The compari'son of the transcutaneous and arteri?al blood gases in the septic patients

The arterial blood gas analysis which is known as a gold standard is an important observing method in the systemic oxygenation of sepsis patients. However, because the blood gas analysis is invasive and it has the special potentials of complications, it directs the investigators to the new methods which are less invasive and noninvasive. It is aimed to compare the effectiveness of non-invasive blood gas monitoring and arterial blood gas analysis. After the diagnosis of sepsis, the patients were divided into two groups as Group-sepsis (Group-S); the patients who didn?t received inotropic agents and Group-inotropic agents (Group I); the patients who received inotropic agents. After the recordings of transcutaneous blood gas analysis and the synchronic blood gas samples were compared at baseline, 1.h, 2.h, 3.h and 4.h. A great correlation was observed in transcutaneous (PtcO2, PtcCO2) and arterial (PaO2, PaCO2) blood gas analysis in both groups. Only in group I there was a middling-high correlation between PtcO2 and PaO2. In group S, there wasn?t difference between the synchronic values of PtcO2 and PaO2 at 1.h, 2.h, 3.h and 4.h. However, there was a difference in group I in respect of same parameters. In Addition, there was a difference in the measurements of PtcO2 and PaO2 in both groups. It was concluded that the monitoring of transcutaneous blood gas analysis effective in the observation in the mild septic patients but it can?t be confident as invasive blood gas monitoring in severe sepsis patients receiving inotropic agents.
