Abstract:

Aim: Micro and macrovascular complications due to long-term hyperglycemia are associated with increased mortality and morbidity. Erythrocytes exposed to hyperglycemia for a long time may cause morphological changes in erythrocytes such as decreased deformability and development of aggregation. As a result, complications such as shortening life span of erythrocytes, impairment of oxygen carrying capacity, tissue hypoxia may occur. In our study, we would like to investigate the effects of Sevoflurane and Desflurane on erythrocyte deformability during transient hyperglycemia. Materials and Methods: In this study, 30 male Wistar albino rats were used. The animals were randomly divided into five groups, each contained 6 rats: Diabetic control (group DC), diabetic hyperglycemia group (group DH), diabetic hyperglycemia group with desflurane (group DH-D), and diabetic hyperglycemia group with sevoflurane (group DH-S) groups. Another 6 rats without diabetes were assigned as control group (group C). Streptozotocin-induced diabetic rats were kept 6 weeks, then transient hyperglycemia was created, and the administration of sevoflurane and desflurane were performed. After 24 hours blood samples were obtained and deformability measurements were performed in erythrocyte suspensions containing Htc 5% in a PBS buffer. Results: Diabetes mellitus was found to increase relative resistance in the control group (p <0.0001). Acute hyperglycemia increased relative resistance in diabetes control, relatively. Group DH, Group DH-D and Group DH-S deformability index were significantly different when compared to Group DC (p=0.007, p=0.025, p=0.016, respectively). It was found that administration of desflurane or sevoflurane did not alter erythrocyte deformability during acute hyperglycemia (p = 0.591, p = 0.739). Conclusion: As a consequence, we think that we can safely use inhalation anesthetics such as Desflurane and Sevoflurane during acute hyperglycemia attacks. But, it needs further investigation as both experimental and clinical
