When the general public hears the “pain clinic“, except for a few patients who have been in the pain clinic, the usual response is: “Pain clinic? Is there this kind of clinic? What kind of patients do you see?” Although the pain clinic in our hospital has been established recently In the past two decades, most of the major medical centers across the country have also set up pain clinics. In recent years, the Pain Medicine Association has also worked hard to promote the situation, but most people, even those who work in hospitals, do not know what pain clinics can do for patients. what. In the past, I have been briefed on what conditions are suitable for medical treatment in the pain clinic. This time, Pain doctor Texarkana will introduce the common interventional pain treatment in the pain clinic.
Nerve blocking refers to the use of drugs or heating and cauterizing the nerve to block the conduction of the nerve so that the sensation of pain cannot be transmitted to the brain to relieve the pain.
What Drugs Are Used?
There are two types of drugs commonly used in pain clinics to implement nerve blocking. One is the drugs that regulate nerve conduction to reduce pain. The most common is steroids. The other is drugs that completely block nerve conduction, including local anesthetics that have a short-term effect, and drugs that can destroy nerves to block nerve conduction for a long time, such as alcohol or phenol. Injections near the nerve can block the nerve. Nerves are responsible for all senses (including pain). Generally speaking, doctors will use local anesthetics to perform diagnostic blockade on patients according to the condition, that is, let the physician know which nerve conducts the patient’s pain, and then decide whether to block the nerve for a long time.
Under What Circumstances Should Steroids Be Used For Nerve Blockade?
In some diseases, such as herniated disc, rupture, spondylolisthesis, stenosis, and bone hyperplasia (commonly known as bone spurs), it may cause inflammation of cervical or lumbar nerve roots and cause pain in the upper or lower limbs, and through general medication and rehabilitation If the treatment does not respond or the effect is not good, you can consider using steroids to block nerves, which can directly inhibit nerve inflammation, and you can alleviate pain.
What Are The Side Effects Of Injecting Steroids Near The Nerves?
The more common side effects include: edema, increased blood pressure, increased blood sugar (patients with diabetes have a greater impact, and the average person has less impact), insomnia; these side effects will last about two to three days to one week.
Can Nerve Block Be Performed In An Outpatient Clinic?
It depends on the method of implementation. Generally speaking, the location of the nerve block under the guidance of X-rays is more accurate, which can get better results and reduce side effects. In some cases, even more, precise CT scanning guidance may be required, but because the radiation dose of using CT guidance is much larger than that of ordinary fluoroscopes, in order to reduce the radiation exposure of the patient, if it is not necessary, Or use the general X-ray (ie fluoroscopy) guidance. Regardless of the use of X-ray or computer tomography, due to equipment limitations, it cannot be performed in outpatient clinics and must be arranged by the physician. However, general nerve block surgery patients do not need to be hospitalized, and they can return home if there is no discomfort one to two hours after the operation is completed.
Ultrasonic Wave Guide Nerve Block:
In recent years, pain physicians have begun to apply ultrasound-guided nerve blockades to block nerves in certain areas (stellate ganglia, cervical nerve roots, cervical and lumbar facet joint nerves, coccygeal spinal epidurals). Injection, etc.), the use of ultrasound imaging guidance can be safer and there is no concern about exposure to radiation, so it can be performed in outpatient clinics, which is more convenient for patients. However, the supersonic wave guide nerve block requires skilled physicians. At present, only physicians in our hospital and several other medical centers can provide this technology.
Pulsed Radiofrequency Electromagnetic Field:
Conventional radiofrequency thermocoagulation (conventional radiofrequency thermocoagulation), which uses heat energy to accurately destroy nerve tissues and achieve the effect of nerve blockade, has been used clinically for a long time. In recent years, it has been discovered that using pulsed radio frequency electromagnetic waves to stimulate nerves may also produce analgesic effects. Because it is an intermittent current, unlike traditional high-frequency thermocoagulation, which produces high temperatures, the nerve tissue will not be destroyed, so there will be no sensory numbness or sequelae of weakness caused by nerve damage. This is also the most attractive benefit of pulsed radio frequency. The execution process is similar to traditional high-frequency thermocoagulation. Under the guidance of X-ray or ultrasonic wave guide, insert a radiofrequency electric catheter with only the most conductive tip to the nerve to be treated, and then apply pulsed radiofrequency current to it. Generally speaking, only local anesthesia is required for the entire treatment process.
