The importance of liver function assessment before cardiac surgery: A narrative review.

ABSTRACT: The demand for cardiac surgery procedures is increasing globally. Thanks to an improvement in survival driven by medical advances, patients with liver disease undergo cardiac surgery more often. Liver disease is associated with the development of heart failure, especially in patients with advanced cirrhosis. Cardiovascular risk factors can also contribute to the development of both cardiomyopathy and liver disease and heart failure itself can worsen liver function. Despite the risk that liver disease and cirrhosis represent for the perioperative management of patients who undergo cardiac surgery, liver function is often not included in common risk scores for preoperative evaluation. These patients have worse short and long-term survival when compared with other cardiac surgery populations. Preoperative evaluation of liver function, postoperative management and close postoperative follow-up are crucial for avoiding complications and improving results. In the present narrative review, we discuss the pathophysiological components related with postoperative complications and mortality in patients with liver disease who undergo cardiac surgery and provide recommendations for the perioperative management.

Project description:BackgroundMinimally invasive surgery (MIS) is the technique of choice in selected patients for the treatment of liver tumors. The robotic approach is considered today the natural evolution of MIS. The application of the robotic technique in liver transplantation (LT) has been recently evaluated, especially in the living donation. The aim of this paper is to review the current role of the MIS and robotic donor hepatectomy in the literature and to evaluate the possible future implication in the transplant field.MethodsWe conducted a narrative review using PubMed and Google Scholar for reports published so far, using the following keywords: minimally invasive liver surgery, laparoscopic liver surgery, robotic liver surgery, robotic living donation, laparoscopic donor hepatectomy and robotic donor hepatectomy.ResultsSeveral advantages have been claimed in favor of robotic surgery: three-dimensional (3-D) imaging with stable and high-definition view; a more rapid learning curve than the laparoscopic one; the lack of hand tremors and the freedom of movements. Compared to open surgery, the benefits showed in the studies evaluating the robotic approach in the living donation are: less postoperative pain, the shorter period before returning to normal activity despite sustaining longer operation time. Furthermore, the 3-D and magnification view makes the technique excellent in distinguishing the right plane of transection, vascular and biliary anatomy, associated with high precision of the movements and a better bleeding control (essential for donor safety) and lower rate of vascular injury.ConclusionsThe current literature does not fully support the superiority of the robotic approach versus laparoscopic or open method in living donor hepatectomy. Robotic donor hepatectomy performed by teams with high expertise and in properly selected living donors is safe and feasible. However, further data are necessary to evaluate properly the role of robotic surgery in the field of living donation.

Project description:OBJECTIVES:Redox regulation plays a crucial role in balancing the cardiovascular system. In this prospective study we aimed to identify currently unknown correlations valuable to cardiovascular research and patient management. METHODS:Blood samples from 500 patients were collected directly before cardiosurgical interventions (Ethics Committee reference number 85/11). Four central redox parameters were determined together with about 30 clinical, anthropometric, and metabolic parameters. RESULTS:Creatinine levels and pulmonary hypertension were significant predictors of the total antioxidant status (TAOS) in the patients; total glutathione levels were linked to C-peptide, and creatinine, gender, and ventricular arrhythmia influenced nitrate/nitrite levels. Notably, significant interactions were found between medication and redox parameters. Calcium channel blockers (CCBs) were positive predictors of total glutathione levels, whereas angiotensin-converting enzyme inhibitors and CCBs were negative predictors of NOx levels. Age showed the highest correlation with the duration of the intensive care stay, followed by NOx levels, creatinine, TAOS, and C-reactive protein. DISCUSSION:In this prospective study we determined multiple correlations between redox markers and parameters linked to cardiovascular diseases. The data point towards so far unknown interdependencies, particularly between antihypertensive drugs and redox metabolism. A thorough follow-up to these data has the potential to improve patient management.
