Abstract

Background: Continuous epidural catheterization is a popular and effective procedure for postoperative analgesia. However, continuous epidural catheterization has associated complications such as venous puncture, dural puncture, subarachnoid cannulation, suboptimal catheter placement, and paresthesia because the tip of the epidural catheter touches thenerves of the dura in the epidural space. In this study, we compared the incidence of paresthesia in two different lengths of epidural catheter insertion. Methods: One hundred women undergoing gynecologic or orthopedic surgery were enrolled in this prospective, double-blinded, randomized study. All patients were randomly divided into two groups based on the insertion length of the epidural catheter 2 cm (group A) or 4 cm (group B). A Tuohy needle was inserted in the lumbarspinal region with a bevel directed cephalad by use of the median approach, and then the epidural space was confirmed by the loss of resistance technique with air. While the practitioner inserted an epidural catheter into the epidural space, a blind observer checked for paresthesia or withdrawal movement. Results: In 97 included patients, 30.6% of the patients in group A (n = 49) had paresthesia, versus 31.3% in group B (n = 48). Withdrawal movements were represented in 2% and 6% of the patients in group A and group B, respectively. There was no difference in the incidence of paresthesia and withdrawal movement between the two groups. Conclusions: There is no clear relationship for the incidence of catheter-related paresthesia according to the catheter length inserted into the epidural space for epidural analgesia.
