Abstract

Background: A large difference in blood pressure between both arms is common in patients with disseminated atherosclerosis undergoing vascular surgery. In patients with high cardio-vascular risk, inter-arm blood pressure difference > 10mm Hg can occur in more than 38% of population, but the impact on short-term postoperative complications is still unclear. Objectives: The aim of this study was to evaluate the effect of inter-arm blood pressure asymmetry on the overall postoperative complications in Revised Cardiac Risk Index class I-II patients undergoing peripheral vascular surgery. Secondly, we established other possible risk factors for postoperative complications and duration of hospital stay. Design: Prospective observational study. Setting: Single-centre study. Patients: Ninety-five RCRI class I-II patients undergoing peripheral vascular surgery. Interventions: We measured blood pressure in brachial arteries on both arms in the operating room prior to administering anaesthesia for every patient enrolled in the study. After the surgery, all participants were followed up from the time of hospitalization for any postoperative complications. Main outcome measures: Blood pressure values Results: we did not find any correlation between overall postoperative complications and blood pressure differences (neither systolic, diastolic, nor mean) between the arms. Patients who underwent emergent surgery had highly increased risk of postoperative complications (OR 13,0; 95%CI 1,4 to 69,3; p < 0,01) and prolonged hospital stay time(HR 2,5; 95%CI 1,7 to 3,7; p < 0,01). Conclusion: although we did not find any relevant correlation between inter-arm blood pressure differences and postoperative complications, the measurement in both arms is crucial to determine adequate baseline values prior to surgery.
