Aim and Background: Stress of surgery transfers some neurological and hormonal signalsudwhich triggers some physiological responses like adrenergic stimulation, increase in noradrenalin,udcortisol, growth factor, decrease in insulin and increase in insulin resistance resultingudin hyperglycemia during surgery. In this study a comparison is done between general anesthesiaudwhich by blocking brain's signals decreases reactions to the stress of surgery and hyperglycemia,udand spinal analgesia which blocks hormonal and adrenergic reactions by peripheral effect.udMethods and Materials: This randomized control clinical trial study was performed on 60 ASAudI, II patients candidate of inguinal hernioraphy. The patients were randomly allocated to generaludanesthesia or spinal anesthesia with T12 level. Blood sugar of the patients was measured byudglucometer 1 hour before the surgery and 1 hour and 6 hours postoperatively.udFindings: There was no significant difference in blood sugar levels before the surgery betweenudtwo groups but it was lower 1and 6 hours postoperatively in spinal anesthesia group.udConclusions: Spinal analgesia more effectively controls rises in blood sugar during the surgery and mayudbe a suitable alternative for general anesthesia in patients with metabolic disorders.
