The Perioperative Management of Diabetic Patients: A Retrospective Study / 대한마취과학회지

ABSTRACT

BACKGROUND: Diabetic patients have more chance of requiring surgery than non-diabetic population. Glycemic and metabolic controls are key points in the perioperative diabetic management. A variety of methods have been proposed for the management of diabetics perioperatively, but their effectiveness is still controversial. This study was done to investigate whether diabetic patients are managed appropriately in perioperative period. METHODS: Among diabetic patients referred to anesthesiologic outpatient clinic from August 1997 to September 2002, 85 patients were randomly selected Diabetic duration, medication for diabetic control, concurrent illness and referral surgical department was recorded. In preoperative routine laboratory findings, HbA1c, fasting glucose and postprandial glucose were checked Perioperative glucose control protocols applied to patients were investigated RESULTS: Patients received 1.32 operation per person. Diabetic duration was 12.2 +/- 7.2 years, thirty nine patients had take oral hypoglycemic agent and thirty one patients had received insulin. Mean HbA1c was 8.0 +/- 1.6%, thirty four patients showed above 8.0%. Alberti's regimen was used in fifty five patients and insulin was omitted in fifty six patients. Two patients received insulin of half of usual dose in the morning. Alberti's regimen in major surgery and no insulin in minor surgery were preferred. The composition of Alberti's regimen and target blood glucose level varied. During operation, blood glucose was checked only in fourty four cases. Five of seven postoperative hypoglycemic patients were not checked glucose level during operation. Mortality rate was 7% and major cause of death was sepsis. All of the mortality cases had diabetic cardiovascular and nephrologic complications. CONCLUSIONS: We concluded there is a pitfall in managing diabetic patients requiring surgery. There must be a consensus between surgeon and anesthesiologist about perioperative management of diabetics. Perioperative glucose level should be checked as often as feasible, and insulin supply be continued during operation.
