Abstract
Objective To investigate the correlation of postoperative cognitive dysfunction (POCD)and the preoperative he-moglobin (HbA1c)in elderly patients with type 2 diabetes mellitus (T2DM).Methods 82 patients with T2DM who were underwent non-cardiac surgery were included in this study,group A had 37 patients with POCD after surgery,group B had 45 patients with non POCD,the patients in two groups used the same anesthesia method,compared the general data and pre-operative HbA1c,fasting blood glucose levels of two groups,compared the incidence of POCD in patients with HbA1c in dif-ferent levels.Results There was no significant difference in gender composition,age,body mass index,preoperative MMSE score,hypertension rate,operation time and bleeding volume in operation,and there was no significant difference in fasting blood glucose of patients in two groups.Fasting blood-glucose (FBG)of two groups were 7.1±2.6 and 6.7±1.8 mmol/L (t=0.821,P=0.424),it was no significant difference;HbA1c of two groups were (7.2±1.3)% and (6.3±1.0)%,the group A was higher than the group B (t=3.543,P=0.001),there was significant difference.The incidence rate of POCD of the group AH was 58.1%(25/43),while the group AL was 30.8% (12/39),the group AH was higher the group AL(χ2=5.131,P=0.024),there was significant difference.Conclusion Preoperative determination of HbA1c in elderly patients with T2DM after surgery has forecast values for the occurrence of POCD,to control HbA1c in the low level can reduce the occurrence of POCD in elderly patients with T2DM.关键词
