Objectives

Narrative objectives1

Epidural catheters inserted via the back for postoperative analgesia are widely used for postoperative pain management. However, bleeding at the catheter insertion site and catheter migration may occur over time, potentially hindering the continuation of epidural analgesia.
This study aimed to assess the incidence of these complications during epidural catheterization, evaluate the impact of preventive measures, and compare the occurrence of these events before and after their implementation.

Assessment

Primary outcomes

The external length of the epidural catheter from the skin insertion site will be measured immediately after catheter placement, at the end of surgery, and during the morning round on postoperative day 1. In addition, the severity of insertion-site bleeding will be assessed using a five-point grading scale.
To prevent catheter migration and insertion-site bleeding, the following interventions will be implemented: (1) creation of a subcutaneous tunnel approximately 2 cm in length adjacent to the epidural catheter insertion site, and (2) application of a biocompatible tissue adhesive to the insertion site.
Patients will be allocated to one of the following four groups:
Group A: Standard epidural catheter placement alone
Group B: Application of biocompatible tissue adhesive to the insertion site following epidural catheter placement
Group C: Creation of an approximately 2-cm subcutaneous tunnel following epidural catheter placement
Group D: Creation of an approximately 2-cm subcutaneous tunnel followed by application of biocompatible tissue adhesive
The primary outcome measures will be changes in the external catheter length and the severity of insertion-site bleeding. These outcomes will be compared among the four groups.
