Abstract

Introduction. According to the International Diabetes Federation (Diabetes Federation), the number of patients with diabetes mellitus (DM) is progressively increasing. About 7 million new cases of diabetes are diagnosed every year and annually 3.8 million people die from diabetes related causes. Diabetes is an independent risk factor for cardiovascular diseases and it is also the leading cause of death in patients with type 2 diabetes. Prevention and treatment of late complications of diabetes, including diabetic foot syndrome (DFS), is one of the most important problems of endocrinology. Purpose of the study. Analysis of the main methods of anesthesia in order to choose the one that will have the minimal impact on the cardiovascular, endocrine, respiratory and other body systems. Anesthesiologic support in this complex category of patients should be directed not only to relief of severe pain syndrome during the perioperative period, but also to improvement in trophism of tissues, as the pain supports spasm and microcirculation disorders. The choice of safe anesthetic method for patients in this group will reduce the risk of developing certain complications. Material and methods. Authors performed search and study of information regarding the topic: «Anesthesiologic methods for patients with DFS and critical ischemia of the lower limbs» in the main medical and biological databases. Each method was examined, and the most optimal alternatives were identified. Results. Epidural and conductive anesthesia seem like the most rational alternatives as these two methods not only guarantee a high-quality intraoperative anesthesia, but they also can be used for a long-term pain relief. These types of anesthesia have minimal effect on the cardiovascular system. Also, epidural and conductive anesthesia have an influence on the pathogenetic mechanisms of the disease. Conclusions. All patients with DFS and critical ischemia of the lower extremities of course can be placed under conduction anesthesia. Considering trophic effects, it is preferable to use prolonged blockade of peripheral nerves, by catheterization. Because of the mandatory use of antiaggregant therapy, epidural anesthesia is not recommended for in these patients.
