PURPOSE: To evaluate pulmonary function of patients submitted to muscle flap for treatment of mediastinitis.
METHODS: Fifteen patients operated with the muscle flap technique were compared with 26 consecutive patients submitted to heart surgery with extracorporeal circulation, that did not present wound complications. Both groups were evaluated for age, sex, body weight, height, surgery, forced vital capacity (FVC), forced expiratory volume in first second (FEV1) and the relation (FEV1/FVC) in absolute and percentual values, espirometry conclusions and clinical evidences of lung disease.
RESULTS: There was no statistical difference between preoperative and postoperative period for FVC (p = 0.98), FEV1 (p = 0.68) and FEV1/FVC (p = 0.30) in the group with no sternal complications. In the control group, the median of FVC was 3907 +/- 1053.25 and in the study group was 2818 +/- 766.86 in absolute values (p = 0.0015). The median of FEV1, in the control group, was 2995 +/- 855.68 and in the study group was 2232 +/- 617.68 in absolute values (p = 0.0046). There was statistical difference, between groups, in FVC (104.78 +/- 21.73 and 82.04 +/- 21.16) and FEV1 (99 +/- 22.67 and 79.04 +/- 19.17) in percentual (p = 0.0026 and 0.0067) values. There was no statistical difference for the ratio FEV1/FVC. The study group had five patients diagnosed as having restrictive ventilatory insufficiency by espirometry against none in the control group (p = 0.0031).
CONCLUSION: Patients with infectious complications of sternum and mediastinum, treated surgically with muscle flap rotation may present restrictive pulmonary insufficiency in moderate degree, that must be considered in this situation.
