The Evaluation of Erector Spinae Plane Block for the Pain Control of Thoracic Postherpetic Neuralgia
Study Overview
Status
Conditions
Detailed Description
This study is single-blind because it is not possible to blind the practitioner performing the injection.
Subjects were randomly assigned to the erector spinae plane block group (group E) and the thoracic paravertebral block group (group P) by a random random number table, and the possibilities for belonging to any group were all the same and can not be artificially controlled by researchers.
Before the procedure, a resident who does not know of this study records the patient's pain and painDETECT. and on follow-up four weeks visits, PGIC scale is checked.
The erector spinae plane block or thoracic paravertebral block should be performed after receiving the informed consent of the patient.
Because of the large difference between the skilled and unskilled patients, the procedure in this study is performed by only one skilled practitioner.

---|---|
EXPERIMENTAL: erector spinae plane block group (group E)
ultrasound-guided erector spinae plane block
|
In group E, The patient was placed in a sitting position and a high-frequency linear ultrasound transducer was placed in a longitudinal orientation 3 cm lateral to the thoracic spinous process.
Three muscles were identified superficial to the hyperechoic transverse process shadow as follows: trapezius, rhomboid major, and erector spinae.
An 8-cm 22-gauge block needle was inserted in a cephalad-to-caudad direction until the tip lay in the interfascial plane between transverse process and erector spinae muscles, as evidenced by visible linear spread of fluid between erector spinae muscles and the bony acoustic shadows of the transverse process.
A total of 20 mL of 0.25% ropivacaine with dexamethasone 5mg was injected here.

ACTIVE_COMPARATOR: thoracic paravertebral block group (group P)
ultrasound-guided thoracic paravertebral block
|
2) In group P, an appropriate thoracic spinous precess is located by positioning the probe in the transverse plane.
Then the probe is moved laterally to locate the transverse process.
The probe is manipulated slightly caudad or cephala to locate the intercostal space.
The transverse process is visualized medially with the pleura dipping under the inferolateral aspect.
The internal intercostal membrane, which is contiguous with the superior costotransverse ligament, was generally seen as a thin, radiopaque line extending from the transverse process, creating a wedge-shaped pocket, which represents the thoracic paravertebral space.
A 22-gauge, facet-tip needle is advanced, in plane, from the lateral aspect of the ultrasound probe.
When the needle pierced the internal intercostal membrane, and after aspiration demonstrated the absence of air or blood, 10 mL 0.25% ropivacaine with dexamethasone 5mg deposited in 5-mL increments.

Measure Description |
Time Frame |
---|---|---|
1. Pain score (NRS)
Time Frame: Changes of Pain score from the procedure to 4 weeks

1. in both groups, the patient is asked to score the pain before the procedure and 4 weeks later. And then the change of pain score is recorded.
|
Changes of Pain score from the procedure to 4 weeks
|
2. painDETECT score
Time Frame: Changes of painDETECT score from the procedure to 4 weeks
|
2. the patient is asked to painDETECT score the pain before the procedure and 4 weeks later. And then the change of painDETECT score is recorded.
|
Changes of painDETECT score from the procedure to 4 weeks
|
3. PGIC, 7 scales(overall improvement of pain relief)
Time Frame: Changes of PGIC, 7 scales from the procedure to 4 weeks
|
3. the patient is asked to PGIC, 7 scales about overall improvement of pain relief 4 weeks later.
|
