For decades, intraosseous (IO) access has been a standard of care for pediatric emergencies in the absence of conventional intravenous access. After the recent introduction of a battery-powered IO insertion device (EZ-IO; Vidacare Corporation, San Antonio, TX), it was recognized that a clinical study was needed to demonstrate device safety and effectiveness for pediatric patients.
We measured the insertion success rate, patient pain levels during insertion and infusion, insertion time, types of fluid and drugs administered, device ease of use on a scale of 1 (easy) to 5 (difficult), and complications.
There were 95 eligible patients in the study; 56% were males. Mean patient age was 5.5 +/- 6.1 years. Successful insertion and infusion was achieved in 94% of the patients. Insertion time was 10 seconds or less in 77% of the one-attempt successful cases reporting time to insertion. There were 4 minor complications (4%), but none significant. For patients with a Glasgow Coma Scale (GCS) score >8, mean insertion pain score was 2.3 +/- 2.8, and mean infusion pain score was 3.2 +/- 3.5. The device was rated easy to use 71% of the time (n = 49) and the mean score was 1.4.
The results of this study support the use of the powered IO insertion device for fluid and drug delivery to children in emergency situations. The rare and minor complications suggest that the powered IO device is a safe and effective means of achieving vascular access in the resuscitation and stabilization of pediatric patients.
数十年来,在无法进行传统静脉通路穿刺时,骨内(IO)通路一直是儿科急诊的标准治疗手段。在近期一款电池驱动的IO穿刺装置(EZ-IO;Vidacare公司,得克萨斯州圣安东尼奥市)推出后,人们认识到需要开展一项临床研究来证明该装置对儿科患者的安全性和有效性。
我们测量了穿刺成功率、穿刺及输液过程中患者的疼痛程度、穿刺时间、所输注的液体和药物类型、该装置的易用性(从1分(容易)到5分(困难)进行评分)以及并发症情况。
该研究中有95例符合条件的患者;其中56%为男性。患者平均年龄为5.5±6.1岁。94%的患者成功实现穿刺和输液。在报告穿刺时间的单次穿刺成功病例中,77%的穿刺时间为10秒或更短。出现了4例轻微并发症(4%),但均不严重。对于格拉斯哥昏迷量表(GCS)评分>8的患者,平均穿刺疼痛评分为2.3±2.8,平均输液疼痛评分为3.2±3.5。该装置在71%的时间里(n = 49)被评为易于使用,平均评分为1.4。
本研究结果支持在紧急情况下使用电动IO穿刺装置为儿童输送液体和药物。罕见且轻微的并发症表明,电动IO装置是在儿科患者复苏和稳定过程中实现血管通路的一种安全有效的手段。
