Difficulty with removing peripherally inserted central catheters is being encountered with increasing frequency. The most common cause of this phenomenon is venous spasm. Although gentle traction may overcome mild spasm, aggressive pulling is contraindicated. Methods and maneuvers to alleviate spasm are discussed, the simplest of which is to attempt catheter removal again after a short (20 to 30 minutes) or intermediate (12 to 24 hours) length of time, at which time spasm may have spontaneously abated.
外周置入中心静脉导管拔除困难的情况越来越频繁地出现。这种现象最常见的原因是静脉痉挛。虽然轻柔牵引可能克服轻度痉挛,但禁忌用力拉扯。文中讨论了缓解痉挛的方法和操作,其中最简单的方法是在短时间(20至30分钟)或中等时间(12至24小时)后再次尝试拔除导管,此时痉挛可能已自行缓解。
