Evaluation of an Arterial Blood Sampling Device and Its Function in Accelerating and Facilitating Blood Sampling

Background: Arterial blood sampling is among the basic standards in criticallyill patients. The aim of this study was to examine an inventive sampling devicein facilitating arterial blood sampling in comparison to the conventional methodusing an insulin syringe.Methods and materials: This randomized interventional clinical trial wasperformed on 100 patients admitted to Qaem and Imam Reza Hospitals inMashhad in 2016 for whom two arterial blood gas (ABG) samples wereindicated. The patients were randomly selected by the visiting operator on adaily basis. The operator visited the hospital on certain days and took twosamples from the selected patients.Results: The patients mean age was 45.31±16.15 years. In the insulin syringegroup, venous blood gas sampling was in 24% and arterial sample in 76%. Inthe designed device group, same figures were 12.1% and 87.9%, respectively.Sampling score (p=0.01), unsuccessful attempts with and without needleremoval from the skin (p=0.01), and need for vertical and horizontal needledisplacement for sampling (p=0.01) were significantly differed between thetwo groups. Localized swelling score and its size, localized bruising, palpablearterial spasm and the spasm duration was significantly less for the inventivedevice (p<0.05). Satisfaction score of patients and operator were significantlyhigher in the device group (p=0.01).Conclusion: The study device had desirable function in facilitating andaccelerating arterial blood sampling. Its application can be further approved byfuture studies.
