Randomized Controlled Trial Clinical Trial
[Usefulness and radiopacity of the two radiopaque epidural catheters].
We evaluated the radiopacity and usefulness of the two radiopaque epidural catheters, one by Portex CO. Ltd., and the other Flex Tip Plus with a stainless coil by Arrow Japan Co. Ltd. ⋯ The course of the catheter was identified easily in 1 case of Group A and 4 cases of Group B but was not identified at all in 10 cases of Group A and 8 cases of Group B. There were no differences between the two groups in the number of patients in whom the catheter was easily inserted, identified, or placed straight. Therefore, the usefulness of the two catheters in terms of insertion and identification of its course was not different.
