Objective: Verify whether lower preoperative serum albumin levels in cardiac surgery patients increase the incidence of acute kidney injury (AKI), pneumonia, postoperative stay in hospital and mortality. Methodology: A hundred and eighty-five medical records of patients that underwent cardiac surgery between January 2014 and December 2017 were surveyed. The albumin levels were compared between the group that presented at least one of the complications listed above and the group where that complication was not observed. The KDIGO criterion was used to define AKI. Pneumonia diagnosis was established based on clinical, radiologic and laboratory results. The postoperative time in hospital was considered increased when the patient had to stay for a period longer than 8 days. The mortality rate was defined by deaths that occurred up to 30 days after the surgery. Results: Albumin levels ≤3.87 mg/dL were associated to an increase in the risk to develop AKI (p= 0,0072). Albumin values ≤3.91 also increased the chance to have pneumonia (p= 0.0001). However, albumin was not statistically significant to predict mortality and increase in the postoperative stay in hospital. Conclusion: Serum albumin levels that were lower than or equal to 3.91 mg/dL and 3.87 mg/dL increased, respectively, the chances of developing both pneumonia and acute kidney injury after cardiac surgery. No significant results were obtained regarding albumin levels influence on postoperative stay in hospital or mortality.

Objective: To evaluate the perioperative risk factors associated with postoperative AKI in patients undergoing cardiac surgery. Methodology: Between January 2011 and December 2017, we analyzed prospectively 544 patients, who were divided into two groups: patients with acute kidney injury associated with cardiac surgery (AKI-ACS) defined as an increase of 0.3 mg/dL or 1.5 times the baseline serum creatinine value and control group formed by patients without AKI-ACS. We compared patients and surgical variables using the chi-square test, Fisher's exact test, and mann-Whitney test and logistic regression. Results: AKI-ACS occurred in 29.8% of the patients. In the univariate analysis, the following variables presented a statistically significant difference: male gender (p=0.0087), age (p<0.0001), body mass (p=0.035), BMI (p=0.001), thoracic aortic surgery (p=0.029), use of extracorporeal circulation (p=0.012), CPB time (p=0.0001), aortic clamping time (p=0.0029), use of vasoactive drugs in post-operative period (p=0.017), preoperative kidney function (p<0.0001), presence of diabetes mellitus (p=0.008) and NYHA functional class (p=0.041). In the multivariate analysis, the following variables presented a statistical difference: male gender (OR 2.11), higher BMI (OR 2.11), worse preoperative renal function, demonstrated by creatinine clearance (OR 0.13), longer cardiopulmonary bypass (OR 1.008). Conclusion: The independent predictors for LRA-ACC were male gender, higher body mass index, worse preoperative renal function, and more complex surgeries associated with longer cardiopulmonary bypass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
