The authors analyzed a group of 236 diabetic patients in the municipality of Novi Sad who asked for the help of the Emergency medical service of the Health Center "Novi Sad". A special emergency team which manages vitally endangered patients acted on their requests. After anamnestic data were gathered and physical examination done, electrocardiographic monitoring was performed. Glycemia was determined from semiquantitative analysis of the capillary blood, while glycosuria and acetonuria from urine. In regard to these patients the gathered results point to predominant presence of chronic, degenerative complications, especially of the cardiovascular apparatus. However, this was the case due to the fact that these were elderly persons (62.78 +/- 12.21 years of age) suffering from diabetes mellitus for about 8 years, which is sufficient for development of chronic, degenerative complications of diabetes. Although the studied group was metabolically unregulated (glycemia: 18.13 +/- 5.43 mmol/l, glycosuria positive in 4.54%, acetonuria in 2.20% of patients) there were no elements for diagnosis of some acute metabolic complications. The decrease of acute metabolic complications may be connected to better organization of the antidiabetic service in the municipality of Novi Sad. It is especially important to point out the occurrence of serious hypoglycemias caused by oral hypoglycemics (64.28%) which require, according to contemporary approach, a long-term hospital treatment.
