The lumbar back anesthesia test is to check for tenderness after topical anesthesia, which is common in deep tissue organic damage. This test is often used for hierarchical positioning of low back pain. Note on the lumbar back anesthesia test: inappropriate population: people who are sensitive to anesthesia. Contraindications before examination: Check for abnormal reactions to anesthetics.

Basic Information

Specialist classification: growth and development check classification: physical examination

Applicable gender: whether men and women apply fasting: not fasting

Analysis results:

Below normal:

Normal value:
no

Above normal:

negative:
The result of the test was negative. No pain occurred after anesthesia.

Positive:
0.5%-1.0% procaine 10-20ml line of lower back pain points, if injected under the skin, the pain disappears, mostly fascia ligament injury; if injected into the lamina, the pain disappears, mostly paravertebral muscle disease Loss; if after the above injection, the pain is as before, it is more likely to be a disease in the spinal canal. When the ethyl chloride refrigerant is 30 cm away from the pain point skin, it is sprayed for a short time (generally no more than 30 s). After the surface anesthesia, there is still tenderness, often suggesting deep tissue organic damage. This test is often used for hierarchical positioning of low back pain.

Tips: You should face it positively and actively cooperate with the inspection. Normal value

The result of the test was negative. No pain occurred after anesthesia.

Clinical significance

Abnormal results:

0.5%-1.0% procaine 10-20ml line of lower back pain points, if injected under the skin, the pain disappears, mostly fascia ligament injury; if injected into the lamina, the pain disappears, mostly paravertebral muscle disease Loss; if after the above injection, the pain is as before, it is more likely to be a disease in the spinal canal.

When the ethyl chloride refrigerant is 30 cm away from the pain point skin, it is sprayed for a short time (generally no more than 30 s). After the surface anesthesia, there is still tenderness, often suggesting deep tissue organic damage. This test is often used for hierarchical positioning of low back pain.

People who need to be examined: people with abnormal pain at the waist.

Positive results may be diseases: chronic strain of the neck and back fascia fibrositis, lumbar spinal stenosis considerations

Contraindications before examination: Check for abnormal reactions to anesthetics.

Requirements for inspection: Check the feelings of relaxation, should face positively, and actively cooperate with the inspection.

Inspection process

1, with 0.5% -1.0% procaine 10-20ml line back pain points closed.

2. Spray with a short-term (generally no more than 30 s) spray of 30 ml of the ethyl chloride refrigerant from the pain point.

Not suitable for the crowd

People who are sensitive to anesthesia.

Adverse reactions and risks

Generally not.
