DOES ANEMIA AFFECT PERIOPERATIVE PAIN INTENSITY IN AGED PATIENTS WITH DIABETIC FOOT SYNDROME?

Background: As diabetes takes on pandemic proportions more than 5 aged (over 50 years) patients undergo pedis amputation yearly. Anemia is very often accompanied diabetes mostly in aged patients. Anemia may influence somehow the pain severity in postoperative period. Objective: To investigate the possible anemia influence on severity of post surgery pain in aged diabetes patients with anemia. Design: A retrospective medical documentation analysis. Setting: Federal scientific centre. Patients: 58 diabetes patients aged from 50 to 75 with and without anemia after elective pedis surgery. Intervention. Patients were allocated to one of four groups: - 16 patients with anemia who received naropin combined with lidocaine for peripheral nerve blockades (I group), 14 patients with anemia who received only naropin (II group), 11 patients without anemia who received naropin combined with lidocaine (III group) and 17 11 patients without anemia who received only naropin. Main outcome measures: Levels of mean arterial pressure, oxygen delivery index, glycaemia and VAS scores were evaluated on four time points: 24 hours before surgery, in operating room, 12 and 24 hours after surgery respectively. Results. VAS scores and levels of mean pressure was higher in anemia groups postoperativly - 3,3±1,50 vs 0,6±0,82 and 101,7±7,81 mm Hg vs 87,9±12,08 mm Hg respectively. Glycaemia levels had no statistically significant differences neither in time points nor in groups. Oxygen delivery index levels also had no differences in time points but levels were significantly different between groups. Conclusion: Taking in account the results of the analysis it is obvious that anemia contributes to the severity of pain in postoperative period in aged diabetes patients somehow. More clinical investigations must be done to evaluate exact portion of anemia contribution.
