Abstract

Background: Urinary Output (UO) is an important observation among patients following cardiac surgery that has been linked to adverse cardiovascular events in various populations. However, its correlation with durations of hospitalization and ventilation has rarely been reported among patients following cardiotomy. In addition, how does the timing of UO correlate with durations of hospitalization and ventilation? This question has also not been addressed.Methods: This retrospective study included the medical records of 458 patients who underwent various types of cardiovascular surgery between March 2015 and May 2017. Hospitalization and ventilation durations were analyzed as indicators to estimate patient status. Patients were grouped according to the means of continuous variables. Correlation between UO values obtained at 6 h, 12 h, and the first, second, and third 24 h with the durations of hospitalization and ventilation were analyzed. In addition, the risk factors affecting impaired UO were also analyzed.Results: We analyzed 77 patients who had undergone Coronary Artery Bypass Grafting (CABG) (16.8%), 231 with heart valve surgery (50.4%), 16 with congenital heart surgery (3.5%), 41 with thoracic aorta surgery (9%), 61 with CABG plus valve surgery (13.3%), 13 with congenital heart plus valve surgery (2.8%), and 19 who underwent other types of heart surgery involving cardiopulmonary bypass (4.1%). The overall mortality rate was 2.8%; the mean postoperative hospitalization duration was 21.7 days, and the mean duration of ventilation was 30.6 h. Mean UO values at 6 h, 12 h, and the first, second, and third 24 h were 1286.5 mL, 1906.5 mL, 3308.9 mL, 3181.5 mL, and 3451.0 mL, respectively. Univariate analysis indicated that reduced UO values at 6 h, 12 h, and the first 24 h were significantly correlated with hospitalization and ventilation durations. A multiple linear regression analysis showed that preoperative albumin level and cross-clamping time were risk factors predicting impaired UO values at 6 h, 12 h, and the first 24 h.Conclusion: This study indicated that reduced UO values at 6 h, 12 h, and the first 24 h were correlated with the durations of hospitalization and ventilation, patients with poor early UO extended durations of hospitalization and ventilation. Thus, UO as an observation of patients following cardiotomy might serve as a meaningful predictor of their status.
