We prospectively evaluated the use of peripherally inserted central venous catheters to provide ongoing venous access in general medical and surgical patients in a Department of Veterans Affairs medical center. Between 1985 and 1988 trained nurses successfully inserted 393 catheters in 460 suitable patients (an 85.4% success rate). Correct catheter tip placement in the superior vena cava was documented in 359 of the 393 (91.3%) catheter insertions, but an additional 30 catheters were in a position deemed adequate for the intended use. The mean duration of catheter use was 27.6 +/- 5.2 (1 standard deviation) days (median 20 days, range 1 to 370 days). A total of 65 patients left the hospital with catheters in place, with the mean length of catheter use at home being 36.2 +/- 6.0 days (range 2 to 266). In all, 79% of the catheters were in use until the successful completion of therapy or patient death; catheter-related complications led to premature catheter removal in the remaining 21%. Catheter-related complications included bland phlebitis (8.2%), occlusion (8.2%), local infection (3.6%), bacteremia or fungemia (2.1%), mechanical failure or rupture (2.6%), venous thrombosis (0.7%), and other (3.3%). One patient required vein excision for the management of suppurative phlebitis, but no deaths were attributed to catheter use. This study illustrates the use and safety of peripherally inserted central venous catheters to provide reliable vascular access over prolonged periods in an elderly veteran population. At our facility, percutaneous central venous catheters and surgically implanted (Hickman or Broviac) catheters are now reserved for use in patients in whom peripherally inserted catheters cannot be placed.
我们前瞻性评估了在一家退伍军人事务部医疗中心,为普通内科和外科患者使用外周静脉穿刺中心静脉导管(PICC)以提供持续静脉通路的情况。1985年至1988年间,经过培训的护士在460例合适的患者中成功插入了393根导管(成功率为85.4%)。在393次导管插入操作中,有359次(91.3%)记录显示导管尖端正确置于上腔静脉,但另有30根导管的位置被认为对于预期用途是足够的。导管使用的平均时长为27.6±5.2(1个标准差)天(中位数为20天,范围为1至370天)。共有65例患者出院时仍保留导管,在家中导管的平均使用时长为36.2±6.0天(范围为2至266天)。总体而言,79%的导管一直使用至治疗成功完成或患者死亡;其余21%的导管因与导管相关的并发症而提前拔除。与导管相关的并发症包括非感染性静脉炎(8.2%)、堵塞(8.2%)、局部感染(3.6%)、菌血症或真菌血症(2.1%)、机械故障或破裂(2.6%)、静脉血栓形成(0.7%)以及其他(3.3%)。1例患者因化脓性静脉炎的处理需要进行静脉切除,但没有死亡病例归因于导管使用。本研究表明,外周静脉穿刺中心静脉导管在老年退伍军人人群中能够长期提供可靠的血管通路,且具有安全性。在我们的机构中,经皮中心静脉导管和外科植入式(希克曼或布罗维阿克)导管现在仅用于无法放置外周静脉穿刺导管的患者。
