Arter kan gazi ve venöz kan gazi korelasyonuna apache II skoru ve inotrop kullaniminin etkisi

Abstract

Objective: Blood gas analysis has an important role in management of critically ill patients with respiratory and metabolic diseases. In this study, our aim is to show correlation between arterial and venous blood gas analysis and determine effects of inotropic agent consumption and APACHE II scores on this correlation. Method: Sixty-five patients followed with sepsis in intensive care unit with mechanical ventilation support were conducted in the study. Ph, pO2, pCO2, HCO3, lactate and SpO2 levels of blood gas analysis, APACHE scores and consumption of inotropic agents were recorded. Results: A strong correlation between mean arterial and venous pH levels was detected, whereas correlation for pO2 levels couldn't be found. There was no correlation between mean arterial and venous pCO2 levels, but when no need for inotropic agents, a statistically significant correlation could be detected. There was a strong correlation between mean arterial and venous HCO3- and lactate levels. Conclusion: Arterial blood gas analysis continues to be gold-standart for patients who need close monitorization of oxygenation. But we believe venous blood gas analysis may be useful in case arterial blood sample can not be provided when there is no need for inotropic agent and pCO2 follow-up is more important.
