Research on ultrasound-guided real-time epidural anesthesia techniques

JRCT ID: jRCT1072240046

Registered date:07/08/2024

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: All diseases for which thoracic epidural anesthesia is indicated
• Date of first enrollment: 23/07/2024
• Target sample size: 72
• Study type: Interventional
• Intervention(s): The pre-procedure ultrasonography group is divided into two groups: the pre-procedure ultrasonography group and the real-time ultrasonography group. In the pre-procedure ultrasonography group, the target vertebral segment is identified before the procedure, and an epidural puncture is performed blindly as usual using the vanishing-resistance method. In the real-time ultrasound group, the epidural puncture is performed while always visualizing the needle tip. In both groups, a catheter is placed 4 cm into the epidural space. Successful catheter placement is confirmed by ultrasound in both groups.

Outcome(s)

• Primary Outcome: First pass success rate (epidural punctured without contacting the vertebral arch even once)
• Secondary Outcome: Number of punctures, number of redirections, procedure time, complications during the procedure (dural puncture, radiating pain), complete real-time puncture rate in the real-time group

Key inclusion & exclusion criteria

• Age minimum: >= 18age old
• Age maximum: Not applicable
• Include criteria: Patients who have obtained written research consent from the individual or a surrogate

Exclude criteria

1) Patients allergic to local anesthetics
2) Patients with communication difficulties
3) Patients who have undergone spinal surgery or have infection or metastasis in the spine
4) Patients who are on anticoagulants or have abnormal coagulation capacity.
