Clinical study on the use of one-time arterial blood sampling as an alternative to arteriovenous sampling in critically ill patients
一次性动脉采血替代动静脉采血在危重症患者中的临床研究

摘要

目的 探讨一次性动脉血采集法在危重症患者中的应用效果。方法 纳入2024年5月至11月在ICU同时需采集动静脉血气标本的患者160例，采用随机均分方式分为对照组、观察组各80例；对照组采用常规动静脉分开采血，观察组实施一次性动脉采血，采血指标统计为单例患者人均采血次数，对比两组采血效率与临床相关指标。结果 观察组采血次数及采集时间均显著少于对照组，标本正确率、医生满意度及护士操作体验均优于对照组（P<0.05）。结论 一次性动脉血采集法能够提高危重症患者血气标本获取效率，改善医护操作体验，具有推广价值。

Abstract

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.
