The midline catheter (MC) is a peripheral venous access device with the catheter tip located in the axilla and available for mid-term intravenous (IV) therapy. This study evaluated the efficacy and clinical outcomes associated with the placement of MCs with an integrated wire-accelerated Seldinger technique for IV access.
A retrospective review was conducted at a single center in South Korea between March 2020 and July 2020. Consecutive patients in whom MC insertions were performed by vascular surgeons were enrolled. The outcomes included catheter indwelling time and incidence of catheter-related adverse events.
Ninety-five patients (117 catheters) were included in the study. The total indwelling time was 1,964 days, with a median of 16.7 days (range, 0-76). The complication-free catheter rates at 5 and 28 days were 92.9% and 65.5%, respectively. Overall, 32 (27.4%) catheters were removed due to complications; however, major complications, such as symptomatic deep venous thrombosis and catheter-induced bloodstream infections, were confirmed in only 3 (2.6%) catheters. A common reason for premature catheter removal is inadvertent removal owing to patient inattention. A high body mass index and female sex were identified as risk factors for short indwelling times and complicated premature catheter removal.
MC insertion is a simple and operator-friendly procedure with a low rate of major complication. It enables mid-term IV treatment through a single procedure if there are no specific complications, thereby improving quality of life of patients during hospital stay.
中线导管（MC）是一种外周静脉通路装置，导管尖端位于腋窝，可用于中期静脉（IV）治疗。本研究评估了采用集成导丝加速塞丁格技术放置MC进行静脉通路的疗效和临床结果。
于2020年3月至2020年7月在韩国的一个单一中心进行了一项回顾性研究。纳入由血管外科医生进行MC插入术的连续患者。结果包括导管留置时间和导管相关不良事件的发生率。
95例患者（117根导管）纳入研究。总留置时间为1964天，中位数为16.7天（范围0 - 76天）。5天和28天的无并发症导管率分别为92.9%和65.5%。总体而言，32根（27.4%）导管因并发症被拔除；然而，仅在3根（2.6%）导管中确认了严重并发症，如症状性深静脉血栓形成和导管相关血流感染。导管过早拔除的常见原因是患者疏忽导致意外拔除。高体重指数和女性被确定为留置时间短和导管过早拔除并伴有并发症的危险因素。
MC插入术是一种简单且对操作者友好的操作，严重并发症发生率低。如果没有特定并发症，通过单次操作即可进行中期静脉治疗，从而改善患者住院期间的生活质量。
