糖尿病患者的围手术期并发症及死亡率较非糖尿病患者约高5倍,作者对114例患者进行分析,归纳其可能原因为:(1)脂肪代谢紊乱导致心血管及神经方面病变;(2)糖代谢障碍导致机体粒细胞吞噬功能下降,出现顽固性感染;(3)手术应激状态内分泌改变,以致脂肪、蛋白分解,糖原异生,胶原蛋白合成减少,造成切口裂开或难愈。对糖尿病患者急诊手术血糖宜控制在8～17mmol/L。择期手术血糖宜控制在6.7～10mmol/L。 Perioperative complications and mortality in patients with diabetes than non-diabetic patients about 5 times higher, the 114 patients were analyzed, the possible causes are summarized as follows: (1) fat metabolism disorders lead to cardiovascular and neurological changes; (2) ) Glucose metabolism disorders lead to decreased phagocytic function of the body, stubborn infection; (3) surgical stress state endocrine changes, resulting in fat, protein breakdown, gluconeogenesis, reduced collagen synthesis, resulting incision split or difficult to cure . Diabetes patients with emergency surgery blood glucose should be controlled at 8 ~ 17mmol / L. Elective surgery blood glucose should be controlled at 6.7 ~ 10mmol / L.
