Abstract: Objective: To explore the practicability and effectiveness of the standard blood sampling procedure that suggested in the Clinical Practice Standards for Arterial Blood Gas Analysis in ICU wards. Methods: A before-and-after historical comparison study design was used, and the cost time, success rate and medical cost of the arterial blood collection before and after the implementation of the standard blood sampling procedure were collected and analyzed. Results: The one-time success rate of puncture for arterial blood collection increased from 90% to 97% (χ2=4.031, P=0.045), the defect rate of specimens was lowered (χ2=5.216, P=0.036), the operation time was shortened (t=3.162, P=0.002), and the medical cost for the operation was reduced (t=-2.196, P=0.029) after the implementation of the standard blood sampling procedure in Clinical Practice Standards for Arterial Blood Gas Analysis. Conclusion: The standard blood sampling procedure in Clinical Practice Standards for Arterial Blood Gas Analysis was applicable for arterial blood collection in ICU ward, and it is benefit to save operating costs.
