Abstract:

To present our results in patients with chronic obstructive pulmonary disease (COPD) who underwent off-pump and on-pump coronary artery bypass graft (CABG) surgeries in our clinic. A total of 52 patients suffering from COPD (FEV1 / FVC ≤ 0.7) and treated with CABG between January 2014 and December 2017 in our clinic were included in the present study. Of 52 patients, 27 patients who underwent off-pump CABG were designated as Group 1 and 25 patients treated with on-pump CABG were designated as Group 2. Anamnesis, physical examination findings, chest X-rays, spirometric measurement findings and arterial blood gases of all the patients were evaluated. The patients in both groups were compared with operation-related data and postoperative data. There was no difference between groups in terms of age, gender, smoking, hypertension, diabetes, hyperlipidemia and additional diseases. Similarly, there was also no difference between preoperative spirometry values and partial oxygen saturation in arterial blood gases. The duration of mechanical ventilatory support, inotropic support, steroid and bronchodilator use, intensive care unit and length of hospital stay were statistically significantly higher in Group 1. Whereas, bronchospasm and atelectasis due to the complications were significantly lower in Group 1. Other complications were less significant in Group 1 even though not statistically significant. Ultimately, while there was no mortality in Group 1, there was one mortality in Group 2. We believe that off-pump coronary bypass surgery without COPD in COPD patients may significantly reduce morbidity and mortality.
