Clinical efficacy of digital chest drainage system in cardiac valve surgery

Objects The portable digitalized suction was used widely in thoracic surgery. The aim of the study was to access the early outcomes of using the portable digitalized suction system after cardiac surgery. Methods We invested 80 patients including 30 women (mean age 72.7 +/- 9.2 years) who underwent cardiac surgery at our hospital, excluded coronary artery bypass grafting only, with or only aortic surgery, emergency operation, and patients with hemodialysis. Patients were categorized as those treated with digital chest drainage system (DCS group, n = 38) or analog chest drainage system (ACS group, n = 42), and the following data were analyzed in two groups. The primary endpoint was the duration of chest drainage, and the secondary endpoints were the rate of drainage-related complications and the length of hospitalization. Results The duration of drainage was significantly shorter in the DCS group (ACS vs. DCS = 94.8 +/- 31.5 vs. 81.1 +/- 20.6 h, p = 0.036). The duration needed for rehabilitation completion was significantly shorter in the DCS group (ACS vs. DCS = 10.7 +/- 1.2 vs. 9.6 +/- 1.5 days, p = 0.047), and the length of hospitalization was significantly shorter in the DCS group (ACS vs. DCS = 21.9 +/- 5.3 vs. 18.8 +/- 7.2 days, p = 0.031). Conclusions This study provided evidence that DCS might be effective for patients who underwent cardiac valve surgery.
