To evaluate the effect of daily PIV-based phlebotomy using the PIVO device on PIVC dwell times and replacement rates, as well as the reliability of blood sample collection, and patient response to this method of blood collection.
Blood draws which are also known as phlebotomy for laboratory analyses are one of the most common experiences for hospitalized patients. When performed by venipuncture, they are often associated with pain and anxiety for patients. Most hospitals avoid phlebotomy from peripheral IV catheters due to sample hemolysis, sample dilution by fluids in PIVC line or infused medications, PIVC dislodgement or infiltration, and increased rates of phlebitis.
A prospective, randomized- controlled study of 160 GI surgery patients was enrolled. Patients were randomized to either control evaluation of PIVC dwell or to receive daily PIVO blood collections in addition to evaluation of PIVC dwell.
Daily PIVO blood collections did not negatively affect PIVC dwell or replacement rates. Overall 81% of blood collection attempts were successful and the likelihood of success was strongly associated with PIVC condition. Patients reported 0.7/10 pain for PIVO blood collection on a 0-10 pain scale and a 9.1/10 preference for PIVO on a 0 (strongly prefer needle) to 10 (strongly prefer PIVO) preference scale. Results suggest that use of a PIV based blood collection was a reliable and valid approach and was superior to routine phlebotomy in self-reported responses from patients.
评估使用 PIVO 设备进行基于 PIV 的日常采血对 PIVC 留置时间和更换率的影响，以及血液样本采集的可靠性，以及患者对这种采血方法的反应。
用于实验室分析的血液采集也称为采血，是住院患者最常见的体验之一。当通过静脉穿刺进行时，它们通常会给患者带来疼痛和焦虑。大多数医院避免从外周静脉导管进行采血，因为存在样本溶血、PIVC 管路中的液体稀释样本、PIVC 移位或渗透，以及静脉炎发生率增加等问题。
对 160 例胃肠外科手术患者进行了前瞻性、随机对照研究。患者随机分为对照组评估 PIVC 留置或接受 PIVO 每日采血，同时评估 PIVC 留置。
PIVO 每日采血不会对 PIVC 留置或更换率产生负面影响。总体而言，81%的采血尝试成功，且成功率与 PIVC 状况密切相关。患者报告 PIVO 采血的疼痛程度为 0.7/10（0-10 疼痛评分），对 PIVO 的偏好程度为 9.1/10（0 表示强烈偏好针头，10 表示强烈偏好 PIVO）。结果表明，基于 PIV 的血液采集是一种可靠且有效的方法，在患者的自我报告反应方面优于常规采血。
