Abstract

Our case suggests that gripping an epidural catheter with a hemostat during the removal might result in accidental breakage of the catheter. To demonstrate the effect of the use of a hemostat, tensile strengths of catheters were measured while they were being held with either a stainless steel or rubber-sleeved hemostat.

摘要

我们的病例表明，在拔除硬膜外导管时用止血钳夹持可能会导致导管意外断裂。为了证明使用止血钳的影响，在使用不锈钢或橡胶套止血钳夹持导管时测量了导管的拉伸强度。
