December 2009,were retrospectively analysed.The patients were divided into diabetic group and nondiabetic group.Results：The incidence of post-operative hyperglycemia was 73.2%,which were 69.7% and 77.4% in the non-diabetic group and diabetic group,but there were no significant difference between 2 groups（x2=1.027,P=0.3109）.And there were positive relationship between pre-operative BG level and incidence of post-operative hyper-glycemia.About 99.0% occurred in the first 24 hours admitted to ICU.The peak BG occurred in the first 16 hour admitted to ICU,which was significantly earlier in the non-diabetic group compared with the diabetic group.Conclusion：There is a higher incidence of post-op-erative hyperglycemia after CABG,most of them occur within 24 hours after operation.And the incidence of post-operative hyper-glycemia is related to relate to pre-operative BG level.
