Özet
Background: Arterial blood gas analysis is vital during diagnosis and treatment monitorization of mechanically ventilated patients. Work overload delays blood gas analysis lead to false results. Therefore syringes and the blood samples is recommended to kept cool or cold environment. The aim of this study is to investigate the effect of refrigerator-cooled syringes on blood gas analysis. Methods: We prepared 12 heparinized polypropylene plastic syringes for blood gas analysis for each patients before the study. Syringes divided in tree group as kept at room temperature (Group Room, n=4), or stored in the refrigerator for 30 minutes (Group Refrigerator, n=4), or stored in the refrigerator for 30 minutes but blood samples stored at room temperature (Group Refrigerator and Room, n=4). 40 for each patient's blood samples on mechanical ventilation were analyzed immediately as reference value (T-0). Samples analyzed at 15, 30, 45 and 60 minutes. Results: Patients characteristics and mechanical ventilation parameters were similar in the three groups. In terms of impact of sample temperature and storage time on arterial blood gas analysis; pH, pCO(2), and pO(2) values were not differ significantly among the groups (Table 2, P>0.05). There was significant difference in 60 minutes SpO(2) value among the groups (Table 2, P<0.05). Conclusion: Storage of syringes at room temperature or cooling in refrigerator was not affect arterial blood gas analysis results immediately before obtaining of blood samples. Blood gas analysis with plastic syringes at room temperature can provide safe results up to 60 minutes.
