Understanding lactate and its clearance during extracorporeal membrane oxygenation for supporting refractory cardiogenic shock patients

[1] entitled ‘Association between serum lactate levels and mortality in patients with cardiogenic shock receiving mechanical circulatory support: a multicenter retrospective cohort study’, published in the BMC Cardiovascular Disorders evaluates the prognostic role of serum lactate and lactate clearance over time in cardiogenic shock patients treated with mechanical circulatory support. [...]the contextual interpretation of the findings in a complex and dynamic concept of lactate clearance during cardiogenic shock remains unclear. [...]studies focusing on the dynamics of oxygen debt repayment rather than solely lactate levels and its clearance will be valuable to understand this complex topic during temporary mechanical circulatory support.
