Comparative analysis of the methods of anesthetic maintenance in patients with diabetes with the syndrome of diabetic foot requiring operative intervention

Abstract

Introduction: In the present article we draw a comparison between such types of regional anesthesia (RA) as unilateral spinal anesthesia (USA), traditional spinal anesthesia (SA) and block anesthesia of peripheral nerve trunk (block anesthesia of sciatic nerve (BASN) on the side of operative intervention) during surgical treatment of patients with the syndrome of diabetic foot. The aim of the article is to compare effectiveness, reliability and safety of such methods of RA as unilateral and traditional spinal anesthesia, as well as block anesthesia of sciatic nerve on the side of operative intervention. Materials and methods: 96 patients with the syndrome of diabetic foot, who received treatment in the department of purulent surgery, were examined. All patients underwent operative interventions of varying degrees of complexity depending on the nature and seriousness of damage degree of extremities, in terms of RA types under investigation. Effectiveness of regional block anesthesia, the time when anesthesia takes effect, duration and deepness were evaluated. Results: It should be noted that USA, as a variant of pain management during operations of foot, provides the most adequate level of surgical pain management in comparison with the other types of anesthesia. During block anesthesia of sciatic nerve more than half of patients are not provided with 100% surgical analgesia, which can lead to additional medicamentous analgosedation. According to the results obtained, pain sensitivity in patients after BASN is reliably higher than in patients after USA and SA in all stages of the study. Conclusions: RA is the main method of choice during operations on foot in comparison with the methods of general anesthesia. Unilateral spinal anesthesia is carried out with the use of smaller amount of anesthetic than traditional spinal anesthesia and block anesthesia of peripheral nerve trunk, which significantly reduces sympathectomy area and leads to the stable hemodynamic during the peri-operative period.
