Standard	Advances	Gaps	Evidence for practice	Search recommendations
Hypoperfusion/Tissue hypoxia	The important role of perioperative tissue hypoxia in the development of postoperative complications	Some factors related to sample size, data and validity compromise the quality of the studies.	The study is relevant for helping and alerting the healthcare team about possible complications after heart surgery.	It is necessary to carry out additional studies in this line to guarantee the results of the data.
CPB time	Prolonged CPB time and other factors are associated with early and late postoperative hyperlactatemia.	Studies with small samples of participants, harmful to inferring results	The study contributes to the health team’s performance regarding postoperative results, depending on the patient’s physiological needs.	More research on this topic with larger sample sizes is needed.
Use of drugs	Inadequate intraoperative infusion of high-dose medications is an independent risk factor for lactic acidosis after cardiac surgery.	Few studies address the relationship between specific drugs and increased lactate.	Evaluates the risk-benefit of intraoperative drug use.	Studies with different drug therapy approaches are needed for a more comprehensive investigation.
