Catheter set for spinal anaesthesia |
摘要 |
A spinal cannula adapted for insertion into an epidural cannula that may be advanced up to the dura. In placing the end of the spinal cannula intrathecally, the dura is pierced by the spinal cannula. Then, a guide wire is advanced to that intrathecal position through the spinal cannula. After removal of the spinal cannula, a spinal catheter is advanced over the guide wire and within the epidural cannula. The epidural cannula imparts the necessary directional stability to the catheter upon its advancement and facilitates the passage through the dura already perforated by the spinal cannula.
