Midline catheters provide an effective alternative for intermediate-term intravenous therapy. During a pilot study, 27 midline catheters were inserted in patients who met specific criteria. The insertion success rate was 64%, and the infection rate was 7%. One mechanical phlebitis occurred, but it was resolved by the application of warm, moist heat. One chemical phlebitis occurred during antibiotic therapy. The average dwell time was 8.7 days, and the longest dwell time was 49 days. Patients reported the catheters to be very comfortable and did not experience limitations in mobility.
中线导管为中期静脉治疗提供了一种有效的替代方法。在一项试点研究中，为符合特定标准的患者插入了27根中线导管。插入成功率为64%，感染率为7%。发生了1例机械性静脉炎，但通过应用温热湿敷得以解决。在抗生素治疗期间发生了1例化学性静脉炎。平均留置时间为8.7天，最长留置时间为49天。患者报告导管非常舒适，且活动不受限。
