A retrospective evaluation of 350 axillary and femoral artery cannulations in ICU patients revealed a 6.3-day mean duration of catheterization. Minor incidents such as hematoma (3.7%), catheter malfunction (5.1%), and local inflammation (2.5%) were noticed. The catheter was removed in 25 patients in whom it was suspected of causing sepsis. Six septic patients had the same organism in catheter and arterial blood cultures (with a negative venous blood culture), probably denoting an infected, catheter-linked thrombus. In 241 cases the catheter was removed at the end of the monitoring period. In only 21 of these cases did an organism grow in the catheter culture, but in 18 of these cases, the same organism was found in previous blood, sputum, and/or urine cultures. Thus, in only six patients (of 266 survivors) could arterial cannulation be held responsible for generalized sepsis. However, because no bacteriologic study was performed on catheters removed after the patient's death, this number could have been higher. Percutaneous axillary and femoral artery cannulation is highly recommended for extended monitoring because of its low incidence of minor complications, and no evident danger of tissue ischemia.
对重症监护病房（ICU）患者的350例腋动脉和股动脉插管进行回顾性评估发现，平均插管持续时间为6.3天。注意到有一些轻微事件，如血肿（3.7%）、导管故障（5.1%）和局部炎症（2.5%）。在25例怀疑导管导致败血症的患者中，导管被移除。6例败血症患者的导管血培养和动脉血培养中有相同的微生物（静脉血培养为阴性），这可能表明存在感染性的、与导管相关的血栓。在241例中，导管在监测期结束时被移除。在这些病例中，只有21例导管培养中有微生物生长，但在其中18例中，相同的微生物在之前的血液、痰液和/或尿液培养中也被发现。因此，在266例幸存者中，只有6例患者的全身败血症可归因于动脉插管。然而，由于对患者死亡后移除的导管未进行细菌学研究，这一数字可能更高。由于经皮腋动脉和股动脉插管的轻微并发症发生率低，且无明显的组织缺血风险，因此强烈推荐用于延长监测。
