Based on P (cv-a) CO2/C (a-cv) O2 and its changes are associated with an early reduction in multiple organ failure in patients with septic hyperlactocidemia

摘要
The study aimed to investigate the relationship between the respiratory quotient (RQ), measured by the central venous-arterial carbon dioxide partial pressure difference/arterial-venous oxygenation difference ratio, and the early remission of multi-organ failure (MOF) in sepsis patients with hyperlactatemia. The study observed 49 septic patients with hyperlactatemia in the ICU, obtaining blood samples before and after resuscitation, and dividing the patients into two groups depending on whether the modified Sequential Organ Failure Assessment score improved after 24 hours of treatment. Results showed that lactate clearance was faster and the rate of change in RQ was higher in the improved group than in the unimproved group. Further analysis showed that an RQ <= 0.198 mmHg/mL/L or a change of >= 30.71% in RQ after 24 hours of resuscitation was associated with early improvement in MOF. In conclusion, changes in RQ were associated with early improvement in MOF in septic patients with hyperlactatemia, suggesting that RQ could be used as a potential marker for predicting early remission and guiding clinical interventions.
