In the emergency department (ED), intravenous (IV) catheter placement is one of the most frequent interventions and may be a real challenge in some conditions. Improvement of the success rate with new technology represents a great opportunity. This randomized controlled trial aimed to show the superiority of AccuVein to cannulate veins in adults compared to routine care.
After giving written consent, patients were randomized into two groups: routine IV catheter insertion or insertion guided by the AccuVein, which is a hand-held instrument displaying laser light to optimize visualization of veins. The primary outcome was the time to successful placement of catheters. Secondary outcomes included the number of attempts, the rate of failure, technique-related pain, occurrence of movements, and efficiency of IV cannulation as perceived by the operator when using the AccuVein device. Results are given as mean and bootstrapped 95% confidence interval (CI) and percentages. p-values of <0.05 were considered significant.
A total of 266 six patients were included, with 157 randomized to routine cannulation and 115 to AccuVein. Patient characteristics were similar. Time to successful placement of IV catheter (routine, 98 seconds, 95% CI = 85 to 113 seconds; and AccuVein, 119 seconds, 95% CI = 93 to 154 seconds) was not different between groups (p = 0.24). Secondary outcomes (failure and pain) did not significantly differ, except for movements, which were more frequent when using the AccuVein device (19.1% vs. 10.2%, p = 0.05). Evaluation of the AccuVein by operators was more often negative than positive.
Use of the AccuVein did not improve IV cannulation in nonselected ED patients.
在急诊科(ED),静脉(IV)置管是最常见的干预措施之一,但在某些情况下可能极具挑战性。新技术的成功率提高是一个巨大的机会。这项随机对照试验旨在证明 AccuVein 在成人静脉置管方面优于常规护理。
患者书面同意后,随机分为两组:常规 IV 导管插入或 AccuVein 引导下插入,AccuVein 是一种手持式仪器,可显示激光以优化静脉可视化。主要结局是成功放置导管的时间。次要结局包括尝试次数、失败率、与技术相关的疼痛、运动发生情况以及操作者使用 AccuVein 设备时对 IV 置管的效率的感知。结果以平均值和引导 95%置信区间(CI)和百分比表示。p 值<0.05 被认为具有统计学意义。
共纳入 266 名患者,其中 157 名随机分为常规置管组,115 名随机分为 AccuVein 组。患者特征相似。IV 导管成功放置时间(常规组,98 秒,95%CI=85 至 113 秒;AccuVein 组,119 秒,95%CI=93 至 154 秒)在两组之间无差异(p=0.24)。次要结局(失败和疼痛)没有显著差异,除了运动,使用 AccuVein 设备时更频繁(19.1%比 10.2%,p=0.05)。操作者对 AccuVein 的评估更多是负面的而不是正面的。
在非选择性 ED 患者中,使用 AccuVein 并未改善 IV 置管。
