The incidence of AKI worldwide ranges between 20 and 200 cases per million population. Sepsis and septic shock contribute to 25-75% of AKI cases. Regardless of the cause, loss of fluid and electrolyte homeostasis and the accumulation of nitrogenous wastes lead to uremia, hyperkalemia, water and sodium retention, and metabolic acidosis. Renal replacement therapies (RRT) aim to mitigate these effects and prevent death associated with kidney failure. There are various modalities of RRT, including intermittent hemodialysis, continuous RRT, as well as different solute elimination techniques.

However, CPB presents adverse effects at a local and systemic level because its components produce alterations at the macro- and microcirculation levels, potentially leading to hypoperfusion. The goal-directed perfusion (GDP) technique seeks to personalize hemodynamic management according to predefined goals, thereby optimizing tissue oxygenation and perfusion during CPB. This implies constant monitoring of key parameters, to make real-time changes to perfusion strategies. Over the past 10 years, the benefits of using GDP have been explored and its superiority over the traditional approach visualized. The objective of this article is to describe GDP practice in monitoring during CPB. We will focus on the existing variables monitored under the GDP concept, applying and manipulating them to optimize tissue perfusion in real-time.</p></div>","PeriodicalId":31544,"journal":{"name":"Revista Medica Clinica Las Condes","volume":"35 1","pages":"Pages 8-13"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0716864024000026/pdfft?md5=cd170c1a814ed9c7e318dcc5223097bd&pid=1-s2.0-S0716864024000026-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139699956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
