We tested a new epidural catheter, which is made of a stainless steel spiral (similar to an anode endotracheal tube) covered with a fluorpolymer. This catheter was tested in 15 patients who were administered lumbar epidural anaesthesia for pain relief during labor. We also have information on the evaluation of this catheter in about 100 patients from the obstetric anesthesia service, Stanford-University Medical Center. The main advantage of this catheter is, that it does not kink. The disadvantages are: 1. catheter leakage either at the skin interface or just below the injection port particular after prolonged usage, 2. difficult or impossible injection if the catheter injection port is screwed on too tight which requires cutting the catheter (not recommended by the manufacturer), 3. a 17 gauge rather than a 18 gauge epidural needle is recommended and 4. the high price of the catheter.
我们测试了一种新型硬膜外导管，它由覆盖有含氟聚合物的不锈钢螺旋管（类似于阳极气管导管）制成。该导管在15名接受腰椎硬膜外麻醉以缓解分娩疼痛的患者中进行了测试。我们还掌握了斯坦福大学医学中心产科麻醉科对约100名患者使用该导管的评估信息。这种导管的主要优点是不会打结。缺点包括：1. 尤其是长时间使用后，在皮肤接口处或注射端口下方会出现导管漏液；2. 如果导管注射端口拧得太紧，注射困难或无法注射，这需要剪断导管（制造商不建议这样做）；3. 建议使用17号而非18号硬膜外穿刺针；4. 导管价格高昂。
