Aim. According to some reports the destruction the integrity of the pleura during acute myocardial infarction (AMI) harvesting during coronary surgery may also impair respiratory function in the postoperative period. The purpose of this study was to evaluate the influence of preserved integrity of pleura on respiratory function in patients undergoing coronary artery bypass grafting (CABG).
Methods. One hundred and forty-three patients who had on-pump-CABG operation with pedunculated LIMA graft were divided to 2 groups. The first group is the study group that pleura opened (group OP; N=69), and the other group is that their pleura protected (group C, N=74). All patients were evaluated with using respiratory function test parameters (functional vital capacity [FVC], force expiratory volume %-at the 1st second [FEV1%] in the preoperative period and on the 7th postoperative day). Respiratory problems, blood drainage amounts and used blood products in the postoperative period were measured.
Results. Preoperative FVC values were not different between the two groups (3.08±0.5 in group C and 3.37±0.7 L in OP group) (P>0.05). On the VII postoperative day this parameter did not show any significant difference between the groups (2.80±0.6 in group C and 2.75±0.5 liter in OP group) (P>0.05). Preoperative FEV1% values did not show any difference (77.6±4.6% and 76.0±2.7% in OP and C groups respectively. There was no significant difference between the postoperative FEV1% values (71.8±5.1% and 73.4±6.3% respectively) (P>0.05). Patients with protected pleura had significantly lower blood drainage and whole blood unit transfusion (P<0.05).
Conclusion. Preservation of the pleural integrity during LIMA harvesting significantly reduces postoperative bleeding but not affects pulmonary functions.
