Abstract
Anesthesiologists use different types of catheters in the performance of continuous regional anesthetic techniques such as epidural, subarachnoid, and paravertebral blocks, as well as peripheral nerve blocks.
Epidural catheters may have a single distal orifice located at the tip of the catheter (open-end catheters) or three lateral orifices located lateral to the tip, which is closed and may be oriented in various positions. The use of subarachnoid catheters specifically designed for continuous regional anesthesia or analgesia is less frequent. In the past, the same type of epidural catheter was placed inside both the epidural and subarachnoid spaces.
