Objective To evaluate the application effect of one-time arterial blood collection in critically ill patients. Methods A total of 160 patients who needed to collect arterial and venous blood gas specimens simultaneously in the ICU from May to November 2024 were included. They were randomly divided into the control group and the observation group, with 80 cases in each group. The control group used the conventional separate arterial and venous blood collection, while the observation group implemented one-time arterial blood collection. The statistics of blood collection indicators were the average number of blood collections per patient. The blood collection efficiency and clinical related indicators of the two groups were compared. Results The observation group exhibited significantly fewer blood collection attempts and shorter collection times compared to the control group, with higher specimen accuracy, physician satisfaction, and nursing operational experience (P<0.05). Conclusion The one-time arterial blood collection method enhances the efficiency of blood gas specimen acquisition in critically ill patients, improves the operational experience for medical staff, and demonstrates potential for widespread adoption.
