Background and aim: This study was carried in order to investigate the degree of agreement and correlation between arterial and venous blood gas parameters and the possibility of replacing intravenous blood instead of arterial blood gas test according to scientific evidence.
Methods: This narrative review was done by searching the databases of SID, PubMed, Web of Science, Scopus and Google Scholar search engine, using the keywords arterial blood gases, venous blood gases from 2005 to 2020. A total of 24 related articles were found and after screening, 16 articles were reviewed and analyzed.
Results: Review of studies examining the correlation of the agreement between ABG and VBG parameters often found a good relationship, especially between the PH and HCO3 values of arterial and venous blood. The use of intravenous PCO2 instead of arterial blood, although some studies have introduced intravenous PCO2 as an acidemy screening tool, is still debated and needs further study.
Conclusion: Venous blood gas test can be a safe, easy and low-cost option to assess patients' blood gas status. However, considering the clinical condition of patients when using VBG is recommended and ABG analysis will commend only if necessary. |
