Six Minutes-Walk Test and Respiratory Function Tests Predict Complications and Mortality in Coronary Artery Bypass Grafting?

The purpose of the study was to assess the influence of physiotherapeutic devices on respiratory system function after coronary bypass grafting. The tasks of the study: 1. To assess and compare the factors of the respiratory function on the first group (physiotherapist employed physiotherapy once a day) and in the second group (physiotherapist employed physiotherapy twice a day). 2. To compare the factors of the respiratory function and the frequency of post-operative complications between non-smokers and smokers in the first and the second group. The study included 40 patients after coronary artery bypass grafting in the Cardiac, thoracic and vascular clinic in the hospital of Kaunas University of Medicine. The studied patients were distributed into two equal groups. The first group received physiotherapy once a day; the second group received physiotherapy twice a day. In this study we measured the factors of the respiratory function (the respiratory rate and the Hence sample) on the first and the eighth post-operation days. The patients case-histories provided the data about atelectasis. The patients were inquired whether they smoked during six weeks before the operation. We found that on the sixth day after the operation the values of the indicators of the respiratory function (the respiratory rate and the Hence sample) in the second group were significantly better (p < 0.05) than the values of the analogous indicators in the first group. Consequently it is advisable to apply physiotherapeutic procedures twice a day to the coronary artery bypass grafting patients. Smoking was contributed to development of such post-operative complications as atelectasis. We found that the values of the respiratory function indicators (the respiratory rate and the Hence sample) in non-smokers were significantly (p < 0.05) better than in the patients' who smoked (p < 0.05).Keywords: ischaemical heart disease, coronary artery bypass grafting, post-operative complications of respiratory function, smoking, physiotherapy

Pump Coronary Artery Bypass

Background: Respiratory complications are common after cardiac surgery and the use of extracorporeal circulation is one of the main causes of lung injury. We hypothesized a better postoperative respiratory function in off-pump coronary artery bypass grafting (OPCABG) as compared with “on-pump coronary artery bypass grafting” (ONCABG). Methods: This is a retrospective, single-center study at a cardiothoracic intensive care unit (ICU) in a tertiary university hospital. Consecutive data on 339 patients undergoing elective CABG (n = 215 ONCABG, n = 124 OPCABG) were collected for 1 year from the ICU electronic medical records. We compared respiratory variables (Pao2, Pao2/Fio2 ratio, Sao2, and Paco2) at 7 predefined time points (ICU admission, postoperative hours 1, 3, 6, 12, 18, and 24). We also evaluated time to extubation, rates of reintubation, and use of noninvasive ventilation (NIV). We used mixed-effects linear regression models (with time as random effect for clustering of repeated measures) adjusted for a predetermined set of covariates. Results: The values of Pao2 and Pao2/Fio2 were significantly higher in the OPCABG group only at ICU admission (mean differences: 9.7 mm Hg, 95% confidence interval [CI] 3.1-16.2; and 27, 95% CI 6.1-47.7, respectively). The OPCABG group showed higher Paco2, overall ( P = .02) and at ICU admission (mean difference 1.8 mm Hg, 95% CI: 0.6-3), although mean values were always within normal range in both groups. No differences were seen in Sao2 values, time to extubation, rate of reintubation rate, and use of postoperative NIV. Extubation rate was higher in OPCABG only at postoperative hour 12 (92% vs ONCABG 82%, P = .02). Conclusion: The OPCABG showed only marginal improvements of unlikely clinical meaning in oxygenation as compared to ONCABG in elective low-risk patients.
