A prospective, randomised study of 82 patients having postoperative epidural analgesia was performed to determine whether the tunnelling of an epidural catheter influences its migration. Tunnelling of the catheter subcutaneously for a distance of 5 cm reduced the incidence of inward migration of 1 cm or more (p < 0.01) compared to a standard method of fixation with a transparent adhesive dressing. This effect was more marked if the epidural catheter was sited in the thoracic rather than the lumbar area. Sixty two percent (n = 26) of tunnelled catheters remained within 0.5 cm of their original position compared to 38% (n = 16) of non-tunnelled catheters, although this difference was not statistically significant. Outward catheter migration was not reduced by subcutaneous tunnelling.
对82例行术后硬膜外镇痛的患者进行了一项前瞻性随机研究，以确定硬膜外导管的隧道式置入是否会影响其移位。与使用透明粘性敷料的标准固定方法相比，将导管在皮下隧道式置入5 cm可降低1 cm或以上向内移位的发生率（p<0.01）。如果硬膜外导管位于胸部而非腰部区域，这种效果更明显。62%（n=26）的隧道式导管保持在其原始位置0.5 cm范围内，而非隧道式导管为38%（n=16），尽管这一差异无统计学意义。皮下隧道式置入并未减少导管向外移位。
