Plain English summary of protocol

Background and study aims
This study explores whether ultrasound-guided erector spinae plane block (ESPB) can improve the surgical experience of patients undergoing PTED for lumbar disc herniation, compared to traditional local anesthesia.

Who can participate?
Adults aged 18–65 years with confirmed single-level lumbar disc herniation who have failed conservative treatment.
Participants will be excluded if they:
(1)patients with surgical contraindication; (2) multiple segments of disc herniation, vertebral infection or tumor; (3) lumbar spondylolisthesis, obvious degenerative deformities, instability, and scoliosis; (4) substantial diseases of important organs; and (5) patients who withdrew their participation.

What does the study involve?
Clinical Application of Ultrasound-guided Erector Spinae Plane Block in Percutaneous Transforaminal Endoscopic Discectomy
What are the possible benefits and risks of participating?
ESPB may provide better intraoperative comfort and stability. Risks are minimal, as both techniques are standard and widely used.

What are the possible benefits and risks of participating?
Not provided at time of registration

Where is the study run from?
The study is being conducted at the Dehua County Hospital, Fujian Province (China)

When is the study starting and how long is it expected to run for?
May 2021 to December 2021

Scientific titleA randomized controlled trial comparing ultrasound-guided erector spinae plane block versus local anesthesia for pain control and perioperative outcomes in percutaneous transforaminal endoscopic discectomy
Study objectivesUltrasound-guided erector spinae plane block (ESPB) improves intraoperative comfort, hemodynamic stability, and pain control compared to local anesthesia in PTED, without compromising surgical efficacy or increasing postoperative complications.
Ethics approval(s)

Approved 20/05/2021, Dehua County Hospital Medical Ethics Committee (No. 32 Xunzhong Town, Dehua County, Quanzhou City, Fujian Province 362500, Quanzhou, 362500, China; +86 595-23522460; jiang@gmail.com), ref: 2021L[001]

Health condition(s) or problem(s) studiedUltrasound-guided erector spinae plane block in percutaneous transforaminal endoscopic discectomy
InterventionIntervention Group (ESPB): The ultrasound-guided erector spinae plane block (ESPB) is administered once prior to surgery. No repeated dosing is involved.

Control Group (LA): Local anesthesia is similarly administered once before surgery.

All participants are followed for a total of 6 months post-operation, with assessments conducted at baseline (pre-operation), 3 months, and 6 months post-operation. These include measurements of pain (VAS), functional status (ODI), and clinical outcomes (modified Macnab criteria).
Intervention typeProcedure/Surgery
Primary outcome measure1. Intraoperative VAS scores (Visual Analog Scale) at foraminoplasty, annulus fibrosus operation, and end of surgery.
2. Measured using VAS during the procedure.
Secondary outcome measures1. Mean arterial pressure (MAP) and heart rate (HR) at four perioperative time points (T0–T3)
2. Operation time, intraoperative blood loss, length of hospital stay
3. Modified Macnab criteria at 3-month follow-up
4. Pre- and postoperative VAS and ODI scores at 3 and 6 months
5. Reoperation willingness on post-op Day 1
