Abstract :Objective: The laser speckle contrast imaging insert ignore into journalissuearticles values(LSCI); system is a method to evaluate microcirculation. The primary aim of our study is to evaluate the relationship between LSCI and perfusion markers in coronary artery bypass grafting insert ignore into journalissuearticles values(CABG);. Our second aim is to investigate the relationship between LSCI and extubation time in the intensive care unit. Patients and Methods: Fifteen patients aged 43-80 years who will undergo on-pump CABG were included in the prospective study. Mean arterial pressure insert ignore into journalissuearticles values(mmHg);, heart rate insert ignore into journalissuearticles values(min-1);, PO2 insert ignore into journalissuearticles values(mmHg);, PCO2 insert ignore into journalissuearticles values(mmHg); and lactate insert ignore into journalissuearticles values(mmol/L); levels were measured preinduction, post-induction, 10th minute of the extracorporeal circulation, post-crossclamp, and post-operatively. At the same time points, LSCI values from the skin were measured and recorded. The intubation times of the patients were also recorded. Results: There was no significant change in systemic tissue perfusion markers insert ignore into journalissuearticles values(P>0.05);. LSCI perfusion values decreased significantly from induction and remained low until the end of surgery insert ignore into journalissuearticles values(P<0.05);. The perfusion value insert ignore into journalissuearticles values(98±11 PU); of the patients who were intubated for less than 8 hours was better than the perfusion value insert ignore into journalissuearticles values(52±4.8 PU); of the patients who were intubated for more than 8 hours insert ignore into journalissuearticles values(P<0.05);. Conclusion: In our study, a significant change occurred in skin tissue perfusion before systemic perfusion parameters in CABG, and low perfusion was associated with prolonged intubation time.
