High central venous-to-arterial CO2 difference/arterial-central venous O-2 difference ratio is associated with poor lactate clearance in septic patients after resuscitation

摘要

Objective: Recently, the central venoarterial carbon dioxide difference/arterial-central venous oxygen difference (P(v-a)CO2/C(a-v)O-2) ratio has been suggested as an additional indicator of anaerobic metabolism. We investigated the relationship between the P(v-a)CO2/C(a-v)O-2 ratio and 8-hour lactate clearance (LC) in septic patients after resuscitation.
