    Abstract:
    OBJECTIVE: The aim of our study is to investigate that sternal reconstruction using bioresorbable plate in median sternotomy may reduce postoperative respiratory dysfunction when compared with wire cerclage only. METHODS: We reviewed 107 patients who were undergone coronary artery bypass grafting with median sternotomy. Patients were divided into two groups; patients underwent sternal reconstruction with bioresorbable plate and wire cerclage (S group, n = 56), patients with wire cerclage only (N group, n = 51), and perioperative respiratory function and postoperative pain score data were analyzed and compared between two groups. RESULTS: There was no significantly difference in preoperative respiratory function in both groups. However, in postoperative change rate of respiratory function, N group had significant decrease compared with S group in vital capacity (VC) (N: S = 74.8 ± 12.4: 85.2 ± 14.8%, p = 0.020), VC as a percentage of predicated VC (N: S = 75.0 ± 12.5: 86.4 ± 15.1%, p = 0.012), and forced expiratory volume in the first second (N: S = 73.7 ± 9.2: 85.3 ± 16.4%, p = 0.012). In Prince Henry Pain Scale, there were significantly more in N group compared with S group (N: S = 3.4 ± 1.0: 2.6 ± 1.4, p = 0.003). CONCLUSION: Sternal fixation with bioresorbable plate could reduce impairment of postoperative respiratory function in comparison to wire cerclage only.
