AbstractDiabetic patients presenting for elective surgical procedures will place an increasing burden on anaesthetic services. The effects of surgical stress and anesthesia result in a a hypermetabolic stress response, referred to as “stress hyperglycemia”. The aim of the study is to compare stress response to general anaesthesia by measuring the rise in blood glucose levels in controlled diabetics posted for elective surgical procedures in comparision with non-diabetic patients .Study was conducted in Department of Anaesthesiology, Osmania Medical College/Hospital, Hyderabad during 2010- 2012 in Fifty ASA Grade I & Grade II patients. Institutional Ethics Committee has approved the study, written and informe consent was obtained from the patients. The study population were in the age group of 35-55 years, of either sex divided into two groups scheduled for elective surgical procedures of 2 hours of duration (viz., laporatomy, thyroidectomy). A Opiod (Fentanyl) and Propofol based balanced general anaesthesia technique adequately attenuates Hyperglycemic Stress Response in Controlled Diabetics.
