The necessity of obtaining a postprocedure chest radiograph after central venous access using the upper extremity or internal jugular veins and interventional radiologic techniques was evaluated.
A prospective study of 937 consecutive central venous access procedures in interventional radiology using the internal jugular veins or upper extremities was performed from June 1995 through September 1997. Established interventional radiologic techniques were used to place various ports (n = 34) and tunneled (n = 670) and nontunneled (n = 233) catheters. All catheters were positioned using fluoroscopy and readjusted if necessary before termination of the procedure. Afterward, a chest radiograph was obtained with the patient upright to evaluate catheter position and possible procedural complications. Procedural complications and manipulations or interventions that resulted from the radiographic findings were noted. In addition, nursing time for acquisition of the chest radiograph was recorded.
We found seven procedural complications (four air emboli, two pneumothoraces, one innominate vein laceration) significant enough to alter the patient's treatment. These complications were apparent during the examination. Postprocedure chest radiography failed to reveal any unknown complications and revealed only one catheter sufficiently malpositioned to require manipulation. The amount of nursing time to acquire postprocedure chest radiographs ranged from 8 to 40 min (mean, 23 min) per patient.
When imaging guidance and interventional radiologic techniques are used for upper extremity and internal jugular central venous access, performing postprocedure chest radiography yields little benefit.
评估在使用上肢或颈内静脉及介入放射技术进行中心静脉置管后拍摄术后胸部X线片的必要性。
对1995年6月至1997年9月间介入放射科连续进行的937例使用颈内静脉或上肢的中心静脉置管操作进行前瞻性研究。采用既定的介入放射技术放置各种端口(n = 34)、隧道式(n = 670)和非隧道式(n = 233)导管。所有导管均在透视引导下定位,必要时在操作结束前进行调整。之后,让患者直立位拍摄胸部X线片,以评估导管位置及可能的操作并发症。记录操作并发症以及由影像学检查结果导致的操作或干预情况。此外,记录获取胸部X线片的护理时间。
我们发现7例操作并发症(4例空气栓塞、2例气胸、1例无名静脉撕裂)严重到足以改变患者的治疗方案。这些并发症在检查过程中即已显现。术后胸部X线片未发现任何未知并发症,仅显示1根导管位置严重不当需要调整。每位患者获取术后胸部X线片的护理时间为8至40分钟(平均23分钟)。
当使用影像学引导和介入放射技术进行上肢及颈内静脉中心静脉置管时,术后进行胸部X线片检查获益不大。
